NOTE:In order to ensure proper operation, the Elec-
tronic Speed Control System has been designed to shut
down if multiple Speed Control functions are operated at
the same time. If this occurs, the Electronic Speed ControlSystem can be reactivated by pushing the Electronic
Speed Control ON/OFF button and resetting the desired
vehicle set speed.
To Activate
Push the ON/OFF button. The Cruise Indicator Light in
the instrument cluster will illuminate. To turn the system
off, push the ON/OFF button a second time. The Cruise
Indicator Light will turn off. The system should be
turned off when not in use.
WARNING!
Leaving the Electronic Speed Control system 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
leave the system OFF when you are not using it.1 — ON/OFF 2 — RES +

decrease until the button is released. Release the button
when the desired speed is reached, and the new set speed
will be established.
Pressing the SET (-) button once will result ina1mph
(1.6 km/h) decrease in set speed. Each subsequent tap of
the button results in a decrease of 1 mph (1.6 km/h).
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Electronic Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE:The Electronic Speed Control system maintains
speed up and down hills. A slight speed change on
moderate hills is normal.On steep hills, a greater speed loss or gain may occur so
it may be preferable to drive without Electronic Speed
Control.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have an accident. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.

NOTE:The courtesy/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. If the interior
lights are left on after the ignition is turned OFF, they will
extinguish after 15 minutes.
ELECTRICAL POWER OUTLETS
The auxiliary 12 Volt (13 Amp) power outlets can provide
power for in-cab accessories designed for use with the
standard “cigar lighter” plug. The 12 Volt power outlets
have a cap attached to the outlet indicating “12V DC”,
together with either a key symbol or a battery symbol.
A key symbol indicates that the key must be in the ON or
ACC positions for the outlet to provide power. The
battery symbol indicates that the outlet is connected to
the battery, and can provide power at all times.
NOTE:To ensure proper operation a MOPARknob
and element must be used.

The key symbol indicates that this outlet can supply
power when the key is in the ON or ACC positions.
All accessories connected to the outlet(s) should be
removed or turned off when the vehicle is not in use to
protect the battery against discharge.
WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of
outlet should be inserted into any 12 Volt outlet.
•Do not touch with wet hands.
•Close the lid when not in use and while driving
the vehicle.
•If this outlet is mishandled, it may cause an
electric shock and failure.

CAUTION!
•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 the engine from starting.
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge 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.
CIGAR LIGHTER AND ASH RECEIVER — IF
EQUIPPED
A removable ash receiver and cigar lighter are available.
For vehicles with a bench seat the cupholder tray can be
used to hold the ash receiver.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
The Tachometer indicates engine speed in revolutions per
minute (RPM x 1000).
CAUTION!
Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
damage may occur.
2. Turn Signal Indicators
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
NOTE:
•A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on.
•Check for an inoperative outside light bulb if either
indicator flashes at a rapid rate.
3. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON/RUN position.
4. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

6. 4 LOW
This light alerts the driver that the vehicle is in
the four-wheel drive LOW mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. Low range provides a greater
gear reduction ratio to provide increased torque at the
wheels.
7. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned to ON/RUN and remain on briefly as a
bulb check. If the light does not come on during starting,
have the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when thevehicle has completely stopped and the shift lever is
placed in the PARK position, the light should turn off.
If the light remains lit with the engine running, your
vehicle will usually be drivable; however, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required and you may experience reduced performance,
an elevated/rough idle or engine stall and your vehicle
may require towing.
For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” for further information.
8. 4WD Indicator
This light indicates the vehicle is in four-wheel
drive and 4LOCK. 4WD allows all four wheels
to receive torque from the engine simultane-
ously.

9. SVC (Service) 4WD
The SVC 4WD light monitors the electric shift
four-wheel drive system. If the SVC 4WD light
stays on or comes on during driving, it means
that the four-wheel drive system is not func-
tioning properly and that service is required.
For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” for further information.
10. TOW/HAUL
The TOW HAUL button is located on the
center stack switch bank. This light will illumi-
nate when TOW HAUL mode is selected11. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
12. Oil Pressure Gauge — If Equipped
The pointer should always indicate some oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate a
lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
13. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.
