traction with seamless steering feel to provide im-
proved handling and acceleration over two-wheel
drive vehicles. The active suspension system will be in
Touring Mode.
•Track– Track road calibration for use on high traction
surfaces. Driveline is maximized for traction. Some
binding may be felt on less forgiving surfaces. The
electronic brake controls are set to Partial OFF to limit
traction control management of throttle and wheel
spin.
•The transmission will be in SPORT shift mode and
provide a more aggressive shifting pattern. Refer to
“Paddle Shift Mode” in “Starting And Operating”
for further information.
•The customer has the option of going to FULL OFF
with no interaction from the ESC System. The active
suspension system will be in Full Firm mode.
•This feature will reset to AUTO on an ignition cycle.•To w– Use this mode for towing. Vehicle suspension
will go to Firm mode. Trailer sway control is enabled
in the ESC system. The terrain switch will remain in
this position through an ignition cycle until the cus-
tomer cycles into another position. This feature will
reset to AUTO upon an ignition cycle.
Active Damping System
This vehicle is equipped with an electronic controlled
damping system. This system reduces body roll and pitch
in many driving situations including cornering, accelera-
tion and braking. There are 3 modes:
•Touring Mode(Available in terrain positions AUTO
and SNOW) — Used during highway speeds where a
touring suspension feel is desired.
•Firm Mode(Available in terrain positions SPORT and
TOW) — Provides a firm suspension for better han-
dling.
418 STARTING AND OPERATING

FUEL SAVER TECHNOLOGY — IF EQUIPPED
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the shift lever in the
PARK position.
The foot operated parking brake is located below the
lower left corner of the instrument panel. To apply the
park brake, firmly push the park brake pedal fully. To
release the parking brake, press the park brake pedal a
second time and let your foot up as you feel the brake
disengage.When the parking brake is applied with the ignition
switch in the ON position, the “Brake” Warning Light in
the instrument cluster will illuminate.

STARTING AND OPERATING 423

NOTE:
•When the parking brake is applied and the transmis-
sion is placed in gear, the “Brake” Warning Light will
flash. If vehicle speed is detected, a chime will sound
to alert the driver. Fully release the parking brake
before attempting to move the vehicle.
•This light only shows that the parking brake is ap-
plied. It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking
brake before placing the shift lever in PARK, otherwise
the load on the transmission locking mechanism may
make it difficult to move the shift lever out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
•When leaving the vehicle, always remove the Key
Fob from the ignition and lock your vehicle.
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the shift lever.
•When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, re-
move the Key Fob from the vehicle and lock the
vehicle.

424 STARTING AND OPERATING

WARNING!(Continued)
•Do not leave the Key Fob in or near the vehicle or
in a location accessible to children, and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go™ in the ACC or ON/RUN
mode. A child could operate power windows, other
controls, or move the vehicle.
•Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to brake
failure and a collision.
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the “Brake” Warning Light remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems loses
normal capability, the remaining system will still func-
tion. However, there will be some loss of overall braking
effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light.”
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the

stability.ESC Offmode is intended for off-highway
or off-road use only.
NOTE:When the ESC is switched OFF, a feature of the
system remains active. This feature controls wheel spin
across an axle quite similarly to a limited slip differential.
If one wheel on an axle is spinning faster than the other,
the system will apply the brake of the spinning wheel
and allow more engine torque to be applied to the wheel
that is not spinning. To improve the vehicle’s traction
when driving with tire chains, or when starting off in
deep snow, sand, or gravel, it may be desirable to switch
to the “Partial Off” mode by momentarily pressing the
“ESC Off” switch.
WARNING!
With the ESC switched OFF, the enhanced vehicle
stability offered by ESC is unavailable. In an emer-
gency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. The “Full
Off” ESC mode is intended for off-highway or off-
road only.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is cycled to the ON/
RUN position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
5
STARTING AND OPERATING 433

light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch is placed in the
ON/RUN position.
•Each time the ignition is cycled to the ON/RUN
position, the ESC system will be ON even if it was
cycled off previously, except for when the vehicle is
started while in 4L Range.
•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is partially
off or full off.
434 STARTING AND OPERATING

NOTE:When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
The system will automatically update, the graphic dis-
play of the pressure value(s) will return to the original
color and the Tire Pressure Monitoring Telltale Light will
extinguish once the updated tire pressure(s) have been
received. The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this infor-
mation.
SERVICE TPM SYSTEM Warning
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The DID will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with “- -“in place of the pressure value(s), indicating which Tire
Pressure Monitoring Sensor(s) is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, theSERVICE TPM SYSTEM
message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
468 STARTING AND OPERATING

5. Using wheels/tires not equipped with TPM sensors.
The DID will also display aSERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault is detected possibly related to an incorrect sensor
location fault. In this case, theSERVICE TPM SYSTEM
message is then followed by a graphic display, with
pressure values still shown. This indicates the pressure
values are still being received from the TPM Sensors but
they may not be located in the correct vehicle position.
However, the system still needs to be serviced as long as
theSERVICE TPM SYSTEMmessage exists.NOTE:
•There is no tire pressure monitoring sensor in the spare
tire. The TPMS will not be able to monitor the tire
pressure. If you install the spare tire in place of a road
tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition switch cycle, the Tire
Pressure Monitoring Telltale Light will remain ON, a
chime will sound, and the DID will still display a
different color pressure value in the graphic display.
AnInflate to XXXmessage will still be displayed.
•After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid. In addition, the DID will display
a “SERVICE TPM SYSTEMmessage for a minimum of
five seconds and then display dashes (- -) in place of
the pressure value. For each subsequent ignition
switch cycle, a chime will sound, the Tire Pressure
