footwell or behind the seats when moving
the seat back. There is a risk that the seats
and/or the objects could be damaged.

PRE-SAFE takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations. Although your vehicle is equipped
with a PRE-SAFE

prevailing road and weather conditions and
maintain a safe distance from the vehicle in
