CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
NOTE: The TPMS telltale is also accompanied by a
“Low Tire” message in the Electronic Vehicle Information
Center (EVIC) screen. Refer to “Starting and Operating/
Tire Pressure Monitor System (TPMS)” in the Owner’s
Manual for further information. 22. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic (OBDII) system which
monitors the emissions and engine control sys-
tem. If the vehicle is ready for emissions testing, the light
will come on when the ignition is first turned on and
remain on, as a bulb check, until the engine is started. If
the vehicle is not ready for emissions testing the light will
come on when the ignition is first turned on and remain
on for 15 seconds, then blink for 5 seconds, and remain
on until the vehicle is started. If the bulb does not come
on during starting, have the condition investigated
promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.

Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability.
23. Airbag Warning Light This light turns on and remains on for six to
eight seconds as a bulb check when the ignition
switch is first turned ON. If the light is not on
during starting, stays on, or turns on while
driving, have the system inspected by an authorized
dealer as soon as possible. 24. Front Fog Light Indicator Light – If Equipped
This indicator will illuminate when the front fog
lights are on.
25. Seat Belt Reminder Light When the ignition switch is first turned ON, this
light will turn on for five to eight seconds as a bulb
check. During the bulb check, if the driver’s seat
belt is unbuckled, a chime will sound. After the bulb
check or when driving, if the driver’s seat belt remains
unbuckled, the seat belt reminder light will flash or
remain on continuously. Refer to Occupant Restraints/
Enhanced Seat Belt Use Reminder System (BeltAlert )in
“Things To Know Before Starting Your Vehicle” in the

Diesel Exhaust Fluid (DEF) Fault Warning
Messages – Chassis Cab Only
There are three 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 will not start if the DEF system is not serviced
within less than 250 miles (402 km) of the fault being
detected.
When the DEF system needs to be serviced the following
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
driving. The message will be accompanied by a single
chime. We recommend you drive to your nearest
authorized dealer and have your vehicle serviced as
soon as possible.
•Service DEF System Engine Will Not Start In
200 Miles – See Dealer — This message will display if
the DEF system has not been serviced after the “Ser-
vice DEF System – See Dealer” message is displayed.
This message will continuously display until the mile-
age counter reaches zero, and will be accompanied by
a periodic chime. The message will continue to count-
down until it reaches zero unless the vehicle is ser-
viced. We recommend you drive to your nearest
authorized dealer and have your vehicle serviced
immediately.
NOTE: Under some circumstances this mileage counter
may start with a value of less than 200 miles (322 km). For
example, if recurring faults are detected in a time interval
of less than 40 hours, the counter may restart at the value
where it stopped when a previous fault was temporarily
remedied, or at a minimum of 50 miles (80 km).
