Locking Rear Axle; Continuous Damping; Control (Cdc); Automatic Level Control - Chevrolet Suburban 2014 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 . With this feature,
improved vehicle ride and handling
is provided under a variety of
passenger and loading conditions.
Autoride 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 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 Trailer
Towing on page 9-63 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.
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
Driving and Operating
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.
