Towing a Trailer


{ CAUTION


The driver can lose control when pulling a trailer if the correct equipment is not used or the vehicle is not driven properly. For example, if the trailer is too heavy, the brakes may not work well — or even at all. The driver and passengers could be seriously injured. The vehicle may also be damaged; the resulting repairs would not be covered by the vehicle warranty. Pull a trailer only if all the steps in this section have been followed. Ask your dealer/retailer for advice and information about towing a trailer with the vehicle.


To identify the trailering capacity of the vehicle, read the information in “Weight of the Trailer” that appears later in this section.


Trailering is different than just driving the vehicle by itself. Trailering means changes in handling, acceleration, braking, durability and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. The following information has many time-tested, important trailering tips and safety rules. Many of these are important for the safety of the driver and the passengers. So please read this section carefully before pulling a trailer. Load-pulling components such as the engine, transmission, rear axle, wheel assemblies and tires are forced to work harder against the drag of the added weight. The engine is required to operate at relatively higher speeds and under greater loads, generating extra heat. What’s more, the trailer adds considerably to wind resistance, increasing the pulling requirements.


Pulling A Trailer Here are some important points:


There are many different laws, including speed limit restrictions, having to do with trailering. Make sure the rig will be legal, not only where you live but also where you will be driving. A good source for this information can be state or provincial police.


(cid:129) Consider using a sway control.


See “Hitches” later in this section.


(cid:129) Do not tow a trailer at all during the first 500 miles (800 km) the new vehicle is driven. The engine, axle or other parts could be damaged. Then, during the first 500 miles (800 km) that a trailer is towed, do not drive over 50 mph (80 km/h) and do not make starts at full throttle. This helps the engine and other parts of the vehicle wear in at the heavier loads.


(cid:129) (cid:129) (cid:129) Obey speed limit restrictions


when towing a trailer. The vehicles can tow in D (Drive). Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions. See “Tow/Haul Mode” later in this section. The vehicle is designed primarily as a passenger and load carrying vehicle. If a trailer is towed, the vehicle will require more frequent maintenance due to the additional load.

Three important considerations have to do with weight:


The weight of the trailer. The weight of the trailer tongue. (cid:129) And the weight on the vehicle’s


tires


Weight of the Trailer How heavy can a trailer safely be? It depends on how the rig is used. For example, speed, altitude, road grades, outside temperature and how much the vehicle is used to pull a trailer are all important. It can depend on any special equipment on the vehicle, and the amount of


tongue weight the vehicle can carry. See “Weight of the Trailer Tongue” later in this section for more information. Maximum trailer weight is calculated assuming only the driver is in the tow vehicle and it has all the required trailering equipment. The weight of additional optional equipment, passengers and cargo in the tow vehicle must be subtracted from the maximum trailer weight. Use the following chart to determine how much the vehicle can weigh, based upon the vehicle model and options.

Ask your dealer/retailer for our trailering information or advice, or write us at our Customer Assistance Offices. See Customer Assistance Offices on page 7-4 for more information.


Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total gross weight of the vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo carried in it, and the people who will be riding in the vehicle. If there are a lot of options, equipment, passengers or cargo in the vehicle, it will reduce the tongue weight the vehicle can carry, which will also reduce the trailer weight the vehicle can tow. If towing a trailer, the tongue load must be added to the GVW because the vehicle will be carrying that weight, too. See Loading the Vehicle on page 4-16 for more information about the vehicle’s maximum load capacity.


weight may reduce the trailering capacity more than the total of the additional weight. Consider the following example: A vehicle model base weight is 5,500 lbs (2 495 kg); 2,800 lbs (1 270 kg) at the front axle and 2,700 lbs (1 225 kg) at the rear axle. It has a GVWR of 7,200 lbs (3 266 kg), a RGAWR of 4,000 lbs (1 814 kg) and a GCWR (Gross Combination Weight Rating) of 14,000 lbs (6 350 kg). The trailer rating should be:


Expect tongue weight to be at least 10 percent of trailer weight (850 lbs (386 kg)) and because the weight is applied well behind the rear axle, the effect on the rear axle is greater than just the weight itself, as much as 1.5 times as much. The weight at


If a weight-carrying hitch or a weight-distributing hitch is being used, the trailer tongue (A) should weigh 10-15 percent of the total loaded trailer weight (B). After loading the trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren’t, adjustments might be made by moving some items around in the trailer. Trailering may also be limited by the vehicle’s ability to carry tongue weight. Tongue weight cannot cause the vehicle to exceed the GVWR (Gross Vehicle Weight Rating) or the RGAWR (Rear Gross Axle Weight Rating). The effect of additional


the rear axle could be 850 lbs (386 kg) X 1.5 = 1,275 lbs (578 kg). Since the rear axle already weighs 2,700 lbs (1 225 kg), adding 1,275 lbs (578 kg) brings the total to 3,975 lbs (1 803 kg). This is very close to, but within the limit for RGAWR as well. The vehicle is set to trailer up to 8,500 lbs (3 856 kg). If the vehicle has many options and there is a front seat passenger and two rear seat passengers with some luggage and gear in the vehicle as well. 300 lbs (136 kg) could be added to the front axle weight and 400 lbs (181 kg) to the rear axle weight. The vehicle now weighs:


Weight is still below 7,200 lbs (3 266 kg) and you might think 700
additional pounds (318 kg) should be subtracted from the trailering capacity to stay within GCWR limits.


The maximum trailer would only be 7,800 lbs (3 538 kg). You may go further and think the tongue weight should be limited to less than 1,000 lbs (454 kg) to avoid exceeding GVWR. But the effect on the rear axle must still be considered. Because the rear axle now weighs 3,100 lbs (1 406 kg), 900 lbs (408 kg) can be put on the rear axle without exceeding RGAWR. The effect of tongue weight is about 1.5 times the actual weight. Dividing the 900 lbs (408 kg) by 1.5 leaves only 600 lbs (272 kg) of tongue weight that can be handled. Since tongue weight is usually at least 10 percent of total loaded trailer weight, expect that the largest trailer the vehicle can properly handle is 6,000 lbs (2 721 kg). It is important that the vehicle does not exceed any of its ratings — GCWR, GVWR, RGAWR, Maximum Trailer Rating or Tongue Weight. The only way to be sure it is not exceeding any of these ratings is to weigh the vehicle and trailer.

Total Weight on the Vehicle’s Tires Be sure the vehicle’s tires are inflated to the upper limit for cold tires. These numbers can be found on the Certification/Tire label. See Loading the Vehicle on page 4-16. Make sure not to go over the GVW limit for the vehicle, including the weight of the trailer tongue.


Hitches It is important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why the right hitch is needed. Here are some rules to follow:


The rear bumper on the vehicle is not intended for hitches. Do not attach rental hitches or other bumper-type hitches to it. Use only a frame-mounted hitch that does not attach to the bumper.


(cid:129) 4-28


Driving Your Vehicle


(cid:129) Will any holes be made in the body of the vehicle when the trailer hitch is installed? If there are, then be sure to seal the holes later when the hitch is removed. If the holes are not sealed, dirt, water, and deadly carbon monoxide (CO) from the exhaust can get into the vehicle. See Engine Exhaust on page 2-30.


Safety Chains Always attach chains between the vehicle and the trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer’s recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so the rig can turn. Never allow safety chains to drag on the ground.


Trailer Brakes A loaded trailer that weighs more than 1,000 lbs (450 kg) needs to have its own brake system that is adequate for the weight of the trailer. Be sure to read and follow the instructions for the trailer brakes so they are installed, adjusted and maintained properly. Because the vehicle has antilock brakes, do not try to tap into the vehicle’s hydraulic brake system. If you do, both brake systems will not work well, or at all.


Driving with a Trailer Towing a trailer requires a certain amount of experience. Get to know the rig before setting out for the open road. Get acquainted with the feel of handling and braking with the added weight of the trailer. And always keep in mind that the vehicle you are driving is now longer and not as responsive as the vehicle is by itself.


Before starting, check all trailer hitch parts and attachments, safety chains, electrical connectors, lamps, tires and mirror adjustments. If the trailer has electric brakes, start the vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This checks the electrical connection at the same time. During the trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes are still working.


Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving the vehicle without a trailer. This can help to avoid situations that require heavy braking and sudden turns.


Passing More passing distance is needed when towing a trailer. Because the rig is longer, it is necessary to go much farther beyond the passed vehicle before returning to the lane.


Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you.


Making Turns Notice: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. The vehicle could be damaged. Avoid making very sharp turns while trailering. When turning with a trailer, make wider turns than normal. Do this so the trailer won’t strike soft shoulders,


curbs, road signs, trees or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. Turn Signals When Towing a Trailer The arrows on the instrument panel flash whenever signaling a turn or lane change. Properly hooked up, the trailer lamps also flash, telling other drivers the vehicle is turning, changing lanes or stopping. When towing a trailer, the arrows on the instrument panel flash for turns even if the bulbs on the trailer are burned out. For this reason you may think other drivers are seeing the signal when they are not. It is important to check occasionally to be sure the trailer bulbs are still working.


Driving on Grades Because of the added load of the trailer, the vehicle’s engine may overheat on hot days, when going up a long or steep grade with a trailer. If the engine coolant


Driving Your Vehicle

temperature gage indicates overheating, turn off the air conditioning to reduce engine load, pull off the road and stop in a safe spot. Let the engine run while parked, preferably on level ground, with the transmission in P (Park) for a few minutes before turning the engine off. Reduce speed and shift to a lower gear before starting down a long or steep downgrade. If the transmission is not shifted down, the brakes might have to be used so much that they would get hot and no longer work well. On a long uphill grade, shift down and reduce the vehicle speed to around 55 mph (88 km/h) to reduce the possibility of the engine and the transmission overheating.

Driving Your Vehicle


Tow/Haul Mode Tow/Haul is a feature that assists when pulling a heavy trailer or a large or heavy load. The purpose of the Tow/Haul mode is to: (cid:129) Reduce the frequency and improve the predictability of transmission shifts when pulling a heavy trailer or a large or heavy load.


(cid:129) Provide the same solid shift feel when pulling a heavy trailer or a large or heavy load as when the vehicle is unloaded. Improve control of vehicle speed while requiring less throttle pedal activity when pulling a heavy trailer or a large or heavy load. Increase the charging system voltage to assist in recharging a battery installed in a trailer.


Press this button located on the console to turn on and turn off the Tow/Haul mode. The Tow/Haul light on the instrument panel will come on to indicate that Tow/Haul mode has been selected. Tow/Haul may be turned off by pressing the button again, at which time the indicator light on the instrument panel will turn off. The vehicle will automatically turn off Tow/Haul every time it is started. Tow/Haul is designed to be most effective when the vehicle and trailer combined weight is at least 75 percent of the vehicle’s Gross Combined Weight Rating (GCWR). See Weight of the Trailer earlier in this section.


Tow/Haul is most useful under the following driving conditions: (cid:129) When pulling a heavy trailer or a


large or heavy load through rolling terrain.


(cid:129) When pulling a heavy trailer or a


large or heavy load in stop and go traffic.


(cid:129) When pulling a heavy trailer or a


large or heavy load in busy parking lots where improved low speed control of the vehicle is desired.


Operating the vehicle in Tow/Haul when lightly loaded or with no trailer at all will not cause damage. However, there is no benefit to the selection of Tow/Haul when the vehicle is unloaded. Such a selection when unloaded may result in unpleasant engine and transmission driving characteristics and reduced fuel economy. Tow/Haul is recommended only when pulling a heavy trailer or a large or heavy load.


(cid:129) (cid:129) Parking on Hills


{ CAUTION


Parking the vehicle on a hill with the trailer attached can be dangerous. If something goes wrong, the rig could start to move. People can be injured, and both the vehicle and the trailer can be damaged. When possible, always park the rig on a flat surface.


If parking the rig on a hill: 1. Press the brake pedal, but do


not shift into P (Park) yet. Turn the wheels into the curb if facing downhill or into traffic if facing uphill.


2. Have someone place chocks


under the trailer wheels.


3. When the wheel chocks are in place, release the brake pedal until the chocks absorb the load.


4. Reapply the brake pedal. Then


apply the parking brake and shift the transmission into P (Park).


5. Release the brake pedal. Leaving After Parking on a Hill 1. Apply and hold the brake pedal


while you:


start the engine, shift into a gear, and release the parking brake.


2. Let up on the brake pedal. 3. Drive slowly until the trailer is


clear of the chocks.


4. Stop and have someone pick up


and store the chocks.


Maintenance When Trailer Towing The vehicle needs service more often when pulling a trailer. See Scheduled Maintenance on page 6-3 for more information.

Things that are especially important in trailer operation are automatic transmission fluid, engine oil, axle lubricant, belts, cooling system and brake system. It is a good idea to inspect these before and during the trip. Check periodically to see that all hitch nuts and bolts are tight.


Trailer Wiring Harness The vehicle is equipped with the following wiring harness for towing a trailer.


Basic Trailer Wiring The trailer wiring harness, with a seven-pin connector, is located at the rear of the vehicle and is tied to the vehicle’s frame. The harness connector can be plugged into a seven-pin universal heavy-duty trailer connector available through your dealer/retailer.


(cid:129) (cid:129) (cid:129) 4-32

They should be connected by your dealer/retailer or a qualified service center. If the back-up lamp circuit is not functional, contact your dealer/ retailer.


If a remote (non-vehicle) battery is being charged, press the Tow/Haul mode switch located on the center console near the climate controls. This will boost the vehicle system voltage and properly charge the battery. If the trailer is too light for Tow/Haul mode, turn on the headlamps (Non-HID only) as a second way to boost the vehicle system and charge the battery. Electric Trailer Brake Control Wiring Provisions These wiring provisions for an electric trailer brake controller are included with the vehicle as part of the trailer wiring package. The instrument panel contains blunt cut wires behind the steering column for the electric trailer brake controller.


The harness contains the following wires: (cid:129) Red/Black: Power Supply (cid:129) White: Brake Switch Signal (cid:129) Gray: Illumination (cid:129) Dark Blue: Trailer Brake Signal (cid:129) Black: Ground The electric trailer brake controller should be installed by your dealer/ retailer or a qualified service center. Engine Cooling When Trailer Towing The cooling system may temporarily overheat during severe operating conditions. See Engine Overheating on page 5-22.

Accessories and Modifications When non-dealer/non-retailer accessories are added to the vehicle, they can affect vehicle performance and safety, including such things as airbags, braking, stability, ride and handling, emissions systems, aerodynamics, durability, and electronic systems like antilock brakes, traction control, and stability control. Some of these accessories could even cause malfunction or damage not covered by the vehicle warranty. Damage to vehicle components resulting from the installation or use of non-GM certified parts, including control module modifications, are not covered under the terms of the vehicle warranty and may affect remaining warranty coverage for affected parts. GM Accessories are designed to complement and function with other systems on the vehicle. Your GM dealer/retailer can accessorize the


vehicle using genuine GM Accessories. When you go to your GM dealer/retailer and ask for GM Accessories, you will know that GM-trained and supported service technicians will perform the work using genuine GM Accessories. Also, see Adding Equipment to Your Airbag-Equipped Vehicle on page 1-58.


California Proposition 65
Warning Most motor vehicles, including this one, contain and/or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Engine exhaust, many parts and systems (including some inside the vehicle), many fluids, and some component wear by-products contain and/or emit these chemicals.

California Perchlorate Materials Requirements Certain types of automotive applications, such as airbag initiators, seat belt pretensioners, and lithium batteries contained in remote keyless transmitters, may contain perchlorate materials. Special handling may be necessary. For additional information, see www.dtsc.ca.gov/hazardouswaste/ perchlorate.


Doing Your Own Service Work


{ CAUTION You can be injured and the vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it.


(cid:129) Be sure you have sufficient knowledge, experience, the proper replacement parts, and tools before attempting any vehicle maintenance task. (cid:129) Be sure to use the proper


nuts, bolts, and other fasteners. English and metric fasteners can be easily confused. If the wrong fasteners are used, parts can later break or fall off. You could be hurt.


If doing some of your own service work, use the proper service manual. It tells you much more about how to service the vehicle


than this manual can. To order the proper service manual, see Service Publications Ordering Information on page 7-13. This vehicle has an airbag system. Before attempting to do your own service work, see Servicing Your Airbag-Equipped Vehicle on page 1-57. Keep a record with all parts receipts and list the mileage and the date of any service work performed. See Maintenance Record on page 6-13.


Adding Equipment to the Outside of the Vehicle Things added to the outside of the vehicle can affect the airflow around it. This can cause wind noise and can affect fuel economy and windshield washer performance. Check with your dealer/retailer before adding equipment to the outside of the vehicle.


Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend the use of gasoline advertised as TOP TIER Detergent Gasoline.


Gasoline Octane Use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, you might notice an audible knocking noise when you drive, commonly referred to as spark knock. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, the engine needs service.


Service and Appearance Care

Gasoline Specifications At a minimum, gasoline should meet ASTM specification D 4814 in the United States or CAN/CGSB-3.5 or 3.511 in Canada. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See Additives on page 5-5 for additional information.


California Fuel If the vehicle is certified to meet California Emissions Standards, it is designed to operate on fuels that meet California specifications. See the underhood emission control label. If this fuel is not available in states adopting California emissions standards, the vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance might be affected. The malfunction indicator lamp could turn on and the vehicle


might fail a smog-check test. See Malfunction Indicator Lamp on page 3-37. If this occurs, return to your authorized dealer/retailer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs might not be covered by the vehicle warranty.


Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that help prevent engine and fuel system deposits from forming, allowing the emission control system to work properly. In most cases, you should not have to add anything to the fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. To help keep fuel injectors and intake valves clean, or if the vehicle experiences problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline.

Service and Appearance Care


For customers who do not use TOP TIER Detergent Gasoline regularly, one bottle of GM Fuel System Treatment PLUS, added to the fuel tank at every engine oil change, can help clean deposits from fuel injectors and intake valves. GM Fuel System Treatment PLUS is the only gasoline additive recommended by General Motors. Also, your dealer/retailer has additives that will help correct and prevent most deposit-related problems. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines might be available in your area. We recommend that you use these gasolines, if they comply with the specifications described earlier. However, E85 (85% ethanol) and other fuels containing more than 10% ethanol must not be used in vehicles that were not designed for those fuels.


Notice: This vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under the vehicle warranty. Some gasolines that are not reformulated for low emissions can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. We recommend against the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system could be affected. The malfunction indicator lamp might turn on. If this occurs, return to your dealer/retailer for service.


Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel might be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving.


Filling the Tank


{ CAUTION


Fuel vapor burns violently and a fuel fire can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off the engine when you are refueling. Do not smoke if you are near fuel or refueling the vehicle. Do not use cellular phones. Keep sparks, flames, and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling the vehicle. This is against the law in some places. Do not re-enter the vehicle while pumping fuel. Keep children away from the fuel pump; never let children pump fuel.


The tethered fuel cap is located behind a hinged fuel door on the driver side of the vehicle.

To open the fuel door, push the rearward center edge in and release and it will open.


To remove the fuel cap, turn it slowly counterclockwise. The fuel cap has a spring in it; if the cap is released too soon, it will spring back to the right. While refueling, hang the tethered fuel cap from the hook on the fuel door.


{ CAUTION


Fuel can spray out on you if you open the fuel cap too quickly. If you spill fuel and then something ignites it, you could be badly burned. This spray can happen if the tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any hiss noise to stop. Then unscrew the cap all the way.


Be careful not to spill fuel. Do not top off or overfill the tank and wait a few seconds after you have finished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Washing Your Vehicle on page 5-83.

Service and Appearance Care


When replacing the fuel cap, turn it clockwise until it clicks. Make sure the cap is fully installed. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See Malfunction Indicator Lamp on page 3-37. If the vehicle has a Driver Information Center (DIC), the TIGHTEN GAS CAP message displays if the fuel cap is not properly installed.


{ CAUTION


If a fire starts while you are refueling, do not remove the nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately.


If you need a new fuel


Notice: cap, be sure to get the right type. Your dealer/ retailer can get one for you. If you get the wrong type, it might not fit properly. This can cause the malfunction indicator lamp to light and can damage the fuel tank and emissions system. See Malfunction Indicator Lamp on page 3-37.


Filling a Portable Fuel Container


{ CAUTION


Never fill a portable fuel container while it is in the vehicle. Static electricity discharge from the container can ignite the fuel vapor. You can be badly burned

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. See Engine Compartment Overview on page 5-10 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 quart/liter of the recommended oil. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 5-94. 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 5-10 for the location of the engine oil fill cap. 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:


(cid:129) GM6094M


Use only an oil that meets GM Standard GM6094M.


Service and Appearance Care


5-13


(cid:129) 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.


(cid:129) 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. See “What Kind of Engine Oil to Use” for more information. Engine Oil Additives / Engine Oil Flushes Do not add anything to the oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all that is needed for good performance and engine protection.

Service and Appearance Care


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: 1. Turn the ignition to ON/RUN,


with the engine off.


2. Press the vehicle information


button until OIL LIFE REMAINING displays.


3. Press and hold the set/reset


button until 100% is displayed. Three chimes sound and the CHANGE ENGINE OIL SOON message goes off.


4. 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.


Engine Air Cleaner/Filter 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 50,000 mile (80 000 km) interval. See Scheduled Maintenance on page 6-3 for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change. See Engine Compartment Overview on page 5-10 for the location of the engine air cleaner/filter. 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 (away from vehicle) 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. Loosen the screws that hold the


cover on.


2. Disconnect the electrical


connector.


3. Lift off the cover. 4. Remove the engine air


cleaner/filter element and any loose debris that may be found in the air cleaner base.


5. Inspect or replace the air filter


element.

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. Change the fluid at the intervals listed in Additional Required Services on page 6-5, and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants on page 6-11.


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 6-11. 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.


6. Reverse Steps 1 through 3 to


reinstall the cover and reconnect the electrical connector. { CAUTION


Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air; it helps to stop flames if the engine backfires. If it is not there and the engine backfires, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/filter off.


If the air cleaner/filter is


Notice: off, a backfire can cause a damaging engine fire. And, dirt can easily get into the engine, which will damage it. Always have the air cleaner/filter in place when you are driving.

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 30,000 miles (50 000 km) 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.


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


{ CAUTION


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.


{ CAUTION


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.


5-18


Service and Appearance Care


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 150,000 miles (240 000 km), 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 5-22.


What to Use


{ CAUTION


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: (cid:129) Gives freezing protection down to


−34°F (−37°C), outside temperature.


(cid:129) Gives boiling protection up to


265°F (129°C), engine temperature.


(cid:129) Protects against rust and


corrosion.


(cid:129) Will not damage aluminum parts. (cid:129) Helps keep the proper engine


temperature.


If an improper coolant


Notice: 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.

If extra inhibitors and/or


Notice: 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 6-11 for more information.


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. See Engine Coolant on page 5-18 for more information.


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


{ CAUTION


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


{ CAUTION


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.


{ CAUTION


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.


1. Detach fasteners and lift off


the panel that covers the radiator cap.


2. 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.

3. Keep turning the pressure cap


slowly and remove it.


4. Fill the radiator to the base of the


filler neck with the proper DEX-COOL coolant mixture.


5. When coolant begins to flow out


of the filler neck, reinstall the pressure cap. Be sure to secure it tightly.


6. Fill the coolant recovery tank to


the FULL COLD mark.


7. Reinstall the cap on the coolant


recovery tank but leave the radiator pressure cap off.


8. 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).

Service and Appearance Care


9. 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.


If the pressure cap is not


Notice: 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 gage on the instrument panel cluster. See Engine Coolant Temperature Gage on page 3-36. The vehicle may also display an ENGINE OVERHEATED IDLE ENGINE and ENGINE OVERHEATED STOP ENGINE message in the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-50. You may decide not to lift the hood when this warning appears, but instead get service help right away. See Roadside Assistance Program on page 7-6.


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, 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: while driving with no coolant, the vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty. See Overheated Engine Protection Operating Mode on page 5-24 for information on driving to a safe place in an emergency.

If Steam Is Coming From The Engine Compartment { CAUTION


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 vehicles 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. See Overheated Engine Protection Operating Mode on page 5-24 for information on driving to a safe place in an emergency.


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: (cid:129) Climbs a long hill on a hot day. (cid:129) 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


temperature and to the highest fan speed. Open the windows as necessary.


3. 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 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.
