Engine starting (parking brake applied)
Safety/Emergency
equipment:Prior to entering the cab, verify that the
vehicle is equipped with spare electrical fuses
(if used), three red reflective triangles, a
properly charged and rated fire extinguisher
and wheel chocks. Walk around the vehicle
and check that all steps and grab handles,
inside and out as well as behind, are tight and
clean. Use extreme caution and a three-point
stance at all times. Check door latches for
positive closing, latching and locking.
Starting the engine:Verify the parking brake is set. Depress the
clutch (if equipped with a manual
transmission) and verify the transmission is in
neutral. Vehicles equipped with an automatic
transmission should be in N (Neutral).
When the WAIT TO START indicator light in
the instrument cluster turns off, turn the key
to START.
Oil pressure builds:Make sure engine oil pressure is building to
normal operating range.
Air chime sounds (if
equipped with air
compressor):The low air pressure warning chime should
sound immediately after the engine starts but
before the compressor has built up pressure.
The low air pressure warning chime should
stop when the air pressure reaches 70 psi (483
kPa) (or more). Let the air pressure build to
governed cut-out pressure, which should occur
between 115–130 psi (793–896 kPa).
Accelerator:Depress the accelerator and verify that it
operates smoothly without any binding or
irregular feel. Remove your foot from the
pedal and make sure the engine returns to idle
speed immediately.

Differential lock:Illuminates when
the main differential is locked
(engaged).
Parking brake warning:
Momentarily illuminates when the
ignition is turned to the ON position
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.
Vehicles equipped with the Power Park (air-operated parking
brake) option:If after setting the parking brake on your vehicle the
park brake warning lamp begins to blink, this may indicate a failure in
the parking brake system. Seek service from your dealer immediately.
Trailer ABS brake system:
Illuminates briefly when the engine
is powered-up and only when a PLC
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.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.

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.
High beams:Illuminates when the
high beam headlamps are turned on.
Safety belt warning chime:Sounds when the key is in the ignition and
the driver’s safety belt is not fastened.
Key-in-ignition warning chime:Sounds when the key is left in the
ignition in the OFF/LOCK or ACC position and the driver’s door is
opened.CHECK
