■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 driv-
ing. Driver must be careful when backing up, even when using Rear Traffic Alert func-
tion. 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.
