Control Mode

HINT:

This mode is used to check the operation of the pre-collision system when reproducing situations when the pre-collision system operated unnecessarily.

Operating the pre-collision brake assist control or pre-collision braking control when reproducing problem symptoms may lead to a dangerous situation. To avoid this, do not attempt to operate the pre-collision braking control, only operate the pre-collision warning control (buzzer and warning message) when reproducing the problem symptoms.
