Dodge 2004 RS Caravan - Manual (Page 142)

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 lev-
eling system will render this system ineffective,
inappropriately reducing rear brake pressure, result-
ing in increased stopping distances. You could have
an accident.
