NOTE:
A delay of the start-up can be as long as five seconds under very cold conditions. The
"Wait to Start" telltale will be illuminated during the pre-heat process and the start
will commence upon the telltale going out.
If the "Water in Fuel Indicator Light" remains on, DO NOT START the engine
before you drain the water from the fuel filters to avoid engine damage. Refer to
"Maintenance Procedures/Draining Fuel/Water Separator Filter" in "Maintaining
Your Vehicle" for further information.
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
extension cord.
• Its use is recommended for environments that routinely fall below -10°F. 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.
• 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.
NOTE:
The engine block heater cord is a factory installed option. If your vehicle is not
equipped, heater cords are available from your authorized MOPAR
Water In Fuel Message
If a Water In Fuel message or
sounds five times, the fuel/water separator will need to be drained immediately to
