Safety Checks You Should Make Inside The
Vehicle
Heater Defroster Ducts
Inspect the heater defroster ducts for proper operation.
Check for proper air flow through all defroster ducts. If
there are any question regarding the operation of your
heater defroster ducts, have the system checked by an
authorized dealer
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.) or if the front airbags have deployed. If there is any
question regarding belt or retractor condition, replace the
belt. Airbag Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers or comes
on while driving, have the system checked by an autho-
rized dealer. If there is a problem with the airbag light the
seatbelt light will flash.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for tread wear or uneven wear patterns.
Check for stones, nails, glass or other objects lodged in
the tread.
Inspect for tread cuts or sidewall cracks. Check wheel
nuts for tightness and tires for proper pressure.76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Each heated seat switch has two settings (HI and LOW).
Press the switch once to obtain High heat level, then
press the switch again to obtain Low heat level. Pressing
the switch a third time will turn the heated seats OFF. If
you do not purposefully turn the switch OFF, the seat
heating level will automatically change to the next lower
level, or OFF. The High heat level operates for 30 minutes
(approximate), the Low heat level operates for 30 min-
utes (approximate). The seat heat will also turn OFF
when the ignition is turned OFF. Both of the indicators
ON identifies High heat level. The lower indicator On
only, identifies Low heat level. Flashing indicator lights
on the switch indicate that the Heated Seat System needs
servicing. WARNING!Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time.
Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This may
cause the seat heater to overheat. UNDERSTANDING THE FEATURES OF YOUR VEHICLE 119

INSTRUMENT CLUSTER DESCRIPTION
1. Check Gages
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gages indicate a reading either too high or too low.
Examine the gages carefully, and follow the instructions
above for each indicated problem.
NOTE: When the ignition switch is turned to OFF, the
Fuel Gage, Voltmeter, Oil Pressure and Engine Coolant
Temperature gages may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltmeter
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. If the pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound.
NOTE:
• The voltmeter may show a gauge fluctuation if certain
engine temperatures are below 66°F (19°C). This cy-
cling operation is caused by the post-heat cycle of the
intake manifold heater system. The number of cycles
and the length of the cycling operation is controlled by
the engine control module, this time will not exceed
150 seconds. The needle should then stabilize at the
approximate operation point.
• The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.172 UNDERSTANDING YOUR INSTRUMENT PANEL

Heater Only — If Equipped
The mode control (at the right of the
control panel) can be set in any of the
following positions: NOTE: To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots.
Panel
Outside air flows through the outlets located in the
instrument panel.
Recirculation Modes (Panel or Bi-Level)
Select the recirculation modes when
the outside air contains smoke or
odors. This feature allows for recircu-
lation of interior air only. Air flows
through the panel outlets in this mode.
Air flows through the panel only or
through both the panel and floor vents
depending on the selected mode (panel vs bi-level).Manual Heating Controls UNDERSTANDING YOUR INSTRUMENT PANEL 231

Manual Transmission – If Equipped
Apply the parking brake, place the gearshift control lever
in NEUTRAL and depress the clutch pedal to the floor
before starting the vehicle. This vehicle is equipped with
a clutch interlocking ignition system. It will not start
unless the clutch is fully depressed.
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 Mopar  dealer.
• 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 for252 STARTING AND OPERATING
