Extreme Cold Weather
Your vehicle may be equipped with three
heating elements; one engine block heater (a
resistance heater installed in the water jacket
of the engine) and two transmission heaters
(one resistance heater installed under the oil
reservoir of the hydraulic actuation system
and one on the differential cover of the trans-
mission). To ensure reliable starting/
operating in extreme cold temperatures, use
of an externally powered electric engine
block/transmission heater (available from
your authorized dealer) is recommended.
They require a 110–115 Volt AC electrical
outlet with a grounded, three-wire extension
cord. Their use is recommended for environ-
ments that routinely fall below -10°F
(-23°C). They should be used when the ve-
hicle has not been running overnight or lon-
ger periods and should be plugged in two
hours prior to start. Their use is required for
cold starts with temperatures under -17°F
(-27°C).NOTE:
The engine is designed to work at an ambient
temperature ranging from -22°F to + 122°F
(-30°C to + 50C°). Rubber, pipes, timing belt
cover and electronic devices are not designed
to work out of this range.
In the case of LOW temperature after Start-
ing, the Automated Manual Transmission
may not be able to engage first gear. In this
case a message "Shift not allowed" appears.
In this situation use the engine block heater.
NOTE:
The engine and transmission block heater
cord is a factory installed 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 starting and reduces the amount of
white smoke generated by a warming
engine.
NORMAL OPERATION
Observe the following when the diesel engine
is operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Generic Warning Light is off.
• Engine Oil Pressure telltale is notilluminated.
Stopping The Diesel Engine
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricat-
ing oil and coolant to carry excess heat away
from the combustion chamber, bearings, in-
ternal components, and turbocharger. This is
especially important for turbocharged diesel
engines.

Refer to the following chart for proper engine
shutdown.STARTING AND OPERATING
