other obstacles. If it is necessary to drive over
kerbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
may be damaged.
Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control
of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
Regularly check the wheels and tyres of
R
your vehicle for damage at least every 14
days, as well as after driving off-road or on
rough roads. Damage includes cuts, punc-
tures, cracks and bulges on tyres or severe
corrosion or deformation on wheels, for
example. Damaged wheels can cause a
loss of tyre pressure.
Regularly check the tyre tread depth and
R
the condition of the tread across the whole
Y
width of the tyre (
inspect the inner side of the tyre surface,
turn the steering wheel to full lock.
All wheels must have a valve cap to protect
R
the valve against dirt and moisture. Do not
fit anything onto the valve other than the
standard valve cap or a valve cap approved
by Mercedes-Benz for your vehicle.
Do not fit anything onto the valve, such as
tyre pressure monitoring systems.
You should regularly check the pressure of
R
all your tyres including the spare wheel,
particularly prior to long trips. Adjust the
tyre pressure as necessary (
The service life of tyres depends on various
factors, including the following:

Tyre tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces,
the risk of aquaplaning increases, in particular
where speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres
may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
summer tyres: 3 mm
R
M+S tyres: 4 mm
R
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached..
Selecting, fitting and replacing tyres
Only fit tyres and wheels of the same type
R
and make.
Only fit approved tyres of the correct size
R
onto the wheels.
Tyres are coated with a protective layer at
R
the factory. Run in new tyres at moderate
speeds for the first 100 km. They only reach
their full performance after this distance.
Do not drive with tyres which have too little
R
tread depth. This otherwise significantly
reduces the traction on wet roads (aqua-
planing).
Replace the tyres after six years at the lat-
R
est, regardless of wear. This also applies to
the spare wheel.
