122 GETTING TO KNOW YOUR INSTRUMENT PANEL
Exhaust System — Regeneration Completed —
This message indicates that the DPF
self-cleaning is completed. If this message is
displayed, you will hear one chime to assist in
alerting you of this condition.
Exhaust Service Required — See Dealer Now —
This message indicates regeneration has been
disabled due to a system malfunction. At this
point the engine Powertrain Control Module
(PCM) will register a fault code, the instrument
panel will display a MIL light.
Exhaust Filter Full — Power Reduced See Dealer
— This message indicates the PCM has derated
the engine to limit the likelihood of permanent
damage to the after-treatment system. If this
condition is not corrected and a dealer service is
not performed, extensive exhaust after-treat-
ment damage can occur. To correct this condi-
tion it will be necessary to have your vehicle
serviced by your local authorized dealer.
NOTE:
Failing to follow the oil change indicator, changing
your oil and resetting the oil change indicator by
0 miles remaining will prevent the diesel exhaust
filter from performing it's cleaning routine. This will
shortly result in a Malfunction Indicator Light (MIL)
and reduced engine power. Only an authorized
dealer will be able to correct this condition.
Cold Ambient Derate Mode Messages
The vehicle will display messages when a derate
(engine power reduction) is activated to protect the
engine during start up in cold ambient
temperatures.
Engine Power Reduced During Warm-Up — This
message will display during start up when the
ambient temperature is between 10°F (-12°C)
and -10°F (-23°C).
Engine Power Reduced Up To 30 Sec (Seconds)
During Warm-Up — This message will display
during start up when the ambient temperature
is between -10°F (-23°C) and -25°F (-32°C).
Engine Power Reduced Up To 2 Min (Minutes)
During Warm-Up — This message will display
during start up when the ambient temperature
is -25°F (-32°C) and below.
Your vehicle is equipped with an engine warm
up protection feature that may limit engine
performance after cold starting at low ambient
temperatures. The length of time engine speed
is limited is dependent upon engine coolant
temperature. Engine speed may be briefly
limited to 1000 RPM after starting with coolant
temperature below freezing conditions, and
may be limited to 1000 RPM for up to
approximately 2 minutes under more severe
cold conditions.
Coolant Low — This telltale will turn on to indi-
cate the vehicle coolant level is low. Refer to
“Dealer Service” in “Servicing And Mainte-
nance” for more information.
Diesel Exhaust Fluid (DEF) Warning
Messages
There are four different messages which are
displayed if the vehicle detects that the DEF
system has been filled with a fluid other than DEF,
has experienced component failures, or when
tampering has been detected. The vehicle may be
limited to a maximum speed of 5 MPH (8 km/H) if
the DEF system is not serviced within less than
200 miles (322 km) of the fault being detected.
CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with continued
operation.
