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 applyingthe 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 appropri-
ate 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
TheESP/TCS Indicator Lightlocated in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. TheESP/TCS Indicator Lightalso
flashes when TCS is active. If theESP/TCS Indicator
Lightbegins 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!
ESP (Electronic Stability Program) 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 acci-
dents, 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 jeopar-
dize the user’s safety or the safety of others.
The ESP system has 2 available operating modes in 2WD,
4WD Part Time, 4WD Full Time (Selec-Trac Only), and on
2WD vehicles. The system has a single operating mode in
4WD Low Range.

High Range (4WD Part Time, 4WD Full Time) or
2WD Models
ESP On
This is the normal operating mode for ESP in 2WD, 4WD
Part Time, 4WD Full Time (Selec-Trac Only), and on 2WD
vehicles. Whenever the vehicle is started or the transfer
case (if equipped) is shifted from 4WD low range or
neutral back to 4WD high range or 2WD, the ESP system
will be in this mode. This mode should be used for most
all driving situations. ESP should only be turned off for
specific reasons as noted below.
Partial Off
This mode is entered by momentarily depressing the “ESP
Control Switch” (located on top of the steering column).
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 ofESP function normally. This mode is intended to be used
if the vehicle is in deep snow, sand or gravel conditions
and more wheel spin than ESP would normally allow is
required to gain traction. To turn ESP on again, momen-
tarily depress the “ESP Control Switch”. This will restore
the normal “ESP 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 ESP switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is
overcome, turn ESP back on by momentarily depressing
the “ESP Control Switch”. This may be done while the
vehicle is in motion.
4WD Low Range
Partial Off
This is the normal operating mode for ESP in 4WD low
range. Whenever the vehicle is started in 4WD low range
or the transfer case (if equipped) is shifted from 2WD,
4WD high range, or neutral to 4WD low range, the ESP
system will be in this mode. In 4WD low range, ESP and
TCS, except for the “limited slip” feature described in the
TCS section, are turned off until the vehicle reaches a
speed of 30 mph (48 km/h). At 30 mph (48 km/h), thenormal ESP stability function returns but TCS remains
off. When the vehicle speed drops below 25 mph (40
km/h) the ESP system shuts off. ESP is off at low vehicle
speeds in 4WD low range so that it will not interfere with
off-road driving but ESP function returns to provide the
stability feature at speeds above 30 mph (48 km/h). The
“ESP/TCS Indicator Light” will always be illuminated in
4WD low range when ESP is off.
ESP/BAS Warning Lamp
The malfunction indicator lamp for the ESP is
combined with BAS. The “ESP/BAS Warning
Lamp” and the “ESP/TCS Indicator Light” in
the instrument cluster both come on when the
ignition switch is turned to the “ON” position. They
should go out with the engine running. If the “ESP/BAS
Warning Lamp” comes on continuously with the engine
running, a malfunction has been detected in either the
ESP or the BAS system. 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.
NOTE:
•TheESP/TCS Indicator Lightand theESP/BAS
Warning Lampcome 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.
OVERHEAD CONSOLE — IF EQUIPPED
The overhead console contains dome/reading lights, an
optional universal garage door opener (HomeLink), an
optional sunroof switch, and an Electronic Vehicle Infor-
mation Center (EVIC) that consists of the following:
•Compass/temperature display
•Trip information displays
•Vehicle information warning message displays
•Customer programmable features
Pressing the MENU button will change the displayed
programming features. Pressing the STEP button will
select the available choices. Pressing the C/T (Compass/
Temperature) button will return the display to the normal
compass/temperature display.

NOTE:Temperature accuracy can be effected from heat
soak. For best accuracy, the vehicle should be driven at a
speed greater than 20 mph (32 km/h) for several minutes.
Dome/Reading Lights
Located in the overhead console are two dome/reading
lights.The dome/reading lights illuminate when a door or the
swing gate is opened or when the interior lights are
turned on by rotating the dimmer control located on the
multi-function lever.
The reading lights are activated by pressing on the
recessed area of the corresponding lens.
NOTE:The dome/reading lights will remain on until
the switch is pressed a second time, so be sure they have
been turned off before leaving the vehicle.
