STARTING AND OPERATING 111
NOTE:
The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords
are available from an authorized Mopar® dealer.
A 12 Volt heater built into the fuel filter housings
aid in preventing fuel gelling. It is controlled by a
built-in thermostat.
An intake air heater system both improves
engine starting and reduces the amount of
white smoke generated by a warming engine.

NOTE:
The temperature displayed in the instrument
cluster does not necessarily reflect the engine
manifold air temperature Ú page 81. When
engine temperatures fall below 66°F (19°C) the
“Wait To Start” telltale will remain on indicating the
intake air heater system is active.
Follow the steps in the “Normal Starting”
procedure except:
1. The “Wait to Start” telltale will remain on for a
period of time that varies depending on the
engine temperature.
2. While the “Wait to Start” telltale is on, the
instrument cluster will additionally display a
gauge or bar whose initial length represents
the full “Wait to Start” time period. Its length
will decrease until it disappears when the
“Wait to Start” time has elapsed.
3. After the “Wait to Start” telltale goes off, place
the ignition switch in the START position. Do
not press the accelerator during starting.
CAUTION!
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 Ú page 347.
CAUTION!
Do not crank engine for more than 25 seconds
at a time or starter motor damage may result.
Turn the ignition switch to the OFF position and
wait at least two minutes for the starter to cool
before repeating start procedure.
