4-5. Using the driving support systems

Pre-collision warning

When the system determines that

the possibility of a frontal collision is

high, a buzzer will sound and a warn-

ing message will be displayed on the

multi-information display to urge the

driver to take evasive action.

When the system determines that the possibility of a frontal collision is high,

the system applies greater braking force in relation to how strongly the brake

pedal is depressed.

When the system determines that the possibility of a frontal collision is high,

the system warns the driver. If the system determines that the possibility of a

collision is extremely high, the brakes are automatically applied to help avoid

the collision or reduce the collision speed.

: Depending on the region in which the vehicle was sold, the pre-collision braking func-

tion may not be available.

Suspension control (if equipped)

When the system determines that the possibility of a frontal collision is high,

the Adaptive Variable Suspension System (P. 382) will control the damping

force of the shock absorbers.
