{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
Yo u c o u l d l o s e c o n t r o l a n d h i t
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Caution
Shifting out of P (Park) or
N(Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D:This position is for normaldriving. It provides the best fueleconomy. If you need more powerfor passing, and you are:
.Going less than 56 km/h(35 mph), push the acceleratorpedal about halfway down.
.Going about 56 km/h (35 mph) ormore, push the accelerator allthe way down.
M:This position allows you tochange gears similar to a manualtransmission. If equipped, see“Manual Mode”following.
Operating Modes
The transmission may operate in alower gear than normal to improvevehicle performance. The enginespeed may be higher and there maybe an increase in noise during thefollowing conditions:
.When climbing a grade.
.When driving downhill.
.When driving in hottemperatures or at high altitude.

Up-Shift Light
Vehicles equipped with a manualtransmission have an up-shift light.This light indicates when to shift tothe next higher gear for better fueleconomy.
For the best fuel economy,accelerate slowly and shift when thelight comes on, and if the weather,road, and traffic conditions allow.
It is normal for the light to go on andoff if the accelerator positionchanges quickly. Ignore the lightduring downshifts.
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) WarningLight011 5.
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.

196 Driving and Operating
Using ABS
Do not pump the brakes. Just holdthe brake pedal down firmly and letABS work. You may hear the ABSpump or motor operating and feelthe brake pedal pulsate. This isnormal.
Braking in Emergencies
ABS allows you to steer and brakeat the same time. In manyemergencies, steering can helpmore than even the very bestbraking.
Parking Brake
To s e t t h e p a r k i n g b r a k e , h o l d t h ebrake pedal down and pull up on theparking brake lever. If the ignition ison, the brake system warning lightwill come on. SeeBrake SystemWarning Light011 4.
To r e l e a s e t h e p a r k i n g b r a k e , h o l dthe brake pedal down. Pull theparking brake lever up until you canpress the release button. Hold therelease button in as you move thebrake lever all the way down.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Brake Assist
The Brake Assist feature isdesigned to assist the driver instopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplement thepower brake system underconditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle. Thestability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.Minor brake pedal pulsation orpedal movement during this time isnormal and the driver shouldcontinue to apply the brake pedal asthe driving situation dictates. TheBrake Assist feature willautomatically disengage when thebrake pedal is released or brakepedal pressure is quicklydecreased.

Hill Start Assist (HSA)
This vehicle has a Hill Start Assist(HSA) feature, which may be usefulwhen the vehicle is stopped on agrade sufficient enough to activateHSA. This feature is designed toprevent the vehicle from rolling,either forward or rearward, duringvehicle drive off. After the drivercompletely stops and holds thevehicle in a complete standstill on agrade, HSA will be automaticallyactivated. During the transitionperiod between when the driverreleases the brake pedal and startsto accelerate to drive off on a grade,HSA holds the braking pressure foramaximumoftwosecondstoensure that there is no rolling. Thebrakes will automatically releasewhen the accelerator pedal isapplied within the two-secondwindow. It will not activate if thevehicle is in a drive gear and facingdownhill, or if the vehicle is facinguphill and in R (Reverse).
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction ControlSystem (TCS) and StabiliTrak®,anelectronic stability control system.These systems help limit wheel slipand assist the driver in maintainingcontrol, especially on slippery roadconditions.
TCS activates if it senses that anyof the drive wheels are spinning orbeginning to lose traction. When thishappens, TCS applies the brakes tothe spinning wheels and reducesengine power to limit wheel spin.
StabiliTrak activates when thevehicle senses a difference betweenthe intended path and the directionthe vehicle is actually traveling.StabiliTrak selectively appliesbraking pressure to any one of the
vehicle wheel brakes to assist thedriver in keeping the vehicle on theintended path.
If cruise control is being used andtraction control or StabiliTrak beginsto limit wheel spin, cruise control willdisengage. Cruise control may beturned back on when roadconditions allow.
Both systems come onautomatically when the vehicle isstarted and begins to move. Thesystems may be heard or felt whilethey are operating or whileperforming diagnostic checks. Thisis normal and does not mean thereis a problem with the vehicle.
It is recommended to leave bothsystems on for normal drivingconditions, but it may be necessaryto turn TCS off if the vehicle getsstuck in sand, mud, ice, or snow.SeeIf the Vehicle Is Stuck0178and“Turning the Systems Off andOn”later in this section.

198 Driving and Operating
The indicator light for both systemsis in the instrument cluster. Thislight will:
.Flash when TCS is limitingwheel spin.
.Flash when StabiliTrak isactivated.
.Turn on and stay on when eithersystem is not working.
If either system fails to turn on or toactivate, a message displays in theDriver Information Center (DIC), anddcomes on and stays on toindicate that the system is inactiveand is not assisting the driver inmaintaining control. The vehicle issafe to drive, but driving should beadjusted accordingly.
Ifdcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait15 seconds.
3. Start the engine.
Drive the vehicle. Ifdcomes on
and stays on, the vehicle may needmore time to diagnose the problem.If the condition persists, see yourdealer.

Cruise Control
If the vehicle is equipped with cruisecontrol, a speed of about 40 km/h(25 mph) or more can be maintainedwithout keeping your foot on theaccelerator. Cruise control does notwork at speeds below 40 km/h(25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
asteadyspeed.Donotuse
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If the vehicle's Traction ControlSystem (TCS) or StabiliTrak systembegins to limit wheel spin whileusing cruise control, the cruisecontrol will automatically disengage.
SeeTr a c t i o n C o n t r o l / E l e c t r o n i cStability Control0197.Ifacollisionalert occurs when cruise control isactivated, cruise control isdisengaged. SeeForward CollisionAlert (FCA) System0204.Whenroad conditions allow you to safelyuse it again, the cruise control canbe turned back on.
If the brakes are applied, cruisecontrol disengages.
5:Press to turn the cruise controlsystem on and off. A white indicatorcomes on in the instrument clusterwhen cruise is turned on.
