NOTE:
•
Engine idle speed will automatically increase to
1,000 RPM and engage the Variable Geometry Tur-
bocharger at low coolant temperatures to improve
engine warm-up.
•
Automatic equipped vehicles with optional Keyless
Enter ‘n Go™ – If the ENGINE START/STOP button is
pushed once while in PARK with the ignition off and
driver’s foot on the brake pedal, the vehicle will
automatically crank and start after the “Wait to
Start” time has elapsed. If it is desired to abort the
start process before it completes, the driver’s foot
should be fully removed from the brake pedal prior
to pushing the start button again in order for the
ignition to move directly to off.
•
If the engine stalls, or if the ignition switch is left on
for more than two minutes after the Wait To Start
Indicator Light goes out, reset the intake air heater
by turning the ignition switch to the OFF position for
at least five seconds and then back to the ON/RUN
position. Repeat steps 1 through 5 of “Starting Pro-
cedure – Engine Manifold Air Temperature 0°F To
66°F (–18°C to 19°C).”
STARTING PROCEDURE — ENGINE
MANIFOLD AIR TEMPERATURE
BELOW 0°F (-18°C)
In extremely cold weather below 0°F (-18°C) it may be
beneficial to cycle the intake air heater twice before
attempting to start the engine. This can be accom-
plished by turning the ignition to OFF position for at
least five seconds and then back to the ON/RUN posi-
tion after the Wait To Start Indicator Light has turned
off, but before the engine is started. However, excessive
cycling of the intake air heater will result in damage to
the heater elements or reduced battery voltage.
NOTE:
If multiple pre-heat cycles are used before starting,
additional engine run time may be required to maintain
battery state of charge at a satisfactory level.
1. If the engine stalls after the initial start, the ignition
must be turned to the OFF position for at least five
seconds and then to the ON/RUN position to recycle
the intake air heater.
NOTE:
Excessive white smoke and poor engine perfor-
mance will result if intake air heater is not recycled.
2. Heat generated by the intake air heater dissipates
rapidly in a cold engine. If more than two minutes
pass between the time the Wait To Start Indicator
Light turns off and the engine is started, recycle the
intake air heater by turning the ignition switch to the
OFF position for at least five seconds and then back
to the ON/RUN position.
3. If the vehicle is driven and vehicle speed exceeds
19 mph (31 km/h) before the intake air heater post-
heat (after start) cycle is complete, the intake air
heater will shut off.
4. If the engine is cranked for more than 10 seconds,
the post-heat cycle will turn off.
NOTE:
•
Engine idle speed will automatically increase to
1,000 RPM and engage the Variable Geometry Tur-
bocharger at low coolant temperatures to improve
engine warm-up.
•
When a diesel engine is allowed to run out of fuel or
the fuel gels at low temperatures, air is pulled into
the fuel system. If your engine has run out of fuel
page 294.
•
If the engine stalls, or if the ignition switch is left on
for more than two minutes after the Wait To Start
Indicator Light goes out, reset the intake air heater
by turning the ignition switch to the OFF position for
at least five seconds and then back to the ON/RUN
position. Repeat steps 1 through 5 of “Starting Pro-
cedure – Engine Manifold Air Temperature 0°F to
60°F (-18°C to 19°C).”
STARTING FLUIDS
WARNING!
Starting fluids or flammable liquids must never be
used in the Cummins® diesel engine (see Warning
label). Never pour diesel fuel, flammable liquid, start-
ing fluids (ether) into the air cleaner canister, air
intake piping, or turbocharger inlet in an attempt to
start the vehicle. This could result in a flash fire and
explosion causing serious personal injury and engine
damage.
The engine is equipped with an automatic electric air
preheating system. If the instructions in this manual are
followed, the engine should start in all conditions.
WARNING!
•
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup may
cause serious injury or death.
•
When leaving the vehicle, always remove the key
fob and lock your vehicle.
