Water In Fuel Message
If a Water In Fuel message or
sounds five times, the fuel/water separator will need to be drained immediately to
prevent engine damage.
Refer to "Draining Fuel Water Separator" in this guide for draining instructions or see
your dealer.
Cold Start Procedure
Turn the ignition switch to the ON position. If the Wait To Start
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 accom-
plished 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.
Remember to disconnect the cord before driving. Damage to the 110–115 volt
electrical cord could cause electrocution.
