System limitations
The system performance may be
affected by:
● covered camera by snow, ice,
slush, mud, dirt, or affected by
windscreen damage or foreign
items, e.g. stickers
● close vehicles ahead
● banked roads
● winding or hilly roads
● poor lighting conditions
● sudden lighting changes
● shining sun directly into the
camera lens
● adverse environmental
conditions, e.g. heavy rain, fog,
or snow
● vehicle modifications, e.g. tyres
● roads with poor lane markings
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 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 Driver Information
Centre. Lane keep assist does not
continuously steer the vehicle.
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.
If the system detects that the steering
wheel is not held permanently, it
interrupts the correction after a short
time.
When hands-off driving is detected
during a correction a warning
message appears in the Driver
Information Centre, accompanied by
