Instrument Cluster
Trailer ABS brake system (if equipped)
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.
Parking brake warning (Hydraulic brakes only)
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.
Safety belt
Illuminates to remind you to fasten
your safety belts. For more
information, refer to the Seating
and safety restraints chapter.
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.
