Important safety notes

G WARNING
Tyres, wheels or accessories which have not
been approved by Mercedes-Benz for your
vehicle or are not used as they should be, can
impair driving safety. As a result, you could
cause an accident. Before purchasing and
using them, enquire about their suitability,
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.

Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Service Centre.
Operation
Notes on driving
While driving, pay attention to vibrations,
R
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 immediately. Stop the
page 22).
Y
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 damage, have the wheels and tyres
examined at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre.
When parking your vehicle, make sure that
R
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, can get damaged.
Notes on regularly inspecting wheels
and tyres
Regularly check the wheels and tyres of
R
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 can cause a loss of tyre pressure.
Regularly check the tyre tread depth and
R
the condition of the tread across the whole
width of the tyre (
Y
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
All wheels must have a valve cap to protect
R
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.
Regularly check the pressure of all the tyres
R
including the emergency spare wheel or the
spare wheel, particularly prior to long trips,
and correct the pressure as necessary
