Risk of accident
Do not fit anything else to the tyre valve other
than the standard valve cap .Inparticular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve
is kept open continuously, which may lead to
air loss. G
Ris
kofa ccident
Should the tyre pressure drop repeatedly:
R check the tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only a valve cap approved
by Mercedes-Ben zhas been fitted on the
tyre valve.
Tyre pressures that are to olow have a nega-
tive effect on vehicle safety, which could lead
to your causing an accident.
If possible, you should only correc ttyre pres-
sures when the tyres are cold. Depending on
the ambien ttemperature, the speed you are
driving at and the load on the tyres, the tyre
temperature and thus the tyre pressure may
change by approximately 0.1 bar per 10 †.
Take this into account when checking the
pressure of warm tyres and only correct it if
it is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effec tonhandling charac-
teristics and thus the driving safety (e.g. by
causing aquaplaning) H
Environmental note
Chec kthe tyre pressure regularly, at least
every 14 days. Tyre pressure monitor
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you when
the pressure drops in one or more of the
tyres. The tyre pressure monitor only func-
tions if the correct wheel electronics units are
fitted to all wheels. G
Risk of accident
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. The table
on the inside of the fuel filler flap will help you
decide whether the tyre pressures should be
corrected.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Do not
make any sudden steering movements when
doing so.
i The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.

Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only if
they have the same dimensions: for example
size, offset, etc.
After every wheel interchange/change, have
the tightening torque checked at a qualified
specialist workshop that has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
The wheels could work loose if they are not
tightened to a torque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wear patterns on the front and rear tyres
differ, depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the tyre shoulders and
the rear tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5000 km to 10,000 km depending on
the degree of tyre wear. Do not reverse the
direction of tyre rotation.
Cleant he contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and
reactivate the tyre pressure monitor if neces-
sary.
! As your vehicle is fitted with a tyre pres-
sure monitor, electronic components are
located in the wheel. Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Winter operation
Please bear the following in mind
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 275). Winter tyres
Use winter tyres at temperatures below
+7 ˚C and in wintry road conditions. Only
winter tyres displaying the 0001snowflake
symbol in addition to the M+S marking pro-
vide optimum grip in wintry road conditions.
Only these tyres will allow the ABS and
ESP ®
driving safety systems to function opti-
mally in winter, as these tyres have been
designed specifically for driving on snow.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with a tread depth of less than
4mmm ust be replace dimmediately. They are
no longer suitable for winter use and can no
longer provide sufficient grip. This could
cause you to lose control of yourv ehicle and
cause an accident.
Always observe the maximum permissible
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permissible speed than that
of the vehicle, affix an appropriate warning
sign in the driver's field of vision. This can be Winter operation

Failure to observe these notes may result
in damage to the engine, electrical systems
and transmission.
Driving abroad
Please bear the following in mind
An extensive Mercedes–Benz Service net-
work is also available in other countries. The
Service Hotline's curren ttelephone numbers
for use when you are abroad are to be found
in the "Service24h" chapter of the Service
Booklet.
Only low-octane fuel is available in certain
countries.

grades on (Y page 266). Symmetrical dipped-beam head-
lamps
G
Risk of injury
Xenon bulbs are under high voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric con-
tacts on xenon bulbs. Therefore, do not
remove the cover on xenon bulbs.
Do not change xenon headlamps yourself, but
have them replaced at a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
Switching to symmetrical dipped beam
when driving abroad: If your journey takes
you to countries where vehicles are driven on
the opposite side of the road to the country
in which the vehicle is registered, your head-
lamps must be switched to symmetrical
dipped beam. This prevents oncoming traffic
from being dazzled.
Before entering such countries, have the
headlamps switched over at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre, as close as possible to the
border. When using symmetrical lights, the
edge of the carriageway is not illuminated as
widely and as far ahead as normal.
Switching back to asymmetrical dipped
beam after your return: After returning from
such countries, have the headlamps switched
over at a qualified specialist workshop, e.g. a
Mercedes-BenzS ervice Centre, as close as
possible to the border. Service
