Mazda’s Lane-Keep Assist System (LAS) promotes safer driving by providing appropriate steering assistance. The system allows drivers to choose between Lane-Trace, which provides steering assistance early in order to help keep the vehicle centered in the lane and Lane Departure Avoidance, which only comes into play if the vehicle begins to leave its lane. LAS uses a windshield-mounted camera to recognize lane-markings on the road and activates at speeds above 60 km/h.

Helping to avoid unintentional lane departures

When Lane Departure Avoidance is selected, the system works to prevent unintentional lane departures due to driver inattention. If the system predicts that the vehicle is about to stray from its lane, it provides steering assistance to return the car toward the center of the lane.

Line Trace

Lane Trace

When Lane Trace is selected the system reduces the burden of driving by providing continuous steering assistance to help keep the vehicle centered in its lane. On bends the systems help the driver to drive more safely by guiding them toward a steering angle that matches the curvature of the road. Lane Trace is achieved simply by having LAS provide steering assistance from an earlier stage than with Lane Departure Avoidance.

*The system maybe affected by a variety of factors including weather conditions (rain, snow, fog, etc.), and road conditions (tight curves, undulations, unclear lines on the road surface, etc.)
* LAS is designed to alleviate the burden of driving and reduce damage resulting from accidents and is predicated on the driver operating the vehicle in a safe manner. It is important to be aware of the limitations of the system and to drive safely at all times..
* The system is set to avoid unnecessary alarms if the system detects the vehicle behavior is intentional judging from the operation of the accelerator or turn signal.
* Please check the owner’s manual or consult with sales staff for additional important system details, limitations and warnings.
