STARTING AND DRIVING
Reverse park assist limitations
Reverse Park Assist system is not a colli-
sion avoiding system. It is solely the
driver's responsibility to park the vehicle
safely.
Reverse Park Assist feature works on ul-
tra sound echo technology, due to which
performance is not guaranteed in follow-
ing scenarios:
 If the object has a sharp edge sur-
face, where surface may divert ech-
oes from sensor reception.
 If object is mesh fence made up of
thin wires, where echoes cannot be
given by the surface.
 Fast moving objects passes in the
sensor field of detection, where ech-
oes are not processed by the system.
 If object is made or covered by foam
or sponge or snow where ultrasonic
sound signals are absorbed.
