WARNING!
ABS (Anti-Lock Brake System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevail-
ing road conditions. ABS cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, 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 reck-
less or dangerous manner which could jeopardize
the user’s safety or the safety of others.
TCS (Traction Control System)
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“Full Off”modes. Refer to“ESP
(Electronic Stability Program)”in this section.

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 cannot
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.NOTE:Anytime the ESP system is in the“Full Off”
mode, ERM is disabled. Refer to ESP (Electronic Stability
Program) for a complete explanation of the available ESP
modes.
WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
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.
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.

or gravel conditions and more wheel spin than ESP
would normally allow is required to gain traction. To
turn ESP on again, momentarily depress theESP 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.
Full 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. In this mode, all ESP and TCS stability features
are turned off except for the“limited slip”feature de-
scribed in the TCS section. After 5 seconds, a chime will
sound, theESP/TCS Indicator Lightwill illuminate,
and theESP OFFmessage will appear in the Electronic
ESP Control Switch

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). TheESP/
TCS Indicator Lightwill always be illuminated in 4WD
low range when ESP is off.
Full 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. In this mode, all ESP and TCS stability features
are turned off except for the“limited slip”feature de-
scribed in the TCS section. After 5 seconds, a chime will
sound, and the“ESP OFF”message will appear in theElectronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)”in Sec-
tion 4 of this manual. (See page 187 for more informa-
tion.) To turn ESP on again, momentarily depress the
“ESP Control Switch”. This will restore the normal“Par-
tial Off”mode of operation in 4wd low range.
NOTE:The“ESP OFF”message will display and the
audible chime will sound when the gear selector is
placed into the“P”(Park) position from any position
other than“P”(Park), and then moved out of the“P”
(Park) position. This will occur even if the message was
previously cleared.

WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP and ERM are unavailable. In
an emergency evasive maneuver, the ESP and ERM
systems will not engage to assist in maintaining
stability. The“Full Off”mode is intended for off-
highway or off-road use only.
ESP/BAS Warning Lamp and ESP/TCS Indicator
Light
The malfunction indicator lamp 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 go out with the engine
running.If the“ESP/BAS Warning Lamp”comes on
continuously with the engine running, a mal-
function has been detected in either the ESP or
the 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.
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.

To Set at a Desired Speed
When the vehicle has reached the desired speed, press
and release the SET button. Release the accelerator and
the vehicle will operate at the selected speed.
To Deactivate
A soft tap on the brake pedal, normal braking, or pressing
the CANCEL button will deactivate the Speed Control
without erasing the memory. Pressing the ON·OFF to
turn the system OFF or turning off the ignition erases the
memory.
To Resume Speed
To resume a previously set speed, press and release the
RES·ACCEL button. Resume can be used at any speed
above 25 mph (40 km/h) for 5.7L engines, and 30 mph (48
km/h) for 3.7L/4.7L engines.
To Vary the Speed Setting
When the Speed Control is ON, speed can be increased
by pressing and holding the RES·ACCEL button. When
the button is released, a new set speed will be estab-
lished.
Tapping the RES·ACCEL button once will result in a 2
mph (3 km/h) (3.7L/4.7L Models) or a 1 mph (2 km/h)
(5.7L Models) speed increase. Each time the button is
tapped, speed increases, so tapping the button three
times will increase speed by 6 mph (10 km/h) (3.7L/4.7L
Models) or 3 mph (5 km/h) (5.7L Models), etc.
To decrease speed while Speed Control is ON and SET,
press and hold the DECEL button. Release the button
when the desired speed is reached, and the new speed
will be set.

The power outlets are a direct feed from the battery so
they receive power whether the ignition is in the ON or
OFF position.
All accessories connected to this outlet should be re-
moved or turned off when the vehicle is not in use to
protect the battery against discharge.CAUTION!
Electrical Outlet Use With Engine Off
•Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not
in use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
•After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle’s battery.

If the rear wiper is operating when the ignition is turned
OFF, the wiper will automatically return to the“Park”
position.
If the liftgate flipper glass is open, connection to the rear
window wiper is interrupted preventing activation of the
rear wiper blade. When the liftgate flipper glass is closed,
the rear wiper switch or the ignition switch needs to be
turned OFF and ON to restart the rear wiper.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.
ROOF LUGGAGE RACK—IF EQUIPPED
External racks do not increase the total load carrying
capacity of the vehicle. Be sure that the total occupant
and luggage load inside the vehicle, plus the load on the
luggage rack, do not exceed the rated vehicle capacity.
This vehicle is not equipped with roof rack cross rails as
built, unless ordered as optional equipment. Cross rails
must be installed prior to carrying loads on the roof rack.
If not equipped, your authorized dealer can order and
install Moparcross rails built specifically for this roof
rack system or a number of after market rails that are
tailored to your life-style or activities.
