Symbol lights up red: prewarning.
Brake and increase distance.
Symbol flashes red and an acoustic
signal sounds: acute warning.
Brake and make an evasive maneu‐

to the vehicle ahead is too small.
If a prewarning is provided, respond by braking
Acute warning with braking function
An acute warning is displayed in case of the im‐
minent danger of a collision when the vehicle ap‐
proaches another object at a high differential
Intervene in the case of an acute warning. De‐
pending on the driving situation, the acute warn‐
ing may be accompanied by a brief activation of
the braking system.
With the warning time setting "late" the brief ac‐
tivation of the braking system is omitted.
If an acute warning is provided, the system may
also provide assistance, such as through braking,
when there is risk of collision.
Acute warnings may be provided even when
there has been no prior warning.
The warning prompts the driver to intervene. If a
warning is active, the maximum braking force is
used when the brake is applied. The brake pedal
must be applied sufficiently quickly and force‐
The system may also assist in braking if there is
a risk of collision.
When the vehicle is traveling at a low speed, the
vehicle may come to a complete stop.
City brake function: the braking intervention oc‐
curs to up to approx. 50 mph/80 km/h.
With radar sensor: the braking intervention oc‐
curs to up to approx. 155 mph/250 km/h.
At speeds above approx. 130 mph/210 km/h, the
braking intervention occurs as a brief braking
pressure. No automatic delay occurs.
