Engine Oil

Checking Engine Oil

It is a good idea to check the engine oil level at each fuel fill. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.

Turn off the engine and give the oil several minutes to drain back into the oil pan. If this is not done, the oil dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.

When to Add Engine Oil

If the oil is below the cross-hatched area at the tip of the dipstick, add at least one quart/liter of the recommended oil. This section explains what kind of oil to use.

Notice:
Do not add too much oil. If the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged.
Add enough oil to put the level somewhere in the proper operating range in the cross-hatched area. Push the dipstick all the way back in when through.

What Kind of Engine Oil to Use

Look for three things:

GM6094M
Use only an oil that meets GM Standard GM6094M.
SAE 5W-30
SAE 5W-30 is best for the vehicle. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50.
American Petroleum Institute (API) starburst symbol
Oils meeting these requirements should have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API).

Notice:
Use only engine oil identified as meeting GM Standard GM6094M and showing the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by the vehicle warranty.

Cold Temperature Operation

If in an area of extreme cold, where the temperature falls below −20°F (−29°C), use either an SAE 5W-30 synthetic oil or an SAE 0W-30 engine oil. Both provide easier cold starting for the engine at extremely low temperatures. Always use an oil that meets the required specification, GM6094M.

Engine Oil Additives / Engine Oil Flushes

Do not add anything to the oil. The recommended oils with the starburst symbol that meet GM standards are all that is needed for good performance and engine protection.
Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty.

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably.
For the oil life system to work properly, the system must be reset every time the oil is changed.

When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A “Change Engine Oil Soon” message comes on. Change the oil as soon as possible within the next 600 miles (1,000 km). It is possible that, if driving under the best conditions, the oil life system might not indicate that an oil change is necessary for over a year.

However, the engine oil and filter must be changed at least once a year and at this time the system must be reset. Your dealer/retailer has trained service people who will perform this work using genuine parts and reset the system. It is also important to check the oil regularly and keep it at the proper level.

If the system is ever reset accidentally, the oil must be changed at 3,000 miles (5,000 km) since the last oil change. Remember to reset the oil life system whenever the oil is changed.

How to Reset the Engine Oil Life System

The Engine Oil Life System calculates when to change the engine oil and filter based on vehicle use. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where the oil is changed prior to a “Change Engine Oil Soon” message being turned on, reset the system.

To reset the Engine Oil Life System:

Turn the ignition to ON/RUN, with the engine off.
Press the vehicle information button until “Oil Life Remaining” displays.
Press and hold the set/reset button until “100%” is displayed. Three chimes sound and the “Change Engine Oil Soon” message goes off.
Turn the key to LOCK/OFF.

If the “Change Engine Oil Soon” message comes back on when the vehicle is started, the engine oil life system has not reset. Repeat the procedure.

What to Do with Used Oil

Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil.

Automatic Transmission Fluid

It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to the dealer/retailer and have it repaired as soon as possible.

Notice:
Use of the incorrect automatic transmission fluid may damage the vehicle, and the damages may not be covered by the vehicle’s warranty. Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants

The transmission fluid will not reach the end of the dipstick unless the transmission is at operating temperature. If you need to check the transmission fluid level, please take the vehicle to your dealer/retailer.

Cooling System

The cooling system allows the engine to maintain the correct working temperature.

A. Engine Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Cooling Fans

{WARNING}
An electric engine cooling fan under the hood can start up even when the engine is not running and can cause injury. Keep hands, clothing, and tools away from any underhood electric fan.

{WARNING}
Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned.
Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.

Notice:
Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 50,000 km (30,000 miles) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL® (silicate-free) coolant in the vehicle.

Engine Coolant

The cooling system in the vehicle is filled with DEX-COOL® engine coolant. The coolant is designed to remain in the vehicle for five years or 240,000 km (150,000 miles), whichever occurs first.
The following explains the cooling system and how to check and add coolant when it is low.

What to Use

{WARNING}
Adding only plain water to the cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. The vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, the engine could get too hot but you would not get the overheat warning. The engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant.

Use a 50/50 mixture of clean, drinkable water and DEX-COOL coolant. If using this mixture, nothing else needs to be added. This mixture:

Gives freezing protection down to −37°C (−34°F), outside temperature.
Gives boiling protection up to 129°C (265°F), engine temperature.
Protects against rust and corrosion.
Will not damage aluminum parts.
Helps keep the proper engine temperature.

Notice:
If an improper coolant mixture is used, the engine could overheat and be badly damaged. The repair cost would not be covered by the vehicle warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core, and other parts.

Notice:
If extra inhibitors and/or additives are used in the vehicle’s cooling system, the vehicle could be damaged. Use only the proper mixture of the engine coolant listed in this manual for the cooling system.

Checking Coolant

The vehicle must be on a level surface when checking the coolant level.

Check to see if coolant is visible in the coolant recovery tank. If the coolant inside the coolant recovery tank is boiling, do not do anything else until it cools down. If coolant is visible but the coolant level is not at or above the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL coolant at the coolant recovery tank, but be sure the cooling system is cool before this is done.

The coolant recovery tank cap has this symbol on it.
When the engine is cold, the coolant level should be at or above the FULL COLD line marked on the recovery tank.

When the engine is hot, the level could be higher than the FULL COLD line. If the coolant is below the FULL COLD line when the engine is hot, there could be a leak in the cooling system.
If the coolant is low, add the coolant or take the vehicle to a dealer/retailer for service.

How to Add Coolant to the Recovery Tank

{WARNING}
You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine.

Notice:
This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause the engine to overheat and be severely damaged.

If coolant is needed, add the proper DEX-COOL® coolant mixture at the coolant recovery tank.

How to Add Coolant to the Radiator

{WARNING}
An electric engine cooling fan under the hood can start up even when the engine is not running and can cause injury. Keep hands, clothing, and tools away from any underhood electric fan.

{WARNING}
Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the surge tank pressure cap — even a little — they can come out at high speed. Never turn the cap when the cooling system, including the surge tank pressure cap, is hot. Wait for the cooling system and surge tank pressure cap to cool if you ever have to turn the pressure cap.

If coolant is needed, add the proper mixture directly to the radiator, but be sure the cooling system is cool before this is done.

Detach fasteners and lift off the panel that covers the radiator cap.
Remove the radiator pressure cap when the cooling system, including the upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one full turn. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left in the system.
Keep turning the pressure cap slowly and remove it.
Fill the radiator to the base of the filler neck with the proper DEX-COOL coolant mixture.
When coolant begins to flow out of the filler neck, reinstall the pressure cap. Be sure to secure it tightly.

Fill the coolant recovery tank to the FULL COLD mark.
Reinstall the cap on the coolant recovery tank but leave the radiator pressure cap off.

Start the engine and let it run until the upper radiator hose feels warm. Any time during this procedure, watch out for the engine cooling fan(s).
If the coolant level inside the radiator filler neck is low, add more of the proper DEX-COOL coolant mixture through the filler neck until the level is back up to the base of the filler neck. Replace the pressure cap. Be sure to secure it tightly.

Notice:
If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured.

Engine Overheating

The vehicle has several indicators to warn of engine overheating. There is an engine coolant temperature gauge on the instrument panel cluster.

The vehicle may also display an ENGINE OVERHEATED IDLE ENGINE and ENGINE OVERHEATED STOP ENGINE message in the Driver Information Center (DIC).

You may decide not to lift the hood when this warning appears, but instead get service help right away. If you do decide to lift the hood, make sure the vehicle is parked on a level surface.
Then check to see if the engine cooling fans are running. If the engine is overheating, both fans should be running. If they are not, do not continue to run the engine and have the vehicle serviced.

Notice:
Engine damage from running the engine without coolant is not covered by the warranty.

Notice:
If the engine catches fire while driving with no coolant, the vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty.

If Steam Is Coming From The Engine Compartment

{WARNING}
Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood.
If you keep driving when the vehicle’s engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop the engine if it overheats, and get out of the vehicle until the engine is cool.

If No Steam Is Coming From The Engine Compartment
If an engine overheat warning is displayed but no steam can be seen or heard, the problem may not be too serious. Sometimes the engine can get a little too hot when the vehicle:

Climbs a long hill on a hot day.
Stops after high-speed driving.
Idles for long periods in traffic.
Tows a trailer.

If the overheat warning is displayed with no sign of steam:

Turn the air conditioning off.
Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as necessary.
If in a traffic jam, shift to N (Neutral), otherwise, shift to the highest gear while driving — D (Drive) or L (Low).

If the temperature overheat gauge is no longer in the overheat zone or an overheat warning no longer displays, the vehicle can be driven. Continue to drive the vehicle slow for about 10 minutes. Keep a safe vehicle distance from the car in front of you. If the warning does not come back on, continue to drive normally.

If the warning continues, pull over, stop, and park the vehicle right away.
If there is no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down. Also, see “Overheated Engine Protection Operating Mode” next in this section.

Overheated Engine Protection Operating Mode

This emergency operating mode lets the vehicle be driven to a safe place in an emergency situation. If an overheated engine condition exists, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage.
In this mode, there is a significant loss in power and engine performance. The temperature gauge indicates an overheat condition exists. Driving extended distances and/or towing a trailer in the overheat protection mode should be avoided.

Notice:
After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil, and reset the oil life system. See Engine Oil on page 10-8.

Power Steering Fluid

The power steering fluid reservoir is located under the engine cover on the passenger side of the vehicle.

When to Check Power Steering Fluid

It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

How to Check Power Steering Fluid

To check the power steering fluid:

Turn the key off and let the engine compartment cool down.
Remove the engine cover.
Wipe the cap and the top of the reservoir clean.
Unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it.
Remove the cap again and look at the fluid level on the dipstick. The fluid level should be somewhere between MAX and MIN line on the dipstick in room temperature. If the fluid is on or below MIN line, you should add fluid close to MAX Line.

What to Use
To determine what kind of fluid to use, see Recommended Fluids and Lubricants. Always use the proper fluid.

Notice:
Use of the incorrect fluid may damage the vehicle and the damages may not be covered by the vehicle’s warranty. Always use the correct fluid listed in Recommended Fluids and Lubricants .

Washer Fluid

What to Use
When adding windshield washer fluid, be sure to read the manufacturer’s instructions before use. If the vehicle will be operating in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.

Adding Washer Fluid

When the windshield washer fluid reservoir is low, a WASHER FLUID LOW ADD FLUID message will be displayed on the Driver Information Center (DIC). Open the cap with the washer symbol on it. Add washer fluid until the tank is full.

Notice:

When using concentrated washer fluid, follow the manufacturer’s instructions for adding water.
Do not mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage the washer fluid tank and other parts of the washer system. Also, water does not clean as well as washer fluid.
Fill the washer fluid tank only three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full.
Do not use engine coolant (antifreeze) in the windshield washer. It can damage the vehicle’s windshield washer system and paint.

Brakes

This vehicle has disc brakes.
Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or be heard all the time the vehicle is moving, except when applying the brake pedal firmly.

{WARNING}
The brake wear warning sound means that soon the brakes will not work well. That could lead to an accident. When the brake wear warning sound is heard, have the vehicle serviced.

Notice:
Continuing to drive with worn-out brake pads could result in costly brake repair.

Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes.
Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to torque specifications in Capacities and Specifications. Brake linings should always be replaced as complete axle sets.

Brake Pedal Travel
See your dealer/retailer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service might be required.

Brake Adjustment
Every time the brakes are applied, with or without the vehicle moving, the brakes adjust for wear.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. The vehicle was designed and tested with top-quality brake parts. When parts of the braking system are replaced, be sure to get new, approved replacement parts. If this is not done, the brakes might not work properly. For example, installing disc brake pads that are wrong for the vehicle, can change the balance between the front and rear brakes — for the worse. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed.

Brake Fluid

The brake master cylinder reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap.
There are only two reasons why the brake fluid level in the reservoir might go down:

The brake fluid level goes down because of normal brake lining wear. When new linings are installed, the fluid level goes back up.
A fluid leak in the brake hydraulic system can also cause a low fluid level. Have the brake hydraulic system fixed, since a leak means that sooner or later the brakes will not work well.

Do not top off the brake fluid. Adding fluid does not correct a leak. If fluid is added when the linings are worn, there will be too much fluid when new brake linings are installed. Add or remove brake fluid, as necessary, only when work is done on the brake hydraulic system.

If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system.

When the brake fluid falls to a low level, the brake warning light comes on.

What to Add
Use only new DOT 3 brake fluid from a sealed container.
Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir.

{WARNING}
With the wrong kind of fluid in the brake hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake fluid.

Notice:

Using the wrong fluid can badly damage brake hydraulic system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake hydraulic system can damage brake hydraulic system parts so badly that they will have to be replaced. Do not let someone put in the wrong kind of fluid.
If brake fluid is spilled on the vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on the vehicle. If you do, wash it off immediately.
