Rear seat belt buckle extenders
The seat belt extender is an integral part of
the PRE-SAFE ® convenience function. It is
used on the outer rear seats.
Always ensure that it is possible to move the
belt buckle freely. Always stow objects in the
vehicle correctly.
To assist you in finding the seat belt buckle
and fastening the seat belt:
R the belt buckle moves forwards to a con-
venient position
R
the belt buckle is illuminated
After the seat belt is fastened, the belt buckle
returns to its normal position. The seat belt
then lies tight across the lap and thorax areas.
Incorporation into the PRE-SAFE
® system:
the belt buckle is lowered quickly in certain
hazardous situations. This pre-tensions the
seat belt.
Incorporation into the automatic meas-
ures after the accident: in this situation, the
belt buckle is illuminated and extended after
a rear door is opened.
Releasing seat belts
!
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop.

Seat belt adjustment
The seat-belt adjustment is an integral part of
the PRE-SAFE ® convenience function. This
function adjusts the driver's and front-
passenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
R the belt tongue is engaged in the buckle
and
R the ignition is switched on
The seat-belt adjustment will apply a certain
retraction force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off using COMAND. Information on
switching the belt adjustment function on and
off can be found in the digital operating
instructions or in the separate COMAND
operating instructions.
