Engine exhaust contains carbon
monoxide (CO), which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
.The vehicle idles in areaswith poor ventilation(parking garages, tunnels,deep snow that may blockunderbody airflow or tailpipes).
.The exhaust smells orsounds strange or different.
.The exhaust system leaksdue to corrosion or damage.
.The vehicle exhaust systemhas been modified,damaged, or improperlyrepaired.
(Continued)
Warning (Continued)
.There are holes or openingsin the vehicle body fromdamage or aftermarketmodifications that are notcompletely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle:
.Drive it only with thewindows completely down.
.Have the vehicle repairedimmediately.
Never park the vehicle with the
engine running in an enclosed
area such as a garage or a
building that has no fresh air
ventilation.

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.

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

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.

Warning (Continued)
departing the lane on the side
where it has detected a lane
marking. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LDW in
bad weather conditions.
How the System Works
The LDW camera sensor is on thewindshield ahead of the rearviewmirror.
To t u r n L D W o n a n d o f f , p r e s s@on
the center console. The controlindicator will light when LDW is on.
When LDW is on,@is green if
LDW is available to warn of a lanedeparture. If the vehicle crosses adetected lane marking without using
the turn signal in that direction,@
changes to amber and flashes.Additionally, there will be threebeeps on the right or left, dependingon the lane departure direction.
When the System Does Not
Seem To Work Properly
The system may not detect lanes aswell when there are:
.Close vehicles ahead.
.Sudden lighting changes, suchas when driving through tunnels.
.Banked roads.
If the LDW system is not functioningproperly when lane markings areclearly visible, cleaning thewindshield may help.
LDW alerts may occur due to tarmarks, shadows, cracks in the road,temporary or construction lanemarkings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LDW off if theseconditions continue.
