218 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
LOAD-LEVELING SYSTEM — IF EQUIPPED
The automatic load-leveling system will provide a level
riding vehicle under most passenger and cargo loading
conditions.
A hydraulic pump contained within the shock absorbers
raises the rear of the vehicle to the correct height. It takes
approximately 1 mile (1.6 km) of driving for the leveling
to complete depending on road surface conditions.
If the leveled vehicle is not moved for approximately 15
hours, the leveling system will bleed itself down. The
vehicle must be driven to reset the system.
WARNING!
Do not install the load-leveling system on vehicles
that are not equipped with Anti-Lock Brakes. Ve-
hicles without Anti-Lock Brakes (ABS) have a height-
sensing proportioning valve. Installing a leveling
system will render this system ineffective, inappro-
priately reducing rear brake pressure, resulting in
increased stopping distances. You could have a seri-
ous accident.
