POWER REDUCED TO LOWER ENGINE TEMP — Displayed when
the engine temperature gauge needle moves to H. You may notice
reduced engine power. Refer to Engine coolant in the Maintenance
and Specifications chapter for more information.
CLEANING EXHAUST FILTER (diesel engine only) — Displayed
when the vehicle has entered the cleaning mode. Various engine actions
will raise the exhaust temperature in the Diesel Particulate Filter (DPF)
system to burn off the particles (exhaust soot). After the particles are
burned off, the exhaust temperature will fall back to normal levels. This
message is NORMAL. Refer to your diesel supplement for more
information.
WARNING: When the CLEANING EXHAUST FILTER message
appears in the message center, do not park near flammable
materials, vapors or structures until filter cleaning is complete.
DRIVE TO CLEAN EXHAUST SYSTEM (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.
STOP SAFELY NOW (diesel engine only) — Displayed and a chime
sounds when the vehicle exhaust system temperature exceeds intended
operating range. If this warning occurs, engine power is reduced and the
engine will shut down when the vehicle speed is below 3 mph (5 km/h).
Stop the vehicle as soon as safely possible and contact your
authorized dealer. Depending on the severity of the over-temperature
condition, the vehicle may not restart after cycling the ignition off. If the
vehicle restarts, there may be limited power. If the exhaust
over-temperature condition reoccurs, the message center will display
