INSTRUMENTS AND CONTROLS
77
Middle and Lower Tell-Tales
The middle and lower tell-tales provide vehicle and component status
information. For more information, refer to the Driver Information
Display manual.
Driver Information Display (DID)
The DID gives the operator necessary and important information about
the vehicle and components. For more information about the DID, refer
to the Driver Information Display manual.
Fuel Level Gauge
The fuel level gauge is connected to a fuel sensor unit in the fuel tank.
There is only one sensor even if the vehicle is equipped with dual
tanks.
Voltmeter Gauge (Basic Level Cluster Only)
The voltmeter gauge shows the battery voltage. The voltmeter gauge is
included only in the basic level instrument cluster. Battery voltage is
displayed in the DID for the mid and high level instrument clusters.
Intake Manifold Pressure Gauge (High Level Cluster Only)
The intake manifold pressure gauge indicates intake manifold pressure
to the engine. The pressure generated by the intake manifold pressure
should be the same at a given engine temperature, speed and load.
Intake manifold pressure will vary for different engines and vehicle
models. By monitoring the gauge, the operator can avoid engine
problems.
Application Air Pressure Gauge (High Level Cluster Only)
Air gauges are connected to the air brake system via sensors. They will
indicate the brake application pressure from either the front, rear or
trailer circuit pressure. The gauge will not register air pressure until the
foot brake pedal is depressed or the trailer hand brake is applied.
