While driving, pay attention tovibrations, noises
and unusual driving characteristics, e.g. pulling to
one side. This may indicate damage tothe wheels
or tyres. If you suspect that a tyre is defecti ve,
re duce your speed. Stop theve hicle as soon as
possible tocheck if wheels and tyres ha vebeen
damaged or are no longer functioning proper ly.
Hidden tyre dama gecould also be causing the
unusual driving characteristics. If no signs of dam-
age can be de tected, ha vethe tyres and wheels

WARNING
ARNING Risk of injury due todamaged
tyres
Damaged tyres can cause tyre pressure loss. #
Check the tyres regular lyfor signs of
damage and replace any damaged tyres
immediatel y. Check
the wheels and tyres of your vehicle for
damage regular ly, i.e. at least everytwo weeks, as
we ll as aTer driving o.- road or on rough roads.
Damaged wheels can lead toa loss of tyre pres-
sure.
Look out forth efo llowing types of damage, for
ex ample:
R cuts in the tyres
R punctures in the tyres
R tears in the tyres
R bulges on tyres
R deformation or se vere cor rosion on wheels &
W WARNING
ARNING Risk of aquaplaning due to
insu1cient tyre tread
Insu1cient tyre tread will result in reduced tyre
gr ip.
The risk of aquaplaning is increased on wet
ro ads, especially when the speed of theve hicle
is not adap tedto suit the conditions. #
Thus, you should regular lych eck the
tread dep thand the condition of the
tread across the entire width of all tyres. Minimum tread dep
thfor:
R Summer ty res: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legall y-prescribed limit forthe
minimum tread dep thisreached. Conduct
thefo llowing checks regular lyon all
wheels, at least once a month or as requ ired, e.g.
before a long journey or when driving o.- road:
R check the tyre pressure (/ page 253)
R check theva lve caps
Va lves must be pr otected from moisture and
dirt with valve caps speci/cally appro vedby
Mercedes-Benz foryo ur vehicle.
R visually inspect the tread dep thand the tyre

WARNING
ARNING Risk of accident due toincor-
re ct wheel and tyre dimensions
The spare wheel can signi/cant lyimpair the
driving characteristics of theve hicle.
To prev ent hazardous situations: #
Adapt your driving style accordingly and
drive carefull y. #
Never /t more than one spare wheel that
di.ers in size tothe wheel being
re placed. #
Only use the spare wheel brie0y. #
Have a spare wheel of a di.erent size
re placed at the nearest quali/ed special-
ist workshop. It is essential that the new
wheel and tyre ha vethe cor rect dimen-
sions and that the cor rect tyre type is
obser ved. R
When using a spare wheel (di.erent from the
wheel tobe replaced), you must not exceed a
to p speed of 80 km/h.
R The tyre pressure of the spare wheel must be
ch ecked before starting a journey and, if nec-
essar y,adjusted (/ page 254).
R Have the spare wheel replaced bya quali/ed
specialist workshop. The
following should be checkedre gular ly, particu-
lar lyprior tolong journe ys:
R the secure positioning of the spare wheel
R the tyre pressure of the spare wheel (adjust
th e tyre pressure if necessary) (/ page 254)
R thefa stenings of the spare wheel holder
The spare wheel is located in a spare wheel holder
under there ar of theve hicle.
Re place the tyres aTer six years at the latest,
re ga rdless of wear. This also applies tothe spare
wheel.
% Ifyo u ha ve/tted a spare wheel, the tyre pres-
