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 seat belt tongue is engaged in the belt
buckle and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening 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 Online or Audio 20.
Information on switching the seat-belt adjust-
ment function on and off can be found in the
Digital Owner's Manual or in the separate
COMAND Online or Audio 20 operating
instructions. Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster reminds you that all vehicle
occupants must fasten their seat belts. It may
light up continuously or flash. A warning tone
may also sound.
The 7 seat belt warning lamp goes out and
the warning tone stops as soon as the driver's and the co-driver's seat belts have been fas-
tened.
i For more information on the
7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belt" (Y page 376).
Rear seat belt status indicator The rear seat belt status indicator is only
available for certain countries.

belt status indicator informs you which rear
seat belt is not fastened.
The rear seat belt status indicator appears if:
R you drive off and reach a speed of approx-
imately 10 km/h
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion
R someone gets in or out of the vehicle and
you pull away again
You can also cancel the rear seat belt status
indicator immediately (Y page 335).52

Problems with automatic front-passenger front airbag deactivation
Be sure to observe the notes on "System self-test" (Y
page 59).Problem
Possible causes/consequences and
M
MSolutions The PASSENGER AIR
BAG OFF indicator
lamp lights up and
remains lit, even
though the front-
passenger seat is occu-
pied by an adult or a
person with a build cor-responding to that of an
adult. The classification of the person on the front-passenger seat is
false.
X Make sure the conditions for a correct classification of the per-
son on the front-passenger seat are met (Y page 57).
X If the PASSENGER AIR BAG OFF indicator lamp remains lit, the
front-passenger seat may not be used.
X Have the automatic front-passenger front airbag deactivation
system checked as soon as possible at a Mercedes-Benz Ser-
vice Centre. The PASSENGER AIR
BAG OFF indicator
lamp does not light up
and/or does not stay
on.
The front-passenger
seat is:
R empty
R occupied with a rear-
ward-facing child
restraint system The automatic front-passenger front airbag deactivation system is
malfunctioning.
X Make sure there is nothing between the seat and the child
restraint system.
X Make sure that the entire base of the child restraint system rests
on the seat cushion of the front-passenger seat.
X Make sure that the seat cushion length is fully retracted.
X When installing the child restraint system, make sure that the
seat belt is tight. Do not pull the seat belt tight with the front-
passenger seat adjustment. This could result in the seat belt and the child restraint system being pulled too tightly.
X Check that the child restraint system is installed correctly.
X Make sure that no objects are applying additional weight to the
seat.
X If the PASSENGER AIR BAG OFF indicator lamp remains off and/
or the PASSENGER AIR BAG ON indicator lamp lights up, do not
install a rearward-facing child restraint system on the front-
passenger seat. It is recommended that you fit the child
restraint system to a suitable rear seat.

footwell or behind the seats. There is a risk that the seats and/or the objects could be
damaged when PRE-SAFE ®

event of an accident cannot be ruled out.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle

ted:
R the front seat belts are pre-tensioned.
R if the vehicle skids, the side windows and
the panorama sliding sunroof are closed.
R vehicles with the memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavourable
position.

children unattended in the vehicle.
The seats can still be adjusted when there is
no key in the ignition lock. G
