i-ACTIVSENSE*
▼i-ACTIVSENSE
i-ACTIVSENSE is a collective term
covering a series
of advanced safety
and driver support systems which
make use of cameras and sensors. The
systems consist of active safety and
pre-crash safety systems.
These systems are designed to assist
the driver in safer driving by reducing
the load on the driver and helping to
avert collisions or reduce their severity.
However, because each system has its
limitations, always drive carefully and
do not rely solely on the systems.
▼ Active Safety Technology
Active Safety Technology supports safer
driving by helping the driver to
recognize potential hazards and avert
accidents.
