Diesel Exhaust Fluid (diesel engine only)
It illuminates when the diesel exhaust fluid level falls below
0.5 gallons (1.9L) in the five gallon (19.0L) tank or one gallon
(3.8L) in the nine gallon (34.0L) tank. Refill the tank or, at a
minimum, add at least one gallon (3.8L) to the five gallon (19.0L) tank
or two gallons (7.6L) to the nine gallon (34.0L) tank.
Diesel Particulate Filter (diesel engine only)
It illuminates when the soot level in the diesel particulate filter
has reached a point where it requires operator assistance. See
Diesel particulate filter in the Maintenance chapter, and your
engine operator's manual, for more details.
Do Not Shift (Allison automatic transmission only)
It illuminates while driving if a problem has been detected in
the transmission; shifting may be restricted. Depending on the
severity of the problem, the shifter's digital read-out may turn
blank.
Operation may continue in order to reach service assistance. The control
unit 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 do not occur.
Direction Indicator
It illuminates when the left or right turn signal or the hazard
warning flasher is switched on. If the indicators stay on or flash
faster, check for a burned out bulb.
Electronic Locking Differential
It illuminates when using the electronic locking differential.
Engine Oil Pressure (gasoline engine only)
It illuminates when engine oil pressure is low.
Fasten Safety belt
It illuminates and a chime sounds to remind you to fasten your
safety belt.
