DRIVER SUPPORT
||
NOTE
If the turn signal is used, neither of the driving
lane assistance systems (LDW or LKA) will
provide an alert or steering assistance.
WARNING
This feature is only intended to assist the
driver and does not function in all driving,
weather, traffic or road conditions.
As the driver, you have full responsibility for
operating the vehicle in a safe manner.
Steering assistance (LKA only)
In order for LKA's steering assistance to function,
the driver's hands must be on the steering wheel,
which the system monitors continuously.
If this is not the case, this sym-
bol will illuminate in the instru-
ment panel and
Assistance Apply steering
will appear to alert the driver to
actively steer the vehicle.
If the driver does not take action, an audible sig-
nal will sound and LKA will go into standby mode.
The function will not become available again until
the driver actively steers the vehicle.

Dynamic cornering
The traffic lane assistance systems do not intervene in
sharp curves
In certain cases, such as during active driving or if
the turn signal is used, neither of the traffic lane
systems will react if the vehicle crosses a lane
marker line.
Limitations
Lane
In certain demanding driving situations, the driv-
ing lane assistance functions may not be able to
assist the driver. In these situations, it may be
advisable to turn the function off.
Examples of these situations:
•
road construction
•
poor road surfaces
•
edges or lines other than the lane's marker
lines
•
a very active driving style
•
winter driving conditions
•
bad weather with reduced visibility
The driving lane assistance function use the vehi-
cle's camera, which has general limitations. See
the article "Camera limitations."
