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.

cover.

5. Reverse Steps 1 through 4 to

reinstall engine cover. Engine Cover (CTS-V)

To remove: The engine cover consists of two pieces. Only the larger front piece needs to be removed to access the engine oil and power steering fill caps.

The engine oil dipstick handle is a yellow loop. See Engine Compartment Overview on page 9‑6 for the location of the engine oil dipstick. 1. 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.

2. 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 liter/quart of the recommended oil. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 11‑2 .

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.

See Engine Compartment Overview on page 9‑6 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.

What Kind of Engine Oil to Use Look for three things: . GM4718M

This vehicle's engine requires a special oil meeting GM Standard GM4718M. Oils meeting this standard may be identified as synthetic. However, not all synthetic oils will meet this GM standard. Use only an oil that meets GM Standard GM4718M.

Notice: Using oils that do not have the GM4718M Standard designation can cause engine damage not covered by the vehicle warranty. . 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.

Vehicle Care

9-11

. 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).

This vehicle's engine was filled at the factory with a Mobil 1® synthetic oil meeting all requirements for this vehicle.

9-12

Vehicle Care

Substitute Engine Oil: When adding oil to maintain engine oil level, oil meeting GM Standard GM4718M might not be available. You can add substitute oil designated SAE 5W-30
with the starburst symbol at all temperatures. Substitute oil not meeting GM Standard GM4718M should not be used for an oil change. 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. See Engine Oil Messages on page 4‑40 . Change the oil as soon as possible within the next 1 000 km (600 miles). 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 5 000 km (3,000 miles) 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. Turn the ignition to ON/RUN with

the engine off.

2. Fully press and release the

accelerator pedal three times within five seconds. If the “Change Engine Oil Soon” message is not on, the system is reset.

The system is reset when the “Change Engine Oil Soon” message is off.

What to Do with Used Oil Used engine oil contains elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags. 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

How to Check 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 service department and have it repaired as soon as possible. There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, it should be done at the dealer/retailer service department. Contact your dealer/ retailer for additional information or the procedure can be found in the service manual. To purchase a service manual, see Service Publications Ordering Information on page 12‑12.

9-14

Vehicle Care

Change the fluid and filter at the intervals listed in Scheduled Maintenance on page 10‑3 , and be sure to use the fluid listed in Recommended Fluids and Lubricants on page 10‑7.

Manual Transmission Fluid It is not necessary to check the manual transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to a dealer/ retailer for service. Have it repaired as soon as possible. You may also have the fluid level checked by your dealer/retailer when the oil is changed. See Recommended Fluids and Lubricants on page 10‑7 for the proper fluid to use.

Hydraulic Clutch It is not necessary to regularly check clutch fluid unless you suspect there is a leak in the system. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. When to Check and What to Use

The hydraulic clutch fluid reservoir cap has this symbol on it. See Engine Compartment Overview on page 9‑6 for reservoir location.

Refer to the Maintenance Schedule for the proper fluid to use. See Recommended Fluids and Lubricants on page 10‑7 . The fluid requires changing every two years. See Scheduled Maintenance on page 10‑3 . How to Check and Add Fluid Visually check the clutch fluid reservoir to make sure the fluid level is at the MIN (minimum) line on the side of the reservoir. The hydraulic clutch fluid system should be closed and sealed. Do not remove the cap to check the fluid level or to top-off the fluid level. Remove the cap only when necessary to add the proper fluid until the level reaches the MIN line.

How to Inspect the Engine Air Cleaner/Filter To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required. To inspect or replace the engine air cleaner/filter: 1. Turn the ignition off.

Engine Air Cleaner/Filter The engine air cleaner/filter is in the engine compartment on the driver side of the vehicle, near the front. See Engine Compartment Overview on page 9‑6 for more information on location. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the Maintenance II intervals and replace it at the first oil change after each 80 000 km (50,000 mile) interval. See Scheduled Maintenance on page 10‑3 for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change.

Cooling System The cooling system allows the engine to maintain the correct working temperature. When you decide it is safe to lift the hood, here is what you will see:

A. Electric Engine Cooling Fan(s)

(Out of View)

B. Coolant Surge Tank and

Pressure Cap

{ 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 for all engines and the intercooler is filled with DEX-COOL®. This 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. If there is a problem with engine overheating, see Engine Overheating on page 9‑23 .

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.

Vehicle Care

9-19

Checking Coolant The vehicle must be on a level surface when checking the coolant level. The engine coolant reservoir is located in the engine compartment on the driver side of the vehicle. See Engine Compartment Overview on page 9‑6 . Check to see if coolant is visible in the surge tank. If the coolant inside the surge 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 surge tank, but be sure the cooling system is cool before this is done. See Engine Coolant on page 9‑18
for more information.

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.

9-20

Vehicle Care

If the engine is warm or hot, the coolant level should be at or above the FROID/FULL COLD line on the side of the coolant surge tank. If the engine is cold, the coolant level should be near the FROID/FULL COLD line on the side of the coolant surge tank. If it is not, there could be a leak in the cooling system. How to Add Coolant to the Surge 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.

{ 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 DEX-COOL® coolant mixture at the coolant surge tank. If no coolant is visible in the surge tank, add coolant as follows: 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 turn and then stop. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.

Vehicle Care

9-21

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 FROID/FULL COLD line on the side of the coolant surge tank. 5. Then replace the pressure cap.

Be sure the pressure cap is hand-tight and fully seated.

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. Recheck the coolant level in the bottle next time you use your vehicle to insure the system is full when cold. See Engine Coolant on page 9‑18 .

the proper mixture, to slightly above the FROID/FULL COLD line on the side of the coolant surge tank.

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. The upper radiator hose is the top hose coming out of the radiator, on the passenger side of the vehicle. Watch out for the engine cooling fans.

Checking Coolant in the Intercooler System (CTS-V) The vehicle must be on a level surface when checking the coolant level. The super charged engine intercooler coolant fill neck is located in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview on page 9‑6. On the coolant fill neck, there is a cold fill region between the two horizontal lines shown. Check to see if coolant is visible in the coolant fill neck. If the coolant is not visible or below the cold fill region in the fill neck, add a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant at the coolant fill bottle, but be sure the cooling system is cool before this is done.

Adding Coolant to the Intercooler System Coolant (CTS-V)

2. Then keep turning the pressure

cap slowly and remove it.

3. Add the proper DEX-COOL®

coolant mixture to the fill neck until the coolant is within the cold fill region. With the intercooler system pressure cap off, start the engine and let it run for a couple of minutes. Then turn the engine off. By this time, the coolant level inside the fill neck may be lower. If the level drops where coolant is no longer within the cold fill region of the fill neck with the engine off, add more of the DEX-COOL® coolant mixture to the fill neck until the level is again visible in the cold fill region.

4. Then replace the pressure cap.

Be sure the pressure cap is hand-tight and fully seated.

1. Remove the intercooler system

pressure cap when the intercooler system hoses are 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 allows any pressure still left to be vented.

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. If the coolant is not at the proper level when the system cools down again, see your dealer/retailer.

Engine Overheating The vehicle has several indicators to warn of engine overheating. There are two engine hot messages that may be displayed in the Driver Information Center (DIC). See Driver Information Center (DIC) on page 4‑31 for more information. You may decide not to lift the hood when this warning appears, but instead get service help right away. See Roadside Service on page 12‑6 .

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, the fan(s) 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 because of being driven with no coolant, your 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. Just 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 your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.

If the temperature overheat gage 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 operating mode allows your vehicle to be driven to a safe place in an emergency. Should a hot engine condition exist, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, there is a loss in power and engine performance. Driving extended miles (km) and/or towing a trailer in the overheat protection mode should be avoided.

9-24

Vehicle Care

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: 1. Turn the air conditioning off. 2. Turn the heater on to the highest

3.

temperature and to the highest fan speed. Open the windows as necessary. In heavy traffic, let the engine idle in N (Neutral) while stopped. If it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) and let the engine idle.

Power Steering Fluid

See Engine Compartment Overview on page 9‑6 for the location of the power steering fluid reservoir. 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: 1. Turn the key off and let the

engine compartment cool down. 2. Wipe the cap and the top of the

reservoir clean.

3. Unscrew the cap and wipe the

dipstick with a clean rag.

4. Replace the cap and completely

tighten it.

5. Remove the cap again and look at the fluid level on the dipstick.

The level should be between the HOT and COLD marks. If necessary, add only enough fluid to bring the level up to the mark.

Vehicle Care

9-25

What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 10‑7 . Always use the proper fluid.

Washer Fluid

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

9-26

Vehicle Care

Adding Washer Fluid The Washer Fluid Low Add Fluid message will appear on the Driver Information Center (DIC) when the fluid level is low. See Driver Information Center (DIC) on page 4‑31 for more information.

Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 9‑6 for reservoir location.

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 on page 11‑2. 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.

Vehicle Care

9-27

Brake Fluid

The brake master cylinder reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview on page 9‑6 for the location of the reservoir. 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.

9-28

Vehicle Care

. 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.

{ 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 on page 4‑26.

What to Add Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants on page 10‑7. 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.

Battery The battery is in the trunk, behind the trim panel, on the passenger side of the vehicle. Refer to the replacement number shown on the original battery label when a new battery is needed.

{ DANGER

Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

After a power loss, such as disconnecting the battery or removing the maxi fuses in the power distribution fuse block, the following steps must be performed to calibrate the electronic throttle control. If this is not done, the engine will not run properly. 1. Turn the ignition to ON/RUN.

Do not start the engine.

2. Leave the ignition in ON/RUN for at least three minutes so that the electronic throttle control will cycle and re-learn its home position.

3. Turn the ignition to LOCK/OFF. 4. Start and run the engine for at

least 30 seconds.

. Be fully assembled and all other

work stopped while headlamp aiming is being performed. . Normally loaded with a full

tank of fuel and one person or 75 kg (160 lbs) sitting on the driver seat.

. Have all tires properly inflated. If your vehicle has a spare tire, ensure the spare tire is in its original location in the vehicle. Headlamp aiming is done with the vehicle's low-beam headlamps. The high-beam headlamps will be correctly aimed if the low-beam headlamps are aimed properly.

Headlamp Aiming The vehicle has a visual optical headlamp aiming system. The aim has been preset at the factory and should need no further adjustment. However, if the vehicle is damaged in a crash, the headlamp aim may be affected and adjustment may be necessary. If oncoming vehicles flash their high beams at you, this may also mean the vertical aim needs to be adjusted. It is recommended that the vehicle is taken to your dealer/retailer for service if the headlamps need to be re-aimed. It is possible however, to re-aim the headlamps as described. The vehicle should: . Be placed so the headlamps are 7.6 m (25 ft) from a light colored wall.

. Have all four tires on a level

surface which is level all the way to the wall.

To adjust the vertical aim: 1. Open the hood. See Hood on

page 9‑5 for more information.
