Air Suspension Height Control Switch
NOTICE
Do not operate the vehicle over uneven ground
such as ramps, speed bumps, curbs, etc. with
the air springs deflated. Doing this may lead to
air bag separation from the piston, preventing the
suspension air springs from re-inflating.
The air suspension height control switch is used to
adjust the vehicle height to aid in coupling or
uncoupling from a trailer. See
Fig. 4.22. Setting the
switch to LOWER deflates the air springs to lower
the rear of the vehicle. In the NORMAL position, the
air springs inflate to raise the rear of the vehicle to
normal ride height.
NOTICE
Never exhaust air from the suspension while
driving. When the air is exhausted, the
suspension will not absorb road shocks, and
components may be damaged.
A red LED in the switch is illuminated when the
suspension is deflated.
