driving style, among other factors. Therefore,
Mercedes-Benz recommends regular checks
for wear and proper inflation and, if applicable
to your vehicle’s tire configuration, tire
rotation.
Tire rotations can be performed on vehicles
with the same front and rear tire dimensions.
If your vehicle is equipped with the same tire
dimensions, tires can be rotated by observing
a front-to-rear rotation pattern that will
maintain the intended rotation (spinning)
direction of the tire (on unidirectional tires, an
arrow on the sidewall indicates the intended
rotation or spinning direction of the tire). In
some cases, such as when your vehicle is
configured with staggered sizes (different tire
sizes, front vs. rear), tire rotations are not
possible.
If your vehicle’s tire configuration allows for
tire rotation, tire rotation should be
performed in accordance with the
recommended intervals, or sooner at first
signs of irregular (uneven) tread wear. Tire
rotation recommendations will likely
necessitate a tire rotation at least once in
between maintenance services and at every
maintenance service based on Mercedes-
Benz maintenance intervals.
For your convenience, this Maintenance
Booklet contains a tire rotation confirmation
page on which you can record the date and
mileage when tire rotations were performed
(

Severe operating conditions
The maintenance intervals have been
determined so that the vehicle, under normal
operating conditions, should operate
properly between maintenance services.
Severe operating conditions may call for
correspondingly sooner replacement of the
following items:
R
INTERIOR FILTERS
(e.g. dust filter, recirculating air filter,
activated charcoal filter or combination
filter) are replaced as called for by the
Maintenance System. Under severe dust
conditions, or with the Climate Control
frequently operating in the air recirculation
mode, the filters should be replaced
correspondingly sooner and changed more
frequently than as called for by the
Maintenance System.
R
SPARK PLUGS
Spark plugs should be replaced according
to the specified maintenance interval.
Severe operating conditions (frequent
starting and stopping, excessive idling,
sustained fast highway driving) may call for
spark plugs to be replaced correspondingly
sooner.
R
COOLANT
Have the coolant (water/anticorrosion/
antifreeze mixture) replaced at the
specified maintenance interval. In vehicles
with engine 275 and G-Class with
engine 113, the coolant should be checked
for proper concentration before the start of
each winter season (or once a year in hot
regions).
Replacement of coolant may be required
more frequently if coolant is not maintained
according to instructions and/or other
than approved anticorrosion/antifreeze
products for your vehicle are being used.
For instructions on coolant, see “Coolants”
in your vehicle Operator’s Manual. For a
listing of approved anticorrosion/
antifreeze products for your vehicle,
contact your authorized Mercedes-Benz
Center.
Wear items
While the Maintenance System calls for
inspection of certain wear items, the system
does not make any judgment on the condition
