warning may be accompanied by a brief acti-
vation of the braking system.
With the warning time setting "Late" the brief
activation of the braking system is omitted.
If an acute warning is provided, the system
may also provide assistance such as through
automatic brake intervention when there is risk
of collision.
Acute warnings may be provided even when
there has been no prewarning.
Brake intervention
The warning prompts the driver to intervene.
When the brake pedal is depressed quickly and
hard, the maximum brake power of the vehicle
is used.
The system may also assist with brake inter-
vention if there is a risk of collision.
When the vehicle is traveling at a low speed,
the vehicle may come to a complete stop.
Manual transmission: during a brake interven-
tion up to a complete stop, the engine may be
shut down.
City brake function: the brake intervention oc-
curs to up to approx. 50 mph/80 km/h.
With radar sensor: the brake intervention oc-
curs to up to approx. 155 mph/250 km/h.
At speeds above approx. 130 mph/210 km/h,
the brake intervention occurs as a brief activa-
tion of the braking system. No automatic delay
occurs.
The braking intervention can be interrupted by
stepping on the accelerator pedal with suffi-
cient force or by actively moving the steering
wheel.

Safety information
Warning
Due to its limits, the system may not react, or
it may react too late or in a manner that is not
consistent with normal use. There may be a
risk of accidents or risk of damage to prop-
erty. Actively intervene as warranted. Refer
to the information in this Owner's Manual re-
garding the scope of the system's operation
and limitations.
Detection range
The system's detection capability is limited.
Only objects that are detected by the system
are taken into account.
Thus, a system response might not come or
might come late.
The following situations may not be detected,
for instance:
▷ Vehicle driving slowly in front and being ap-
proached at high speed.
▷ Vehicles that suddenly swerve in front of
you, or strongly decelerating vehicles.
▷ Vehicles with unusual rear designs.
▷ Two-wheeled vehicles ahead of you.
Upper speed limit
