180Driving and operatingForward collision alert 3 178
Front pedestrian protection 3 182
The feature uses various inputs (e.g.
camera sensor, brake pressure,
vehicle speed) to calculate the
probability of a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system may not react to
animals. After a sudden lane
change, the system needs a
certain time to detect the next
preceding vehicle.
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
Functionality
Active emergency braking is
equipped with a front camera and
operates in forward gear in the range
between walking speed and 53 mph.
The system detects stationary
vehicles only if the speed does not
exceed 50 mph.
A precondition is that active
emergency braking is not deactivated
in the vehicle personalisation menu
3 115.
If deactivated, m illuminates in the
instrument cluster and a warning message is displayed in the Driver
Information Centre
If the system has been deactivated
manually, it is reactivated
automatically the next time the
ignition is switched on.
The system includes: ● emergency automatic braking● forward collision alert
● front pedestrian protectionEmergency automatic braking
After activation of brake preparation
system and just before the imminent
collision, this function automatically
applies limited braking to reduce the
impact speed of the collision or
prohibit a crash.
If active emergency braking is
applied, m flashes in the instrument
cluster.
Depending on the situation, the
vehicle may automatically brake
moderately or hard.
Front automatic braking can only
occur if a vehicle or a pedestrian
ahead is detected.
Forward collision alert 3 178
Front pedestrian protection 3 182
Below a speed of 19 mph, emergency automatic braking may slow down thevehicle to a complete stop. If the
speed exceeds 19 mph, emergency
automatic braking reduces the speed.
However, the driver must apply the
brake.
