ANTI-LOCK BRAKE SYSTEM (ABS) – IF
EQUIPPED
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.
NOTE:ABS improves steering control of the vehicle
during hard braking maneuvers.
WARNING!
•Anti-lock system (ABS) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor
can it increase braking or steering efficiency be-
yond that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
•The 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.
•The 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/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) 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 lock-up and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” 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 “Partial Off” or “ESP Off” modes. Refer to
“Electronic Stability Program (ESP)” in this Section of this
manual.

Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicles speed
are sufficient to potentially cause wheel lift, it applies the
appropriate brake and may reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It can not
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.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.

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 it
to 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
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESP/TCS Indicator Light
The “ESP/TCS Indicator Light” located in the instrument
cluster, starts to flash as soon as the tires lose traction and
the ESP system becomes active. The “ESP/TCS Indicator
Light” also flashes when TCS is active. If the “ESP/TCS
Indicator Light” 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!
•Electronic 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.
•ESP 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.
•The 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 “Partial Off” or “ESP
Off” for specific reasons as noted below.
PARTIAL ESP
This mode is entered by momentarily depressing the
“ESP Control Switch”. When in “Partial Off” mode, the
TCS portion of ESP, except for the “limited slip” feature
described in the TCS section, has been disabled and the
“ESP/TCS Indicator Light” 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
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 143

gravel conditions and more wheel spin than ESP would
normally allow is required to gain traction.
To turn ESP on again, momentarily depress the “ESP
Control Switch”. This will restore the normal “ESP On”
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 “Partial Off”
mode by pressing the ESP switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode isovercome, turn ESP back on by momentarily depressing
the “ESP Control Switch”. 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 “ESP 2WD Operating Modes”), 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 “ESP Control Switch” for 5
seconds when the vehicle is stopped and the engine is
running. After 5 seconds, the “ESP/TCS Indicator Light”
will illuminate and the “ESP Off” message will appear in
the odometer. Press and release the trip odometer button
located on the instrument cluster to clear this message.
144 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

In this mode, ESP 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 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 “ESP/
TCS Indicator Light” will always be illuminated when
ESP is off.
To turn ESP on again, momentarily depress the
“ESP Control Switch”. This will restore the
normal “ESP On” 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 “ESP/BAS Warning
Lamp” and the yellow “ESP/TCS Indicator Light” in the
instrument cluster both come on when the ignition
switch is turned to the “ON” position. They should both
go out with the engine running. If the “ESP/BAS Warn-
ing Lamp” 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 stabil-
ity offered by ESP is unavailable. In an emergency
evasive maneuver, the ESP system will not engage to
assist in maintaining stability. “ESP Off” mode is
intended for off-highway or off-road use, only.
NOTE:
•The “ESP Indicator Light” and the “ESP/BAS Warning
Light” come on momentarily each time the ignition
switch is turned ON.
•Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
•The 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.
