Maintenance when Trailer
Towing
The vehicle needs service moreoften when pulling a trailer. SeeMaintenance Schedule0452.Things that are especially importantin trailer operation are automatictransmission fluid, engine oil, axlelubricant, belts, cooling system, andbrake 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
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
If the vehicle is bi-fuel, see thebi-fuel supplement.
Do not tow a trailer during break-in.SeeNew Vehicle Break-In0267.
{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.
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

selection 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.
Integrated Trailer Brake
Control System
The vehicle may have an IntegratedTrailer Brake Control (ITBC) systemfor use with electric trailer brakes ormost electric over hydraulic trailerbrakes.
This symbol is on the Trailer BrakeControl Panel on vehicles with anITBC system. The power output tothe trailer brakes is based on theamount of brake pressure beingapplied by the vehicle’sbrake
system, and on the type of trailerbrakes detected. This availablepower output to the trailer brakescan be adjusted to a wide range oftrailering situations.
The ITBC system is integrated withthe vehicle’sbrake,antilockbrake,and StabiliTrak systems. In traileringconditions that cause the vehicle’santilock brake or StabiliTraksystems to activate, power sent tothe trailer's brakes will beautomatically adjusted to minimizetrailer wheel lock-up. This does notimply that the trailer has StabiliTrak.
If the vehicle’sbrake,antilockbrake,or StabiliTrak systems are notfunctioning properly, the ITBCsystem may not be fully functionalor may not function at all. Make sureall of these systems are fullyoperational to ensure fullfunctionality of the ITBC system.
The ITBC system is poweredthrough the vehicle's electricalsystem. Turning the ignition off willalso turn off the ITBC system. TheITBC system is fully functional onlywhen the ignition is in ON/RUN.
{Warning
Connecting a trailer that has an
air brake system may result in
reduced or complete loss of trailer
braking. There may be an
increase in stopping distance or
trailer instability which could
result in personal injury or
damage to the vehicle, trailer,
or other property. Use the ITBC
system only with electric or
electric over hydraulic trailer
brakes.

Manual Trailer Brake Apply
The Manual Trailer Brake ApplyLever is used to apply the trailer’selectric brakes independent of thevehicle’sbrakes.Slidingthelevertothe left will apply only the trailerbrakes. Use this lever to adjustTrailer Gain to properly adjust thepower output to the trailer brakes.
The trailer's and the vehicle's brakelamps will come on when eithervehicle brakes or manual trailerbrakes are applied.
Trailer Gain Adjustment Procedure
Trailer Gain should be set for aspecific trailering condition and mustbe adjusted anytime vehicle loading,trailer loading, or road surfaceconditions change.
{Warning
Trailer brakes that are
over-gained or under-gained may
not stop the vehicle and the trailer
as intended and can result in a
crash. Always follow the
instructions to set the Trailer Gain
for the proper trailer stopping
performance.
Use the following to adjust TrailerGain for each towing condition:
1. Drive the vehicle with the trailerattached on a level roadsurface representative of thetowing condition and free oftraffic at about 32 to 40 km/h(20 to 25 mph) and fully applythe Manual Trailer Brake ApplyLever.
Adjusting Trailer Gain atspeeds lower than 32 to40 km/h (20 to 25 mph) mayresult in an incorrect gainsetting.
2. Adjust the Trailer Gain, usingthe Trailer Gain AdjustmentButtons, to just below the pointof trailer wheel lock-up,indicated by trailer wheelsqueal or tire smoke when atrailer wheel locks.
Trailer wheel lock-up may notoccur if towing a heavily loadedtrailer. In this case, adjust theTrailer Gain to the highestallowable setting for the towingcondition.
3. Readjust Trailer Gain anytimevehicle loading, trailer loading,or road surface conditionschange or if trailer wheellock-up is noticed at any timewhile towing.

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 Control0295.
{Warning
Even if the vehicle is equipped
with TSC, trailer sway could result
in loss of control and the vehicle
could crash. If excessive trailer
sway is detected, slow down to a
safe speed. Check the trailer and
vehicle to help correct possible
causes. These could include an
improperly or overloaded trailer,

Adding a Snow Plow or
Similar Equipment
Caution
Do not exceed 72 km/h (45 mph)
with a snow plow mounted to the
vehicle. The vehicle could
overheat and be damaged.
Before installing a snow plow on thevehicle, follow these guidelines:
Caution
If the vehicle does not have the
snow plow prep package, RPO
VYU, adding a plow can damage
the vehicle, and the repairs would
not be covered by the vehicle
warranty. Unless the vehicle was
built to carry a snow plow, do not
add one to the vehicle. If the
vehicle has RPO VYU, then the
payload the vehicle can carry will
be reduced when a snow plow is
installed. The vehicle can be

For example, adding a 318 kg(700 lb) snow plow actually addsmore than 318 kg (700 lb) to thefront axle. Using the formula, if thesnow plow is 122 cm (4 ft) in front ofthe front axle and the wheelbase is305 cm (10 ft), then:W=318kg(700lb)A=122cm(4ft)W.B. = 305 cm (10 ft)
(W x (A + W.B.)/W.B. =(318 x (122 + 305))/305 = 445 kg(980 lb)
This means if the front axle reservecapacity is more than 445 kg(980 lb), the snow plow could beadded without exceeding thefront GAWR.
Heavier equipment can be added onthe front of the vehicle if less cargoor fewer passengers are carried,or by positioning cargo toward therear. This reduces the load on thefront. However, the front GAWR,rear GAWR, and Gross VehicleWeight Rating (GVWR) must neverbe exceeded.
{Warning
On some vehicles that have
certain front mounted equipment,
such as a snow plow, it may be
possible to load the front axle to
the front Gross Axle Weight
Rating (GAWR) but not have
enough weight on the rear axle to
have proper braking performance.
If the brakes cannot work
properly, the vehice could crash.
Always follow the snow plow
manufacturer or installer's
recommendation for rear ballast
to ensure a proper front and rear
weight distribution ratio.
Maintaining a proper front and
rear weight distribution ratio is
necessary to provide proper
braking performance.
To t a l v e h i c l e r e s e r v e c a p a c i t y i s t h edifference between the GVWR andthe weight of the truck with full fueland passengers. It is the amount ofweight that can be added to thevehicle before reaching the GVWR.Reserve capacity numbers are
intended as a guide when selectingthe amount of equipment or cargothe truck can carry. If unsure of thevehicle's front, rear, or total weight,go to a weigh station and weigh thevehicle. Your dealer can also helpwith this.
The total vehicle reserve capacityfor the vehicle is in the lower rightcorner of the Certification/Tire labelas shown previously.
