{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

the fan speed to the highestsetting. See“ClimateControl Systems.”
For more information about CO,
seeEngine Exhaust0276.
To s a v e f u e l , r u n t h e e n g i n e f o rshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.
If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.See“Rocking the Vehicle to Get ItOut”later in this section.
The Traction Control System (TCS)can often help to free a stuckvehicle. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0295.If TCS cannot free the vehicle, see“Rocking the Vehicle to Get it Out”following.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
For information about using tirechains on the vehicle, seeTireChains0419.

.The trailer must be equippedwith brakes adequate for theintended use. A loaded trailerweighing more than 900 kg(2,000 lb) must be equipped withits own brake system, withbrakes working on all axles.Trailer braking equipmentconforming to CanadianStandards Association (CSA)requirement CAN3-D313, or itsequivalent, is recommended.
.Do not tow a trailer during thefirst 800 km (500 mi) to preventdamage to the engine, axle,or other parts.
.Then during the first 800 km(500 mi) of trailer towing, do notdrive over 80 km/h (50 mph) anddo not make starts at full throttle.
.Vehicles can tow in D (Drive).The Tow/Haul Mode may beused if the transmission shiftstoo often. SeeTo w / H a u lMode0282.
.Turn off Park Assist whentowing.
{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.
When towing a trailer:
.Do not drive with theliftgate, trunk/hatch,or rear-most window open.
.Fully open the air outlets onor under the instrumentpanel.
.Also adjust the climatecontrol system to a settingthat brings in only outsideair. See“Climate ControlSystems”in the Index.

carbon monoxide, seeEngine
Exhaust0276.
To w i n g a t r a i l e r r e q u i r e s a c e r t a i namount of experience. Thecombination you are driving islonger and not as responsive as the
vehicle itself. Get acquainted withthe handling and braking of the rigbefore setting out for the open road.
The structure, tires, and brakes ofthe trailer must be rated to carry theload. Inadequate trailer equipmentcan cause the combination tooperate in an unexpected or unsafemanner.
Before starting, check all trailer hitchparts and attachments, safetychains, electrical connectors, lamps,tires, and mirrors. Get familiar withthe handling and braking of the rig.If the trailer has electric brakes, startthe combination moving and thenapply the trailer brake controller byhand to be sure the brakes work.
During the trip, check occasionallyto be sure that the load is secureand the lamps and any trailerbrakes still work.
Following Distance
Stay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid heavybraking and sudden turns.

Overload
The vehicle has fuses to protectagainst an electrical systemoverload. Fuses also protect powerdevices in the vehicle.
Replace a bad fuse with a new oneof the identical size and rating.
If there is a problem on the road andafuseneedstobereplaced,thereare some spare fuses and a fusepuller in the Instrument Panel FuseBlock. The same amperage fusecan also be borrowed. Choosesome feature of the vehicle that isnot needed to use and replace it assoon as possible.

Headlamp Wiring
An electrical overload may causethe lamps to go on and off, or insome cases to remain off. Have theheadlamp wiring checked right awayif the lamps go on and off orremain off.
Windshield Wipers
If the wiper motor overheats due toheavy snow or ice, the windshieldwipers will stop until the motor coolsand will then restart.
Although the circuit is protectedfrom electrical overload, overloaddue to heavy snow or ice maycause wiper linkage damage.Always clear ice and heavy snowfrom the windshield before using thewindshield wipers.
If the overload is caused by anelectrical problem and not snow orice, be sure to get it fixed.
Fuses
The wiring circuits in the vehicle areprotected from short circuits byfuses. This greatly reduces thechance of fires caused by electricalproblems.
Look at the silver-colored bandinside the fuse. If the band is brokenor melted, replace the fuse. Be sureyou replace a bad fuse with a newone of the identical size and rating.
Fuses of the same amperage canbe temporarily borrowed fromanother fuse location, if a fuse goesout. Replace the fuse as soon asyou can.
Engine Compartment
Fuse Block
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
The engine compartment fuse blockis in the engine compartment, onthe driver side of the vehicle.
Lift the cover to access the fuseblock.
Caution
Spilling liquid on any electrical
component on the vehicle may
damage it. Always keep the
covers on any electrical
component.
