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.
