Brakes
Antilock Brake System (ABS) This vehicle has the Antilock Brake System (ABS), an advanced electronic braking system that helps prevent a braking skid. When the engine is started and the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise might be heard while this test is going on, and it might even be noticed that the brake pedal moves a little. This is normal.
Driving and Operating
9-43
If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5‑16. If driving safely on a wet road and it becomes necessary to slam on the brakes and continue braking to avoid a sudden obstacle, a computer senses that the wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel. ABS can change the brake pressure to each wheel, as required, faster than any driver could. This can help the driver steer around the obstacle while braking hard.
Shifting Out of Neutral After towing the vehicle, you will have to shift out of N (Neutral) in order to drive. To shift out of N (Neutral), do the following: 1. Set the parking brake and apply
the regular brake pedal.
2. Start a vehicle with an automatic
transmission in P (Park). Use 1 (First) for vehicles with a manual transmission.
3. Shift the transmission to N (Neutral), or press the clutch pedal for vehicles with a manual transmission.
4. Press the button for the desired
transfer case shift position (Two-Wheel High, Four-Wheel High, or Four-Wheel Low). 5. After the transfer case has
shifted out of N (Neutral), the indicator light will go out.
6. Release the parking brake. 7. Shift the transmission to the
desired position.

Driving and Operating
As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, there will not be enough time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even with ABS. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You might hear the ABS pump or motor operating and feel the brake pedal pulsate, but this is normal.
Braking in Emergencies ABS allows the driver to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking.
Parking Brake
To set the parking brake, hold the brake pedal down, then push the parking brake pedal down to its fully-applied position. A chime will activate and the brake warning light, located on the instrument panel, will flash when the parking brake is applied and the vehicle is moving at least 5 km/h (3 mph) for at least three seconds. The chime will deactivate and the light will turn off when the parking brake is set and the vehicle is moving below 5 km/h (3 mph). See Brake System Warning Light on page 5‑15.
The parking brake pedal is located to the left of the brake pedal, near the driver door.
Chevrolet Colorado Owner Manual - 2011
Black plate (45,1)
If the ignition is on when the parking brake is released, the brake system warning light will go off. Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and are parking on any hill, see Driving Characteristics and Towing Tips on page 9‑56.
Driving and Operating

Brake Assist This vehicle has a brake assist feature designed to assist the driver in stopping or decreasing vehicle speed in emergency driving conditions. This feature uses the stability system hydraulic brake control module to supplement the power brake system under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stop or slow down the vehicle. The stability system hydraulic brake control module increases brake pressure at each corner of the vehicle until the ABS activates. Minor brake pedal pulsation or pedal movement during this time is normal and the driver should continue to apply the brake pedal as the driving situation dictates. The brake assist feature will automatically disengage when the brake pedal is released or brake pedal pressure is quickly decreased.
To release the parking brake, hold the regular brake pedal down. Pull the bottom edge of the lever, located above the parking brake pedal, with the parking brake symbol, directly rearward to release the parking brake.

Ride Control Systems
Traction Control System (TCS) The Traction Control System (TCS) is part of StabiliTrak. TCS limits wheel slip which is especially useful in slippery road conditions. The system operates only if it senses that any of the wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to limit wheel spin and also reduces engine power. The system may be heard or felt while it is working. This is normal and does not mean there is a problem with the vehicle. Notice: If the wheel(s) of one axle is allowed to spin excessively while the StabiliTrak®, ABS, brake warning lights, and any relevant DIC messages are displayed, the transfer case could be damaged. The repairs would not be covered by the vehicle warranty. Reduce
engine power and do not spin the wheel(s) excessively while these lights and messages are displayed. TCS can operate on dry roads under some conditions. When this happens, the system may be heard working or a reduction in acceleration may be noticed. This is normal and does not mean there is a problem with the vehicle. Examples of these conditions include hard acceleration in a turn, an abrupt upshift or downshift of the transmission or driving on rough roads. If cruise control is being used when TCS begins to limit wheel spin, the cruise control automatically disengages. The cruise control can be re-engaged when road conditions allow. See Cruise Control on page 9‑49. The message TRACTION FAULT appears in the Driver Information Center (DIC) when a TCS or Antilock Brake System (ABS)
problem has been detected and the vehicle needs service. When this message is on, the system will not limit wheel spin. Adjust your driving accordingly. See Ride Control System Messages on page 5‑25.
The StabiliTrak/TCS light will flash on the instrument panel cluster when the TCS system or StabiliTrak is both on and activated.
The StabiliTrak/TCS button is located on the instrument panel.

To turn off TCS, press and release the StabiliTrak/TCS button. The StabiliTrak/TCS light comes on in the instrument panel cluster, and TRAC OFF comes on the DIC. To turn TCS back on, press and release the StabiliTrak/TCS button. Adding non-dealer/non-retailer accessories can affect the vehicle's performance. See Accessories and Modifications on page 10‑4.
StabiliTrak® System The vehicle has an electronic stability control system called StabiliTrak. It is an advanced computer controlled system that assists the driver with directional control of the vehicle in difficult driving conditions. StabiliTrak activates when the computer senses a discrepancy between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively
applies braking pressure at any one of the vehicle's brakes to assist the driver with keeping the vehicle on the intended path. When the vehicle is started and begins to move, the system performs several diagnostic checks to insure there are no problems. The system may be heard or felt while it is working. This is normal and does not mean there is a problem with the vehicle. The system should initialize before the vehicle reaches 32 km/h (20 mph). In some cases, it may take approximately two miles of driving before the system initializes. If cruise control is being used when StabiliTrak activates, the cruise control automatically disengages. The cruise control can be re-engaged when road conditions allow. See Cruise Control on page 9‑49.
If there is a problem detected with
StabiliTrak, a SERVICE STAB SYS
message displays on the Driver
Information Center (DIC). See Ride
Control System Messages on
page 5‑25 for more information.
When this message is displayed,
the system is not working. Adjust
your driving accordingly.
StabiliTrak and Traction Control

and the systems are reset with
each ignition cycle. However,
when the transfer case is placed in
Four-Wheel-Low mode, StabiliTrak
is automatically disabled. See

necessary to “rock” the vehicle to attempt to free it. If traction control is turned off, only the brake-traction control portion of traction control will work. The engine speed management will be disabled. In this mode, engine power is not reduced automatically and the drive wheels can spin more freely. This can cause the brake-traction control to activate constantly. See If the Vehicle is Stuck on page 9‑19.
The StabiliTrak/TCS light will flash on the instrument panel cluster when the TCS system or StabiliTrak is both on and activated.
When the TCS or StabiliTrak system is turned off, the StabiliTrak/TCS light and the appropriate TRAC OFF or STAB SYS OFF message will be displayed on the DIC. The vehicle will still have brake-traction control when TCS or StabiliTrak is off, but will not be able to use the engine speed management system. The StabiliTrak/TCS light flashes when either system is actively working. See Traction Control System (TCS) on page 9‑46 for more information.
Limited-Slip Rear Axle Vehicles with a limited-slip rear axle can give more traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when traction is low, this feature allows the drive wheel with the most traction to move the vehicle.
The StabiliTrak/TCS button is located on the instrument panel. To turn off TCS, press and release the StabiliTrak/TCS button. The StabiliTrak/TCS light comes on in the instrument panel cluster, and TRAC OFF comes on the DIC. To turn TCS back on, press and release the StabiliTrak/TCS button. To turn off TCS and StabiliTrak, press and hold the StabiliTrak/TCS button until the TRAC OFF and STAB SYS OFF messages come on the DIC and the StabiliTrak/TCS light comes on the instrument panel.

Cruise Control With cruise control, a speed of about 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 40 km/h (25 mph). If the brakes are applied, the cruise control shuts off.
{ WARNING
Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use the cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads.
If the vehicle's StabiliTrak® /Traction Control System (TCS) begins to limit wheel spin while the cruise control is on, the cruise control automatically disengages. See StabiliTrak® System on page 9‑47 or Traction Control System (TCS) on page 9‑46. When road conditions allow you to safely use it again, the cruise control can be turned back on.

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. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com.
you might have to step on the accelerator pedal to maintain the vehicle speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle speed down. When the brakes are applied the cruise control is disengaged.
Ending Cruise Control There are two ways to end cruise control:
To disengage cruise control; step lightly on the brake pedal or lightly tap or press the clutch, for manual transmissions. To turn off the cruise control, move the cruise control lever to 9 .
Erasing Speed Memory The cruise control set speed is erased from memory by moving the cruise control lever to 9 or if the vehicle is turned off.
Recommended Fuel Use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, an audible knocking noise, commonly referred to as spark knock, might be heard when driving. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service.

Gasoline Specifications
(U.S. and Canada Only)
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 Fuel Additives
on page 9‑53 for additional
information.
California Fuel Requirements 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 5‑12. If this occurs, return to your authorized dealer 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.
Fuels in Foreign Countries 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.
Chevrolet Colorado Owner Manual - 2011

Fuel 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, nothing should have to be added 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 and avoid problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by the auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com.

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. It is available at your dealer. 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 spark plug life and affect emission control system performance. The malfunction indicator lamp might turn on. If this occurs, return to your dealer for service.

Filling the Tank
{ WARNING
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 fuel pump island. Turn off the engine when refueling. Do not smoke near fuel or when 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 remove the fuel cap, turn it slowly counterclockwise. While refueling, hang the tethered fuel cap from the hook on the fuel door.
{ WARNING
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 Exterior Care on page 10‑93. When replacing the fuel cap, turn it clockwise until it clicks. Make sure the cap is fully installed.

Towing
General Towing Information Only use towing equipment that has been designed for the vehicle. Contact your dealer or trailering dealer for assistance with preparing the vehicle for towing a trailer. See the following trailer towing information in this section:
For information on driving while towing a trailer, see “Driving Characteristics and Towing Tips.” For maximum vehicle and trailer weights, see “Trailer Towing.” For information on equipment to tow a trailer, see “Towing Equipment.”
For information on towing a disabled vehicle, see Towing the Vehicle on page 10‑87. For information on towing the vehicle behind another
vehicle such as a motor home, see Recreational Vehicle Towing on page 10‑88.
Driving Characteristics and Towing Tips
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.
. Consider using a sway control.
See “Hitches” in Towing Equipment on page 9‑66.
. Do not tow a trailer at all during the first 800 km (500 miles) the new vehicle is driven. The engine, axle or other parts could be damaged.
Then, during the first 800 km (500 miles) that a trailer is towed, do not drive over 80 km/h (50 mph) and do not make starts at full throttle. This helps the engine and other parts of the vehicle wear in at the heavier loads.
. Vehicles with automatic transmissions can tow in D (Drive), but you may want to shift to a lower gear selection if the transmission shifts too often (e.g., under heavy loads and/or hilly conditions). If the vehicle has a manual transmission it is better not to use the highest gear.
Three important considerations have to do with weight:
The weight of the trailer The weight of the trailer tongue The weight on the vehicle's tires

Driving with a Trailer
{ WARNING
When towing a trailer, exhaust gases may collect at the rear of the vehicle and enter if the liftgate, trunk/hatch, or rear-most window is open. Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. To maximize safety when towing a trailer:
. Have the exhaust system
inspected for leaks and make necessary repairs before starting a trip.
. Never drive with the liftgate,
trunk/hatch, or rear-most window open.
(Continued)
WARNING (Continued)
. Fully open the air outlets on
or under the instrument panel.
. Adjust the Climate Control
system to a setting that brings in only outside air and set the fan speed to the highest setting. See Climate Control System in the Index.
For more information about Carbon Monoxide, see Engine Exhaust on page 9‑33.
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. While towing a trailer or when exposed to long periods of sunshine, the floor of the truck bed may become very warm. Avoid putting items in the truck bed that might be affected by high ambient temperatures.
Chevrolet Colorado Owner Manual - 2011
Black plate (58,1)

Driving and Operating
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 will not 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 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. Vehicles with automatic transmissions can tow in D (Drive), but you may want to shift to a lower gear selection if the transmission shifts too often (e.g., under heavy loads and/or hilly conditions). If the vehicle has a manual transmission it is better not to use the highest gear. When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at a lower temperature than at normal

If parking the rig on a hill: 1. Press the brake pedal, but do
not shift into P (Park) yet for vehicles with an automatic transmission, or into gear for vehicles with a manual transmission. 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 into P (Park) for vehicles with an automatic transmission or into gear for vehicles with a manual transmission.

To avoid this, let the engine run while parked, preferably on level ground, with an automatic transmission in P (Park) or a manual transmission in N (Neutral) with the parking brake applied, for a few minutes before turning the engine off. If the overheat warning comes on, see Engine Overheating on page 10‑23. Parking on Hills
{ WARNING
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.

Maintenance When Trailer Towing The vehicle needs service more often when pulling a trailer. See Scheduled Maintenance on page 11‑2 or the Index 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 Towing
{ WARNING
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 for advice and information about towing a trailer with the vehicle.
Notice: Pulling a trailer improperly can damage the vehicle and result in costly repairs not covered by the vehicle warranty. To pull a trailer correctly, follow the advice in this section and see your dealer for important 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.

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.

*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment and conversions. The GCWR for the vehicle should not be exceeded.
Ask your dealer for our trailering information or advice, or write us at our Customer Assistance Offices. See Customer Assistance Offices (U.S. and Canada) on page 13‑4 or Customer Assistance Offices (Mexico) on page 13‑5 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
Vehicle Load Limits on page 9‑20
for more information about the
vehicle's maximum load capacity.

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 located at the bottom of the center pillar on the driver's side of the vehicle, or see Vehicle Load Limits on page 9‑20. Make sure not to go over the GVW limit for the vehicle, or the GAWR, including the weight of the trailer tongue. If using a weight distributing hitch, make sure not to go over the rear axle limit before applying the weight distribution spring bars.
After loading the trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they are not, adjustments might be made by moving some items around in the trailer. Trailering may 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 weight may reduce the trailering capacity more than the total of the additional weight. 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.
The trailer tongue weight (A) should be 10 percent to 15 percent of the total loaded trailer weight, up to a maximum of 226 kg (500 lbs) with a weight carrying hitch. Do not exceed the maximum allowable tongue weight for the vehicle. Choose the shortest hitch extension that will position the hitch ball closest to the vehicle. This will help reduce the effect of trailer tongue weight on the rear axle.

Towing Equipment
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. Weight-Distributing Hitches and Weight Carrying Hitches A step bumper hitch can be used for trailers up to 907 kg (2,000 lbs) total weight, and 90 kg (200 lbs) tongue weight. Notice: If a step-bumper hitch is used, the bumper could be damaged in sharp turns. Make sure there is ample room when turning to avoid contact between the trailer and the bumper.
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. For trailers up to 907 kg (2,000 lbs) safety chains may be attached to the attaching points on the bumper. For heavier trailers, follow the trailer or hitch manufacturer's recommendation for attaching safety chains. 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 450 kg (1,000 lbs) 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. Since the vehicle is equipped with StabiliTrak®, the trailer cannot tap into the vehicle's hydraulic brake system. Trailer Wiring Harness The vehicle may be equipped with a four‐pin trailer towing harness. This harness has a four‐pin trailer connector that is attached to a bracket on the hitch platform. The four‐wire harness contains the following trailer circuits: . Yellow: Left Stop/Turn Signal . Green: Right Stop/Turn Signal . Brown: Taillamps/Park lamps . White: Ground

Pickup Conversion to Chassis Cab We are aware that some vehicle owners might consider having the pickup box removed and a commercial or recreational body installed. However, we recommend that conversions of this type not be done to pickups. Owners should be aware that, as manufactured, there are differences between a chassis cab and a pickup with the box removed which could affect vehicle safety.

Engine Oil To ensure proper engine performance and long life, careful attention must be paid to engine oil. Following these simple, but important steps will help protect your investment: . Always use engine oil approved to the proper specification and of the proper viscosity grade. See “Selecting the Right Engine Oil” in this section.
. Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section.
Vehicle Care
10-9
. Change the engine oil at the
appropriate time. See Engine Oil Life System on page 10‑12. . Always dispose of engine oil
properly. See “What to Do with Used Oil” in this section.
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 vehicle must be on level ground. The engine oil dipstick handle is a yellow loop. See Engine Compartment Overview on page 10‑6 for the location of the engine oil dipstick. Obtaining an accurate oil level reading is essential: 1.
If the engine has been running recently, turn off the engine and allow several minutes for the oil to drain back into the oil pan. Checking the oil level too soon after engine shutoff will not provide an accurate oil level reading.

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
L4 and L5 Engines
V8 Engine
If the oil is below the cross-hatched area at the tip of the dipstick, add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” in this section for an explanation of
what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 12‑2. Notice: Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If you find that you have an oil level above the operating range, i.e., the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. You should drain out the excess oil or limit driving of the vehicle and seek a service professional to remove the excess amount of oil. See Engine Compartment Overview on page 10‑6 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.
