192 Driving and Operating
{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.
Manual Mode
To u s e t h i s f e a t u r e , i f e q u i p p e d :
1. Move the shift lever fromD(Drive) rearward toM(Manual Mode).
While driving in manual mode,the transmission will remain inthe driver selected gear. Whencoming to a stop in the manualposition, the vehicle willautomatically shift into1(First) gear.

2. Press the + (plus) end of thebutton on the side of the shiftlever to upshift, or press the✓(minus) end of the button todownshift.
The Driver Information Center (DIC)in the instrument cluster will changefrom the currently displayedmessage to the letter M, for Manualposition, and a number indicatingthe requested gear.
While using manual mode, thetransmission will have firmer shiftingand sportier performance. You canuse this for sport driving or whenclimbing hills to stay in gear longeror to downshift for more power orengine braking.
The transmission will only allow youto shift into gears appropriate for thevehicle speed and enginerevolutions per minute (rpm):
.The transmission will notautomatically shift to the nexthigher gear if the vehicle speedor engine rpm is too low.
.The transmission will not allowshifting to the next lower gear ifthe vehicle speed or engine rpmis too high.
Manual Transmission
The vehicle may be equipped with a5-speed or 6-speed manualtransmission.
Caution
Shifting the vehicle initially into
any gear other than 1 (First) or
R(Reverse) can damage the
clutch. Shift the manual
transmission in the proper
sequence, and time the gear

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.

Driving and Operating 197
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.

242 Vehicle Care
Electrical System
Electrical System
Overload
The vehicle has fuses and circuitbreakers to protect against anelectrical system overload.
When the current electrical load istoo heavy, the circuit breaker opensand closes, protecting the circuituntil the current load returns tonormal or the problem is fixed. Thisgreatly reduces the chance of circuitoverload and fire caused byelectrical problems.
Fuses and circuit breakers protectpower devices 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,thesame amperage fuse can beborrowed. Choose some feature ofthe vehicle that is not needed to useand replace it as soon 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 and Circuit
Breakers
The wiring circuits in the vehicle areprotected from short circuits by acombination of fuses, circuitbreakers, and fusible thermal links.This greatly reduces the chance offires caused by electrical problems.
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.
