Operation
Tires and wheels
Tires and wheels
See your authorized Mercedes-Benz Cen-
ter for information on tested and recom-
mended rims and tires for summer and
winter operation. They can also offer ad-
vice concerning tire service and purchase
Retread 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 your authorized Mercedes-Benz Cen-
ter for information on tested and recom-
mended rims and tires for summer and
winter operation.
Important guidelines

Use only 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.


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 your 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 are no longer guar-
anteed
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, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can re-
sult in the bolts loosening and possibly an
accident.

238 OperationMaintenance
MaintenanceWe strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Center, in accordance with
the Service Booklet at the times called for
by the FSS (F
lexible S
ervice S
ystem).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times /mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
FSS will notify you when your next service
is due.
Approximately one month before your next
service is due, one of the following mes-
sages will appear in the multifunction dis-
play while you are driving or when you
switch on the ignition (example service A):
SERVICE A - IN xx DAYS
SERVICE A - IN xx MILES (KM)
SERVICE A - DUE NOW
The type of service due is indicated in the
multifunction display field:9
Minor service (A)
´
Major service (B)
Clearing the service indicator
The service indicator is automatically
cleared

after 10 seconds when you switch on
the ignition or when reaching the ser-
vice threshold while driving.


after 30 seconds, once the suggested
service term had passed.
You can also clear it yourself by pressing
the reset knob on the instrument cluster
(
page 22).
Service term exceeded
If you have exceeded the suggested ser-
vice term a signal sounds every time when
you switch on the ignition and you will see
the following message in the multifunction
display:SERVICE A EXCEEDED BY xx DAYS
SERVICE A EXCEEDED BY xx MILES (KM)
iThe interval between services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short distance trips will
lengthen the interval between services.
