How to use the engine block heater
Ensure the receptacle terminals are clean and dry prior to use. To clean
them, use a dry cloth.
Depending on the type of factory installed equipment, your engine block
heater system may consume anywhere between 400 watts or 1000 watts
of energy per hour. Your factory installed block heater system does not
have a thermostat; however, maximum temperature is attained after
approximately three hours of operation. Block heater operation longer
than three hours will not improve system performance and will
unnecessarily use additional electricity.
Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.
BRAKES
Your service brakes are self-adjusting. Refer to thescheduled
maintenance informationfor scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by an authorized dealer.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
WARNING:If you are driving down a long or steep hill, shift to
a lower gear. Do not apply your brakes continuously, as they may
overheat and become less effective.

Anti-lock brake system (ABS)
On ABS-equipped vehicles, a noise from the hydraulic pump motor and
pulsation in the pedal may be observed during ABS braking events. Pedal
pulsation coupled with noise while braking under panic conditions or on
loose gravel, bumps, wet or snowy roads is normal and indicates proper
functioning of the vehicle’s anti-lock brake system. The ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by an authorized dealer.
The ABS operates by detecting the onset of wheel lockup during brake
applications and compensates for this tendency. The wheels are
prevented from locking even when the brakes are firmly applied.
Using ABS
•In an emergency or when maximum efficiency from the four-wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain steering
control of your vehicle and, providing there is sufficient space, will
enable you to avoid obstacles and bring the vehicle to a controlled
stop.
•The anti-lock system does not always reduce stopping distance.
Always leave enough room between your vehicle and the vehicle in
front of you to stop.
•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
ABS warning lamp
The ABS warning lamp in the
instrument cluster momentarily
illuminates when the ignition is
turned on. If the light does not
illuminate momentarily at start up,
remains on or continues to flash, the ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. If your brake warning lamp illuminates, have your vehicle
serviced immediately.

WARNING:If a failure has been detected within the
AdvanceTrac
with RSC
system, thesliding caricon
will
illuminate steadily. Verify that the AdvanceTrac
with RSC
system is
not manually disabled (push the AdvanceTrac
with RSC
“Off “
button located on the center of the instrument panel). If thesliding
caricon
still illuminates steadily, have the system service by an
authorized dealer immediately. Operating your vehicle with
AdvanceTrac
with RSC
disabled could lead to an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
The AdvanceTrac
with RSC
system provides the following stability
enhancement features for certain driving situations:
•Traction Control (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
•Roll Stability Control™ (RSC
), which functions to help avoid a
vehicle roll-over.
The AdvanceTrac
with RSC
system automatically enables each time
the engine is started. All features of the AdvanceTrac
with RSC
system
(TCS, ESC, and RSC
are active and monitor the vehicle from start-up).
However, the system will only intervene if the driving situation requires
it.
The AdvanceTrac
with RSC

system includes an AdvanceTrac

with RSC
Offbuttononthe
center of the instrument panel, and
a “sliding car” icon
in the
instrument cluster. The “sliding car”
icon
in the instrument cluster will illuminate temporarily during
start-up as part of a normal system self-check, or during driving if a
driving situation causes the AdvanceTrac
with RSC
system to operate.
If the “sliding car” icon
illuminates steadily, verify that the
AdvanceTrac
with RSC
system is not manually disabled by pressing
the AdvanceTrac
with RSC
Offbutton located on the center of the
instrument panel. If the “sliding car” icon
remains steadily
illuminated, have the system serviced by an authorized dealer
immediately. The message center will also indicate a failure with the
AdvanceTrac
with RSC
system.

When AdvanceTrac
with RSC
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
with RSC
you may
experience the following:
•A slight deceleration of the vehicle
•The “sliding car”
indicator 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 (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 Traction Control events the “sliding car” icon
in the
instrument cluster will flash.
If the Traction Control system 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, Traction
Control 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, RSC
, 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

with RSC
section following.

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 Electronic Stability Control events the “sliding car” icon
in the
instrument cluster will flash.
Certain adverse driving maneuvers may activate the Electronic Stability
Control 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).
The Electronic Stability Control system may be deactivated in certain
situations. See theSwitching Off AdvanceTrac
with RSC
section
following.
Roll Stability Control™ (RSC
)
Roll Stability Control (RSC
) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSC
operates by detecting the
vehicle’s roll motion and the rate at which it changes and by applying the
brakes to one or more wheels individually.
During an event that activates the Roll Stability Control™ (RSC
)the
“sliding car” icon
in the instrument cluster will flash.
Certain adverse driving maneuvers may activate the Roll Stability Control
system, which include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle

Owners Guide, 1st Printing
USA(fus)
Driving
263

To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
•Do not operate the vehicle with the power steering pump fluid level
below the MIN mark on the reservoir.
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components
Variable assist steering
Your vehicle is equipped with variable assist power steering. At low
engine RPM, steering assist will adjust to reduce efforts and improve low
speed maneuverability. At high engine RPM, the assist will adjust to
improve steering feel at high speeds.
If the amount of effort required to steer your vehicle changes while
driving at a constant engine RPM, have the power steering system
checked by your authorized dealer.
AIR SUSPENSION SYSTEM
The air suspension system is designed to improve ride, handling and
general vehicle performance during:
•Certain road conditions

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. See your authorized dealer.
Driving with a 6–speed automatic transmission
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:
•Depress the brake pedal
•Start the engine
•Move the gearshift lever into the desired gear. If your vehicle is
equipped with a floor-shift transmission, press the gearshift lever
release button (on the front of the lever) while shifting into the
desired gear.

The TOW HAUL indicator light will
illuminate in the instrument cluster.
Tow/Haul delays upshifts to reduce frequency of transmission shifting.
Tow/Haul also provides engine braking in all forward gears when the
transmission is in the D (Overdrive) position; this engine braking will
slow the vehicle and assist the driver in controlling the vehicle when
descending a grade. Depending on driving conditions and load
conditions, the transmission may downshift, slow the vehicle and control
the vehicle speed when descending a hill, without the accelerator pedal
being pressed. The amount of downshift braking provided will vary based
upon the amount the brake pedal is depressed.
To deactivate the Tow/Haul feature and return to normal driving mode,
press the button on the end of the gearshift lever. The TOW HAUL light
will no longer be illuminated.
When you shut-off and restart the engine, the transmission will
automatically return to normal D (Overdrive) mode (Tow/Haul OFF).
WARNING:Do not use the Tow/Haul feature when driving in icy
or slippery conditions as the increased engine braking can cause
the rear wheels to slide and the vehicle to swing around with the
possible loss of vehicle control.
3 (Third)
Transmission operates in third gear only.
Used for improved traction on slippery roads. Selecting 3 (Third)
provides engine braking.
2 (Second)
Transmission operates in 2nd gear only.
Use 2 (Second) to start-up on slippery roads or to provide additional
engine braking on downgrades.
1 (First)
•Transmission operates in 1st gear only.
•Provides maximum engine braking.
•Allows upshifts by moving gearshift lever.
•Will not downshift into 1 (First) at high speeds; allows for 1 (First)
when vehicle reaches slower speeds.

Forced downshifts
•Allowed in D (Drive) only.
•Depress the accelerator to the floor.
•Allows transmission to select an appropriate gear.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
If your vehicle is equipped with AdvanceTrac
with RSC, it may be
beneficial to turn the system off so the wheels are allowed to spin.
FORWARD AND REVERSE SENSING SYSTEMS
The forward and reverse sensing system will warn the driver of obstacles
within a certain range of the front and rear bumpers. The front sensors
will be active when the gearshift is in any position other than P (Park)
or N (Neutral) and the vehicle speed is below 8 mph (13 km/h). The
rear sensors will only be active when the gearshift is in R (Reverse).
