Driving lane assistance systems: LDW or LKA
There are two versions of the driving lane assistance 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 signal or through vibrations in the steering wheel.
The driving lane assistance systems are active at speeds from approx. 40 mph (65 km/h) up to the vehicle's permitted top speed on roads with clearly visible traffic lane marker lines.
On narrow roads, the systems may not function and will go into standby mode. They will return to active mode if the road becomes sufficiently wide.
Depending on the version and settings used, driving lane assistance functions in different ways:
- If the system is activated (either LDW or LKA): if the driver does not react and the vehicle is moving out of its traffic lane, an audible signal and/or vibrations in the steering wheel will be provided.
- If the system is activated (LKA only): when the vehicle approaches a traffic lane marker line, LKA will provide active steering assistance to help steer it back into the lane.
Note
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 symbol will illuminate in the instrument panel and Lane Assistance Apply steering will appear to alert the driver to actively steer the vehicle.
If the driver does not take action, an audible signal 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
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
In certain demanding driving situations, the driving lane assistance functions may not be able to assist the driver. In these situations, it may be advisable to turn the function off.
- 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 vehicle's camera, which has general limitations. See the article "Camera limitations."
