WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer as soon as possible.
ADVANCETRACSTABILITY ENHANCEMENT SYSTEM
Your vehicle is equipped with the AdvanceTrac
system. The
AdvanceTrac
system provides the following stability enhancement
features for certain driving situations:
•Traction control system (TCS), which functions to help avoid
drive-wheel spin and loss of traction.
•Electronic stability control (ESC), which functions to help avoid skids
or lateral slides
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTrac
system. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac

system. Install any aftermarket stereo loudspeaker as far as possible
from the front center console, the tunnel, and the front seats in order
to minimize the risk of interfering with the AdvanceTrac
sensors.
Reducing the effectiveness of the AdvanceTrac
system could lead to
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.

WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTrac
system is an indication that at least
some of the tires have exceeded their ability to grip the road; this
could reduce the operator’s ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle rollover, personal injury
and death. If your AdvanceTrac
system activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTrac
system, the stability control light and the stability
control off light will illuminate steadily. If the stability control light and
the stability control off light illuminate steadily, contact your
authorized dealer as soon as possible to have the system serviced
immediately. Operating your vehicle with AdvanceTrac
disabled could
lead to an increased risk of loss of vehicle control, vehicle rollover,
personal injury and death.
The AdvanceTrac
system automatically enables each time the engine is
started. All features of the AdvanceTrac
system (TCS and ESC) are
active and monitor the vehicle from start-up. However, the system will
only intervene if the driving situation requires it.
The AdvanceTrac
system includes
a stability control button on the
center console, a stability control
light and a stability control off light
in the instrument cluster. Both the
stability control light and the
stability control off light in the
instrument cluster will illuminate
temporarily during start-up as part of a normal system self-check. The
stability control light may illuminate (flash) during certain driving
situations which cause the AdvanceTrac
system to operate. If the
stability control light and the stability control off light illuminate steadily,
contact your authorized dealer as soon as possible to have the system
serviced immediately. If equipped with a message center, the vehicle will
also indicate a failure with the AdvanceTrac
system.

When AdvanceTrac
performs a normal system self-check, some drivers
may notice a slight movement of the brake, and/or a rumble, grunting, or
grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTrac
you may experience
the following:
•A slight deceleration of the vehicle
•The stability control light will flash.
•A vibration in the pedal when your foot is on the brake pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
Traction control system (TCS)
Traction control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem, engine traction control and brake traction
control. Engine traction control works to limit drive-wheel spin by
momentarily reducing engine power. Brake traction control works to limit
wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction control is most active at low speeds.
During TCS events, the stability control light in the instrument cluster
will flash.
If the TCS is activated excessively in a short period of time, the braking
portion of the system may become temporarily disabled to allow the
brakes to cool down. In this situation, the TCS will use only engine
power reduction or transfer to help control the wheels from
over-spinning. When the brakes have cooled down, the system will regain
all features. Anti-lock braking, and ESC are not affected by this condition
and will continue to function during the cool-down period.
The engine traction control and brake traction control system may be
deactivated in certain situations. See theSwitching off AdvanceTrac

section below.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching the TCS off. This may allow excess wheel spin to
“dig” the vehicle out and enable a successful “rocking” maneuver.

Electronic stability control (ESC)
Electronic stability control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.
During ESC events, the stability control light in the instrument cluster
will flash.
Certain adverse driving maneuvers may activate the ESC system, which
include but are not limited to:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Driving over a patch of ice or other slippery surfaces
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter).
Switching off AdvanceTrac

If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTrac
system may be
beneficial because the wheels are allowed to spin. This will restore full
engine power and will enhance momentum through the obstacle.
The stability control button can be
used to enable unique
AdvanceTrac
modes.
Full features of the AdvanceTrac

system can be restored by pressing
the stability control button again or
by turning off and restarting the
engine.

When features of the AdvanceTrac

system are off, the stability control
off light will illuminate steadily.
Pressing the stability control button
again will turn off the stability
control off light.
In R (Reverse), ABS and the engine traction control and brake traction
control features will continue to function; however, ESC is disabled.

The AdvanceTrac
system provides an available sport mode on some
models. This can be selected utilizing the stability off button as shown in
the table above.
Sport mode is not intended for use on public roadways as this mode
provides less AdvanceTrac
system intervention than when the default
ESC and traction control systems are on. Sport mode will allow more
spirited driving while the AdvanceTrac
system is still enabled.

STEERING
Your vehicle is equipped with an electric power-assisted steering (EPAS)
system. There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Under extreme usage conditions, the steering effort may
increase. This occurs to prevent overheating and permanent damage to
your steering system. If this should occur, you will neither lose the ability
to steer the vehicle manually nor will it cause permanent damage.
Typical steering and driving maneuvers will allow the system to cool and
steering assist will return to normal.
If the steering wanders or pulls, check for:
•an improperly inflated tire.
•uneven tire wear.
•loose or worn suspension components.
•loose or worn steering components.
•improper steering alignment.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
TRACTION-LOK™ AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok™ axle functions like a standard rear axle.
Extended use of other than the manufacturer’s specified size tires on a
Traction-Lok™ rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
BRAKE-SHIFT INTERLOCK
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless the brake pedal is pressed.

If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal pressed:
1. Apply the parking brake.
2. Using a flat head screwdriver or
similar tool, remove the cap.
3. Locate the access hole at the
front of the area under the cover.
4. Insert the screwdriver or similar
tool into the hole and press and
hold the lever forward while pulling
the gearshift lever out of the P
(Park) position and into the N
(Neutral) position.
5. Reinstall the cap.
6. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brake lamps are not
operating properly. Refer toFuses and relaysin theRoadside
Emergencieschapter.
WARNING:Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. Contact your authorized dealer as soon as possible to
have the system serviced immediately.

AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Driving with a 6–speed automatic transmission
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
This vehicle is equipped with an adaptive transmission shift strategy. The
adaptive transmission shift strategy offers the optimal transmission
operation and shift quality. When the engine is turned off, the shift data
which includes the adaptive information will be stored automatically in
the powertrain control module (PCM). If the battery is disconnected for
any reason, the stored information from the last time the key was turned
to off will be read. This way, no information will be lost with any battery
removal or battery disconnect.
P (Park)
This position locks the transmission
and prevents the rear wheels from
turning.
To put your vehicle in gear:
1. Start the engine.
2. Press the brake pedal.
3. Move the gearshift lever into the
desired gear.
To put your vehicle in P (Park):
1. Come to a complete stop.
2. Move the gearshift lever and securely latch it in P (Park).
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R
(Reverse).
