5. After engine start-up, check to see that there is oil

pressure.

NOTE:

• Engine idle speed will automatically increase to

1,000 RPM and engage the Variable Geometry Turbo-

charger at low coolant temperatures to improve engine

warm-up.

• If the engine stalls, or if the ignition switch is left ON

for more than two minutes after the “Wait To Start

Light” goes out, reset the grid heaters by turning the

ignition switch to the OFF position for at least five

seconds and then back ON. Repeat steps 1 through 7 of

“Keyless Enter-N-Go Starting Procedure – Engine

Manifold Air Temperature Below 66° F (19° C).”

Extreme Cold Weather

The Cummins® diesel engine is equipped with several

features designed to assist cold weather starting and

operation:
• The engine block heater is a resistance heater installed

in the water jacket of the engine just above and behind

the oil filter. It requires a 110–115 Volt AC electrical

outlet with a grounded, three-wire extension cord.

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 housings aid in

preventing fuel gelling. It is controlled by a built-in

thermostat.

• A heated intake air system both improves engine

starting and reduces the amount of white smoke

generated by a warming engine.
