Lane Keeping Aid

Lane Keeping Aid (LKA1) is designed to actively steer the vehicle on freeways, highways and other major roads to help the driver reduce the risk of the vehicle unintentionally veering out of the lane.

Lake Keeping Aid steers the vehicle back into the lane and/or alerts the driver using vibrations in the steering wheel.

Lane Keeping Aid is active at speeds between 65–200 km/h (40–125 mph) on roads with clearly visible traffic lane marker lines.

On narrow roads, the function may be unavailable and go into standby mode. The function will become available again when the road becomes sufficiently wide.

Depending on the settings used, Lane Keeping Aid functions in different ways:
  • Assist enabled: When the vehicle approaches a lane marker line, the function will actively steer the vehicle back into the lane using light pressure on the steering wheel.
  • Warning enabled: If the vehicle is about to move over a lane marker line, the driver will be alerted by vibrations in the steering wheel.

There is also an option for activating steering assistance and alerts at the same time.


When the direction indicators/turn signals are activated, the Lane Keeping Aid does not provide any warning or intervene with steering.


  • The function is supplementary driver support intended to facilitate driving and help make it safer – it cannot handle all situations in all traffic, weather and road conditions.
  • The driver is advised to read all sections in the Owner's Manual about this function to learn of its limitations, which the driver must be aware of before using the function.
  • Driver support functions are not a substitute for the driver's attention and judgment. The driver is always responsible for ensuring the vehicle is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.

In certain cases, such as when a turn signal is used or when "straightening out" an inside curve, Lane Keeping Aid will not provide steering assistance or alerts.

Hands on the steering wheel

Steering assistance with Lane Keeping Aid only functions if the driver's hands are on the steering wheel, which the system continuously monitors.

  • Lane Keeping AidApply steering

If the driver does not begin to steer the vehicle, the function will go into standby mode and this message will be displayed:

  • Lane Keeping AidStandby until steering applied

The function will then be unavailable until the driver begins actively steering the vehicle again.
