CAUTION!
Do not leave your vehicle unattended with the en-
gine running as you would not be able to react to the
temperature indicator if the engine overheats.
NOTE:Engine idle speed will automatically increase to
1000 rpm at elevated coolant temperatures to improve
engine cooling.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound.
14. Security Light
The light will flash rapidly for approximately 16 seconds
when the vehicle theft alarm is arming. The light will
flash at a slower rate after the alarm is set. The security
light will also come on for about two seconds when the
ignition is first turned ON.15. Transmission Range Indicator (Automatic
Transmissions Only)
When the gear selector lever is moved on vehicles with
the 48RE transmission, this indicator shows the auto-
matic transmission gear range selected (PRND21).
When the gear selector lever is moved on vehicles with
the 68RFE transmission, this indicator shows the auto-
matic transmission gear range selected (P R N D). Ve-
hicles equipped with Auto-6/Electronic Range Select
(ERS) will display the selection of the desired top gear, in
the position next to the D (Drive).
16. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
If the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.

23. SERV 4WD Indicator
The 4WD indicator will be illuminated whenever the
4WD mode is engaged for either the manual or electric
shift 4WD systems. The SERV 4WD indicator monitors
the electric shift 4WD system. If the SERV 4WD light
stays on or comes on during driving, it means that the
4WD system is not functioning properly and that service
is required.
24. Water In Fuel Indicator
Indicates there is water detected in the fuel
filter. Refer to the Maintenance section, Drain-
ing Fuel/Water Separator Filter, for water
drain procedure. (See page 427 for more information.)
25. Transmission Oil Temperature Warning Light
(Automatic Transmissions Only)
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It mayalso occur when operating the vehicle in a high torque
converter slip condition, such as 4-wheel-drive operation
(e.g. snow plowing, off- road operation). If this light
comes on, stop the vehicle and run the engine at idle or
faster, with the transmission in NEUTRAL until the light
goes off.
26. Wait To Start Indicator
The Wait To Start Indicator will illuminate when
the ignition is turned to the run position and the
intake manifold temperature is below 66 degrees F.
Follow engine starting procedure for proper engine start-
ing and operating. Wait until the Wait To Start Indicator
turns OFF then start the vehicle.
NOTE:The Wait To Start Indicator may not illuminate if
the engine coolant temperature is warm enough.

Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.NOTE:On models equipped with Diesel engines, the
idle speed will automatically increase to 1000 rpm at
elevated coolant temperatures to improve engine cooling.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

272 STARTING AND OPERATING

Automatic Transmission – If Equipped
Start the engine with the selector lever in NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
The Cummins Diesel engine is equipped with several
features designed to assist cold weather starting and
operation:
•The engine block heater is a resistance heater installed
in the water jacket of the engine just above and behind
the oil filter. It requires a 110–115 volt AC electrical
outlet with a grounded, three-wire extension cord.
NOTE:The engine block heater cord is a factory in-
stalled option. If your vehicle is not equipped, heater
cords are available from your authorized Mopardealer.
•A 12–volt heater built into the fuel filter housing aids
in preventing fuel gelling. It is controlled by a built-in
thermostat.
•A heated intake air system both improves engine
starting and reduces the amount of white smoke
generated by a warming engine.
Normal Starting Procedure — Engine Manifold
AirTemperature Above 66°F (19°C)
Observe the Instrument Panel Cluster lights when start-
ing the engine.
1. Always apply the parking brake.
2. Shift into PARK for an automatic transmission. Fully
depress and hold the clutch and shift into NEUTRAL for
a manual transmission. Models with manual transmis-
sion are equipped with a clutch interlocking cranking
system. The clutch must be fully depressed to start the
vehicle.
3. Turn the ignition key to the ON position and look at
the instrument panel cluster lamps.
