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.
