required. However, the conventional brake system will
continue to operate normally if the “Brake Warning
Light” is not on.
If the “ABS Warning Light” is on, the brake system
should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “ABS Warning Light”
does not come on when the ignition switch is turned to
the ON position, have the bulb repaired as soon as
possible.
If both the “Brake Warning Light” and the “ABS Warning
Light” remain on, the ABS and Electronic Brake Force
Distribution (EBD) systems are not functioning. Immedi-
ate repair to the ABS is required.
When the vehicle is driven over 7 mph (11 km/h), you may
also hear a slight clicking sound as well as some related
motor noises. These noises are the system performing its
self-check cycle to ensure that the ABS working properly.This self-check occurs each time the vehicle is started and
accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You may also experience the following when the brake
system goes into anti-lock mode:
•
the ABS motor running (it may continue to run for a
short time after the stop)
• the clicking sound of solenoid valves
• brake pedal pulsations
• a slight drop or fall away of the brake pedal at the end
of the stop
These are all normal characteristics of ABS.

Hill Descent Control (HDC) – If Equipped
This system maintains vehicle speed while descending
hills during off-road driving situations. HDC will auto-
matically apply the brakes to control downhill speed to
between 4 mph (7 km/h) and 6 mph (9 km/h) depending
on terrain. The system is activated by placing the vehicle
in “Off-Road” mode and placing the shift lever in LOW
or REVERSE. Refer to “Safe Off-Road Driving” in “Start-
ing and Operating” for further information.When HDC is properly enabled, the “Hill
Decent Control Light” in the instrument cluster
will be illuminated.
HDC has the capability to sense terrain and will only
activate when the vehicle is descending a hill. It will not
activate on level ground. If desired, HDC can be fully
deactivated by putting the vehicle into ESC “Full Off”
mode. This is done by pressing and holding the “ESC Off” button for five seconds. Refer to “Electronic Stability
Control (ESC)” in this section of the manual.
HDC operation can be overridden with brake application
to slow the vehicle down below the HDC control speed.
Conversely, if more speed is desired during HDC control,
the accelerator pedal will increase vehicle speed like
normal. When either the brake or the accelerator is
released, HDC will control the vehicle back to the origi-
nal set speed.
HDC is only intended for low speed off-road driving. At
vehicle speeds above 31 mph (50 km/h) HDC will no
longer function. If the “HDC Indicator Light” begins to
flash this indicates that the brakes are getting too hot and
the vehicle should be stopped to allow the brakes to cool.
5
STARTING AND OPERATING 349

WARNING!
HDC is only intended to assist the driver in control-
ling vehicle speed when descending hills. The driver
must remain attentive to the driving conditions and
is responsible for maintaining a safe vehicle speed.
Hill Start Assist (HSA) – Manual Transmission
Only
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes their foot off of the
brake pedal. If the driver does not apply the throttle
during this short period of time, the system will release
brake pressure and the vehicle will roll down the hill. The
system will release brake pressure in proportion to
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped.
• Vehicle must be on a 7% grade or greater hill.
• Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills (i.e., less than
8%), with a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight rolling
may occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
350 STARTING AND OPERATING

Disabling/Enabling HSA
If you wish to turn on or off the HSA system, it can be
done using the Customer Programmable Features in the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
For vehicles not equipped with the EVIC, perform the
following steps:
NOTE:You must complete Steps 1 through 8 within
90 seconds.
1. Center the steering wheel (front wheels pointing straight forward).
2. Shift the transmission into NEUTRAL.
3. Apply the parking brake.
4. Start the engine. 5. Release the clutch pedal (if equipped).
6. Rotate the steering wheel one-half turn to the left.
7. Press the “ESC Off” switch (located in the lower
switch bank below the climate controls) four times
within 20 seconds. The “ESC Activation/Malfunction
Indicator Light” should turn on and turn off two
times.
8. Rotate the steering wheel back to center and then an additional half-turn to the right.
9. Turn the ignition switch to the OFF position and then back to the ON position. If the sequence was com-
pleted properly, the “ESC Activation/Malfunction
Indicator Light” will blink several times to confirm
HSA is disabled.
10. Repeat these steps if you want to return this feature to it’s previous setting.

STARTING AND OPERATING 351

ESC Operating Modes
The ESC system has three available operating modes for
four–wheel drive equipped vehicles and two available
operating modes for two–wheel drive equipped vehicles.
Full On (Four-Wheel Drive Models) Or On (Two-Wheel
Drive Models)
This is the normal operating mode for ESC. Whenever
the vehicle is started the ESC system will be in this “On”
mode. This mode should be used for most driving
situations. ESC should only be turned to “Partial Off” or
“ESC Off” for specific reasons as noted below.
Partial Off (Four-Wheel Drive Models) Or On
(Two-Wheel Drive Models)
This mode is entered by momentarily pressing the “ESC
Off” switch. When in “Partial Off” mode, the TCS portion
of ESC, except for the “limited slip” feature described
in the TCS section, has been disabled and the “ESCActivation/Malfunction Indicator Light” will be illumi-
nated. All other stability features of ESC function nor-
mally. This mode is intended to be used if the vehicle is
in deep snow, sand or gravel conditions and more wheel
spin than ESC would normally allow is required to gain
traction.
To turn ESC on again, momentarily press the “ESC Off”
switch. This will restore the normal “ESC On” mode of
operation.
NOTE:
To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the “ESC Off” switch. Once the situa-
tion requiring ESC to be switched to the “Partial Off”
mode is overcome, turn ESC back on by momentarily
pressing the “ESC Off” switch. This may be done while
the vehicle is in motion.
5
STARTING AND OPERATING 353

WARNING!
When in “Partial Off” mode, the TCS functionality of
ESC (except for the limited slip feature described in
the TCS section) has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Par-
tial Off” mode, the engine power reduction of TCS is
disabled, and the enhanced vehicle stability offered
by the ECS system is reduced.
Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or off-road use
when ESC stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
pressing and holding the “ESC Off” switch for five
seconds when the vehicle is stopped and the engine is
running. After five seconds, the “ESC Activation/
Malfunction Indicator Light” will illuminate and the “ESC OFF” message will appear in the odometer. Press
and release the Trip Odometer button located on the
instrument cluster to clear this message.
In this mode, ESC and TCS, except for the “limited slip”
feature described in the TCS section, are turned off until
the vehicle reaches a speed of 35 mph (56 km/h). At
35 mph (56 km/h) the system returns to “Partial Off”
mode, as described above. TCS remains off. When the
vehicle speed drops below 30 mph (48 km/h) the ESC
system shuts off. ESC is deactivated at low vehicle speeds
so that it will not interfere with off-road driving however,
ESC function returns to provide the stability feature at
speeds above 35 mph (56 km/h). The “ESC Activation/
Malfunction Indicator Light” will always be illuminated
when ESC is off.
To turn ESC on again, momentarily press the “ESC Off”
switch. This will restore the “ESC On” mode of operation.
354 STARTING AND OPERATING

NOTE:The “ESC OFF” message will display and an
audible chime will sound when the shift lever is placed
into the PARK position from any other position, and then
moved out of the PARK position. This will occur even if
the message was previously cleared.
WARNING!
With the ESC in the Full Offmode, the engine
torque reduction and stability features are disabled.
Therefore, the enhanced vehicle stability offered by
ESP is unavailable. In an emergency evasive maneu-
ver, the ESC system will not engage to assist in
maintaining stability. “ESC Off” mode is intended
for off-highway or off-road use 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 turned to the ON
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
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.
5
STARTING AND OPERATING 355

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 Activation/Malfunction Indicator Light”
and the “ESC OFF Indicator Light” come on momen-
tarily each time the ignition switch is turned ON. •
Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
• 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 off.
