Check trans (Allison automatic
transmission only):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 theTransmission Operator’s Manualfor more information.
Safety belt:Reminds you to fasten
your safety belt.
Range inhibit:Illuminates when
the transmission is not engaged in
the selected gear. The warning light
will go off when the gearshift lever
is adjusted in to the appropriate gear.
Refer to theTransmission Operator’s Manualfor more information.
Charging system:Illuminates when
the battery is not charging properly.
Turn signal:Illuminates when the
left or right turn signal or the
hazard lights are turned on. If the
indicators stay on or flash faster, check for a burned out bulb.

Safety belt extension assembly
If the safety belt is too short when fully extended, there is an eight inch
(20 cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained from your dealer at no cost.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
Do not use extensions to change the fit of the shoulder belt
across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front seat belt buckle

Note:When starting the engine, do not press the accelerator as engine
damage may result.
1. Ensure headlamps and all accessories are turned off, the parking
brake is applied and the transmission is in the neutral position (or P
[Park] for Allison 2200 transmissions).
2. Turn the key to ON, but do not start the engine. In cooler weather,
the air intake heater may activate the WAIT TO START light in the
instrument cluster.
If the WAIT TO START light
illuminates,do notcrank the engine
until the light goes off.
If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could cause an explosion
and result in property damage and/or personal injury.
3. When the WAIT TO START light turns off, turn the key to START;
when the engine starts, release the key.
If the engine does not start after 30 seconds of cranking, allow two
minutes for the starter to cool before trying again. Excessive cranking
may damage the starter.
After the engine starts:
•On some engines, the WAIT TO
START light should illuminate
after the engine starts. Allow the
engine to idle about three
minutes or until the engine
coolant temperature gauge begins to rise. Maintain idle speed until the
WAIT TO START light cycles off to indicate the air intake heater has
shut off (approximately six minutes). Operating the engine at higher
speeds will reduce the effectiveness of the air inlet heater.
