under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lockup and
help avoid skidding on slippery surfaces during braking.
NOTE:ABS improves steering control of the vehicle
during hard braking maneuvers.

WARNING!
²Anti-lock system (ABS) cannot prevent the natural
laws of physics from acting on the vehicle, nor can
it increase braking or steering efficiency beyond
that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
²The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
²The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.
ELECTRONIC BRAKE CONTROL SYSTEM ±
ABS/TCS/BAS/ERM/HDC/ESP
Your vehicle may be equipped with an optional ad-
vanced electronic brake control system that includes
Anti-Lock Brake System (ABS), Traction Control System
(TCS), Brake Assist System ( BAS), Electronic Roll Miti-
gation (ERM), Hill Descent Control (HDC) and Electronic
Stability Program (ESP). All systems work together to
enhance vehicle stability and control in various driving
conditions and are commonly referred to as ESP.
Anti-Lock Brake System ± ABS
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lockup and
help avoid skidding on slippery surfaces during braking.
Refer to ªAnti-Lock Brake Systemº in this Section of the
manual for more information about ABS.

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in
either the ªPartial Offº or ªESP Offº modes. Refer to
ªElectronic Stability Program (ESP)º in this Section of this
manual.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle's braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence. Do not
reduce brake pedal pressure unless braking is no longer
desired. Once the brake pedal is released, the BAS is
deactivated.

WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM can not
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects
or other vehicles. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ERM equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopar-
dize the user's safety or the safety of others.
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) dependingon terrain. The system is activated by placing the vehicle
in ªOff-Roadº mode and placing the gear selector in
ªLowº or ªReverse.º
When the system is available, the HDC indica-
tor lamp will be illuminated solid.
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 in by putting the vehicle into ESP ªfull offº
mode (refer to the Electronic Stability Program (ESP)
located in the ªElectronic Brake Controlº section of this
manual). This is done by pressing and holding the ESP
OFF button for 5 seconds.
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,
140 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 lamp begins to
flash it means that the brakes are getting too hot and the
vehicle should be stopped to allow the brakes to cool.
ESP (Electronic Stability Program)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path. ESP uses sensors in the vehicle to determine
the vehicle path intended by the driver and compares itto the actual path of the vehicle. When the actual path
does not match the intended path, ESP applies the brake
of the appropriate wheel to assist in counteracting the
oversteer or understeer condition
²Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
²Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESP/TCS Indicator Light
The ªESP/TCS Indicator Lightº located in the instrument
cluster, starts to flash as soon as the tires lose traction and
the ESP system becomes active. The ªESP/TCS Indicator
Lightº also flashes when TCS is active. If the ªESP/TCS
Indicator Lightº begins to flash during acceleration, 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.

WARNING!
²Electronic Stability Program (ESP) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions.
²ESP cannot prevent accidents, including those
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. Only a
safe, attentive, and skillful driver can prevent
accidents.
²The capabilities of an ESP-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.
ESP 2WD Operating Modes
All 2WD vehicles can choose the following ESP operating
modes:
ESP ON
This is the normal operating mode for ESP. Whenever the
vehicle is started the ESP system will be in this mode.
This mode should be used for almost all driving situa-
tions. ESP should only be turned to ªPartial Offº or ªESP
Offº for specific reasons as noted below.
PARTIAL ESP
This mode is entered by momentarily depressing the
ªESP Control Switchº. When in ªPartial Offº mode, the
TCS portion of ESP, except for the ªlimited slipº feature
described in the TCS section, has been disabled and the
ªESP/TCS Indicator Lightº will be illuminated. All other
stability features of ESP function normally, with the
exception of engine power reduction. This mode is
intended to be used if the vehicle is in deep snow, sand or
142 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

gravel conditions and more wheel spin than ESP would
normally allow is required to gain traction.
To turn ESP on again, momentarily depress the ªESP
Control Switchº. This will restore the normal ªESP Onº
mode of operation.
WARNING!
In the Partial ESP mode, the engine torque reduction
and stability features are desensitized. Therefore, the
enhanced vehicle stability offered by ESP is
unavailable.
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 ªPartial Offº
mode by pressing the ESP switch. Once the situation
requiring ESP to be switched to the ªPartial Offº mode isovercome, turn ESP back on by momentarily depressing
the ªESP Control Switchº. This may be done while the
vehicle is in motion.
ESP 4WD Operating Modes
In addition to ESP ON and Partial ESP (described above
in ªESP 2WD Operating Modesº), all 4WD equipped
vehicles can also choose the following ESP operating
mode:
ESP OFF
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
depressing and holding the ªESP Control Switchº for 5
seconds when the vehicle is stopped and the engine is
running. After 5 seconds, the ªESP/TCS Indicator Lightº
will illuminate and the ªESP Offº 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, ESP and TCS, except for the ªlimited slipº
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 normal ESP stability function returns
with the exception of engine power reduction. TCS
remains off. When the vehicle speed drops below 30 mph
(48 km/h) the ESP system shuts off. ESP is off at low
vehicle speeds so that it will not interfere with off-road
driving but ESP function returns to provide the stability
feature at speeds above 35 mph (56 km/h). The ªESP/
TCS Indicator Lightº will always be illuminated when
ESP is off.
To turn ESP on again, momentarily depress the
ªESP Control Switchº. This will restore the
normal ªESP Onº mode of operation.ESP/BAS Warning Light and ESP/TCS Indicator
Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow ªESP/BAS Warning
Lampº and the yellow ªESP/TCS Indicator Lightº in the
instrument cluster both come on when the ignition
switch is turned to the ªONº position. They should both
go out with the engine running. If the ªESP/BAS Warn-
ing Lampº comes on continuously with the engine
running, a malfunction has been detected in either the
ESP or BAS system, or both. If this light remains on after
several ignition cycles, and the vehicle has been driven
several miles at speeds greater than 30 mph (48 km/h),
see your authorized dealer as soon as possible to have the
problem diagnosed and corrected.

WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP is unavailable. In an emer-
gency evasive maneuver, the ESP system will not
engage to assist in maintaining stability. ªESP Offº
mode is intended for off-highway or off-road use,
only.NOTE:
²The ªESP Indicator Lightº and the ªESP/BAS Warning
Lightº come on momentarily each time the ignition
switch is turned ON.
²Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
²The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.

CAUTION!
²To prevent damage to the roof of your vehicle, DO NOT
carry any loads on the roof rack without cross rails
installed. The load should be secured and placed on top of
the cross rails, not directly on the roof. If it is necessary to
place the load on the roof, place a blanket or some other
protection between the load and the roof surface.
²To avoid damage to the roof rack and vehicle, do not
exceed the rated load capacity of your cross rail system or
the roof rack system maximum load capacity of 150 lbs (68
kg). Always distribute heavy loads as evenly as possible
and secure the load appropriately.
²Long loads which extend over the windshield, such as
wood panels or surfboards, should be secured to both the
front and rear of the vehicle.
²Travel at reduced speeds and turn corners carefully when
carrying large or heavy loads on the roof rack. Wind forces,
due to natural causes or nearby truck traffic, can add
sudden upward loads. This is especially true on large flat
loads and may result in damage to the cargo or your
vehicle.
WARNING!
Cargo must be securely tied before driving your
vehicle. Improperly secured loads can fly off the
vehicle, particularly at high speeds, resulting in per-
sonal injury or property damage. Follow the roof rack
ªCautionsº when carrying cargo on your roof rack.
