oxide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious in-
jury or death when inhaled.
• Keep Remote Keyless Entry (RKE) transmitters
away from children. Operation of the Remote Start
System, windows, door locks or other controls
could cause serious injury or death.
ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, provid-
ing the following recommendations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged
periods.
• Use the appropriate transmission gear to prevent
engine lugging.
• Observe vehicle oil pressure and temperature indica-
tors.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carry-
ing or towing significant weight.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Engine Coolant Temperature •This gauge shows the engine coolant temperature.
The gauge pointer will likely show higher tempera-
tures when driving in hot weather, up mountain
grades, or in heavy stop and go traffic. If the red
Warning Light turns on while driving, safely bring
the vehicle to a stop, and turn off the engine. DO
NOT operate the vehicle until the cause is corrected.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
(Continued)
CAUTION! (Continued)
drops back into the normal range. If the pointer
remains on the “H”, turn the engine off immediately
and call an authorized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.

Red TelltaleLight What It Means
Transmission Temperature Indicator Light
This light indicates that the transmission fluid temperature is running hot. This may occur with
severe usage, such as trailer towing. If this light turns on, safely pull over and stop them ve-
hicle. Then, shift the transmission into NEUTRAL and run the engine at idle or faster until the
light turns off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.

Air Suspension Payload Protection Telltale — If
Equipped This telltale will turn on to indicate that the
maximum payload may have been exceeded or
load leveling cannot be achieved at its current
ride height.
Protection Mode will automatically be selected in
order to “protect” the air suspension system, air
suspension adjustment is limited due to payload.
• Water In Fuel Indicator Light — Diesel Only
The “Water In Fuel Indicator Light” will illu-
minate when there is water detected in the fuel
filters. If this light remains on, DO NOT start
the vehicle before you drain the water from the
fuel filters to prevent engine damage. Refer to “Mainte-
nance Procedures/Draining Fuel/Water Separator Fil-
ters” in “Maintaining Your Vehicle” for further
information.

•Wait To Start Light
The “Wait To Start” telltale will illuminate for
approximately two seconds when the ignition is
turned to the RUN position. It’s duration may be longer
based on colder operating conditions. Vehicle will not
initiate start until telltale is out. Refer to “Starting Proce-
dures” in “Starting And Operating” for further
information.
NOTE: The “Wait To Start” telltale may not illuminate if
the intake manifold temperature is warm enough.
• Low Diesel Exhaust Fluid Light
This telltale will turn on to indicate the Diesel
Exhaust Fluid (DEF) is low. 6. EVIC Red Telltales
•
Door Ajar
This light will turn on to indicate that one or
more doors may be ajar.
• Oil Pressure Warning Light
This telltale indicates low engine oil pressure. If
the light turns on while driving, stop the vehicle
and shut off the engine as soon as possible. A chime will
sound when this light turns on.
Do not operate the vehicle until the cause is cor-
rected. This light does not show how much oil is in
the engine. The engine oil level must be checked
under the hood.

•Oil Temperature Warning Light
This telltale indicates engine oil temperature is
high. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as
possible.
• Charging System Light
This light shows the status of the electrical charg-
ing system. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If
the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”. •
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 ON 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
the vehicle has completely stopped and the transmis-
sion is 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
authorized dealer for service as soon as possible. If
the light is flashing when the engine is running,
immediate service is required. You may experience
reduced performance, an elevated/rough idle or en-
gine stall and your vehicle may require towing.

Extreme Cold Weather
The engine block heater is a resistance heater installed in
the water jacket of the engine. It requires a 110–115 Volt
AC electrical outlet with a grounded, three-wire exten-
sion cord. Its use is recommended for environments that
routinely fall below -10°F (-23°C). It should be used when
the vehicle has not been running overnight or longer periods and should be plugged in two hours prior to
start. Its use is required for cold starts with temperatures
under -20°F (-28°C).
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 Diesel Pre-Heat system both improves engine start-
ing and reduces the amount of white smoke generated
by a warming engine.
Starting Fluids
The engine is equipped with a glow plug preheating
system. If the instructions in this manual are followed,

NORMAL OPERATION
Observe the following when the diesel engine is operat-
ing.
•All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Engine Oil Pressure telltale is not illuminated.
• Voltmeter operation:
The voltmeter may show a gauge fluctuation at various
engine temperatures. This is caused by the glow plug
heating system. The number of cycles and the length of
the cycling operation is controlled by the engine control
module. Glow plug heater operation can run for several
minutes, once the heater operation is complete the volt-
meter needle will stabilize.
Cold Weather Precautions
Operation in ambient temperature below 32°F (0°C) may
require special considerations. The following charts sug-
gest these options:
