is approved to the dexos™ specification or an equivalent engine oil of the appropriate viscosity grade. Engine oils approved to the dexos™ specification will show the dexos™ symbol on the container. Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. If you are unsure whether your oil is approved to the dexos™ specification, ask your service provider.

Use of Substitute Engine Oils if dexos™ is unavailable: In the event that dexos™ approved engine oil is not available at an oil change or for maintaining proper oil level, you may use substitute engine oil displaying the API Starburst symbol and of SAE 5W-30 viscosity grade. Use of oils that do not meet the dexos™ specification, however, may result in reduced performance under certain circumstances.

Viscosity Grade SAE 5W-30 is the best viscosity grade for the vehicle. Do not use other viscosity oils such as SAE 10W‐30, 10W‐40, or 20W-50.

GMC Canyon Owner Manual - 2011

(−20°F), an SAE 0W-30 oil should be used. An 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, be sure to always select an oil that meets the required specification, dexos™. See “Specification” for more information. Engine Oil Additives/Engine Oil Flushes Do not add anything to the oil. The recommended oils with the dexos™ specification and displaying the dexos™ certification mark 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.

Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −29°C

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 OIL message comes on. See Engine Oil Messages on page 5‑26. 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 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 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 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. Press and release the stem

in the lower center of the instrument cluster until the OIL LIFE message is displayed.

3. Once the alternating OIL LIFE and RESET messages appear, press and hold the stem until several beeps sound. This confirms that the oil life system has been reset.

4. Turn the key to LOCK/OFF. If the CHANGE OIL message comes back on when the vehicle is started, the engine oil life system has not been reset. Repeat the procedure.

Automatic Transmission Fluid

When to Check and Change Automatic Transmission Fluid A good time to check the automatic transmission fluid level is when the engine oil is changed. Change the fluid and filter at the intervals listed in Scheduled Maintenance on page 11‑2, and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants on page 11‑6. How to Check Automatic Transmission Fluid Because this operation can be a little difficult, it may be decided to have this done at the dealer service department. If not taken to the dealer, be sure to follow all the instructions here, or a false reading on the dipstick could result.

Notice: Too much or too little fluid can damage the transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if checking the transmission fluid. Wait at least 30 minutes before checking the transmission fluid level if the vehicle has been driven: . When outside temperatures are

above 32°C (90°F).

. At high speed for quite a while. In heavy traffic — especially in hot weather.

. While pulling a trailer. To get the right reading, the fluid should be at normal operating temperature, which is 82°C to 93°C (180°F to 200°F).

Vehicle Care

10-15

Get the vehicle warmed up by driving about 24 km (15 mi) when outside temperatures are above 10°C (50°F). If it is colder than 10°C (50°F), drive the vehicle in 3 (Third) until the engine temperature gauge moves and then remains steady for 10 minutes. A cold fluid check can be made after the vehicle has been sitting for eight hours or more with the engine off, but this is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 10°C (50°F) or more. If it is colder than 10°C (50°F), the engine may have to idle longer. Should the fluid level be low during this cold check, check the fluid hot before adding fluid. Checking the fluid hot gives a more accurate reading of the fluid level.

Vehicle Care

Checking the Fluid Level To prepare the vehicle: 1. Park the vehicle on a level

place. Keep the engine running. 2. With the parking brake applied, place the shift lever in P (Park).

3. With foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in P (Park).

4. Let the engine run at idle for

three minutes or more.

Then, without shutting off the engine: 1. Flip the handle up and then

pull out the dipstick and wipe it with a clean rag or paper towel.

area, below the cross-hatched area, for a cold check or in the HOT or cross-hatched area for a hot check. Be sure to keep the dipstick pointed down to get an accurate reading. If the fluid level is in the acceptable range, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place.

4.

How to Add Automatic Transmission Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See Recommended Fluids and Lubricants on page 11‑6. Add fluid only after checking the transmission fluid while it is hot. A cold check is used only as a reference. If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check.

The automatic transmission dipstick handle with this symbol on it is located in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview on page 10‑6 for more information on location.

2. Push it back in all the way, wait three seconds, and pull it back out again.

3. Check both sides of the dipstick,

and read the lower level. The fluid level must be in the COLD

It does not take much fluid, generally less than 0.5 L (1 pt). Do not overfill. 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 on page 11‑6. . After adding fluid, recheck the fluid level as described under “How to Check Automatic Transmission Fluid,” earlier in this section.

. When the correct fluid level is

obtained, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place.

Manual Transmission Fluid

When to Check A good time to check the manual transmission fluid is when the engine oil is changed. However, the fluid in the manual transmission does not require changing. How to Check Because this operation can be a little difficult, it may be decided to have this done at the dealer service department. If not taken to the dealer, be sure to follow all the instructions here, or a false reading on the dipstick could result. Notice: Too much or too little fluid can damage the transmission. Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if checking the transmission fluid.

Vehicle Care

10-17

Check the fluid level only when the engine is off, the vehicle is parked on a level place and the transmission is cool enough to touch the transmission case. After this is done:

1. Remove the fill plug. 2. Check that the lubricant level

is up to the bottom of the fill plug hole.

GMC Canyon Owner Manual - 2011

3.

If the fluid level is good, install the plug and be sure it is fully seated. If the fluid level is low, add more fluid as described in the next steps.

How to Add Fluid Here is how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See Recommended Fluids and Lubricants on page 11‑6. 1. Remove the fill plug. 2. Add fluid at the fill plug hole.

Add only enough fluid to bring the fluid level up to the bottom of the fill plug hole. Install the fill plug. Be sure the plug is fully seated.

3.

Hydraulic Clutch The hydraulic clutch linkage in the vehicle is self-adjusting. The clutch master cylinder reservoir is filled with hydraulic clutch fluid.

The hydraulic clutch fluid reservoir cap has this symbol on it. See Engine Compartment Overview on page 10‑6 for reservoir location. It is not necessary to regularly check clutch fluid unless a leak in the system is suspected. 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

Refer to the Maintenance Schedule to determine how often to check the fluid level in the clutch master cylinder reservoir and for the proper fluid. See Recommended Fluids and Lubricants on page 11‑6. How to Check and Add Fluid The proper fluid should be added if the level does not reach the bottom of the diaphragm when it is in place in the reservoir. See the instructions on the reservoir 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.

GMC Canyon Owner Manual - 2011

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. See Recommended Fluids and Lubricants on page 11‑6 for more information. Never dispose of engine coolant by putting it in the trash, pouring it on the ground, into sewers, into streams or bodies of water.

Vehicle Care

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.

The coolant recovery tank cap has this symbol on it. It is located toward the rear of the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview on page 10‑6 for more information on location.

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 vehicle must be on a level surface. When the engine is cold, the coolant level should be at FULL COLD, or a little higher. When the engine is warm, the level could be above the FULL COLD level. When the engine is cold, the coolant level should be at least up to the FULL COLD mark. If it is not, there could be a leak in the cooling system.

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. When the coolant in the coolant recovery tank is at the FULL COLD mark, start the vehicle. If coolant is needed, add the proper DEX-COOL coolant mixture at the coolant recovery tank.

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

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

Vehicle Care

10-23

Turn the pressure cap slowly counterclockwise about one full turn. If a hiss is heard, wait for that to stop. A hiss means there is still some pressure left.

2. Keep turning the cap to

remove it.

3. Fill the radiator with the proper

DEX‐COOL coolant mixture, up to the base of the filler neck. See Engine Coolant on page 10‑21 for more information about the proper coolant mixture.

1. Remove the radiator pressure cap when the cooling system, including the upper radiator hose, is no longer hot.

until the upper radiator hose can be felt getting hot. Watch out for the engine cooling fan.

7. By this time, the coolant level inside the radiator filler neck might be lower. If the level is lower, add more of the proper DEX‐COOL coolant mixture through the filler neck until the level reaches the base of the filler neck.

8. Then replace the pressure cap.

At any time during this procedure if coolant begins to flow out of the filler neck, reinstall the pressure cap. 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 a coolant temperature gauge displayed on the instrument panel to warn if the engine is overheating. See Engine Coolant Temperature Gauge on page 5‑10. If the engine is too hot, the air conditioning might stop working. This is normal and helps cool the engine. If the decision is made not to lift the hood when the warning appears, but instead get service help right away. See Roadside Assistance Program (U.S. and Canada) on page 13‑8
or Roadside Assistance Program (Mexico) on page 13‑10.

GMC Canyon Owner Manual - 2011

Vehicle Care

10-25

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 and have the vehicle serviced. The engine cooling fan speed should increase when idle speed is doubled by pushing the accelerator pedal down. If it does not, the vehicle needs service. Turn off the engine. 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 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. See “Driving on Grades” under Trailer Towing on page 9‑64.

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.

Vehicle Care

3.

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.

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 slowly for about 10 minutes. Keep a safe vehicle distance from the vehicle in front. 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.

Engine Fan This vehicle has a clutched engine cooling fan. When the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the clutch is not engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing and/or high outside temperatures, the fan speed increases when the clutch engages. So you may hear an increase in fan noise. This is normal and should not be mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan will slow down when additional cooling is not required and the clutch disengages. This fan noise may also be heard when the engine is started. It will go away as the fan clutch disengages.

Power Steering Fluid

The power steering fluid reservoir is located near the front of the engine compartment, behind the radiator. See Engine Compartment Overview on page 10‑6 for reservoir location. When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless there is a leak suspected in the system or an unusual noise is heard. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

GMC Canyon Owner Manual - 2011

Black plate (27,1)

What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 11‑6. 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 on page 11‑6.

Vehicle Care

10-27

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.

How to Check 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. Then remove the cap again and

look at the fluid level on the dipstick.

The level should be between the ADD and FULL marks. If necessary, add only enough fluid to bring the level up to the proper range.

Vehicle Care

Adding Washer Fluid

Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 10‑6 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 windshield washer system and paint.

Brakes This vehicle has front disc brakes and rear drum 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 a crash. 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 12‑2.

GMC Canyon Owner Manual - 2011

Black plate (29,1)

Rear drum brakes do not have wear indicators, but if a rear brake rubbing noise is heard, have the rear brake linings inspected immediately. Rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. Drum brakes have an inspection hole to inspect lining wear during scheduled maintenance. When the front brake pads are replaced, have the rear brakes inspected, too. Brake linings should always 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 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

10-29

Brake Fluid

The brake master cylinder reservoir is filled with DOT 3 brake fluid. See Engine Compartment Overview on page 10‑6 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.

. 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.

GMC Canyon Owner Manual - 2011

Black plate (30,1)

10-30

Vehicle Care

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. See “Checking Brake Fluid” in this section.

Refer to the Maintenance Schedule to determine when to check the brake fluid. See Scheduled Maintenance on page 11‑2.

Checking Brake Fluid Check brake fluid by looking at the brake fluid reservoir. See Engine Compartment Overview on page 10‑6.

The fluid level should be above the PP mark. If it is not, have the brake hydraulic system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the PP mark but not over the MAX mark.

What to Add Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants on page 11‑6. 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.

Electrical System

Electrical System Overload The vehicle has fuses and circuit breakers to protect against an electrical system overload. When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems.

Windshield Wipers If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart. Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.

Fuses and circuit breakers protect the following in the vehicle: . Headlamp Wiring . Windshield Wiper Motor . Power Windows and Other

Power Accessories

Replace a bad fuse with a new one of the identical size and rating. If there is a problem on the road and a fuse needs to be replaced, the same amperage fuse can be borrowed. Choose some feature of the vehicle that is not needed to use and replace it as soon as possible. Headlamp Wiring An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off.

GMC Canyon Owner Manual - 2011

Black plate (43,1)

Fuses and Circuit Breakers The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and do not have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of the vehicle that you can get along without — like the radio or cigarette lighter — and use its fuse, if it is the correct amperage. Replace it as soon as you can.
