INSTRUMENTS AND CONTROLS 79
If the pressure in a brake circuit air tank drops below approximately 420 kPa (65 psi), the
red LED light in the lower left corner of the gauge will come on and the STOP tell-tale
warning indicator comes on. In addition, the buzzer comes on if the vehicle starts to move
at speed higher than 1.6 km/h (1 mph). If the vehicle is stationary, only the STOP tell-tale
warning and red LED light appear.

Stop Tell-Tale
If the air pressure drops down below 420 kPa (65 psi) in both systems, the spring brakes will
automatically engage to stop the vehicle.

DANGER
Failure to take necessary action when the
STOP tell-tale is on can ultimately result
in automatic engine shutdown and loss
of power steering assist. Vehicle crash
can occur, resulting in personal injury or
death.
The oil pressure limit is dependent on the engine manufacturer’s electronic program. When
the oil pressure is too low, the red STOP tell-tale illuminates, the buzzer sounds, and the
oil pressure symbol appears on the Driver Information Display (DID) screen. For example,
if the engine is at risk, the EECU may derate the engine power. Bring the vehicle to a
safe stop where the problem can be checked.
