Chevrolet avalanche 2002 ユーザーズマニュアル

The self

-

adjusting rear suspension is available on

C/K1500 vehicles and is available with 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 takes 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.

If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice, 
sand or gravel. It works like a standard axle most of the
time, but when one of the rear wheels has no traction
and the other does, this feature will allow the wheel with
traction to move the vehicle.

To sound the horn, press the center pad on the 
steering wheel.
