152Driving and operatingDriver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver stays in full control of
the vehicle and accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation and follow applicable
traffic rules.
Cruise control
The cruise control can store and
maintain speeds above 40 km/h.
Additionally at least the third gear
must be engaged on manual
transmission, on automatic
transmission position D or the second
or a higher gear in position M must be
selected.
Deviations from the stored speeds
may occur when driving uphill or
downhill.
The system maintains the vehicle
speed at the preset speed by the
driver, without any action on the
accelerator pedal.
The preset speed can be exceeded
temporarily by pressing the
accelerator pedal.
The status and preset speed is
displayed in the Driver Information Centre.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
Activating in first gear is not possible.
Control indicator m 3 95.Switching on
Press m on the steering wheel:
symbol m and Pause are indicated in
the Driver Information Centre. The
system is still not active.

Forward collision alert The forward collision alert may help to
avoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera in the windscreen to
detect a vehicle directly ahead, in
your path.
The system triggers different level of
alerts depending on the risk of
collision detected. The alerts are
displayed in the Driver Information
Centre.
Level 1: A visual alert is displayed.
Level 2: A visual alert is displayed and an audible alert sounds.Caution
The colour lighting of this control
indicator does not correspond to
local traffic laws on following
distance. The driver bears full
responsibility for maintaining safe
following distance according to
applicable traffic rules, weather
and road conditions etc. at all
times.9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching 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.
Page 159 of 257

Driving and operating157When the time to a potential collision
with a vehicle in front gets too small
and a collision is imminent, a warning
is displayed in the Driver Information
Centre.
Simultaneously a warning chime
sounds. Depress the brake pedal and
steer the vehicle, if it is required by the
situation.
Operation conditions The following condition must be
fullfilled for proper operation:
The speed must be between 5 km/h
and 140 km/h.
Activation To use forward colision alert, active
safety braking has to be activated in
the vehicle personalisation 3 103.
Selecting the alert sensitivity
The alert sensitivity has to be set to
close, normal or distant in the vehicle
personalisation menu 3 103.Deactivation
The system can only be deactivated
by deactivating the active emergency
braking in the vehicle personalisation
3 103.
System limitations Forward collision alert is designed to
warn on 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:
● Driving on winding or hilly roads.
● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow
● The windscreen is damaged or affected by foreign items, e.g.
stickers.
Active emergency braking
Active emergency braking can help to reduce the damage and injury from
crashes with vehicles, pedestrians
and obstacles directly ahead, when acollision 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 3 156 or the front pedestrian
protection alert 3 159.
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
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.

158Driving and operatingOperation conditions
Active emergency braking is
equipped with a front camera and
operates in forward gear above
walking speed up to 85 km/h.
Activation
Active emergency braking can be
activated in the vehicle
personalisation menu 3 103.
Functionality
The system includes: ● brake preparation system
● emergency automatic braking ● forward looking brake assist
● 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
pressurizes 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.
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. Depending on the
situation, the vehicle may
automatically brake moderately or
hard. This front automatic braking can
only occur if a vehicle 3 156 or a
pedestrian 3 159 ahead is detected .
Emergency automatic braking may slow the vehicle to a complete stop to
try to avoid a potential crash.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
not brake outside of its operating
speed range and only responds to
detected vehicles and
pedestrians.
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, pressing
the brake pedal less strongly results
in immediate hard braking. This
function helps the driver brake
quicker and harder before the
imminent collision.
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
