trailer or a PLC diagnostic tool is
connected. If the light remains on
after the vehicle is started,
continues to flash or fails to illuminate, have the system serviced
immediately.
Parking brake warning (Hydraulic brakes only)
Momentarily illuminates when the

and the engine is off. Also
illuminates when the parking brake
is engaged. If the brake warning
lamp does not illuminate at these
times, seek service immediately.

Check trans (Allison automatic transmission)
The lamp will illuminate for several
seconds after the ignition is turned
to the ON position. Illumination of
this light indicates that a problem
has been detected and shifting may be restricted. Depending upon the
severity of the problem, the read-out digit on the shifter display may be
blank. Operation may continue in order to reach service assistance. The
ECU may not respond to shift selector requests, since operating
limitations are being placed on the transmission, i.e. upshifts and
downshifts may be restricted. Direction changes will not occur.
Refer to the Transmission Operator’s Manual for more information.

Water in fuel (if equipped)
During refueling it is possible for
water-contaminated diesel fuel to be
pumped into your fuel tank. Your
vehicle fuel system is equipped with
a fuel filter/water separator to
remove water from the fuel. The indicator light illuminates when the fuel
filter/water separator has a significant quantity of water, or when the
ignition key is switched to the START position. If the light illuminates
when the engine is running, stop the vehicle as soon as safely possible,
shut off the engine and drain the filter bowl. Allowing water to stay in
the system could result in extensive damage to, or failure of, the fuel
injection system.
To drain the fuel filter/water separator (refer toMaintenance and
Specificationschapter for procedure). Rotate the valve at the bottom of
the filter assembly allowing water to drain from the system. Close the
valve upon completion.
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
Air clean warning (if equipped)
Illuminates when the air system is
restricted (dirty, clogged).
Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or flash faster, check for a burned-out
turn signal bulb. Refer toExterior bulbsin theLightschapter.

Air pressure gauge and warning buzzer (if equipped)
Indicates the amount of air pressure
in the brake system (green=primary,
red=secondary) in pounds per
square inch. When the pressure is
too low for normal brake operation
(less than 414 kPa [60 psi]) and the
ignition is turned to ON:
•a warning buzzer sounds
•the warning light illuminates
All vehicles have a dual-pointer air
pressure gauge to indicate the pressure in both brake circuits.
Vehicles equipped with rear air suspension also have a dual-pointer air
pressure gauge.
Do not drive the vehicle when the low air pressure buzzer is
sounding or the warning light is lit. These warnings indicate
there is not enough air pressure for the brake or suspension system to
operate properly.
Battery voltage gauge
Indicates battery voltage. If the
pointer moves and stays outside the
normal operating range, have the
vehicle’s electrical system checked
as soon as possible.

(All statistics based on U.S. data)
Reasons given... Consider...
“Crashes are rare events”36 700 crashes occur every day.
The more we drive, the more we are
exposed to“rare”events, even for
good drivers.1 in 4 of us will be
seriously injured in a crash during
our lifetime.
“I’m not going far”3of4fatal crashes occur within25
miles of home.
“Belts are uncomfortable”We design our safety belts to enhance
comfort. If you are uncomfortable -
try different positions for the safety
belt upper anchorage and seatback
which should be as upright as
possible; this can improve comfort.
