Lane Change Alert Description and Operation: Notes

WARNING: This page is about a different car, the 2018 Buick Envision. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

When the vehicle is new, or the system has been programmed, there may be intermittent false alerts for up to 644 km (400 miles). The system is in an auto learn mode at this time.

Lane Change Alert (LCA) can be disabled in vehicle personalized settings, this will also disable the Side Blind Zone Alert (SBZA) system. When disabled, the bulb check of the mirror indicators will also be disabled. A driver information center message will be displayed at start up when the LCA system is disabled. This feature must be enabled prior to trying to diagnose the system.

This is a feature of the Side Blind Zone system, for more information, refer to Side Blind Zone Alert Description and Operation . Lane Change Alert system is a lane-changing aid that assists drivers with avoiding lane change crashes that occur with moving vehicles in the side blind zone (similar to blind spot) areas or with vehicles rapidly approaching these areas from behind. The Lane Change Alert warning display will light up in the corresponding outside side mirror and will flash if the turn signal is on.

The Lane Change Alert sensor covers a zone of approximately one lane over from both sides of the vehicle, or 3.5 m (11 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2 m (6 ft) off the ground. The Side Blind Zone Alert (SBZA) warning area starts at approximately the middle of the vehicle and goes back 5 m (16 ft). Drivers are also warned of vehicles rapidly approaching from up to 25 m (82 ft) behind the vehicle.
