Driving and operating185Switching off the system
Turn to 0 to switch off the system. The
symbol 5 and a message are
displayed in the Driver Information
Centre.
Switching off the ignition deletes the
stored set speed.
Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it again.
● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that the
control of the vehicle can be lost.
● Do not use the system when the spare wheel is in use.
System limits9 Warning
The system's automatic brake
force does not permit hard braking and the braking level may not be
sufficient to avoid a collision.
● The control range is limited to a maximum deviation of 30 km/h
between the set speed and the
speed of the vehicle ahead.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles onlyat low speed.
● Do not use the adaptive cruise control when towing a trailer.
● Do not use the adaptive cruise control on roads with an incline ofmore than 10%.
Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may lose the current vehicle ahead or
consider a vehicle which is not in the
190Driving and operatingEmergency automatic braking may
slow the vehicle to a complete stop to
try to avoid a potential crash. If the
vehicle comes to a complete stop,
automatic braking is maintained for
up to 2 seconds.
● Automatic transmission: If the vehicle comes to a completestop, 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.
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 infog, rain, or snow.
● Driving during nighttime.
● The windscreen is damaged or affected by foreign items, e.g.
stickers.
Complete attention is always required
while driving, and the driver 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 tyre chains are fitted
● 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
192Driving and operating● the sensor in the windscreen isblocked by snow, ice, slush, mud,dirt etc.
● the windscreen is damaged or affected by foreign objects, e.g.
stickers
Parking assist
General information
When attaching a trailer or bicycle
carrier to the trailer hitch, the parking
assist is deactivated.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.
Rear parking assist
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
50 cm while reverse gear is engaged.
The system operates with ultrasonic
parking assist sensors in the rear
bumper.
Activation
Rear parking assist is activated when
reverse gear is engaged and ignition
is switched on. This is confirmed by a chime.Info Display without touchscreen
The system is ready to operate when
the LED in the parking assist button
é is not illuminated.Info Display with touchscreen
Activate the parking assist in the
vehicle personalisation 3 124.
Indication
Depending on which side of the
vehicle is closer to an obstacle,
acoustic warning signals in the
vehicle sound on the respective side.
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.
196Driving and operatingOperation conditions
The following conditions must be
fulfilled for proper operation:
● all vehicles are moving in the same direction and in adjacent
lanes
