Unfastening of Seat Belts
Push the release button (3) in the belt
buckle (2).
Allow the retractor to completely
rewind the seat belt by guiding the

unwinding during sudden vehicle stops
or when quickly pulling on the belt.
The locking function of the reel may be
checked by quickly pulling out the belt.
Lap Belt for Center Seating Position
of the Rear Seat
Pull belt with latch plate (1) over lap so
that the belt is positioned as low as
possible on your hips and not across the
abdomen. Push latch plate (1) into
buckle (2) until it clicks. Do not twist
the belt. A twisted seat belt may cause
injury.
To tighten the belt:
With the latch plate engaged, pull
the loose end of the belt.
To lengthen the belt: With the belt
unfastened, turn the latch plate so that
it is a little more than 90°
perpendicular to the belt, then extend
the belt. Fasten the belt and tighten as
stated above.
To unfasten the belt, push red button
(3) in the buckle.
If the center seat is not occupied, the
belt buckle and rolled-up seat belt can
be stored in the space provided in the
seat bench.
