194Driving and operating
If Adaptive cruise control is active,
this page shows the alert sensitivity
setting instead of following distance setting 3 181.
System limitations
In the following cases, following
distance indication sensor
performance is limited:
● Driving on winding or hilly roads.
● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow.
● The sensor is blocked by snow, ice, slush, mud, dirt, windscreen
damage or affected by foreign
items, e.g. stickers.
Active emergency braking Active emergency braking is part of
the forward collision system 3 123. It
can help to reduce 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 3 190 or the Front pedestrian
protection alert 3 197.
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's 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
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist
● intelligent brake assist (only with radar sensor)
● front pedestrian protection system
196Driving and operating9Warning
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.
The system is designed to work with
all occupants wearing their seat belts.
Intelligent Brake Assist
If the vehicle is equipped with radar
sensor 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 is normal
and the brake pedal should continue
to be applied as needed. 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 3 197.
Deactivation Active emergency braking can be
deactivated in the personalisation
menu 3 123. If deactivated a
message is displayed in the Driver
Information Centre.
We recommend to deactivate the
system or set it to alert only in the
following cases:
● when the vehicle is being towed
● if a trailer is attached to the vehicle
● before using an automatic car wash with ignition switched on
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
System limitations In some cases, the active emergency
braking system may provide an
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
service. Firmly apply the accelerator
pedal to override the automatic
braking if the situation and the
surroundings permit.
Driving and operating207The system may not operate properly
when:
● Ice, snow, mud, stickers, magnets, metal plates, or
anything else covers the sensors.
● Driving in heavy rainstorms. ● The vehicle had an accident or if the area surrounding the
detection sensor is damaged or
not properly repaired.
● There are extreme temperature changes.
● The vehicle is towing a trailer
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.
Note
Each new vehicle requires a
calibration. For optimal
performance, drive as soon as
possible on a straight motorway
road with roadside objects, e.g.
guardrails and barriers for some
distance.Lane change alert
Additional to the side blind spot alert3 206, lane change alert recognises
rapidly approaching vehicles from
behind on parallel lanes next to your
vehicle.
The system alerts visually in each
exterior mirror when detecting rapidly
approaching vehicles from behind.
The radar distance sensors are
located in the rear bumper.9 Warning
Lane change alert does not
replace driver vision.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn light.
When the system detects an
approaching vehicle from behind
which drives considerably faster, the
yellow warning symbol F will
illuminate in the relevant exterior mirror. If the driver then activates the
turn lights, the warning symbol F
starts flashing yellow as a warning not to change lanes.
Lane change alert is active at all
speeds.
When the vehicle is started, both
exterior mirror displays will briefly come on to indicate that the system is operating.
208Driving and operatingDetection zones
The system sensors cover a zone of
approx. 3.5 m parallel on both vehicle
sides and approx. 3 m rearwards on
side blind zone alert (A) and approx.
50 m rearwards on lane change alert (B) on parallel lanes. The zones start
at each exterior mirror. The height of
the zone is approx. between 0.5 m
and 2 m off the ground.
Deactivation Activation or deactivation of the lane
change alert can be set in the vehicle personalisation menu in the Info
Display.
Vehicle personalisation 3 123.
Info Display 3 117.
Deactivation is indicated by a
message in the Driver Information
Centre.
System limitations
Occasional missed alerts can occur
under normal circumstances or in
sharp curves. The system can
temporarily alert of objects in the blind spot at specific weather conditions
(rain, hail etc). Driving on a wet road
or in the transitions from a dry area to a wet area can cause the control
indicator F to light up, as water
splash can be interpreted as an object. Otherwise the control indicator
F may illuminate due to guardrails,
signs, trees, shrubs or other immobile
objects. This is normal operation and
the system does not need to be
serviced.The system may not operate properly
when:
● ice, snow, mud, stickers, magnets, metal plates, or
anything else covers the sensors
● driving in heavy rainstorms
● the vehicle had an accident or if the area surrounding the
detection sensor is damaged or
not properly repaired
● there are extreme temperature changes
● the vehicle is towing a trailer
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.
Note
Each new vehicle requires a
calibration. For optimal
performance, drive as soon as
possible on a straight motorway road with roadside objects, e.g.
guardrails and barriers for some
distance.
212Driving and operatingGuidelines

The system is intended to help thedriver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane keep assist
Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
observes the lane markings between
which the vehicle is driving. If the
vehicle approaches a lane marking, the steering wheel is gently turned to
position the vehicle back into the lane. Turn steering wheel in same
direction, if system steering is not
sufficient. Turn steering wheel gently
into opposite direction, if lane change is intended.
When crossing a lane marking
significantly, lane keep assist starts a
visual and acoustic warning.
Additionally, the status of the lane
keep assist is indicated on the Driver
Assistance page in the Driver
Information Center 3 111.
Unintended lane departure is
assumed
● without using turn lights● using the turn lights in the opposite direction of the lane
departure
● without braking
● without acceleration
● without active steering.
