Lane keep assist is a driving aid only. Responsibility remains the driver's to drive with due care and attention. Drive in a manner which is safe for the vehicle, its occupants, and other road users. The driver should still observe all road markings.


Low tire pressure and/or wheel alignment issues can affect lane keep assist. Both of these conditions may apply an effect where constant steering adjustment is required.

Lane keep assist is an enhancement of the lane departure warning system.

Lane keep assist aids the driver to keep the vehicle in the current highway lane, e.g., while driving on a multi-lane road. When the vehicle becomes too close to lane markings on either side, without the turn signals being used, the driver is made aware of it.

A rotational force is automatically applied to the steering wheel. The rotational force can be felt by the driver and it indicates that a steering correction should be made. The rotational force can be overridden to make a lane change without use of the turn signals.

When an override is made, and a lane change is taken without use of the turn signals, lane departure warning alerts are triggered. See LANE DEPARTURE WARNING (GREEN).

When lane departure warning is switched on, lane keep assist can be selected via Driver Assistance in the instrument panel menu. See INSTRUMENT PANEL MENU.

When the ignition is switched off and on again, the last choice of lane departure warning or lane keep assist is reinstated.

Lane keep assist is disabled when a fault is detected. A message is displayed in the message center. When the fault does not clear after the ignition is switched off and on again, consult a retailer/authorized repairer.
