Driving lane assistance
The
Lane Departure Warning (LDW) and Lane
Keeping Aid (LKA) * functions are designed to
help reduce the risk of accidents in situations where the vehicle unintentionally leaves its laneon highways or other major roads.
Driving lane assistance systems: LDW or
LKA
There are two versions of the driving lane assis- tance system:
• LDW (
Lane Departure Warning): provides
an audible signal or vibrations in the steering wheel.
• LKA (
Lane Keeping Aid): actively steers the
vehicle to help keep it in its traffic lane and/or alerts the driver using an audible sig-nal or through vibrations in the steeringwheel.
The driving lane assistance systems are active at speeds from approx. 40 mph (65 km/h) up to thevehicle's permitted top speed on roads withclearly visible traffic lane marker lines. On narrow roads, the systems may not function and will go into standby mode. They will return toactive mode if the road becomes sufficientlywide.
A camera monitors the road/traffic lane's marker lines
Both LDW and LKA provide vibrations in the steering wheel 9
LKA attempts to steer the vehicle back into its lane
Depending on the version and settings used, driving lane assistance functions in differentways:
• If the system is activated (either LDW or LKA): if the driver does not react and thevehicle is moving out of its traffic lane, anaudible signal and/or vibrations in the steer-ing wheel will be provided.
• If the system is activated (LKA only): whenthe vehicle approaches a traffic lane markerline, LKA will provide active steering assis-tance to help steer it back into the lane.

The level of vibrations varies; the longer the vehicle is over a lane marker line, the greater the number of vibrations:

NOTE
If the turn signal is used, neither of the driving lane assistance systems (LDW or LKA) willprovide 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
Lane Keeping
Aid 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 untilthe 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 lanesystems will react if the vehicle crosses a lanemarker line.
LimitationsIn certain demanding driving situations, the driv-ing lane assistance functions may not be able toassist the driver. In these situations, it may beadvisable 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. Seethe article "Camera limitations."

Driving lane assistance symbols and messages
A number of symbols and messages relating to Lane Keeping Aid (LKA) and Lane DepartureWarning (LDW) may appear in the instrumentpanel.
Symbols in the instrument panelThe driving lane assistance systems use a symbol in theinstrument panel in differentsituations.
Several examples of the symbol's appearance will be given here:
Available
When the driving lane assistance systems are available,
the marker lines in the symbol will be white
LDW/LKA are monitoring the driving lane's marker line(s).
Not available
When the driving lane assistance systems are not avail-
able, the marker lines in the symbol will be gray
This is because LDW/LKA cannot monitor (detect) the driving lane's marker line(s) or thevehicle's speed is too low or the road is too nar-row.
Steering/warning indicator
Steering/warning: the side marker lines in the symbol will be colored
LDW/LKA alerts the driver that the vehicle is leaving its lane. LKA attempts to steer the vehicleback into the lane. LKA also indicates if the sys-tem is attempting to steer the vehicle back intoits lane.
