282 Driving and Operating
If the vehicle has an exhaust brake,it can also be used, but will notautomatically downshift thetransmission. See“Exhaust Brake”in the Duramax diesel supplement.
Caution
Spinning the tires or holding the
vehicle in one place on a hill
using only the accelerator pedal
may damage the transmission.
The repair will not be covered by
the vehicle warranty. If you are
stuck, do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
Low Traction Mode
If equipped, Low Traction Modeassists in vehicle acceleration whenroad conditions are slippery, suchas with ice or snow. While thevehicle is at a stop, select L2 usingRange Selection Mode. This willlimit torque to the wheels and helpto prevent the tires from spinning.
Tow/Haul Mode
Vehicles with an automatictransmission have a Tow/HaulMode. The Tow/Haul Mode adjuststhe transmission shift pattern toreduce shift cycling. This providesincreased performance, vehiclecontrol, and enhanced transmissionand engine cooling when drivingdown steep hills or mountaingrades, when towing, or whenhauling heavy loads.
The selector button is on the end ofthe shift lever. Turn the Tow/HaulMode on and off by pressing the
button. When the Tow/Haul Mode isenabled, a light on the instrumentcluster will come on.
For an eAssist vehicle, the Stop/Start function will becomeunavailable when Tow/Haul Mode isactive.
For an eAssist vehicle, theRegenerative Braking functionality isdisabled when using the Tow/HaulMode. See the eAssist supplement.

Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock BrakeSystem (ABS), an advancedelectronic braking system that helpsprevent a braking skid.
When the vehicle begins to driveaway, ABS checks itself.Amomentarymotororclickingnoisemay be heard while this test is goingon, and it may even be noticed thatthe brake pedal moves a little. Thisis normal.
If there is a problem with ABS, thiswarning light stays on. SeeAntilockBrake System (ABS) WarningLight0141.
If driving safely on a wet road and itbecomes necessary to slam on thebrakes and continue braking toavoid a sudden obstacle, acomputer senses the wheels areslowing down. If one of the wheelsis about to stop rolling, the computerwill separately work the brakes ateach wheel.
ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpyou steer around the obstacle whilebraking hard.
As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.
Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehiclesuddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.
