Sedan
Adjust front seat belts so that the
shoulder portion of the belt is
located as close as possible to the
middle of the shoulder (it should
not touch the neck). For this
purpose, raise or lower the belt
outlet (3 positions). To lower the
belt outlet, press button (4).
The belt must be pulled snug and
checked for snugness immedia­
tely after engaging it and during
driving. If necessary, tighten the
lap portion to a snug fit by pulling
shoulder portion up.
Coupe
When the respective door is
closed and the key is in steering
lock position 2, the seat belt
extender brings the belt forward
within easy reach of the occupant.
The seat belt extender returns to
its rest position when the seat belt
is buckled or when resistance to
its extension is encountered (e.g.,
accidental occupant contact).
If the seat belt is not buckled
within 30 seconds, the seat belt
extender will return to its rest
position.
This is also the case if the key is
turned to steering lock position 1
or 0 or if the door is opened.
Emergency operation:
If the electrical system fails, the
extender arm and belt can be
manually pushed back into their
rest position.
The belt must be pulled snug and
checked for snugness imme­
diately after engaging it and
during driving. If necessary,
tighten the lap portion to a snug fit
by pulling shoulder portion up.
The swivel fitting (mounted on the
lower anchoring point to facilitate
entering the vehicle) must point
forward when fastening the seat
belt.
The pivot plate must face to the
rear with the seat belt extender in
the retracted position.
