General information
9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
Driving and operating169supplemental 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
a forward gear above walking speed
up to 80 km/h.
A precondition is that the system is
not deactivated in the vehicle
personalisation menu 3 90.
The system includes: ● brake preparation system
● emergency automatic braking ● forward looking brake assist
● front pedestrian protection system
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.
The brake system is prepared so that
braking can occur more rapidly.
If equipped only with front camera the system operates up to a speed of
80 km/h.
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
prevent a crash.
Depending on the situation, the
vehicle may automatically brake
moderately or hard. This front
automatic braking can only occur if a
vehicle ahead is detected, indicated
by the vehicle ahead indicator A
3 166. On vehicles with frontpedestrian protection, automatic
braking can also occur when a
pedestrian ahead is detected,
indicated by the pedestrian ahead
indicator 7.
The system operates up to a speed of
80 km/h.
Below a speed of 40 km/h the system can apply full braking.
Emergency automatic braking may slow the vehicle to a complete stop to
try to avoid a potential crash. If this
happens, emergency automatic
braking may engage the electric
parking brake to hold the vehicle at a
stop. To release, push the electric
parking brake switch or firmly depress the accelerator pedal.9 Warning
Emergency automatic braking is
an emergency crash preparation
feature and is not designed to
avoid crashes. Do not rely on the
system to brake the vehicle.
Emergency automatic braking will
170Driving and operatingnot brake outside of its operatingspeed range and only responds to
detected vehicles.
Forward looking brake assist
In addition to the brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. Therefore,
depressing the brake pedal less
strongly results in immediate hard
braking. This function helps the driver
brake quicker and harder before an
imminent collision.
The system operates up to a speed of 80 km/h.
9 Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is designed to reduce the vehicle
speed before a collision. It may not
react to animals. After a sudden
lane change, the system needs a
certain time to detect the next
preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the brakes and steer to avoid
collisions.
Intelligent brake assist
Intelligent brake assist may activate
when the brake pedal is applied
quickly by providing a boost to
braking based on the speed of
approach and distance to a vehicle
ahead.
Minor brake pedal pulsations or pedal movement during this time are normal and the brake pedal should continue
to be applied as required. Intelligent
brake assist will automatically
disengage only when the brake pedal is released.
9 Warning
Intelligent brake assist may
increase vehicle braking in
situations when it may not be
necessary. You could block the
flow of traffic. If this occurs, take
your foot off the brake pedal and
then apply the brakes as needed.
Front pedestrian protection
Front pedestrian protection 3 171.
Deactivation Active emergency braking can be
deactivated in the personalisation
menu in the Info Display 3 90.
If deactivated, a message is
displayed in the Driver Information
Centre.
We recommend to deactivate the system in the following cases:
● when the vehicle is being towed
● before using an automatic car wash with ignition switched on
Driving and operating191Activation
The lane keep assist is activated by
pressing a. The LED in the button
illuminates to indicate that the system
is switched on.
When the control indicator a in the
instrument cluster illuminates green,
the system is ready to assist.
The system is operational at vehicle
speeds above 60 km/h and if lane
markings are available.
The system gently turns the steering
wheel and the control indicator a
changes to yellow, if the vehicle
approaches a detected lane marking
without using the turn light in that
direction.
The system alerts by flashing a
together with three chimes, from the respective direction, if the lane is
departed significantly.
The system is only operable when a
lane marking is detected.
If the system only detects lane
markings on one side of the road, it
will only assist for this side.
Lane keep assist detects hands-free
driving. In this case a message in the
Driver Information Centre pops-up
and a chime sounds as long as lane
keep assist detects hands-free
driving.
Always take the steering wheel while
driving. Both the driving manner and
the road condition may affect thetiming of alert and the occurrence of
alert. Move the steering wheel to stop
the alert.
Deactivation The system is deactivated by
pressing a. The LED in the button
extinguishes.
The system is reactivated the next
time the vehicle is switched on.
Fault The system performance may beaffected by:
● windscreen not clean or affected by foreign items, e.g. stickers
● close vehicles ahead
● banked roads
● winding or hilly roads
● road edges
● roads with poor lane markings
● sudden lighting changes
● adverse environmental conditions e.g. heavy rain or
snow
● vehicle modifications, e.g. tyres
