ERM (Electronic Rollover Mitigation)
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 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
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!
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.

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), the
normal 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 Light and the ESP/BAS
Warning Lamp 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.
ELECTRONIC SPEED CONTROL
When engaged, this device takes over accelerator opera-
tions beginning at speeds of approximately 30 mph (48
km/h). The controls are mounted on the steering wheel
and consist of ON·OFF, SET, RES·ACCEL, CANCEL, and
DECEL controls.To Activate
Press and release the ON·OFF button to turn the system
on. To turn the system off, press the ON·OFF button
again. The system should be turned off when not in use.
The CRUISE indicator light in the instrument cluster
illuminates when the system is on.

To Accelerate for Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE: When driving uphill, at elevations above 2,000
ft. (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. (If the vehicle speed drops below 35 mph (56
km/h), the Speed Control will automatically disengage).
If this happens, you can push down on the accelerator
pedal to maintain the desired speed.
A full throttle (high RPM) acceleration, while the system
is engaged, will cause the system to disengage.
Vehicles may exhibit several 4-3 downshifts under the
above conditions. To reduce the frequency of the down-
shifts and to improve vehicle performance, it is advisable
to lock out overdrive. Press the O/D OFF button on the
right side of the shift lever.WARNING!
Leaving the Speed Control on when not in use is
dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always turn the system
off when you are not using it.

inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale. (See page 268 for more infor-
mation.)
6. 4LO Mode Indicator Light — If Equipped This light alerts the driver that the vehicle is in
the 4 LO four–wheel drive mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. (See page 234 for more infor-
mation.) 7. Fog Light Indicator Light — If Equipped
This light shows when the front fog lights are on.
8. Malfunction Indicator Light This light is part of an onboard diagnostic system
called OBD II which monitors engine and auto-
matic transmission control systems. This light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the ignition key from OFF to ON, have the
condition checked promptly.
Certain conditions such has a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving cycles. In most
situations, the vehicle will drive normally and will not
require towing.
