CONTROLS
Acute warning with braking function
An acute warning is displayed in the event of an
immediate danger of collision with a crossing ve‐
hicle.
Intervene in the case of an acute warning. If an
acute warning is provided, the system may pro‐
vide assistance, such as through automatic brake
intervention, when there is risk of collision.
Acute warnings may be provided even when
there has been no prior warning.
Brake intervention
The warning prompts the driver to intervene.
The system may also assist in braking if there is
a risk of collision.
The vehicle can be decelerated to a standstill.
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.
