Instrument Cluster
ENGINE WARMING PLEASE WAIT XX (diesel engine only) —
Displayed in extremely cold weather, typically below –15°F (–26°C), if
the engine block heater is not utilized. The engine will not respond to
accelerator pedal movement for 30 seconds; this is done so the engine oil
can be properly circulated to avoid engine damage from lack of
lubrication. A timer will begin a countdown from 30 seconds. Once the
counter has reached 0 seconds, OK TO DRIVE will be displayed and the
engine will respond to accelerator pedal movement. Refer to your diesel
supplement for more information.
OK TO DRIVE (diesel engine only) — Displayed when the time
counter has reached 0 (zero) and the engine is sufficiently warm enough
to drive in extremely cold weather (refer to the engine warming please
wait message description mentioned previously). Refer to your diesel
supplement for more information.
WATER IN FUEL DRAIN FILTER (diesel engine only) — Displayed
when the water separator has reached a predetermined capacity and
needs to be drained. Refer to your diesel supplement for more
information.
ENGINE TURNS OFF IN XX (diesel engine only) — Displayed
when the vehicle is in the final 30 seconds of a countdown to where the
engine will intentionally be turned off by the PCM. The diesel engine
shutdown for extended idling is an optional feature. Refer to your diesel
supplement for more information.
ENGINE TURNED OFF (diesel engine only) — Displayed after the
30 second countdown. Refer to your diesel supplement for more information.
DRIVE TO CLEAN EXHAUST FILTER (diesel engine only) —
Displayed when the Diesel Particulate Filter (DPF) is full of particles
(exhaust soot) and the vehicle is not being operated in a manner to
allow normal cleaning. This message will stay on until the exhaust filter
cleaning has begun, at which time the CLEANING EXHAUST FILTER
message will be displayed. It is recommended the vehicle operator drive
the vehicle above 30 mph (48 km/h) until the CLEANING EXHAUST
FILTER message turns off. This message is NORMAL. Refer to your
diesel supplement for more information.
Note: If this message is ignored, your vehicle will continue to fill the
Diesel Particulate Filter (DPF) with particles (exhaust soot). If cleaning
is not permitted, the light will illuminate and engine power may be
limited. If the vehicle is still not operated in a manner to allow cleaning,
the service engine soon light will illuminate and engine power will
be further limited. Dealer service will then be required to restore your
vehicle to full-power operation.
