■ AVS (Adaptive Variable Suspension System) control (if equipped)
When the system determines that there is a high possibility of a colli-
sion, the AVS optimizes the damping effect (P. 319)
■ Driver monitor system (if equipped)
When the system determines that there is a possibility of a collision,
and the driver is not facing forward, PCS warnings are given in
advance to warn the driver. If the driver continues to be not facing
forward, and a probable collision is detected, PCS informs the
driver of danger by performing slight braking to provide a physically
warning (pre-collision alert braking). (P. 343)
