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.
If parking the rig on a hill:
1. Press the brake pedal, but donot shift into P (Park) yet. Turnthe wheels into the curb iffacing downhill or into traffic iffacing uphill.
2. Have someone place chocksunder the trailer wheels.
3. When the wheel chocks are inplace, release the regularbrakes until the chocks absorbthe load.
4. Reapply the brake pedal. Thenapply the parking brake andshift into P (Park).
5. Release the brake pedal.

7. Stop and have someone pickup and store the chocks.
Maintenance when Trailer
Towing
The vehicle needs service moreoften when pulling a trailer. SeeMaintenance Schedule0366.Things that are especially importantin trailer operation are automatictransmission fluid, engine oil, axlelubricant, belts, cooling system, and
brake system. It is a good idea toinspect these before and duringthe trip.
Check periodically to see that allhitch nuts and bolts are tight.
Trailer Towing
Do not tow a trailer during break-in.SeeNew Vehicle Break-In0232.
{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
or the trailer brakes are
inadequate for the load, the
vehicle may not stop as expected.
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.

Warning (Continued)
Ask your dealer for advice and
information about towing a trailer
with the vehicle.
Caution
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.
SeeVehicle Load Limits0226formore information about the vehicle'smaximum load capacity.
To i d e n t i f y t h e t r a i l e r i n g c a p a c i t y o fthe vehicle, read the information in“Weight of the Trailer”later in thissection.
Trailering is different than justdriving the vehicle by itself.Trailering means changes in
handling, acceleration, braking,durability, and fuel economy.Successful, safe trailering takescorrect equipment, and it has to beused properly.
The following information has manytime-tested, important trailering tipsand safety rules. Many of these areimportant for your safety and that ofyour passengers. Read this sectioncarefully before pulling a trailer.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how the rig is used.Speed, altitude, road grades,outside temperature, and how muchthe vehicle is used to pull a trailerare all important. It can depend onany special equipment on thevehicle, and the amount of tongueweight the vehicle can carry. See“Weight of the Trailer Tongue”laterin this section for more information.
Trailer Weight Rating (TWR) iscalculated assuming the tow vehiclehas only the driver but all requiredtrailering equipment. Weight ofadditional optional equipment,
passengers, and cargo in the towvehicle must be subtracted from thetrailer weight rating.
Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle model andoptions.

3.6L V6 3.42 3 175 kg (7,000 lb) 5 443 kg (12,000 lb)
(a) The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicleand trailer including any passengers, cargo, equipment, and conversions. The GCWR for the vehicle should not beexceeded.
Ask your dealer for traileringinformation or advice.
Weight of the Trailer Tongue
The tongue load (1) of any trailer isvery important because it is alsopart of the vehicle weight. TheGross Vehicle Weight (GVW)includes the curb weight of thevehicle, any cargo carried in it, andthe people who will be riding in thevehicle as well as trailer tongueweight. Vehicle options, equipment,passengers and cargo in the vehiclereduce the amount of tongue weightthe vehicle can carry, which will alsoreduce the trailer weight the vehiclecan tow.
Trailer tongue weight (1) should be10–15% of the loaded trailerweight (2) up to 408 kg (900 lb).
Trailer rating may be limited by thevehicle's ability to carry tongueweight. Tongue weight cannot cause
the vehicle to exceed theGVWR (Gross Vehicle WeightRating) or the RGAWR (Rear GrossAxle Weight Rating).
After loading the trailer, weigh thetrailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving someitems around in the trailer.
Total Weight on the Vehicle's
Tires
Be sure the vehicle's tires areinflated to the inflation pressuresfound on the Certification/Tire labelon the center pillar or seeVehicleLoad Limits0226.Makesurenotto

Chevrolet Colorado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-10122675) - 2017 - crc - 8/22/16
Driving and Operating 275
exceed the GVWR limit for thevehicle, or the RGAWR, with the towvehicle and trailer fully loaded forthe trip including the weight of thetrailer tongue. If using aweight-distributing hitch, make surenot to exceed the RGAWR beforeapplying the weight distributionspring bars.
Weight of the Trailering
Combination
It is important that the combinationof the tow vehicle and trailer doesnot exceed any of its weight ratings—GCWR, GVWR, RGAWR, TrailerWeight Rating, or Tongue Weight.The only way to be sure it is notexceeding any of these ratings is toweigh the tow vehicle and trailercombination, fully loaded for the trip,getting individual weights for each ofthese items.
Towing Equipment
Hitches
The correct hitch equipment helpsmaintain combination control. Manytrailers can be towed with a
weight-carrying hitch which simplyfeatures a coupler latched to thehitch ball, or a tow eye latched to apintle hook. Other trailers mayrequire a weight-distributing hitchthat uses spring bars to distributethe trailer tongue weight among thetow vehicle and trailer axles.
If a step-bumper hitch will be used,the bumper could be damaged insharp turns. Make sure thereis ample room when turning to avoidcontact between the trailer and thebumper.
Astep-bumperhitchislimitedto1587kg(3,500lb)totalweight.
Consider using sway controls withany trailer. Ask a traileringprofessional about sway controls orrefer to the trailer manufacturer'srecommendations and instructions.
Weight-Distributing Hitch
Adjustment
Aweight-distributinghitchmaybeuseful with some trailers.
1. Front of Vehicle
2. Body to Ground Distance
When using a weight-distributinghitch, the spring bars should beadjusted so the distance (2) is thesame after coupling the trailer to thetow vehicle and adjusting the hitch.
Safety Chains
Always attach chains between thevehicle and the trailer. Cross thesafety chains under the tongue ofthe trailer to help prevent the tonguefrom contacting the road if itbecomes separated from the hitch.Instructions about safety chainsmay be provided by the hitch

manufacturer or by the trailermanufacturer. Always leave justenough slack so the combinationcan turn. Never allow safety chainsto drag on the ground.
Trailer Brakes
Aloadedtrailerthatweighsmorethan 900 kg (2,000 lb) needs to haveits own brake system that isadequate for the weight of thetrailer. Be sure to read and followthe instructions for the trailer brakesso they are installed, adjusted, andmaintained properly.
Trailer Wiring Harness
For vehicles not equipped withheavy-duty trailering, a harness issecured underneath the left side ofthe vehicle, next to the spare tire.The harness requires the installationof a trailer connector, which isavailable through your dealer. Theseven-wire harness contains thefollowing trailer circuits:
.Ye l l o w : L e f t s t o p / t u r n s i g n a l

.When pulling a heavy trailer or alarge or heavy load throughrolling terrain.
.When pulling a heavy trailer or alarge or heavy load instop-and-go traffic.
.When pulling a heavy trailer or alarge or heavy load in busyparking lots where improved lowspeed control of the vehicle isdesired.
Operating the vehicle in Tow/Haulwhen lightly loaded or with no trailerat all will not cause damage.However, there is no benefit to theselection of Tow/Haul when thevehicle is unloaded. Such aselection when unloaded may resultin unpleasant engine andtransmission driving characteristicsand reduced fuel economy. Tow/Haul is recommended only whenpulling a heavy trailer or a large orheavy load.
If the vehicle has a diesel engine,the Tow/Haul button activates theexhaust brake systemsimultaneously. See“ExhaustBrake”in the Duramax dieselsupplement.
Trailer Sway
Control (TSC)
Vehicles with StabiliTrak have aTrailer Sway Control (TSC) feature.Trailer sway is unintendedside-to-side motion of a trailer whilebeing towed. If the vehicle is towingatrailerandtheTSCdetectsthatsway is increasing, the vehiclebrakes are selectively applied ateach wheel, to help reduceexcessive trailer sway. If the vehicleis equipped with the IntegratedTrailer Brake Control (ITBC) system,and the trailer has the electricactuated brake system, StabiliTrakmay also apply the trailer brakes.
If TSC is enabled, the TractionControl System (TCS)/StabiliTrakwarning light will flash on theinstrument cluster. Vehicle speedmust be reduced. If trailer swaycontinues, StabiliTrak can reduceengine torque to help slow thevehicle. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0256.
