CONTROLS
Brake intervention
The warning prompts the driver to intervene.
While a warning is active, the maximum braking
force is used when the brake is applied. In order
to activate the Brake Assistant function, the
brakes must be applied sufficiently quickly and
forcefully.
If there is a risk of collision, the system may also
assist with brake intervention.
When the vehicle is traveling at a low speed, the
vehicle may come to a complete stop.
The brake intervention can be interrupted by
stepping on the accelerator pedal or by actively
moving the steering wheel.
The system's ability to detect objects may be
limited in some circumstances. Refer to the in‐
formation in this Owner's Manual regarding the
limitations of the system and actively intervene
as warranted.
