Driving and operating139Driver 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 25 mph.
Additionally at least the third gear
must be engaged on manual
transmission.
Additionally position D or the second
or a higher gear in position M must be
selected on automatic transmission.
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 firmly.
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.

Press m on the steering wheel:
symbol m and a message are
indicated in the Driver Information
Centre. The system is still not active.
144Driving and operatingFault
In the event of a speed limiter fault, the speed is cleared resulting in
flashing of the dashes.
The speed limit recognition may not
operate correctly if traffic signs do not
comply with the Vienna Convention
on Road Signs and Signals.
Forward collision alert The forward collision alert may help toavoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera in the windscreen to
detect a preceding vehicle directly
ahead, in your path.
If a vehicle directly ahead is
approached too quickly, a warning
chime and alert in the Driver
Information Centre is provided.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.
Activation
Forward collision alert detects
vehicles and operates automatically
at all speeds above 3 mph and
53 mph. The system detects
stationary vehicles if the speed does
not exceed 50 mph.
Alerting the driver
The driver is warned by following
alerts:
● Symbol , illuminates and a
warning message is displayed in the Driver Information Centre
when the distance to the vehicle
ahead gets to small.
● Symbol , illuminates, a warning
message is displayed in the
Driver Information Centre and a
warning chime sounds, when a
collision is imminent and
immediate driver's action is
required.9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
Driving and operating145approaching 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.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.
Selecting the alert sensitivity
The alert sensitivity has to be set to
close, normal or distant in the vehicle personalisation menu 3 94.
The chosen setting will remain until it
is changed. The alert timing will vary
based on vehicle speed. The faster
the vehicle speed, the farther away
the alert will occur. Consider traffic
and weather conditions when
selecting the alert timing.
Deactivation The system can only be deactivated
by deactivating the active emergency
braking in the vehicle personalisation
3 94.
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
● driving in the dark
● weather limits visibility, such as fog, rain, or snow
● the sensor in the windscreen is blocked by snow, ice, slush, mud,dirt etc.
● the windscreen is damaged or affected by foreign objects, 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 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 or the front pedestrian protection
alert.
146Driving and operatingForward collision alert 3 144
Front pedestrian protection 3 148
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.
Functionality
Active emergency braking is
equipped with a front camera and
operates in forward gear above
walking speed up to 53 mph. The
system detects stationary vehicles
only if the speed does not exceed
50 mph.
A precondition is that forward collision
alert with front camera system is not
deactivated in the vehicle
personalisation menu 3 94.
The system includes: ● emergency automatic braking● forward looking brake assist
● forward collision alert
● front pedestrian protection
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. If active emergency
braking is applied, m flashes in the
instrument cluster. Depending on thesituation, the vehicle may
automatically brake moderately or
hard. This front automatic braking can
only occur if a vehicle or a pedestrian ahead is detected.
Forward collision alert 3 144
Front pedestrian protection 3 148
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 emergency automatic
braking, the forward looking brake
assist function makes the brake assist
Driving and operating147more 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
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.

Front pedestrian protection 3 148.
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 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.
In the following cases, active
emergency braking performance is limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving in the dark
● windscreen damaged or stickeredComplete 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 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 lamps are not working
Active emergency braking can be
deactivated in the personalisation
menu 3 94. If deactivated, m

Parking assist
General information The system is switched off
automatically when attaching a trailer
or bike carrier to the trailer hitch.9 Warning
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 parking assist makes parking easier by measuring the distance
between the vehicle and obstacles. It
informs and warns the driver by giving acoustic signals and display
indication.
Acoustic signals are given on the side
on which the vehicle is closer to an
obstacle. 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.
Rear parking assist
The system operates with ultrasonic
parking sensors in the rear bumper.
Activation
Rear parking assist is activated when reverse gear is engaged.
The system is ready to operate when
the LED in the parking assist button
¼ is not illuminated.
Indication
The system warns the driver with acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
50 cm.
Additionally, the distance to rear
obstacles is displayed by changing
distance lines in the Info Display
3 90 . When the obstacle is very close,
9 for danger is displayed in the
screen.
150Driving and operatingDeactivation
The system is switched off when
reverse gear is disengaged. Press ¼
to deactivate the system manually.
The LED in the button illuminates
when the system is deactivated. If the
system has been deactivated
manually, it is not reactivated
automatically the next time the
ignition is switched on.
Front-rear parking assist
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.
The system operates with ultrasonic
parking sensors in the rear and front
bumper.
Activation
Rear parking assist is activated when reverse gear is engaged.
In addition to the rear parking assist,
the front parking assist is triggered
when an obstacle is detected in front
and the speed of the vehicle is still
below 6 mph.
The system is ready to operate when
the LED in the parking assist button
¼ is not illuminated.
Indication
The system warns the driver with acoustic signals against potentially
hazardous obstacles in front of the
vehicle and behind the vehicle by using the respective loudspeakers.
Additionally, the distance to rear and
front obstacles is displayed by
changing distance lines in the Info Display 3 90.
152Driving and operatingAdvanced parking assist9Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
the advanced parking assist.
The advanced parking assist
measures a suitable parking slot
while passing, calculates the
trajectory and automatically steers
the vehicle while parking.
Advanced parking assist provides
assistance for the following
manoeuvres:
● entry into a parallel parking slot
● entry into a perpendicular parking
slot
● exit from a parallel parking slot
The driver must control acceleration, braking and gear shifting, while
steering is done automatically. The driver can take control at any time by
gripping the steering wheel.
It may be necessary to move forwards and backwards more than once.
Instructions are given in the Info
