INSTRUMENT CLUSTER DESCRIPTION
1. Speedometer
Indicates vehicle speed.
2. Brake Warning Light
The BRAKE warning light will come on when
the ignition is first turned on, and stay on
briefly as a bulb check. If the bulb does not
come on during starting, have the bulb re-
paired promptly. If the light stays on longer, it may be an
indication that the parking brake has not been released.
If the light remains on when the parking brake is off, it
indicates a possible brake hydraulic system malfunction
or low fluid level. In this case, the light will remain on
until the cause is corrected. If a brake malfunction is
indicated, immediate repair is necessary and continued
operation of the vehicle in this condition is dangerous.3. Turn Signal Indicator Light
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about one mile with the turn signals on, a chime
will sound to alert you to turn the signals off. If either
indicator flashes at a rapid rate, check for a defective
outside light bulb.
4. High Beam Indicator Light
Indicates that headlights are on high beam.
5. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD II that monitors engine and auto-
matic transmission control systems. The light will
illuminate when the key is in the ON position

16. Electronic Stability Program (ESP) Warning
Light/Brake Assist System (BAS) Warning Light
The ESP/BAS warning light in the instrument
cluster comes on when the ignition switch is
turned to the ªONº position. The light should
go out with the engine running. If the ESP/
BAS warning light comes on continuously with the
engine running, a malfunction has been detected in either
the ESP or the BAS system. If this light stays illuminated,
have the ESP and BAS checked at your authorized dealer
as soon as possible.
17. 4WD LOW Mode Indicator Light Ð If Equipped
This light alerts the driver that the vehicle is in
the 4WD LOW mode. The front and rear drive-
shafts are mechanically locked together forcing
the front and rear wheels to rotate at the same
speed.18. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for 5 to 8 seconds as a bulb check.
During the bulb check, if the driver's seat belt is
unbuckled, a chime will sound. After the bulb check or
when driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Warning Light will flash
or remain on continuously. Refer to9Enhanced Driver
Seat Belt Reminder System (BeltAlert)9in the Occupant
Restraints section for more information.
19. Cruise Indicator Light
This indicator lights when the speed control
system is turned ON.
20. Odometer
The odometer shows the total distance the vehicle has
been driven.

engine is started. If the light stays on or turns on while
driving, it indicates a problem with the charging system.
Immediate service should be obtained.
26. Low Fuel Warning Light
This light will turn on and a single chime will
sound when the fuel level drops to 1/8 tank. The
Low Fuel Warning Light may turn on and off again,
especially during and after hard braking, accelerations,
or turns. This occurs due to the shifting of the fuel in the
tank.
27. Glow Plug Indicator Light Ð Diesel Only
This light will illuminate when the ignition
switch is first turned to the ON position. Wait
until the light turns off before starting the
vehicle. Refer to ªStarting Proceduresº in Sec-
tion 5 of this manual.ELECTRONIC VEHICLE INFORMATION CENTER
(EVIC)
The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display. It is located on the
bottom of the tachometer in the instrument cluster. The
EVIC consists of the following:
²System Status
196 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:
²Use of Climatized ULSD Diesel Fuel or Number 1
ULSD Diesel Fuel results in a noticeable decrease in
fuel economy.
²Climatized ULSD Diesel Fuel is a blend of Number 2
ULSD and Number 1 ULSD Diesel Fuels which re-
duces the temperature at which wax crystals form in
fuel.
NOTE:This engine requires the use ofªUltra Low
Sulfur Diesel Fuel.ºUse of incorrect fuel could result in
exhaust system damage. Refer to ªFuel Requirementsº in
this section for further details on fuel recommendations.
Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0ÉF (-18ÉC). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase startingcapability at low temperatures. Suitable battery blankets
are available from your authorized Mopartdealer.
Engine Starting Procedure
WARNING!
NEVER pour fuel or other flammable liquid into the
air inlet opening in an attempt to start the vehicle.
This could result in a flash fire causing serious
personal injury.
1. The gear selector must be in the ªNº (Neutral) or ªPº
(Park) position before you can start the engine.
2. Turn the ignition key to the ON position.
3. Watch for the ªGlow Plug Indicator Lightº in the
instrument cluster. Refer to ªInstrument Clusterº in
Section 4. It will glow for two to ten seconds or more,

Shifting Procedures
4HIto4LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h),
key ON or engine running, shift the transmission into N
(Neutral), and raise the transfer case T-handle. ªThe 4WD
LOW Indicator Lampº in the instrument cluster will
begin to flash and remain on solid when the shift is
complete. Release the T-handle.
NOTE:If shift conditions/interlocks are not met, or a
transfer case motor temperature protection condition
exists, a ªCHECK SHIFT PROCEDURESº message will
flash from the EVIC (Electronic Vehicle Information Cen-
ter). Refer to ªElectronic Vehicle Information Center
(EVIC)º in Section 4 of this manual.
