Introduction
The dash-mounted Operator Control Panel is the sole
interface for display of operator information and for key
entry of system instructions. Figure 39 shows the
Operator Control Panel. The following sections explain
the purpose and operation of all Operator Control Panel
features.
Warning Icons
The two warning icons report operating problems. You
must take immediate action to either reduce vehicle
speed or check tire condition.
Reduce Vehicle Speed – This signal
reports that the vehicle speed is too fast
for the pressure selected. You must
either reduce speed or select a higher
pressure by pressing the appropriate key. Continued
operation in this mode will result in the system auto-
matically selecting a more appropriate pressure setting.
Check Tire Condition – This signal
reports that one tire is at a significantly
lower pressure than the others and could
indicate that a tire is not holding pres-
sure. The operator should immediately stop the vehicle
and identify the extent of tire damage. The system may
be used to re-inflate the low tire if damage is deter-
mined to be minimal (e.g., a minor puncture or slow
leak) by selecting “RUN FLAT.” The system should not
be used to inflate tires with more substantial damage
such as large cuts, chunk outs, or structural defects.
