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.
Oil Pressure Gauge
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.
