Operator Instructions
Driver Display Module—Operator Controls
Load Selection
Vehicle load selection is represented by a horizontal bar graph
under the mode display. Depress the load rocker switch to
change the selection, up for increasing load and down for
decreasing load.
Operating a loaded vehicle at unloaded tire pressures may
result in tire overheating and reduced tire life or blowout.
Terrain Selection
The terrain selection is changed by depressing the terrain
rocker switch, up to increase pressures and down to decrease
pressures. Any switch operation which does not change pres-
sures will command the system to do a pressure check.
Tire pressures for the following terrains can be programmed
and may be selected by the operator:
•
(HY) Highway
- For travel on paved surfaces at
higher speeds.
•
(CC) Cross Country
- For reduced speed operation
on secondary roads.
•
(SS) Mud Sand Snow
- For reduced speed operation
on unpaved surfaces.
•
(E) Emergency
- For selection of extremely low tire
pressures to help free a stuck vehicle.
The Emergency selection is for extreme conditions only and
should not be used for normal driving.
Display
The Driver Display Module (DDM) uses a multi-function dis-
play to indicate the current selections. The display will show
HY for highway pressures, CC for cross-country pressures,
SS for mud-sand-snow pressures, and E for emergency pres-
sures.
Note:
The system is designed to allow tire pressure increase
due to heat buildup during vehicle use. It will not auto-
matically deflate these pressure buildups.
Channel Indicators
The DDM indicates FRT or RR, respectively, for front or rear
axle groups. A flashing indicator identifies a group which is
changing or checking pressures. A solid indicator identifies a
group that has achieved target pressure.
Service Code Indication
The DDM will not display service codes directly but will dis-
play two dashes if service is required. (Accessing the service
codes requires a diagnostic tool). Also, a solid over speed
indicator identifies a loss of expected vehicle speed input.
