Driving and operating125
It uses radar and camera sensors to
detect the vehicles ahead. If no
vehicle is detected in the driving path, the adaptive cruise control will
behave like a conventional cruise
control.
The adaptive cruise control
automatically decelerates the vehicle
when approaching a slower moving
vehicle. It then adjusts the vehicle
speed to follow the vehicle ahead at
the selected following distance. The
vehicle speed increases or decreases
to follow the vehicle ahead, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
If the vehicle ahead accelerates or
changes lane, the adaptive cruise
control progressively accelerates the
vehicle to return to the stored set
speed. If the driver operates the turn
lights to overtake a slower vehicle, the
adaptive cruise control allows the
vehicle to temporarily approach the
vehicle ahead to help passing it.
However, the set speed will never be
exceeded.
The adaptive cruise control can store
set speeds over 30 km/h for manual
transmission. If the vehicle ahead is
moving too slowly and the selected
following distance cannot be
maintained anymore, a warning
chime is given and a message is
displayed in the Driver Information
Centre. The message prompts the
driver to take back control of the
vehicle. On vehicles with automatic
transmission, the system can brake
the vehicle until a full stop.9 Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the button
Ñ have priority over any adaptive
cruise control operation.
Switching on the system
Press w.
w is indicated in the Driver
Information Centre. The system is still not active.
132Driving and operatingAs a safety measure, do not use the
system if the brake lights are faulty.
Do not use the system if the front
bumper is damaged.
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles and
pedestrians directly ahead, when the
driver does not actively take action
either by manual braking or by
steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert.
Forward collision alert 3 135
Front pedestrian protection 3 137
Active emergency braking can be
deactivated in the vehicle
personalisation 3 77. If deactivated,
m illuminates in the instrument
cluster and a warning message is
displayed in the Driver Information
Centre. When ignition is switched on next time, system is activated.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.
9 Warning
The usage of a license plate
support may have an impact on
the proper operation of the radar
unit and may limit sensor
perfomance. Vehicles or
pedestrians driving or walking
ahead may not be detected by the
system.
Do not use a a license plate
support to ensure proper system
functionality.
Functionality
Depending on the vehicle
configuration and the detected
objects, there are several operational speed ranges.
On vehicles equipped only with front
camera, the active emergency
braking operates from 5 km/h to 80 km/h when a vehicle has been
detected.
On vehicles equipped with radar
sensor and front camera, the active
emergency braking operates from
5 km/h to 140 km/h when a vehicle
has been detected.
Active emergency braking only works when the seat belts of the front
passengers are fastened.
134Driving and operating9Warning
Smart 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 brakepedal and then apply the brakes
as needed.
Forward collision alert 3 135.
Front pedestrian protection 3 137.
System limitations In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to various
types of objects, i.e., traffic signs or
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.
In the following cases, active
emergency braking performance
might be limited:
● driving on winding or hilly roads
● detecting vehicles with a trailer, tractors, muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● the sensor in the windscreen or the radar unit behind the front
bumper are blocked by snow, ice,
slush, mud, dirt etc.
● the windscreen is damaged or affected by foreign objects, e.g.
stickers
the bumper is damaged or
affected by foreign objects, e.g.
license plate support
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.We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when towing a trailer or caravan
● when carrying long objects on roof bars or a roof rack
● when the vehicle is being towed with the engine running
● when the vehicle is fitted with snow chains
● when a spare wheel is fitted that is smaller than the other wheels
● before using an automatic car wash with the engine running
● before placing the vehicle on a rolling road in a workshop
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
● if the brake lights are not working
Fault
In case the system requires a service,
a message is displayed in the Driver
Information Centre.
146Driving and operatingSide blind spot alertSide blind zone alert assist helps to
avoid crashes due to unintentional
lane departures when an object is
detected within a specified blind spot zone.
The system displays a visual alert in
each exterior mirror, when detecting
objects that may not be visible in the
interior and exterior mirrors.
Side blind spot alert uses some of the
advanced parking assist sensors
which are located in the front and rear bumper on both sides of the vehicle.9 Warning
Side blind zone assistant system
is only a lane changing aid and does not replace driver vision.
Side blind zone assistant does not detect:
● Vehicles outside the side blind zones which may be rapidly
approaching.
● Pedestrians or animals.
● Non-moving objects, e.g. stationary vehicles, street
lights, road signs, etc.
Failure to use proper care when changing lanes may result in
damage to the vehicle, injury, or
death. Always check the outside
and rearview mirrors, glance over
your shoulder, and use the turn
signal before changing lanes.
