Drive away function
Vehicles with manual transmission:
Depressing the clutch pedal and then slightly releasing the clutch pedal and
slightly depressing the accelerator
pedal releases the electric parking
brake automatically. This is only
possible if the automatic operation of
the electric parking brake is activated. It is not possible when switch j is
pulled at the same time.
Vehicles with automatic transmission: Engaging R, D or M and then
depressing the accelerator pedal
releases the electric parking brake
automatically. This is only possible if

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.
Driving and operating131take action and depress the brake
pedal if you need to brake more
quickly.
Hill considerations9 Warning
Do not use the adaptive cruise
control on steep hill roads.
System performance on hills depends
on vehicle speed, vehicle load, traffic
conditions and the road gradient. It
may not detect a vehicle in your path
while driving on hills. On steep hills,
you may have to use the accelerator
pedal to maintain your vehicle speed.
When going downhill you may have to brake to maintain or reduce your
speed.
Note that applying the brake
deactivates the system.
Radar unit
The radar unit is located in the middle of the front bumper.
9 Warning
The radar unit was aligned
carefully during manufacture.
Therefore, in the event of a front-
end impact, do not use the system. The front bumper may appear to
be intact, however the sensor
behind may be affected and react
incorrectly. After an accident,
consult a workshop to verify and
adjust the radar unit position.
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 driving
ahead, pedestrians or other
objects located in front of the
vehicle may not be detected by the
system.
Do not use a license plate support on the front bumper to ensure
proper system functionality.
Fault
In the event of a fault with the adaptive cruise control, you are alerted by the
illumination of a warning light and the
display of a message in the
instrument panel, accompanied by an audible signal.
The adaptive cruise control may not
operate correctly if traffic signs do not
comply with the Vienna Convention
on Road Signs and Signals.
Have the system checked by a dealer or a qualified workshop.
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.
Driving and operating133The system includes:● brake preparation system
● emergency automatic braking
● smart 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
pressurises the brakes. This reduces
the response time, when braking is
requested.
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.Emergency automatic braking can
only occur if a vehicle or a pedestrian ahead is detected.
Forward collision alert 3 135
Front pedestrian protection 3 137
Below a speed of 30 km/h,
emergency automatic braking may
slow down the vehicle to a complete
stop. If the speed exceeds 30 km/h,
emergency automatic braking
reduces the speed. However, the
driver must apply the brake.
Emergency automatic braking may slow the vehicle to a complete stop to
try to avoid a potential crash.
● Automatic transmission: If the vehicle comes to a complete
stop, automatic braking is
maintained for up to two
seconds. Keep the brake pedal
depressed to prevent the vehicle
from starting off again.
● Manual transmission: If the vehicle comes to a complete
stop, the engine may stall.
Operation of the function may be felt
by a slight vibration in the brake
pedal.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.
Smart brake assist
Smart brake assist provides a boost
to braking when the brake pedal is quickly applied. The braking is 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.
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
