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 vehicle’s speed
are sufficient to potentially cause wheel lift, it then
applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers. ERM can only reduce the
chance of wheel lift occurring during severe or evasive
driving maneuvers. It cannot prevent wheel lift due to
other factors, such as road conditions, leaving the road-
way, or striking objects or other vehicles.
NOTE:ERM is disabled anytime the ESC is in “Full Off”
mode. Refer to Electronic Stability Control (ESC) for a
complete explanation of the available ESC modes.WARNING!
Many factors, such as vehicle loading, road condi-
tions, and driving conditions, influence the chance
that wheel lift or rollover may occur. Electronic Roll
Mitigation (ERM) cannot prevent all wheel lift or
rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous manner,
which could jeopardize the user’s safety or the safety
of others.
Hill Start Assist (HSA)
The HSA system is designed to help the driver accelerate
the vehicle from a complete stop while on an incline. If
the driver releases the brake while stopped on an incline,
HSA will continue to hold the brake pressure for a short
period. If the driver does not apply the throttle before this

WARNING!
•If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there may
not be enough brake pressure to hold both the
vehicle and the trailer on a hill when the brake
pedal is released. In order to avoid rolling down
an incline while resuming acceleration, manually
activate the trailer brake or apply more vehicle
brake pressure prior to releasing the brake pedal.
•HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.
•Failure to follow these warnings can result in a
collision or serious personal injury.
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
For vehicles equipped with the Electronic Vehicle Infor-
mation Center (EVIC), refer to “Hill Start Assist,” under
Personal Settings (Customer Programmable Features),”
under “Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further in-
formation.
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 PARK.

3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel one-half turn to the left.
6. Press the “ESC Off” button located in the lower switch
bank below the climate control four times within twenty
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an
additional one-half turn to the right.
8. Turn the ignition switch to the OFF position and then
back to the ON position. If the sequence was completed
properly, the “ESC Off Indicator Light” will blink several
times to confirm HSA is disabled.
9. Repeat these steps if you want to return this feature to
its previous setting.Hill Descent Control (HDC) – If Equipped
HDC is only intended for low speed off-road driving.
HDC maintains vehicle speed while descending hills in
off-road driving conditions by applying the brakes when
necessary.
When enabled, HDC senses the terrain and activates
when the vehicle is descending a hill. HDC speed may be
adjusted by the driver to suit the driving conditions. The
speed corresponds to the transmission gear selected.
GearApproximate HDC Set Speed
1st 1 mph (1.5 km/h)
2nd 3 mph (4.5 km/h)
DRIVE 7.5 mph (12 km/h)
REVERSE 1 mph (1.5 km/h)
NEUTRAL 3 mph (4.5 km/h)
However, the driver can override HDC operation by
applying the brake to slow the vehicle down below the
HDC control speed. If more speed is desired during HDC
350 STARTING AND OPERATING
control, the accelerator pedal will increase vehicle speed
in the usual manner. When either the brake or the
accelerator is released, HDC will control the vehicle at the
original set speed.
NOTE:HDC is available on vehicles equipped with the
MP1522 transfer case.
•The transfer case must be in 4WD LOW range to
enable HDC.
•HDC is enabled only when the “Hill Descent Control
Indicator Light” in the instrument cluster is on solid.
•HDC will NOT activate when the automatic transmis-
sion is in PARK.
•HDC will NOT activate on level ground.
•HDC will NOT activate at vehicle speeds above
30 mph (50 km/h). The “Hill Descent” button is located in the lower switch
bank below the climate control.
Enabling HDC
1. Shift the transfer case into 4WD LOW range. Refer to
“Four-Wheel Drive Operation” in “Starting and Operat-
ing” for further information.

NOTE:If the transfer case is not in 4WD LOW range,
the “Hill Descent Control Indicator Light” will flash for
five seconds and HDC will not be enabled.
Disabling HDC
1. Press the “Hill Descent” button or shift the transfer
case out of 4WD LOW range. The “Hill Descent Control
Indicator” light in the instrument cluster will turn off.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
ESC 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, ESC applies the brake of the appro-
priate 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.
The “ESC Activation/Malfunction Indicator Light” lo-
cated in the instrument cluster will start to flash as soon
as the tires lose traction and the ESC system becomes
active. The “ESC Activation/Malfunction Indicator
352 STARTING AND OPERATING
Light” also flashes when the TCS is active. If the “ESC
Activation/Malfunction 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!
The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent col-
lisions, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. The capabilities of an ESC equipped
vehicle must never be exploited in a reckless or
dangerous manner which could jeopardize the user ’s
safety or the safety of others.
ESC Operating Modes
Depending upon model and mode of operation, the ESC
system has up to three operating modes: “ESC On”
“Partial Off,” and “Full Off.”
ESC On – Two-Wheel Drive Vehicles And Four-Wheel
Drive Vehicles In 2WD And 4WD High Range
This is the normal operating mode for ESC when oper-
ating a two-wheel drive vehicle. It is also the normal
mode for operating a four-wheel drive vehicle in 2WD or
4WD HIGH range. The ESC system will be in “ESC On”
mode whenever the vehicle is started or the transfer case
(if equipped) is shifted out of 4WD LOW range. This
mode should be used for most driving situations. ESC
should only be turned to “Partial Off” or “Full Off” for
specific reasons as noted. Refer to “Partial Off” and to
“Full Off” for additional information.

STARTING AND OPERATING 353
Partial Off – Two-Wheel Drive Vehicles And
Four-Wheel Drive Vehicles In 2WD And 4WD High
Range
The “Partial Off” mode is intended for driving in deep
snow, sand, or gravel. This mode raises the threshold for
TCS and ESC activation, which allows for more wheel
spin than what ESC normally allows.
The “ESC Off” button is located in the lower switch bank
below the climate control. To enter the “Partial Off”
mode, momentarily press the “ESC Off” button and the
ESC Activation/Malfunction Indicator Light” will illu-
minate. To turn the ESC on again, momentarily press the
ESC Offbutton and the ESC Activation/Malfunction
Indicator Light” will turn off. This will restore the normal
“ESC On” mode of operation. NOTE:
To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the
“Partial Off” mode by momentarily pressing the “ESC
Off” button. Once the situation requiring “Partial Off”
mode is overcome, turn ESC back on by momentarily
pressing the “ESC Off” button. This may be done while
the vehicle is in motion.
Full Off – Four-Wheel Drive Vehicles In 4WD High
And 4WD Low Range
The “Full Off” mode is intended for off-highway and
off-road use when ESC stability features could inhibit
vehicle maneuverability due to trail conditions.
The “ESC Off” button is located in the lower switch bank
below the climate control panel. To enter “Full Off”
mode, press and hold the “ESC Off” button for five
seconds while the vehicle is stopped with the engine
running. After five seconds, the “ESC Activation/

Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle at or above
maximum load is dangerous. The added strain on
your tires could cause them to fail. You could have a
serious collision. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision. Al-
ways use radial tires in sets of four. Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized dealer for radial tire repairs.
