Driving Information
Distracted Driving
Distraction comes in many formsand can take your focus from thetask of driving. Exercise goodjudgment and do not let otheractivities divert your attention awayfrom the road. Many localgovernments have enacted lawsregarding driver distraction. Becomefamiliar with the local laws inyour area.
To a v o i d d i s t r a c t e d d r i v i n g , k e e pyour eyes on the road, keep yourhands on the steering wheel, andfocus your attention on driving.
.Do not use a phone indemanding driving situations.Use a hands-free method toplace or receive necessaryphone calls.
.Watch the road. Do not read,take notes, or look upinformation on phones or otherelectronic devices.
.Designate a front seatpassenger to handle potentialdistractions.
.Become familiar with vehiclefeatures before driving, such asprogramming favorite radiostations and adjusting climatecontrol and seat settings.Program all trip information intoany navigation device prior todriving.
.Wait until the vehicle is parkedto retrieve items that have fallento the floor.
.Stop or park the vehicle to tendto children.
.Keep pets in an appropriatecarrier or restraint.
.Avoid stressful conversationswhile driving, whether with apassenger or on a cell phone.
{Warning

long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.
Refer to the infotainment section formore information on using thatsystem and the navigation system,if equipped, including pairing andusing a cell phone.
Defensive Driving
Defensive driving means“alwaysexpect the unexpected.”The firststep in driving defensively is to wearthe safety belt. SeeSafetyBelts046.
.Assume that other road users(pedestrians, bicyclists, andother drivers) are going to becareless and make mistakes.Anticipate what they might doand be ready.

166 Driving and Operating
Drunk Driving
Death and injury associated withdrinking and driving is a globaltragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
asmallamountofalcohol.You
can have a serious—or even
fatal—collision if you drive after
drinking.
Do not drink and drive or ride with
adriverwhohasbeendrinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and acceleratingare important factors in helping tocontrol a vehicle while driving.
Braking
Braking action involves perceptiontime and reaction time. Deciding topush the brake pedal is perceptiontime. Actually doing it isreaction time.
Average driver reaction time isabout three-quarters of a second. Inthat time, a vehicle moving at100 km/h (60 mph) travels 20 m(66 ft), which could be a lot ofdistance in an emergency.
Helpful braking tips to keep in mindinclude:
.Keep enough distance betweenyou and the vehicle in frontof you.
.Avoid needless heavy braking.
.Keep pace with traffic.
If the engine ever stops while thevehicle is being driven, brakenormally but do not pump thebrakes. Doing so could make thepedal harder to push down. If theengine stops, there will be somepower brake assist but it will beused when the brake is applied.
Once the power assist is used up, itcan take longer to stop and thebrake pedal will be harder to push.
Steering
Hydraulic Power Steering
Yo u r v e h i c l e h a s h y d r a u l i c p o w e rsteering. It may requiremaintenance. SeePower SteeringFluid0232.
If power steering assist is lostbecause the engine stops orbecause of a system malfunction,the vehicle can be steered but mayrequired increased effort. See yourdealer if there is a problem.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
for more than 15 seconds,
damage may occur to the power
steering system and there may be
loss of power steering assist.

Curve Tips
.Ta k e c u r v e s a t a r e a s o n a b l espeed.
.Reduce speed before entering acurve.
.Maintain a reasonable steadyspeed through the curve
.Wait until the vehicle is out ofthe curve before acceleratinggently into the straightaway.
Steering in Emergencies
.There are some situations whensteering around a problem maybe more effective than braking.
.Holding both sides of thesteering wheel allows you to turn180 degrees without removingahand.
.Antilock Brake System (ABS)allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can dropoff the edge of a road onto theshoulder while driving. Followthese tips:
1. Ease off the accelerator andthen, if there is nothing in theway, steer the vehicle so that itstraddles the edge of thepavement.
2. Turn the steering wheel aboutone-eighth of a turn, until theright front tire contacts thepavement edge.
3. Turn the steering wheel to gostraight down the roadway.
Loss of Control
Skidding
There are three types of skids thatcorrespond to the vehicle's threecontrol systems:
.Braking Skid—wheels are notrolling.
.Steering or Cornering Skid—too much speed or steering in acurve causes tires to slip andlose cornering force.
.Acceleration Skid—too muchthrottle causes the drivingwheels to spin.
Defensive drivers avoid most skidsby taking reasonable care suited toexisting conditions, and by notoverdriving those conditions. Butskids are always possible.
If the vehicle starts to slide, followthese suggestions:
.Ease your foot off theaccelerator pedal and steer theway you want the vehicle to go.

Driving and Operating 169
.Keep the windshield washer fluidreservoir filled.
.Have good tires with propertread depth. SeeTires0252.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips include:
.Keep the vehicle serviced and ingood shape.
.Check all fluid levels and brakes,tires, cooling system, andtransmission.
.Shift to a lower gear when goingdown steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
(Continued)
Warning (Continued)
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
.Drive at speeds that keep thevehicle in its own lane. Do notswing wide or cross thecenter line.
.Be alert on top of hills;something could be in your lane(e.g., stalled car, accident).
.Pay attention to special roadsigns (e.g., falling rocks area,winding roads, long grades,passing or no-passing zones)and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires andthe road creates less traction orgrip, so drive carefully. Wet ice canoccur at about 0 °C (32 °F) whenfreezing rain begins to fall. Avoiddriving on wet ice or in freezing rainuntil roads can be treated.
For slippery road driving:
.Accelerate gently. Acceleratingtoo quickly causes the wheels tospin and makes the surfaceunder the tires slick.
.Turn on Traction Control. SeeTr a c t i o n C o n t r o l / E l e c t r o n i cStability Control0190.
.Antilock Brake System (ABS)improves vehicle stability duringhard stops, but the brakesshould be applied sooner than

Driving and Operating 171
If the Vehicle Is Stuck
Slowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.
If stuck too severely for the tractionsystem to free the vehicle, turn thetraction system off and use therocking method. SeeTr a c t i o nControl/Electronic StabilityControl0190.
{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).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left andright to clear the area around thefront wheels. Turn off any tractionsystem. Shift back and forth
between R (Reverse) and a lowforward gear, spinning the wheelsas little as possible. To preventtransmission wear, wait until thewheels stop spinning before shiftinggears. Release the acceleratorpedal while shifting, and presslightly on the accelerator pedalwhen the transmission is in gear.Slowly spinning the wheels in theforward and reverse directionscauses a rocking motion that couldfree the vehicle. If that does not getthe vehicle out after a few tries, itmight need to be towed out. If thevehicle does need to be towed out,seeTo w i n g t h e V e h i c l e0286.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle may
show how much weight it was
designed to carry, the Tire and
Loading Information label and
the Certification/Tire label.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.

Starting the Engine
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
To p l a c e t h e t r a n s m i s s i o n i n t h eproper gear:
Move the shift lever to P (Park) orN(Neutral). The engine will not startin any other position. To restart theengine when the vehicle is alreadymoving, use N (Neutral) only.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
SeeAdd-On Electrical
Equipment0212.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
while starting the vehicle, damage
may occur to the hydraulic power
steering system and there may be
loss of power steering assist.
Starting Procedure
1. With your foot off theaccelerator pedal, turn theignition key to START. Whenthe engine starts, let go of thekey. The idle speed will godown as your engine getswarm. Do not race the engineimmediately after starting it.

178 Driving and Operating
Operate the engine andtransmission gently to allow theoil to warm up and lubricate allmoving parts.
When the Low Fuel warninglamp is on and the FUELLEVEL LOW message isdisplayed in the DriverInformation Center (DIC), theComputer-Controlled CrankingSystem is disabled to preventpossible vehicle componentdamage. When this happens,hold the ignition switch in theSTART position to continueengine cranking.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not startafter 5-10 seconds, especiallyin very cold weather (below✓18 °C or 0 °F), it could beflooded with too muchgasoline. Try pushing theaccelerator pedal all the way tothe floor and holding it there asyou hold the key in START forup to 15 seconds. Wait at least15 seconds between each try,to allow the cranking motor tocool down. When the enginestarts, let go of the key andaccelerator. If the vehicle startsbriefly but then stops again, dothe same thing. This clears theextra gasoline from the engine.Do not race the engineimmediately after starting it.Operate the engine andtransmission gently until the oilwarms up and lubricates allmoving parts.
Fast Idle System
If equipped, this feature is availableonly with cruise control. The manualfast idle switch is operated using thecruise control buttons on the leftside of the steering wheel.
This system can be used toincrease engine idle speedwhenever the following conditionsare met:
.The parking brake is set.
.The brake pedal is not pressed.
.The vehicle must not be movingand the accelerator must not bepressed.
