RNING
Driving safety may be impaired if non-
approved parts ,tyres and wheels or safety-
relevant accessories are used.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. This
could cause you to lose control of your vehicle
and cause an accident.
For this reason, Mercedes-Benz recommends
that you use genuine Mercedes-Benz parts or
parts of equal quality. Only use tyres, wheels
and accessories that have been specifically
approved for your vehicle. H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.

as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:
R doors
R doo rpillars

Mercedes-Benz tests genuine parts and con-
version parts and accessories that have been
