Warning with braking function
Display
A warning symbol appears in the instrument
cluster and in the Head-up Display, where availa‐
ble, if a collision with a detected vehicle is immi‐
nent.
Icon Measure
Icon lights up red: prewarning.
Brake and increase distance.
Symbol flashes red and an acoustic
signal sounds: acute warning.
Brake and make an evasive maneuver,
if necessary.
Prewarning
This warning is provided, for instance when there
is impending danger of a collision or the distance
to the vehicle ahead is too small.
If a prewarning is provided, respond by braking
as warranted.
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
speed.
Intervene in the case of an acute warning. De‐
pending on the driving situation and the equip‐
ment version, the acute warning may be accom‐
panied 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 auto‐
matic 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. 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‐
fully.
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 brake intervention occurs
to up to approx. 50 mph/80 km/h.
With radar sensor: the brake intervention occurs
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 braking pres‐
sure. No automatic delay occurs.
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.
