168Driving and operatingapproaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
System limitations
Forward collision alert is designed to warn about vehicles only, but may
react also to other objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● on winding roads
● when weather limits visibility, such as fog, rain, or snow
● when the sensor is blocked by snow, ice, slush, mud, dirt,
windscreen damage or affected
by foreign items, e.g. stickers
Following distance
indication
The following distance indication
displays the distance in seconds to a
preceding moving vehicle. The front
camera in the windscreen is used to
detect the distance of a vehicle
directly ahead in the vehicle's path. It
is active at speeds above 8 km/h.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre.
Select Information menu via steering
wheel buttons and press G to select
following distance indication 3 82.
The minimum indicated distance is
0.5 seconds.
If there is no vehicle ahead or the vehicle ahead is out of range, two
dashes will be displayed: -.- sec.
Active emergency braking
Active emergency braking can help toreduce the damage and injury from
crashes with vehicles, pedestrians and obstacles directly ahead, when a
collision can no longer be avoided
either by manual braking or by
steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert 3 166 and front pedestrian
protection 3 171.
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
Driving and operating171● if the windscreen has beendamaged close to the camera
● if the front bumper has been damaged
The system is reactivated the next
time the vehicle is switched on.
System limitations In some cases, the active emergencybraking system may provide
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs
in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
a service. Firmly apply the accelerator pedal if the situation and
surroundings permit to override the
automatic braking.In the following cases, active
emergency braking performance is
limited:
● When driving on winding or hilly roads.
● When not all vehicles are detected, especially vehicles witha trailer, tractors, muddy
vehicles, etc.
● When detecting a vehicle when weather limits visibility, such as infog, rain, or snow.
● During nighttime driving.
● When weather limits visibility, such as fog, rain, or snow.
● When the sensor in the windscreen is blocked by snow,
ice, slush, mud, dirt, windscreen
damage or affected by foreign
items, e.g. stickers.
To avoid malfunction keep the areas
of the camera sensor in the
windscreen always clear of dirt, dust,
ice and snow.Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.
Fault
In case the system requires a service, a message is displayed in the Driver
Information Centre.
If the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.
Vehicle messages 3 89.
Front pedestrian protection The front pedestrian protection
system may help avoid or reduce the
harm caused by front-end crashes
with nearby pedestrians when driving in a forward gear.
The system uses the front camera in the windscreen to detect a pedestrian
directly ahead in your path.
Driving and operating173Automatic brakingIf a crash into a pedestrian directly
ahead is imminent and the brakes
have not been applied, the braking
strength is automatically adapted.
This can help to avoid some very low speed pedestrian crashes or reduce
pedestrian injury.
Automatic braking levels may be
reduced under certain conditions, such as higher speeds.
If this happens, automatic braking
may engage the electric parking
brake to hold the vehicle at a stop.
Release the electric parking brake. A
firm press of the accelerator pedal will
also release automatic braking and
the electric parking brake 3 158.
This system includes intelligent brake
assist, and the emergency automatic
braking system may also respond to
pedestrians.
Active emergency braking 3 168.
Automatic braking can be disabled
through vehicle personalisation 3 90.General information9 Warning
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
9 Warning
Front pedestrian braking may alert
or automatically brake the vehicle
suddenly in situations where it is
unexpected and undesired. It
could falsely alert or brake for
objects similar in shape or size to
pedestrians, including shadows.
This is normal operation and the
vehicle does not need a service.
To override Automatic braking,
firmly depress the accelerator
pedal, if it is safe to do so.
System limitations
In the following cases, front
pedestrian protection may not detect
a pedestrian ahead or sensor
performance is limited:
● When vehicle speed is out of range from 8 km/h to 80 km/h .
● When the distance to an pedestrian ahead is more than
40 m.
● When weather limits visibility, such as fog, rain, or snow.
● During nighttime driving.
● When the sensor in the windscreen is blocked by snow,
ice, slush, mud, dirt, windscreen
damage or affected by foreign
items, e.g. stickers.
Parking assist
Rear parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
174Driving and operatingThe rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals
and display indication.
The system has three ultrasonic
parking sensors in the rear bumper.
Activation
After the vehicle is switched on, the
rear parking assist is activated.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
50 cm while a forward gear is
engaged, or up to 1.5 m while reverse gear is engaged.
Depending on which side of the
vehicle is closer to an obstacle, you
will hear acoustic warning signals in the vehicle on the respective side.
The interval between the sounds
becomes shorter as the vehicle gets closer to that obstacle. When the
distance is less than approx. 30 cm, the sound is continuous.
Additionally, the distance to rear
obstacles is displayed by changing
distance lines in the Driver
Information Centre 3 82.
The distance indication can be
inhibited by vehicle messages with a
higher priority. After dismissing the
message, distance indication
appears again.Deactivation
Press parking assist button r to
deactivate, the LED in the button
extinguishes.
Fault
In the event of a fault or if the system does not work temporarily, e.g.
because of high external noise level
or other interference factors, the LED
in the button flashes for 3 seconds
and then extinguishes. A message is
indicated in the Driver Information
Centre.
Driving and operating175Front-rear parking assist9Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
The front-rear parking assist
measures the distance between the vehicle and obstacles in front and
behind the vehicle. It informs and
warns the driver by giving acoustic
signals and display indication.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.The system has four ultrasonic
parking sensors in front bumper and three ultrasonic parking sensors in
the rear bumper.
Activation
The system is activated automatically
at a speed up to 11 km/h.An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
If r is switched off, the front parking
assist is deactivated until the vehicle
is switched on again.
If vehicle speed has exceeded
25 km/h beforehand, parking assist
will be reactivated when speed drops below 11 km/h.
When the system is deactivated, the
LED in the button extinguishes and a message pops-up in the Driver
Information Centre.
Driving and operating177trajectory and automatically steers
the vehicle into a parallel or
perpendicular parking slot.
Instructions are given in the Driver
Information Centre 3 82 or,
depending on the version, on the Info
Display 3 85, supported by acoustic
signals.
The driver must control acceleration,
braking and gear shifting, while
steering is done automatically.
Advanced parking assist is always
combined with front-rear parking assist. Both systems use the same
sensors in the front and rear bumper.
The system has six ultrasonic parking sensors in the front bumper and five
ultrasonic parking sensors in the rear
bumper.
Activation of advanced parking assist
Advanced parking assist can only be
activated when driving forwards.
When searching for a parking slot, the
system is ready to operate with a
