262 OperationTires and wheels
Tires and wheelsSee an authorized Mercedes-Benz Center 
for information on tested and recommend-
ed rims and tires for summer and winter 
operation. They can also offer advice con-
cerning tire service and purchase.
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous 
damage cannot always be recognized on 
retreads. Mercedes-Benz can therefore 
not assure the operating safety of the vehi-
cle when such tires are used. 
See an authorized Mercedes-Benz Center 
for information on tested and recommend-
ed rims and tires for summer and winter 
operation. 
Important guidelines
Only use sets of tires and rims of the 
same type and make.
Tires must be of the correct size for the 
rim. 
Break in new tires for approximately 
60 miles (100 km) at moderate 
speeds. 
Regularly check the tires and rims for 
damage. Dented or bent rims can 
cause tire pressure loss or damage the 
tire beads.
If vehicle is heavily loaded, check tire 
pressure and correct as required.
Do not allow your tires to wear down 
too far. Adhesion properties on wet 
roads are sharply reduced at tread 
depths under 
1/8in (3 mm).
When replacing individual tires, you 
should mount new tires on the front 
wheels first (on vehicles with 
same-sized wheels all around). 
Warning!
G
Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the 
original part. See an authorized 
Mercedes-Benz Center for further informa-
tion. If incorrectly sized rims and tires are 
mounted:
The wheel brakes or suspension compo-
nents can be damaged.
The correct operating clearance of the 
wheels and the tires is no longer guaran-
teed.
Warning!
G
Worn, old tires can cause accidents. If the 
tire tread is badly worn, or if the tires have 
sustained damage, replace them.
When replacing rims, only use genuine 
Mercedes-Benz wheel bolts specified for the 
particular rim type. Failure to do so can re-
sult in the bolts loosening and may lead to 
an accident.

267 Operation
Tires and wheels
Rotating wheels
On vehicles with the same wheel size all 
around, wheels can be rotated every 3 000 
to 6 000 miles (5 000 to 10 000 km), or 
sooner if necessary, according to the de-
gree of tire wear. The same direction of tire 
rotation must be retained. 
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible 
(shoulder wear on front wheels and tread 
center wear on rear wheels).Thoroughly clean the inner side of the 
wheels after each rotation. Check and en-
sure proper tire inflation pressure, activat-
ing the tire inflation pressure monitor if 
necessary. For information on wheel change, see the 
“Practical hints” section (
page 323) and 
(
page 339).
Warning!
G
Rotate front and rear wheels only if they are 
of the same size. 
!If your vehicle is equipped with a tire in-
flation pressure monitor*, there are 
electronic components built into the 
wheel.
Do not use mounting tools in the area 
of the valve as they could damage the 
electronic components. 
To prevent damage or incorrect instal-
lation, have the tires changed at an au-
thorized Mercedes-Benz Center.
Warning!
G
Have the tightening torque checked after 
changing a wheel. Wheels could become 
loose if not tightened with a torque of 
96 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel 
bolts specified for your vehicle's rims.

280 OperationVehicle careUpholstery
Using aftermarket seat covers or wearing 
clothing that have the tendency to give off 
coloring (e.g. when wet, etc.) may cause 
the upholstery to become permanently dis-
colored. By lining the seats with a proper 
intermediate cover, contact-discoloration 
will be prevented.
Leather upholstery
Wipe leather upholstery with a damp cloth 
and dry thoroughly or clean with 
Mercedes-Benz approved Leather Care. 
Exercise particular care when cleaning per-
forated leather as its underside should not 
become wet.Plastic and rubber parts
Do not use oil or wax on these parts.
Wood trims
Dampen cloth using water and use damp 
cloth to clean wood trims in your vehicle. 
Do not use solvents like tar remover or 
wheel cleaner nor polishes or waxes as 
these may be abrasive.

378 Technical dataRims and tires
Rims and tiresOnly use 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
!Moreover, tires and rims not approved 
by Mercedes-Benz may, under load, 
exhibit dimensional variations and dif-
ferent tire deformation characteristics 
that could cause them to come into 
contact with the vehicle body or axle 
parts. This may result in damage to the 
tires or the vehicle.
iFurther information on tires and rims is 
available at any authorized 
Mercedes-Benz Center. A tire inflation 
pressure table is located on the fuel fill-
er flap of the vehicle. The tire pressure 
should be checked regularly and 
should only be adjusted on cold tires. 
Follow tire manufacturer’s mainte-
nance recommendation included with 
vehicle.
