Level Control; Autoride - GMC Chevrolet Tahoe 2003 Manual

Level Control

Automatic Level Control
The automatic level control rear suspension is available
on C/K 1500 vehicles and comes as a part of the
Autoride™ suspension.
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.

Autoride™

The Autoride™ feature will provide a superior vehicle
ride and handling under a variety of passenger and
loading conditions.
The system is fully automatic and uses a computer
controller to continuously monitor vehicle speed, wheel
to body position, lift/dive and steering position of the
vehicle. The controller then sends signals to each shock
absorber to independently adjust the damping level to
provide the optimum vehicle ride.
Autoride™ also interacts with the tow/haul switch that,
when engaged, will provide additional control of the
shock absorbers. This additional control results in better
ride and handling characteristics when the vehicle is
loaded or towing a trailer. See Tow/Haul Mode Light on
page 3-52 for more information.
