snow chains KIA CARNIVAL 2007 Workshop Manual

2007 > 2.7L V6 GASOLINE >
Description
The VRS (Variable Rack Stroke) is the system that controls the rack stroke using the operating unit installed on both
ends of the gear box. Normally the VRS system keeps switching OFF and the rack stroke stays increased, so the
vehicle's turning radius becomes reduced. On the other hand, when fitting the snow chains in winter season, the VRS
switch must be turned ON and the VRS system will prevent interference between the snow chains and the vehicle by
decreasing the rack stoke.
Operating principle
When switching the VRS system ON, the DC motor in the VRS operating unit rotates the gear stopper by 90 degrees
and the gear stopper stops the stop protrusion from entering as shown in the illustration below. This operation reduces
the maximum steering angle by decreasing the rack stroke. When switching the VRS system OFF, the gear stopper
returns to original location and the rack stroke also returns to normal.
