9. Electronic Stability Control (ESC) Indicator
Light/Traction Control System (TCS) Indicator Light –
If EquippedIf the Electronic Stability Control (ESC)/
Traction Control System (TCS) Indicator Light
begins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. This indicator light starts to flash as soon as the
tires lose traction and the Electronic Stability Control
(ESC) becomes active. The “ESC/TCS Indicator Light”
also flashes when TCS is active. Be sure to adapt your
speed and driving to the prevailing road conditions. If
the “ESC/TCS Indicator Light” is on solid, the ESC
system has been turned off by the driver or a temporary
condition exists that will not allow full ESC function.
10. Exhaust Brake Indicator Light
This light will illuminate when the exhaust brake has
been turned on. 11. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
12. Oil Pressure Gauge
The pointer should always indicate some oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate a
lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
13. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.

20. Anti-Lock Brake (ABS) Warning LightThis light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the “ABS Warning Light” remains on or turns on while
driving, it indicates that the anti-lock portion of the brake
system is not functioning and that service is required.
However, the conventional brake system will continue to
operate normally if the “Brake Warning Light” is not on.
If the “ABS Warning Light” is on, the brake system
should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “ABS Warning Light”
does not turn on when the ignition switch is turned to the
ON position, have the light inspected by an authorized
dealer. 21. Tire Pressure Monitoring Telltale Light – If
Equipped
Each tire, including the spare (if provided),
should be checked monthly, when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)

As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.

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.

set period of time when the engine is at operating
temperature. Idle time can be set in 5 minute increments
between 5 and 30 minutes. See your local authorized
dealer to enable this feature.
Programmable Maximum Vehicle Speed (Chassis
Cab Only)
This feature allows the owner to set a maximum vehicle
speed for the vehicle. The 3500 Series maximum vehicle
speed can be set between 40 mph (64 km/h) and 87 mph
(164 km/h). The 4500/5500 Series maximum vehicle
speed can be set between 40 mph (64 km/h) and 85 mph
(136 km/h). See your local authorized dealer to enable
this feature.
NOTE:
DO NOT set the maximum vehicle speed to a
value greater then what the vehicle tires are rated for.
