Rear Pre-Crash Safety system

Rear radar sensor
The rear radar sensor detects
objects approaching from
behind and determines whether
a rear-end collision is imminent
based on the position, speed
and heading of the object
before it happens.
: If equipped
The rear pre-crash safety system will operate to mitigate whiplash
when the rear radar sensor detects an unavoidable rear-end collision
due to a vehicle approaching from the rear.
 Whiplash mitigation (pre-crash intelligent head restraint)
When the system determines that a risk of a rear-end collision is
very high, the sensor in the front head restraint detects the position
of the occupant's head and the head restraint moves to an appropri-
ate position before a rear-end collision in order to mitigate whiplash
when a rear-end collision occurs.
