Lane Keeping Aid steers the car back into its lane and/or alerts the driver with vibrations in the steering wheel.
Lane Keeping Aid is active within the speed range 65–200 km/h (40–125 mph) on roads with clearly visible side lines.
On narrow roads the function may be unavailable, in which case it goes into standby mode. The function becomes available again when the road is wide enough.
Depending on settings, lane assistance acts in accordance with the following:
- Assist activated: When the car is approaching a lane line, the function will actively steer the car back into its lane by applying a slight torque to the steering wheel.
- Warning activated: If the car is about to cross a lane line, the driver is warned by means of vibrations in the steering wheel.
- There is also an option where both steering assistance and warning are activated simultaneously.
Note
When a direction indicator/flasher is switched on, there are no steering corrections or alerts from lane assistance.
Warning
- The function is supplementary driver support intended to facilitate driving and 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 that relate to this function to learn about factors such as its limitations and what the driver should be aware of before using the system.
- Driver support functions are not a substitute for the driver’s attention and judgement. The driver is always responsible for ensuring the car 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 assistance does not intervene
In some situations, lane assistance allows lane lines to be crossed without intervening with either steering assistance or a warning – e.g. when using the direction indicators or if the car is allowed to cut the corners in bends.
Hands on the steering wheel
For steering assistance with lane assistance to work, the driver must have his/her hands on the steering wheel, which the system will continue to monitor.
If the driver does not keep his/her hands on the steering wheel, a warning signal is heard and a message encourages the driver to steer the car actively:
- Lane Keeping Aid Apply steering
If the driver does not follow the prompt to start steering, the function is set in standby mode, and this message is shown:
- Lane Keeping Aid Standby until steering applied
The function will then be unavailable until the driver starts to steer the car again.
Activating and deactivating lane assistance
The Lane Keeping Aid (LKA) function (LKA(Lane Keeping Aid)) is optional – the driver can choose to activate or deactivate this function.
Activate or deactivate the function using this button in the centre display’s function view.
- Illuminated button – the function is activated.
- Extinguished button – the function is deactivated.
Difference between Pilot Assist and lane assistance
Pilot Assist is a comfort function that can help you to keep your car within its own lane and maintain a safe distance from vehicles in front of you. Lane assistance(Lane Keeping Aid) is a function which, in a similar way, can help you in some situations to reduce the risk of your car accidentally leaving its own lane.
Pilot Assist
Pilot Assist can help you to steer your car between the lane’s markings, as well as maintaining a preset speed and time interval to the vehicle ahead. The function can also help to maintain an advantageous position in the lane using the lane’s lane lines.
What does Pilot Assist do?
- Can help to keep the car 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.
How do I know when Pilot Assist is operational?
Symbols in the driver’s display in the car indicate when this function is operational.
When the steering wheel in the middle is extinguished, Pilot Assist is running but steering assistance is not active.
When the steering wheel is illuminated, Pilot Assist is running and steering assistance is active.
Lane assistance
Lane assistance can provide steering assistance and/or give you an alert when the vehicle is about to leave its own lane unintentionally. This function is active in the speed range 65-180 km/h (40-112 mph) on roads with clearly visible lane lines.
What does lane assistance do?
- Lane assistance can provide the driver with steering assistance, steering the car back into its lane and/or providing warnings using acoustic signals or steering wheel vibration.
How do I know when lane assistance is operational?
Symbols in the driver’s display in the car show the status of the function.
An extinguished symbol in the driver display means that the function is running but the conditions for LKA have not been met.
A white symbol in the driver’s display means that the conditions for LKA have been met and that the function is available.
An orange symbol in the driver’s display means that LKA is providing steering assistance back in to the lane and/or will provide warnings using acoustic signals or steering wheel vibration.
Warning
The driver always bears responsibility for ensuring that the car is driven safely. Before using this function, the driver is recommended to read all sections on the function in the owner’s manual.

Display mode for lane assistance
Lane assistance (LKA(Lane Keeping Aid)) is visualised by symbols in the driver display depending on the situation.
Here are some examples of symbols and the situations in which they are shown:
Available
Lane assistance is scanning one or both lane lines.
The Lane assistance cannot detect the lane lines, the speed is too low or the road is too narrow.
Indication of steering assistance/warning
Lane assistance indicates that the system is giving a warning and/or attempting to steer the car back into the lane.
Limitations of Lane assistance
In certain demanding conditions, lane assistance (LKA(Lane Keeping Aid)) may have difficulty helping the driver correctly. In such cases it is recommended to switch off this function.
Examples of such conditions are:
- road works
- winter road conditions
- poor road surface
- a very “sporty” driving style
- poor weather with reduced visibility
- roads with unclear or non-existent side markings
- sharp edges or lines other than the lane’s side markings
- as the steering servo for speed-dependent steering wheel resistance is working at reduced power – e.g. when cooling due to overheating.
The function is unable to detect barriers, rails or similar obstacles at the side of the carriageway.
Note
This function uses the car’s camera and radar units, which have certain general limitations.
