Differences between Pilot Assist* and Lane Keeping Aid
Pilot Assist is a comfort function that can help keep the vehicle in its own lane and maintain the distance to the vehicle in front of you. Lane Keeping Aid (LKA) is a function that similarly helps in certain situations to reduce the risk of the vehicle unintentionally veering out of its lane.
Pilot Assist
Pilot Assist can help you to steer your vehicle between the lane markings, as well as maintain a preset speed and distance to the vehicle ahead. The function can also use the lane’s side marker lines to help the driver maintain a favorable position in the lane.
- Can help to keep the vehicle within its lane by assisting steering in some cases.
- Can help to maintain a preset speed or the distance to the vehicle ahead by means of acceleration and braking operations.

Lane Keeping Aid can provide steering assistance and/or a warning to the driver when the vehicle is about to leave its lane unintentionally. The function is active between 65-200 km/h (40-125 mph) on roads with clearly visible side markings.
- Lane Keeping Aid can provide the driver with steering assistance, steering the vehicle back into its lane and/or providing warnings using acoustic signals or steering wheel vibration.
An extinguished symbol in the instrument panel means that the function is on but that the conditions for LKA have not been met.
White symbol in the instrument panel means that the conditions for LKA have been met and that the function is available.
A colored symbol in the instrument panel means that LKA provides steering assistance back into the lane and/or gives a warning with sound or vibration in the steering wheel.
Lane Keeping Aid
Lane Keeping Aid (LKA) 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.
A camera monitors the road/traffic lane’s marker lines.
Lane Keeping Aid steers the vehicle back into its lane.
Lane Keeping Aid alerts the driver using vibrations in the steering wheel.
Depending on the settings used, Lane Keeping Aid functions in different ways:
- Steering assistance activated: 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 activated: If the vehicle is about to move over a lane marker line, the driver will be alerted by vibrations in the steering wheel.
You can also have steering assistance and alerts activated 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 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.
Lane Keeping Aid does not intervene in sharp inside curves.
In certain cases, such as when a turn signal is used or if the vehicle is allowed to straighten an inside curve, Lane Keeping Aid will not provide steering assistance or alerts.
If the driver’s hands are not on the steering wheel, an audible signal will be given and a message will instruct the driver to actively steer the vehicle:
- Standby until steering applied Lane Keeping Aid
If the driver does not follow the recommendations and begin steering the vehicle, a warning signal will sound until the driver begins steering the vehicle again.
