Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Rear Traffic Alert function is only an assist and is not a replacement for
careful driving. Driver must be careful when backing up, even when using Rear
Traffic Alert function. The driver’s own visual confirmation of behind you and
your vehicle is necessary and be sure there are no pedestrians, other vehicles
etc. before backing up. Failure to do so could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore the
driver’s own visual confirmation of safety is necessary.
