legal stipulations and factory recommenda-
tions at a Mercedes-Benz Service Centre.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle.
Notes on selecting, fitting and replacing
tyres
R
Only fit tyres and wheels of the same type
and make.
R
Only fit tyres of the correct size onto the
wheels.
R
After fitting new tyres, run them in at mod-
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
R
Fit new tyres on the front wheels first if
tyres of the same size are required on the
front and rear wheels.
R
Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel*.
R
Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
!
Store tyres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel.
Notes on regularly inspecting wheels
and tyres
R
Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels could cause a loss of tyre pressure.
R
Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (
Y
page 152). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
R
You should regularly check the pressure of
all the tyres, particularly prior to long trips,
and correct the pressure as necessary
(
Y
page 152).
Notes on driving
R
While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed and stop the vehicle as
soon as possible to check the wheels and
tyres for damage. Hidden tyre damage
could also be causing the unusual handling
characteristics. If you find no signs of dam-
age, have the wheels and tyres examined
at a specialist workshop, for example at a
Mercedes-Benz Service Centre.
R
When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, could get damaged.
