GWARNING
The function of systems or components can
be affected by conversions or modifications
to the vehicle. They might not function prop-
erly anymore and/or jeopardize the opera-
tional safety of the vehicle. There is an
increased risk of an accident and injury.
Conversions or modifications should always
be carried out at qualified specialist work-
shop.
If you intend to make modifications to your vehi-
cle, we strongly recommend that you contact
the distributor named on the inside of the front
cover. There you will receive all the necessary
information and a charge may be levied.
You alone accept the responsibility if body man-
ufacturers or dealers make modifications that
affect the final certification of the engine, the
vehicle or the equipment. This also applies to
the identification and documentation of modifi-
cations to the affected vehicle components.
You are responsible for certification and confir-
mation that:
Rall the applicable standards and regulations
that are affected by the vehicle modification
are met
Rthe modified vehicle fulfills the vehicle safety standards and emissions laws and regula-
tions
Rthe modifications or installation of accesso-
ries does not affect the safety of the vehicle
We are not responsible for the final certification,
product liability or warranty claims which result
from the modifications. This applies to:
Rthe modified components, assemblies or sys-
tems
Rany resulting noncompliance with any of the
emissions laws and regulations or the motor
vehicle safety standards
Rany consequences arising from the changes
that make the vehicle less safe or even render it defective
We do not assume responsibility as the final-
stage manufacturer or for the consequential
product liability.
Notes on the radiator
Even seemingly small changes to the vehicle,
such as attaching a radiator trim for winter driv-
ing, is not permitted. Do not cover up the radi-
ator. Do not use thermal mats, insect protection
covers or anything similar.
Otherwise, the values of the diagnostic system
may be affected. Some of these values are
legally prescribed and must always be correct.

HEnvironmental note
We supply reconditioned assemblies and
parts which are of the same quality as new
parts. The same New Vehicle Limited War-
ranty applies as for new parts.
The operating safety of the vehicle could be
jeopardized if you use parts, tires and wheels as
well as accessories relevant to safety which
have not been approved by Mercedes-Benz. This could lead to malfunctions in safety-relevant
systems, e.g. the brake system. Only use genu-
ine Mercedes-Benz parts or parts of equal qual-
ity. Only use tires, wheels and accessories that
have been specifically approved for your vehi-
cle.
