necessary technical data for your vehicle.
Spare parts serviceAll authorized Mercedes-Benz Centers
maintain a stock of original spare parts re-
quired for maintenance and repair work. In
addition, strategically located parts distri-
bution centers provide quick and reliable
parts service.
More than 300 000 different spare parts
for Mercedes-Benz models are available.
Mercedes-Benz original spare parts are
subjected to stringent quality inspections.
Each part has been specifically developed,
manufactured or selected for and adapted
to Mercedes-Benz vehicles.
Therefore, Mercedes-Benz original spare
parts should be installed.
!The use of non-genuine parts and ac-
cessories not authorized by
Mercedes-Benz could damage the vehi-

311 Technical data
Rims and Tires
Rims and Tires
Use only tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as

poor handling characteristics


increased noise


increased fuel consumption
Same size tires
!Moreover, tires and rims not approved
by Mercedes-Benz may, under load, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle can be the result.
iFurther information on tires and rims is
available at any authorized Mercedes-
Benz Center. A tire inflation pressure
table is located on the fuel filler cap of
the vehicle. The tire pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire man-
ufacturer’s maintenance recommenda-
tion included with vehicle.
