Cold Start Procedure

• Turn the ignition switch to the ON position. If the Wait To Start light

appears in the cluster, wait for the light to turn off before starting.

• In extremely cold weather below 0°F (-18°C) it may be beneficial to cycle the

manifold heaters twice before attempting to start the engine. This can be

accomplished by turning the ignition OFF for at least five seconds and then

back ON after the “Wait To Start Light” has turned off, but before the engine is

started. However, excessive cycling of the manifold heaters will result in

damage to the heater elements or reduced battery voltage.

• Refer to the Owner's Manual Diesel Supplement on the DVD for further details.

Engine Idling

• Avoid prolonged engine idling. Long periods of idling may be harmful to your

engine because combustion chamber temperatures can drop so low that the

fuel may not burn completely.

• Incomplete combustion allows carbon and varnish to form on piston rings,

engine valves, and injector nozzles. Also, the unburned fuel can enter the

crankcase, diluting the oil and causing rapid wear to the engine.

• If the engine is allowed to idle, under some conditions the idle speed may

increase to 900 RPM then return to normal idle speed. This is normal

operation.

WARNING!

Remember to disconnect the cord before driving. Damage to the 110–115 volt

electrical cord could cause electrocution.
