Driving lane assistance

The Lane Assistance functions are designed to help reduce the risk of accidents in situations where the vehicle unintentionally leaves its lane on highways or other major roads.

Driving lane assistance system

Lane Keeping Aid (LKA) 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 system is active at speeds between approx. 40-125 mph (65-200 km/h) on roads with clearly visible traffic lane marker lines. Always observe posted speed limits.

On narrow roads, the system may not function and will go into standby mode. It will return to active mode if the road becomes sufficiently wide.

Driving lane assistance provides vibrations in the steering wheel1.
Depending on the settings used, Lane Keeping Aid functions in different ways:
  • Assistance type Steering2 is activated: when the vehicle approaches a traffic lane marker line, LKA will provide active steering assistance to help steer it back into the lane.
  • Assistance type Warning2 is activated: if the vehicle is moving out of its traffic lane, an audible signal and/or vibrations in the steering wheel will be provided.

 Note

If the turn signal is used, Lane Keeping Aid will not provide an alert or steering assistance.

 Warning

Lane Keeping Aid 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

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 the driver's hands are not on the steering wheel, this symbol will illuminate in the instrument panel and the following message will be displayed:

  • Lane Keeping Aid – Apply steering
If the driver does not begin to steer the vehicle, the symbol will illuminate again, an audible signal will sound and the following message will be displayed:
  • Lane Keeping Aid – Standby until steering applied

If the driver still does not begin to steer the vehicle, LKA will go into standby mode. The function will not become available again until the driver actively steers the vehicle

Traffic lane assistance does not react

The traffic lane assistance system does not intervene in sharp curves

In certain cases, such as during active driving or if the turn signal is used, the traffic lane system will not 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.

Examples of such situations:
  • road construction
  • winter driving conditions
  • poor road surfaces
  • a very active driving style
  • bad weather with reduced visibility
  • edges or lines other than the lane's marker lines
  • roads with indistinct or no lane marker lines

The driving lane assistance function use the vehicle's camera, which has general limitations. See the article "Camera limitations."

  1. 1 The level of vibrations varies; the farther the vehicle is over a lane marker line, the greater the number of vibrations:
