170Driving and operatingeither by manual braking or by
steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert or the front pedestrian protection alert.
Forward collision alert 3 168
Front pedestrian protection 3 173
Active emergency braking can be
deactivated in the personalisation
menu 3 104. If deactivated, m
illuminates in the instrument cluster
and a warning message is displayed
in the Driver Information Centre.
The feature uses various inputs (e.g.
camera sensor, radar 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
If equipped only with front camera the
active emergency braking operates in
forward gear above walking speed up
to 53 mph. With radar sensor and
front camera active emergency
braking operates in forward gear in
the range between walking speed
and 87 mph.
A precondition is that forward collision
alert with front camera system is not
deactivated in the vehicle
personalisation menu and the seat
belts of the front passengers are
fastened 3 104.
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist
● intelligent brake assist (only with radar sensor)
● forward collision alert
● front pedestrian protection
Brake preparation system
When approaching a vehicle ahead
or a pedestrian so quickly that a
collision is likely, the brake
preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or automatic braking is requested.
Emergency 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 ahead is
