Operator Controls
The dash­mounted Operator Control Panel is the sole interface for
display of operator information and for key entry of system instructions.
Figure 3 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 re­inflate 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.
