152Driving and operating
The system recognises the traffic
signs above and displays them in the
Driver Information Centre.
9 Warning
The actual traffic sign always
takes priority over the traffic sign displayed in the Driver Information Centre.
If the vehicle enters a road of whichthe entry is prohibited, the no entry
traffic symbol and a warning message are displayed in the Driver
Information Centre. If the system
detects one of the other traffic signs,
the respective traffic sign is displayed
in the Driver Information Centre.

Lane keep assist
Lane keep assist supports the driver
to avoid unintended leaving of the
lane. The front camera observes road
edges, as well as the lane markings
between which the vehicle is driving.
If the vehicle approaches a road edge or a lane marking, the steering wheel
is gently turned to position so that the
vehicle turns back into the lane. The
driver will then notice a turning
movement of the steering wheel. Turn steering wheel in same direction, if
the system does not steer sufficiently.
Turn steering wheel gently into
opposite direction, if lane change is
intended.
When the system steers to correct the trajectory of the vehicle, L flashes
yellow in the instrument cluster.
Unintended lane departure is not
assumed by the system when the turn lights are operated and during few
seconds after turn lights have been
switched off.Note
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.
Following preconditions have to be
fulfilled:
● vehicle speed must be between 65 km/h and 180 km/h
● the driver must hold the steering wheel
● the turn lights are not activated
● the electronic stability control is activated and not in operation
● the vehicle is not connected to a trailer or an electric bicycle carrier
● normal driving behaviour (system
detects dynamic driving style, i.e. pressure on the brake or
accelerator pedal)
● roads with good lane markings ● no spare wheel is used
● the driver is not taking the hands off the steering wheel for a longer
time period
● the vehicle is not driven in a tight
corner
Driving and operating153Activation
If the system is activated, the LED in
the button j is not illuminated. To
activate the system when the system
is deactivated, press j.
The system is operational at vehicle
speeds between 65 km/h and
180 km/h and if lane markings are
detectable. The driver must hold the
steering wheel. The electronic
stability control system must be
activated.
The control indicator L flashes
yellow during trajectory correction.
If the driver wishes to maintain the
trajectory of the vehicle, he can
interrupt the correction by keeping a
firm grip on the steering wheel, e.g.
during an avoiding manoeuvre. The
correction is interrupted if the turn
lights are operated. If the vehicle is
equipped with active side blind spot detection, the interruption of the lane
correction might be cancelled.
Side blind zone assistant 3 146.
There is no correction triggered when
the turn lights are operated and
during few seconds after turn lights
have been switched off.
If the system detects that the driver is not holding the steering wheel
permanently, it interrupts the
correction. A warning message in the
Driver Information Centre
accompanied by a warning chime
alerts the driver when immediate
driver´s action is required.Deactivation
To deactivate the system, press and
hold j. Deactivation of the system is
confirmed by the illuminated LED in
the button and L illuminates yellow
in the instrument cluster.
Fault
In the event of a fault, L and C
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:
● a dirty or foggy windscreen or if the windscreen is affected by
foreign objects, e.g. stickers
● close vehicles ahead
● banked roads
● winding or hilly roads
● road edges
● sudden lighting changes
