311 Operation
Tires and wheels
Tires and wheels
See 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 inflation pressure loss and
damage to the tire beads.
If vehicle is heavily loaded, check tire
inflation pressure and correct as re-
quired.
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 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, 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 possibly an
accident.

325 Operation
Tires and wheels
Press the æ button.
The following message will appear in
the multifunction display field:Tire pres. monitor
reactivated
The tire pressure monitoring system
will now monitor the tire inflation pres-
sure values of all four tires.
The following message will appear in
the multifunction display field:
Tire pressure
displayed only
after driving
a few mins. This display appears until the individual
inflation pressure values are matched
with the tires. The individual values are
then displayed (
page 396).If you wish to cancel activation:
Press the ç button.
If one of the following messages appears in
the multifunction display:
reactivate tire
pressure monitor
after rectifying
pressure
Tire pressure
Please rectify
Check the tire inflation pressures and
correct them if necessary.
Reactivate the tire pressure monitoring
system.
iAfter you have reactivated the tire
pressure monitoring system, the cur-
rent tire inflation pressure values will
only be shown after several minutes of
driving. During this time, the following
message appears in the display:Tire pressure
displayed only
after driving
a few mins. The time before the tire inflation pres-
sures are shown depends on whether
or not
you have mounted new tires
the old tires are still on the vehicle
If you have mounted new tires, it will
take slightly longer before the tire infla-
tion pressures are shown in the display.

339 Operation
Tires and wheels
TIN (T
ire I
dentification N
umber)
Unique identifier which facilitates efforts
by tire manufacturers to notify purchasers
in recall situations or other safety matters
concerning tires and gives purchases the
means to easily identify such tires. The TIN
is comprised of “Manufacturer's identifica-
tion mark”, “Tire size”, “Tire type code”
and “Date of manufacture”.
Tire load rating
Numerical code associated with the
maximum load a tire can support.
Tire ply composition and material used
This indicates the number of plies or the
number of layers of rubber-coated fabric in
the tire tread and sidewall. Tire manufac-
turers also must indicate the ply materials
in the tire and sidewall, which include
steel, nylon, polyester, and others.Tire speed rating
Part of tire designation; indicates the
speed range for which a tire is approved.
Traction
Force exerted by the vehicle on the road
via the tires. The amount of grip provided.
Tread
The portion of a tire that comes into
contact with the road.
Treadwear indicators
Narrow bands, sometimes called
“wear bars” that show across the tread of
a tire when only
1/6in (1.6 mm) of tread
remains.Uniform Tire Quality Grading Standards
A tire information system that provides
consumers with ratings for a tire's traction,
temperature and treadwear. Ratings are
determined by tire manufacturers using
government testing procedures. The
ratings are molded into the sidewall of the
tire.
Vehicle capacity weight
Rated cargo and luggage load plus
68 kilograms (150 lbs) times the vehicle's
designated seating capacity.
Vehicle maximum load on the tire
Load on an individual tire that is
determined by distributing to each axle its
share of the maximum loaded vehicle
weight and dividing it by two.

75The indicator lamp illuminates and remains
illuminated with the weight of a typical adult
or someone larger than a small individual on
the front passenger seat.
The system is malfunctioning.
Have the system checked as soon as
possible by an authorized
Mercedes-Benz Center.
Also note any messages in the
multifunction display and follow cor-
rective steps (
page 374).
Warning!
G
If the
75
indicator lamp illumi-
nates and remains illuminated with the
weight of a typical adult or someone larger
than a small individual on the front passen-
ger seat, do not have any passenger use the
front passenger seat until the system has
been repaired.

See Operator’s Manual
Air bag is activated while
driving even though a child,
small individual, or object
below the system's weight
threshold is on the front
passenger seat, or the
front passenger seat is
empty. Objects on the seat
or forces acting on the seat
may make the system
sense supplemental
weight.
Stop the vehicle in a safe location as soon as possible
and check the following:
Make sure that there is nothing between seat cush-
ion and child seat and check installation of the child
seat.
Make sure that no objects applying supplemental
weight onto the seat are present.
Make sure that no objects which apply forces to the
seat are present (e.g. objects such as books, brief-
cases etc. lodged behind or around the seat, head
restraints pushing against roof etc.). The system
may recognize such forces as supplemental weight
and sense that an occupant on the front passenger
seat is of a heavier weight than actually present.

See Operator’s Manual
Air bag is deactivated while
driving even though an
adult or someone larger
than a small individual is
occupying the front pas-
senger seat. Forces acting
on the seat may make the
system sense a decrease
in weight.
Stop the vehicle in a safe location as soon as possible
and check the following:
Do not lean on armrests or lift yourself up using han-
dle over the door.
Adjust the seat in a height position (
page 38).
Make sure that no objects which apply forces to the
seat are present (e.g. objects such as books, brief-
cases etc. lodged underneath, behind or around the
seat). Such forces may cause the system to sense
that an occupant of a lesser weight than actually
present is on the front passenger seat.
Re-position yourself.
Sit properly belted in a nearly upright position with
your back against the seat backrest.
If performing any of the above corrective steps is
successful, the message
Front passenger airbag

will appear in the multifunction display,
confirming the situation has been remedied.
