Locking Rear Axle; Continuous Damping Control (Cdc); Automatic Level Control - GMC 2011 Yukon Denali Owner's Manual

Locking Rear Axle

Vehicles with a locking rear axle can
give more traction on snow, mud,
ice, sand, or gravel. It works like a
standard axle most of the time, but
when traction is low, this feature will
allow the rear wheel with the most
traction to move the vehicle.
Continuous Damping
Control (CDC)
This vehicle may have a continuous
damping control system called
®
Autoride or MagneRide . With
this feature, improved vehicle ride
and handling is provided under a
variety of passenger and loading
conditions.
Autoride and MagneRide are fully
automatic and use 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 and MagneRide also
interact with the tow/haul mode
that, when activated, 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 under
for more
information.

Automatic Level Control

The automatic level control rear
suspension is available on light duty
vehicles and comes as a part of the

Continuous Damping Control (CDC)

suspension, if equipped.
Driving and Operating
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 ON/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 weight distributing hitch is being
used, it is recommended to allow
the shocks to inflate, thereby
leveling the vehicle prior to
adjusting the hitch.
