Checking and replacing safety belts
Have the work performed only by your
service center; otherwise, it cannot be ensured
that this safety feature will function properly.◀
Belt carrier
The concept
The belt carrier makes it easier to put on the
safety belt.
General information
After the door is closed and the vehicle key has
been detected in the passenger compartment,
the belt carrier extends automatically and
keeps the safety belt ready to put on, arrow.
After the belt is put on, it goes back into the
idle position.
If the safety belt has not yet been applied, the
belt carrier goes back under the following cir‐
cumstances:
▷ Waiting time approx. five minutes.
▷ Opening the respective door.
▷ After a short trip.
▷ Locking the vehicle.
If the respective door is closed, the belt carrier
is re-activated when the vehicle key has been
detected in the interior.

Pinch protection system
Free range of movement of the belt car‐
rier
Even with pinch protection, make sure that the
range of motion of the belt carrier remains free.
Otherwise, an interruption is not guaranteed
under certain circumstances.◀
If the belt carrier encounters resistance when
extending or retracting, the belt carrier moves
back somewhat in the respective opposite di‐
rection and stops in this position.
To reactivate the belt carrier, open and close
the door or turn the ignition off and on.

is as close as possible to the back of the head.
