Engine Oil
To ensure proper engine performance and long life, careful attention must be paid to engine oil. Following these simple, but important steps will help protect your investment: . Use engine oil approved to the proper
specification and of the proper viscosity grade. See “Selecting the Right Engine Oil” in this section.
. Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section.
. Change the engine oil at the appropriate time. See Engine Oil Life System 0 277.
. Always dispose of engine oil properly. See “What to Do with Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly, every 650 km (400 mi), especially prior to a long trip. The engine oil dipstick handle is a loop. See Engine Compartment Overview 0 272 for the location.
Warning
The engine oil dipstick handle may be hot; it could burn you. Use a towel or glove to touch the dipstick handle.
If a low oil Driver Information Center (DIC) message displays, check the oil level.
Follow these guidelines:
. To get an accurate reading, park the
vehicle on level ground. Check the engine oil level after the engine has been off for at least two hours. Checking the engine oil level on steep grades or too soon after engine shutoff can result in incorrect readings. Accuracy improves when checking a cold engine prior to starting. Remove the dipstick and check the level.
. If unable to wait two hours, the engine must be off for at least 15 minutes if the engine is warm, or at least 30 minutes if the engine is not warm. Pull out the dipstick, wipe it with a clean 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
2.0L L4 Turbo Engine
3.6L V6 Engine
If the oil is below the cross-hatched area at the tip of the dipstick and the engine has been off for at least 15 minutes, add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” later in this section for an explanation of what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications 0 361.
Caution
Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If the oil level is above the operating range (i.e., 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. Drain the excess oil or limit driving of the vehicle, and seek a service professional to remove the excess oil.
See Engine Compartment Overview 0 272 for the location of the engine oil fill cap. Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through.
Selecting the Right Engine Oil
Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants 0 356.
Specification
Use full synthetic engine oils that meet the dexos1 specification. Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo. See www.gmdexos.com.
Caution
Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty.
Viscosity Grade
For the 2.0L L4 Turbo engine, use SAE 0W-20 viscosity grade engine oil. For the 3.6L V6 engine, use SAE 5W-30 viscosity grade engine oil. Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −29 °C (−20 °F), an SAE 0W-30 oil may be used. An
Vehicle Care 277
oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. When selecting an oil of the appropriate viscosity grade, it is recommended to select an oil of the correct specification. See “Specification” earlier in this section.
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The recommended oils meeting the dexos1 specification 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.
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 or 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.
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 a combination of factors which include engine revolutions, engine temperature, and miles driven. 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 1 000 km (600 mi). It is possible that, if driving under the best conditions, the oil life system might indicate that an oil change is not
necessary for up to a year. The engine oil and filter must be changed at least once a year and, at this time, the system must be reset. Your dealer has trained service people who will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level. If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) 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
Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. To reset the system: 1. Display the REMAINING OIL LIFE on the
DIC. See Driver Information Center (DIC) (Base Level) 0 116 or Driver Information Center (DIC) (Midlevel and Uplevel) 0 118.
2. Press and hold V on the DIC while the Oil Life display is active. The oil life will change to 100%.
278 Vehicle Care
If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life system has not been reset. Repeat the procedure.
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 and have it repaired as soon as possible. Change the fluid at the intervals listed in Maintenance Schedule 0 348, and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants 0 356.
Caution
Use of the incorrect automatic transmission fluid may damage the vehicle, and the damage may not be covered by the vehicle warranty. Always use the correct automatic transmission fluid. See Recommended Fluids and Lubricants 0 356.
If you need to check the transmission fluid level, take the vehicle to your dealer.
Engine Air Filter Life System
If equipped, this feature provides the engine air filter’s remaining life and best timing for a change. The timing to change an engine air filter depends on driving and environmental conditions.
When to Change Engine Air Filter
When the Driver Information Center (DIC) displays a message to replace the engine air filter at the next oil change, follow this timing. When the DIC displays a message to replace the engine air filter soon, replace the engine air filter at the earliest convenience. The system must be reset after the engine air filter is changed. If the DIC displays a message to check the engine air filter system, see your dealer.
How to Reset Engine Air Filter Life System
To reset: 1. Place the vehicle in P (Park).
2. Display the Air Filter Life on the DIC. See Driver Information Center (DIC) (Base Level) 0 116 or Driver Information Center (DIC) (Midlevel and Uplevel) 0 118.
3. Press p to move to the Reset/Disable display area. Select Reset then press V.
4. Press V to confirm to reset.

The cooling system allows the engine to maintain the correct working temperature.
2.0L L4 Engine
1. Engine Cooling Fan (Out of View) 2. Engine Coolant Surge Tank and Pressure Cap
3.6L V6 Engine
1. Engine Cooling Fan (Out of View) 2. Engine Coolant Surge Tank and Pressure Cap
Warning
An underhood electric fan 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
Do not touch heater or radiator hoses, or other engine parts. They can be very hot and can burn you. Do not run the engine if there is a leak; all coolant could leak out. That could cause an engine fire and can burn you. Fix any leak before driving the vehicle.
Engine Coolant
The cooling system in the vehicle is filled with DEX-COOL engine coolant. This coolant needs to be checked and replaced at appropriate intervals. See Maintenance Schedule 0 348. The following explains the cooling system and how to check and add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating 0 284.
What to Use
Warning
Do not touch heater or radiator hoses, or other engine parts. They can be very hot and can burn you. Do not run the engine if there is a leak; all coolant could leak out. That could cause an engine fire and can burn you. Fix any leak before driving the vehicle.
Use a 50/50 mixture of clean, drinkable water and DEX-COOL coolant. 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.
Caution
Do not use anything other than a mix of DEX-COOL coolant that meets GM Standard GMW3420 and clean, drinkable water. Anything else can cause damage to the engine cooling system and the vehicle, which would not be covered by the vehicle warranty.
Never dispose of engine coolant by putting it in the trash, pouring it on the ground, or into sewers, streams, or bodies of water. Have the coolant changed by an authorized service center, familiar with legal requirements regarding used coolant disposal. This will help protect the environment and your health.
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 surge tank. If the coolant inside the coolant surge tank is boiling, do not do anything else until it cools down. See Engine Overheating 0 284.
The coolant surge tank is located in the engine compartment on the driver side of the vehicle. See Engine Compartment Overview 0 272.
Warning
Spilling coolant on hot engine parts can burn you. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough.
Warning
Steam and scalding liquids from a hot cooling system are under pressure. Turning the pressure cap, even a little, can cause them to come out at high speed and you could be burned. Never turn the cap when the cooling system, including the pressure cap, is hot. Wait for the cooling system and pressure cap to cool.
Warning
Plain water, or other liquids such as alcohol, can boil before the proper coolant mixture will. With plain water or the wrong mixture, the engine could get too hot but there would not be an overheat warning. The engine could catch fire and you or others could be burned.
Caution
Failure to follow the specific coolant fill procedure could cause the engine to overheat and could cause system damage. If coolant is not visible in the surge tank, contact your dealer.
If no problem is found, check to see if coolant is visible in the coolant surge tank. If coolant is visible but the coolant level is not at or above the indicated mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL coolant. Be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it.
How to Add Coolant to the Coolant Surge Tank (3.6L V6 Engine Only)
1. Remove the coolant surge tank pressure
cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one-quarter of a turn. If you hear a hiss, wait for that to stop. This will allow any pressure still left to be vented out the discharge hose.
2. Keep turning the pressure cap slowly and remove it.
3. Fill the coolant surge tank with the proper mixture to the indicated level mark.
4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the indicated level mark.
5. Replace the pressure cap tightly. 6. Verify coolant level after the engine is
shut off and the coolant is cold. If necessary, repeat coolant fill procedure Steps 1–6. If the coolant still is not at the proper level when the system cools down again, see your dealer.
Caution
If the pressure cap is not tightly installed, coolant loss and engine damage may occur. Be sure the cap is properly and tightly secured.
Automatic Coolant Service Fill (2.0L L4 Engine Only)
If equipped, this feature assists in filling and removing air from the cooling system after service of components or when coolant is added after being too low. To activate the fill and air removal process: 1. With a cold system, disconnect the vent
line from the port near the cap on the surge tank. Add coolant to the indicated mark on the surge tank.
2. Reconnect the vent line to the surge tank and replace the cap on the surge tank.
3. Connect the vehicle to a battery charger. 4. Put the vehicle in Service Mode. See
Ignition Positions 0 213. 5. Turn off the air conditioning. 6. Set the parking brake. 7. At the same time, press the accelerator
and the brake for automatic transmission vehicles for two seconds, then release.
At the end of the cycle, check the coolant level in the surge tank and add coolant, if it is low. Turn off the vehicle, allow the Engine Control Module (ECM) to go to sleep, about two minutes, and repeat steps 3-7. Listen for pump activation and movement of the control valves while watching the level of the tank. If the tank empties, turn the ignition off, carefully remove the surge tank cap, refill to the indicated mark and repeat steps 3-6. The fill and air removal process will run for approximately 10 minutes.
284 Vehicle Care Engine Overheating
The vehicle has several indicators to warn of the engine overheating. There is an engine coolant temperature gauge on the instrument cluster. See Engine Coolant Temperature Gauge 0 105. The vehicle may also display a message on the Driver Information Center (DIC). If the decision is made not to lift the hood when this warning appears, get service help right away. See Roadside Assistance Program 0 368. If the decision is made to lift the hood, make sure the vehicle is parked on a level surface. Then check to see if the engine cooling fan is running. If the engine is overheating, the fan should be running. If it is not, do not continue to run the engine. Have the vehicle serviced.
Caution
Do not run the engine if there is a leak in the engine cooling system. This can cause a loss of all coolant and can damage the system and vehicle. Have any leaks fixed right away.
If Steam Is Coming from the Engine Compartment
Warning
Steam and scalding liquids from a hot cooling system are under pressure. Turning the pressure cap, even a little, can cause them to come out at high speed and you could be burned. Never turn the cap when the cooling system, including the pressure cap, is hot. Wait for the cooling system and pressure cap to 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.
If the overheat warning is displayed with no sign of steam: 1. Turn the air conditioning off. 2. Turn the heater on to the highest
temperature and to the highest fan speed. Open the windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral), and let the engine idle.
If the engine coolant temperature gauge is no longer in the overheated area, the vehicle can be driven. Continue to drive the vehicle slowly for about 10 minutes. Keep a safe distance from the vehicle in front. If the warning does not come back on, continue to drive normally and have the cooling system checked for proper fill and function. 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.
Vehicle Care 285 Washer Fluid What to Use
When windshield washer fluid is needed, be sure to read the manufacturer's instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.
Adding Washer Fluid
Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview 0 272 for reservoir location.
Caution
. Do not use washer fluid that contains
any type of water repellent coating. This can cause the wiper blades to chatter or skip.
. Do not use engine coolant (antifreeze) in the windshield washer. It can damage the windshield washer system and paint.
. 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.
. When using concentrated washer fluid, follow the manufacturer instructions for adding water.
. 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.
Brakes
Disc brake linings have built-in wear indicators that make a high-pitched warning sound when the brake linings are worn and new linings are needed. The sound can come and go or can be heard all the time when 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 a crash. When the brake wear warning sound is heard, have the vehicle serviced.
Caution
Continuing to drive with worn-out brake linings could result in costly brake repairs.
Some driving conditions or climates can cause a brake squeal when the brakes are first applied, clearing up following several applications. This does not mean something is wrong with the brakes.
286 Vehicle Care
Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake linings for wear and evenly tighten wheel nuts in the proper sequence to torque specifications. See Capacities and Specifications 0 361. Brake pads should be replaced as complete axle sets.
Brake Pedal Travel
See your dealer 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 may be required.
Replacing Brake System Parts
Always replace brake system parts with new, approved replacement parts. If this is not done, the brakes may not work properly. The braking performance can change in many ways if the wrong brake parts are installed or if parts are improperly installed.
Brake Fluid
The brake master cylinder reservoir is filled with GM approved DOT 4 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview 0 272 for the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a level surface, the brake fluid level should be between the minimum and maximum marks on the brake fluid reservoir. There are only two reasons why the brake fluid level in the reservoir may go down: . Normal brake lining wear. When new
linings are installed, the fluid level goes back up.
. A fluid leak in the brake hydraulic system. Have the brake hydraulic system fixed. With a leak, the brakes will not work well.
Always clean the brake fluid reservoir cap and the area around the cap before removing it. 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 fluid, as necessary, only when work is done on the brake hydraulic system.
Warning
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. See Brake System Warning Light 0 109. Brake fluid absorbs water over time which degrades the effectiveness of the brake fluid. Replace brake fluid at the specified intervals to prevent increased stopping distance. See Maintenance Schedule 0 348.
Vehicle Care 287 What to Add
Use only GM approved DOT 4 brake fluid from a clean, sealed container. See Recommended Fluids and Lubricants 0 356.
Warning
The wrong or contaminated brake fluid could result in damage to the brake system. This could result in the loss of braking leading to a possible injury. Always use the proper GM approved brake fluid.
Caution
If brake fluid is spilled on the vehicle's painted surfaces, the paint finish can be damaged. Immediately wash off any painted surface.
Battery - North America
The original equipment battery is maintenance free. Do not remove the cap and do not add fluid. Refer to the replacement number on the original battery label when a new battery is needed. For replacement of the battery, see your dealer.
Stop/Start System
The vehicle has a Stop/Start system to shut off the engine to help conserve fuel. See Stop/Start System 0 215. It has an Absorbed Glass Mat (AGM) 12-volt battery. Installation of a standard 12-volt battery will result in reduced 12-volt battery life. When using a 12-volt battery charger on the 12-volt AGM battery, some chargers have an AGM battery setting on the charger. If available, use the AGM setting on the charger, to limit charge voltage to 14.8 volts.
{ Warning WARNING: Battery posts, terminals and related accessories can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling. For more information go to www.P65Warnings.ca.gov.
See the warning on the back cover.
Vehicle Storage
Warning
Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you are not careful. See Jump Starting - North America 0 332 for tips on working around a battery without getting hurt.
Infrequent Usage: Remove the black, negative (−) cable from the battery to keep the battery from running down. Extended Storage: Remove the black, negative (−) cable from the battery or use a battery trickle charger.
All-Wheel Drive Transfer Case
Under normal driving conditions, transfer case fluid does not require maintenance unless there is a fluid leak or unusual noise. If required, have the transfer case serviced by your dealer.
288 Vehicle Care Park Brake and P (Park) Mechanism Check
Warning
When you are doing this check, the vehicle could begin to move. You or others could be injured and property could be damaged. Make sure there is room in front of the vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake. . To check the parking brake's holding
ability: With the engine running and the transmission in N (Neutral), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only.
. To check the P (Park) mechanism's holding ability: With the engine running, shift to P (Park). Then release the parking brake followed by the regular brake.
Contact your dealer if service is required.
Wiper Blade Replacement
