Level Control

Automatic Level Control
The automatic level control rear suspension is
available on two-wheel drive and four-wheel drive
light-duty vehicles and comes as a part of the
®
Autoride suspension, if equipped.
This type of level control is fully automatic and will
provide a better leveled riding position as well
as better handling under a variety of passenger
and loading conditions. An air compressor
connected to the rear shocks will raise or lower
the rear of the vehicle to maintain proper vehicle
height. The system is activated when the
ignition key is turned to RUN and will automatically
adjust vehicle height thereafter. The system
may exhaust (lower vehicle height) for up to ten
minutes after the ignition key has been turned off.
You may hear the air compressor operating
when the height is being adjusted.
If a self-equalizing hitch is being used, it is
recommended to allow the shocks to inflate,
thereby leveling the vehicle prior to adjusting
the hitch.
