air from entering the fuel system and stalling the engine.
In cold weather below 0°C (32°F) your Diesel engine will slowly increase
to a higher idle speed if left idling in P (Park). As the engine warms-up,
the engine sound level will decrease due to the activation of
PCM-controlled sound reduction features.
Operation in snow
Vehicle operation in heavy snowfall or in dry loose snow that may swirl
around the front of the vehicle may feed excessive amounts of snow into
the air intake system. This could plug the air cleaner with snow and
cause the engine to stall and/or lose power.
Refer toAir filter restriction gaugeandEngine air filterin the
Instrumentationchapter for more information.
Operation in standing water
Ingestion of water into the Diesel engine can result in immediate and

avoid splashing water into the intake. If the engine stalls, and ingestion
of water into the engine is suspected, do not try to restart the engine.
Consult your dealer for service immediately.
