All Wheel Drive control panel
General
The All Wheel Drive control panel is mounted on the right-hand
side of the cab in the door post. It contains all the controls and
warning lamps needed to operate the All Wheel Drive system.
The All wheel Drive System is activated by a rocker switch on the
front of the control panel (7).
Green lamps indicate system (1) and Creep mode activation (4).
The control panel has additional lamps that warn of excessive oil
temperature (5), low charge pressure (6), low oil level (2) and
clogged filter (3). These lamps alert you that a problem exists. Low
oil level and low charge pressure lamps are accompanied by an
audible alarm.
At the bottom of the control panel is the All Wheel Drive 16-posi-
tion aggression dial (9). This dial allows the operator to adjust the
power applied to the front wheels in comparison to the rear. For
further information on the operation of the All Wheel Drive system,
refer to Operating instructions, All Wheel Drive models page 91.
