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 ambi-
ent 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) Dur-
ing 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 perfor-
mance after cold starting at low ambient tempera-
tures. The length of time engine speed is limited is
dependent upon engine coolant temperature.
Engine speed may be briefly limited to 1,000 RPM
after starting with coolant temperature below freez-
ing conditions, and may be limited to 1,000 RPM for
up to approximately two minutes under more severe
cold conditions.
• Coolant Low
— This telltale will turn on to indicate
the vehicle coolant level is low page 287.
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 com-
ponent 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.
When the DEF system needs to be serviced the follow-
ing warnings will display:
• DEF Low Refill Soon
— This message will display
when the low level is reached, during vehicle start
up, and with increased frequency during vehicle
operation. It will be accompanied by a single chime.
Approximately 5 gallons (19 Liters) of DEF is
required to refill the tank when this message is ini-
tially displayed on pickup applications, and approxi-
mately 7 gallons (26 Liters) are required on chassis-
cab applications.
•
Speed Limited to 5 MPH in XXX mi Refill DEF
— This
message will continuously display if the “DEF Low
Refill Soon” message is ignored, and the frequency
of occurrence of the chime will increase unless up
to 2 gallons (7.5 Liters) of DEF is added to the tank.
•
5 MPH Max Speed on Restart, Long Idle or Refuel
Refill DEF
— This message will continuously display
when the counter reaches zero, and will be accom-
panied by a periodic chime.
The vehicle will only be capable of a maximum
speed of 5 mph upon the first of the following condi-
tions to occur:
○
If the vehicle is shut off and restarted.
○
If the vehicle is idled for an extended period of
time, approximately one hour or greater.
○
If the system detects that the level of fuel in the
tank has increased.
Add a minimum of 2 gallons (7.5 Liters) of DEF to
the tank in order to avoid vehicle operation at a
maximum speed of 5 mph (8 km/h).
NOTE:
A minimum of 2 gallons (7.5 Liters) may be required to
restore normal vehicle operation. Although the vehicle will
start normally and can be placed in gear after this mes-
sage has been initially displayed, extreme caution should
be utilized since the vehicle will only be capable of maneu-
vering at a maximum speed of 5 mph (8 km/h).
Diesel Exhaust Fluid (DEF) Fault
Warning Messages
There are five different messages which are displayed if
the vehicle detects that the DEF system has been filled
with a fluid other than DEF, has experienced compo-
nent 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.
When the DEF system needs to be serviced the follow-
ing warnings will display:
•
Service DEF System See Dealer
— This message will
display when the fault is initially detected, each time
the vehicle is started, and periodically during driv-
ing. The message will be accompanied by a single
chime. We recommend you drive to the nearest
authorized dealer and have your vehicle serviced as
soon as possible.
