Note:If the vehicle does not slow down to below the programmed
speed limit, the tires will automatically inflate to the appropriate
higher terrain setting. Once the higher terrain setting has been
achieved, the OVERSPEED light will stop flashing and the buzzer will
stop.
²Solid:The CTIS is not receiving any speed signals.

significant air system leak is detected.

TERRAIN
Allows the driver to select different
tire pressures and vehicle
parameters for unique driving
surfaces/conditions by adjusting tire
pressure. Selecting a terrain setting
will cause the system to run a
pressure check and adjust tire
pressure appropriately. Any terrain
may be selected at any time (within
speed limitations).
Note:When in ªHYº mode,
additional increments do not change tire pressures, but do cause a
pressure check.
Note:When in ªEº mode, additional decrements do not change tire
pressures, but do cause a pressure check.

LOAD
Allows the driver to select loaded or
unloaded tire pressures under
specified conditions. Selecting the
load setting will cause the system to
run a pressure check and adjust tire
pressure appropriately. The LOAD
setting can be changed any time
(within specified speed/load
limitations).
Automatic load sensing
²Vehicle load condition will be automatically sensed and tire pressure
adjusted, if necessary, when starting the engine and when the vehicle
is at a complete stop.
²Unloaded/Loaded tire pressures are available for each terrain
selection.
²Anytime the load can't be accurately sensed, the system will default to
the loaded tire pressure.
²Load settings are indicated by the bar graph on the DDM.

Tire pressure maintenance
The CTIS is set to check tire pressure every 15 minutes. The wheel
valves will automatically isolate the tires from the rest of the system; this
prevents a decrease in tire pressure due to fitting and seal leaks.
Some clicking may be heard as the system activates to achieve a new tire
pressure. Adequate supply system air pressure is required to begin or
continue any pressure change.
The system is designed to allow tire pressure increases due to heat
build-up during vehicle use. The system will not deflate the pressure
build-ups, a lower pressure mode selection must be made to decrease
the tire pressure.
Flat tire/Tire leak detection
If the CTIS detects a significantly low tire, the system will display a
ªCHECK TIREº message, sound a buzzer and automatically attempt to
inflate the tire(s) to the selected mode pressure. The ªCHECK TIREº
message and buzzer will stay on until the tire is inflated to the selected
mode pressure.
