Automatic Level Control - GMC 2004 Yokon Denali Owner's Manual

CAUTION:
{
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
•
Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
•
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
•
Do not leave an unsecured child restraint
in your vehicle.
•
When you carry something inside the
vehicle, secure it whenever you can.
•
Do not leave a seat folded down unless
you need to.
There's also important loading information for off-road
driving in this manual. See "Loading Your Vehicle
for Off-Road Driving" under Operating Your
All-Wheel-Drive Vehicle Off Paved Roads on page 4-17.

Automatic Level Control

The automatic level control rear suspension comes as a
part of the Autoride™ suspension. See Autoride™ on
page 4-54.
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
10 minutes after the ignition key has been turned to
OFF. You may hear the air compressor operating when
the height is being adjusted.
If a weight-distributing hitch is being used, it is
recommended to allow the shocks to inflate, thereby
leveling the vehicle prior to adjusting the height.
