Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have accessories retrofitted at a qualified
specialist workshop.
You could jeopardise the operating safety of
your vehicle if you use parts, tyres and wheels
as well as accessories relevant to safety
which have not been approved by Mercedes. This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tyres, wheels and
accessories that have been specifically
approved for your vehicle.
Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been specifically approved for your vehicle for their
reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Mercedes-Benz therefore accepts no responsibility for the
use of such parts in Mercedes-Benz vehicles, even if they have been officially approved or
independently approved by a testing centre.
In Germany, certain parts are only officially
approved for installation or modification if
they comply with legal requirements. This
also applies to some other countries. All gen-
uine Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts may invalidate the vehicle's general operating
permit.
This is the case:
R if they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted
R if other road users could be endangered
R if the emission or noise levels are adversely
affected
Always specify the vehicle identification num- ber (VIN) when ordering genuine Mercedes-
Benz parts (Y page 468). Owner's Manual
Vehicle equipment
This Owner's Manual describes all models
and all standard and optional equipment
available for your vehicle at the time of pub-
lication of the Owner's Manual. Country-spe-
cific differences are possible. Note that your
vehicle may not be fitted with all features
described. This is also the case for systems
and functions relevant to safety. Therefore,
the equipment on your vehicle may differ from that in the descriptions and illustrations.
The original purchase contract documenta-
tion for your vehicle contains a list of all of the
systems in your vehicle.
Should you have any questions concerning
equipment and operation, please consult a
Mercedes-Benz Service Centre.
The Owner's Manual and Service Booklet are important documents and should kept in the
vehicle. Operating safety

Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE ®

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
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 activating and deactivating
the seat-belt adjustment function can be
found in the Digital Owner's Manual or in the separate COMAND Online or Audio 20 oper-
ating instructions.
Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all vehicle occu-
pants to 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 switches off as soon as the driver and co-driver have fastened their seat
belts.
i For more information on the
7seat
belt warning lamp, see the "Warning and
indicator lamps in the instrument cluster,
seat belt" section (Y page 351).
Rear seat belt status indicator The rear seat belt status indicator is only
available for certain countries.
For approximately 30 seconds, the rear seat
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. 50
