Level Control - Chevrolet Avalanche 2004 Owner's Manual

Add-On Equipment
When you carry removable items, you may need to put
a limit on how many people you can carry inside
your vehicle. Be sure to weigh your vehicle before you
buy and install the new equipment.
Notice: Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
Remember not to exceed the Gross Axle Weight Rating
(GAWR) of the front or rear axle. See Loading Your
Vehicle on page 4-55.
The Cargo Weight Rating (CWR) is the maximum
weight of the load your vehicle can carry. It doesn't
include the weight of the people inside. But you
can figure about 150 lbs. (68 kg) for each seat.
The total cargo load must not be more than your
vehicle's CWR.

Level Control

Self-Adjusting
The self-adjusting rear suspension may come as part of
the premium smooth ride suspension package.
This type of level control will provide a leveled riding
position as well as improved handling under a variety of
passenger and loading conditions. A hydraulic pump
inside each rear shock absorber raises the rear of the
vehicle to the proper height, based on inputs from the
road surface, while the vehicle is being driven. It take
approximately 2 miles (3.2 km) of driving for the leveling
to complete, depending on the road surface conditions.
If the loaded vehicle is not moved for approximately
12 hours, the leveling system may bleed down to a lower
height. This can be especially apparent if a trailer is
left attached to a parked vehicle for long periods of time.
The vehicle must be driven to re-level the vehicle.
If a self-equalizing hitch is being used, the vehicle
should be driven approximately 2 miles (3.2 km) with the
trailer prior to adjusting (leveling) the hitch.
