Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight
parking for fuel, engine coolant, oil, or other
fluid leaks. Also, if gasoline fumes are de-
tected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are sus-
pected. The cause should be located and
corrected immediately.

ther information.
Automatic Transmission
Start the engine with the transmission gear
selector in the PARK position. Apply the
brake before shifting to any driving range.
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 (-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 tem-
peratures under -20°F (-28°C).
151

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 dealer.
• A 12 Volt heater built into the fuel filterhousing 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 Starting Procedure — Keyless
