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 and display
indication 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 sensors in the rear bumper.
Activation
Rear parking assist is activated when reverse gear is engaged and ignition
is switched on.
The system is ready to operate when
the LED in the parking assist button
¼ is not illuminated.
Indication
Depending on which side of the
vehicle is closer to an obstacle, you will hear acoustic warning signals inthe vehicle 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.
Additionally, the distance to rear
obstacles is displayed by changing
distance lines in the Info Display
3 101. When the obstacle is very
close, 9 for danger is displayed.

Lane departure warning
The lane departure warning system
observes the lane markings between which the vehicle is driving via a front camera located at the top of thewindscreen. The system warns the
driver in the event of an unintendend
lane departure via visual and acoustic signals.
There is no lane departure warning when the turn lights are operated and during 20 seconds after turn lights
have been switched off.9 Warning
This system is a driving aid that
cannot, in any circumstances,
replace the need for vigilance on
the part of the driver.
Activation
188Driving and operatingAfter ignition is switched on, the lane
departure warning system is
activated. If the system is activated,
the LED in the button ½ is not
illuminated. To activate the system
when the system is deactivated,
press ½.
The system is only operable at
vehicle speeds above 37 mph and if
lane markings are available.
When the system recognises an
unintended lane departure, the
control indicator ) flashes yellow.
Simultaneously a chime sound is
activated.
Deactivation
To deactivate the system, press andhold ½. The LED in the button is
illuminated and ½ illuminates yellow in
the instrument cluster.
At speeds below 37 mph the system
is inoperable.
Fault
In the event of a fault, H appears
in the instrument panel, accompanied
by a display message and a warning
chime. Contact a dealer or a qualified
workshop to have the system
checked.
System limitations The system performance may notoperate properly when:
● Vehicle speed is below 37 mph.
● Windscreen is not clean or affected by foreign objects, e.g.
stickers.
● Driving on winding or hilly roads.
● During nighttime driving.
● Adverse environmental conditions like heavy rain, snow,
direct sunlight or shadows.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,dirt, windscreen damage or
affected by foreign objects, e.g.
stickers.● The sun is shining directly into the camera lens.
● Close vehicles ahead.
● Driving on banked roads.
● Driving on road edges.
● Driving on roads with poor lane markings.
● Sudden lighting changes.
The system can not operate when no
lane marking is detected.
Lane keep assist
Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
observes the lane markings between
which the vehicle is driving. If the
vehicle approaches a lane marking, the steering wheel is gently turned to
position the vehicle back into the lane. The driver will then notice a turning
movement of the steering wheel. Turn steering wheel in same direction, if
system steers not sufficient. Turn steering wheel gently into opposite
direction, if lane change is intended.
190Driving and operatingthe correction. A warning message inthe Driver Information Centre
accompanied by a warning chime
alerts the driver when immediate
driver´s action is required.
Deactivation To deactivate the system, press andhold Ó. Deactivation of the system is
confirmed by the illuminated LED in
the button. In the Driver Information
Centre solid grey lines are displayed.
Fault
In the event of a fault, a and H
appear in the instrument panel, accompanied by a display message
and a warning chime. Contact a
dealer or a qualified workshop to have the system checked.
System limitations The system performance may be
affected by:
● windscreen not clean or affected by foreign objects, e.g. stickers
● close vehicles ahead
● banked roads● winding or hilly roads
● road edges
● sudden lighting changes
● adverse environmental conditions, e.g. heavy rain or
snow
● vehicle modifications, e.g. tyres
Switch off the system if the system is
disturbed by tar marks, shadows,
road cracks, temporary or
construction lane markings, or other
road imperfections.9 Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert,
even if a lane marking is detected.
The steering of the lane keep
assist may not be sufficient to
avoid a lane departure.
The system may not detect hands-
off driving due to external
influences like road condition and
surface and weather. The driver has full responsibility to control the vehicle and is always required to
keep the hands on the steering
wheel while driving.
Using the system while towing a
trailer or on slippery roads could
cause loss of control of the vehicle
and a crash. Switch the system off.
Driver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the trajectory
variations of the vehicle compared to
the lane markings.
The system includes a driving time
alert combined with driver drowsiness detection.
Driving and operating1919Warning
The system cannot replace the
need for vigilance on the part of
the driver. Taking a break is
recommended as soon as feeling tired or at least every two hours.
Do not take the steering wheel
when feeling tired.
Activation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 104.
The state of the system stays in
memory when the ignition is switched
off.
Driving time alert The driver gets notified by a pop-up
reminder symbol € in the Driver
Information Centre simultaneously with an acoustic alert if the driver has
not taken a break after 2 hours of
driving at a speed above 40 mph. The alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.
The counting of driving time alert is
reset when the ignition has been
switched off for a few minutes.
Driver drowsiness detection
The system monitors the driver's level
of vigilance. A camera at the top of the windscreen detects variations in
trajectory compared to the lane
markings. This system is particularly
suited to fast roads (speed higher
than 40 mph).
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent of the driver's level of vigilance.The driver drowsiness detection is
reinitialised when the ignition has
been switched off for a few minutes or the speed remains below 40 mph for
a few minutes.
System limitations In the following situations, the system
may not operate properly or even not operate at all:
● poor visibility caused by inadequate lighting of the
roadway, falling snow, heavy
rain, dense fog etc.
● dazzle caused by headlamps of an oncoming vehicles, low sun,
reflections on damp roads,
leaving a tunnel, alternating
shade and light etc.
● windscreen area in front of the camera covered by dirt, snow,
stickers etc.
● no lane markings detected or multiple lane markings due to
roadworks
● close vehicles ahead
● winding roads or narrow roads

The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
