Do not switch off the tyre inflation com-
pressor during this phase.
X Let the tyre inflation compressor run for a
maximum of ten minutes. The tyre should
then have reached a pressure of at least
200 kPa (2.0 bar/29 psi).
If a pressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten minutes, see "Tyre pres- sure reached" (Y page 329).
If a tyre pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten minutes, see "Tyre
pressure not reached" (Y page 329).
If tyre sealant leaks out, make sure you clean the affected area as quickly as possible. It is pref-
erable to use clear water.
If you get tyre sealant on your clothing, have it
cleaned as soon as possible with perchloroethy-
lene.
Tyre pressure not reached If a tyre pressure of 200 kPa (2.0 bar/29 psi) has
not been reached after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre.
Tyre sealant may leak out when the filler hose
is unscrewed.
X Very slowly drive forwards or reverse approx-
imately 10 m.
X Pump up the tyre again.
After a maximum of ten minutes, the tyre
pressure must be at least 200 kPa (2.0 bar/

WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
tyre in this instance. Damaged tyres and a tyre pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.

WARNING
A tyre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed the specified maximum speed with a tyre that
has been repaired using tyre sealant.
The maximum permissible speed for a tyre
sealed with tyre sealant is 80 km/h. The upper
part of the TIREFIT sticker must be affixed to the
instrument cluster where it will be easily seen by
the driver.
If a tyre pressure of 200 kP a(2.0 bar/29 psi) has
been reached after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre.
Tyre sealant may leak out when the filler hose
is unscrewed.
X Stow the tyre sealant bottle, the tyre inflation
compressor and the warning triangle.
X Pull away immediately.
X Stop after driving for approximately ten
minutes and check the tyre pressure with the
tyre inflation compressor.
The tyre pressure must now be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tyre pressure is not reached
after driving for a short period, the tyre is too badly damaged. The tyre sealant cannot
repair the tyre in this instance. Damaged tyres and a tyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is a risk of accident.

12 V battery – important safety notes
Work on the battery, e.g. removing or fitting,
requires specialist knowledge and the use of
special tools. Therefore, always have work on
the battery carried out at a qualified specialist
workshop. G
WARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP ®
(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
R when braking
R in the event of abrupt steering manoeuvres
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci- dent, contact a qualified specialist workshop
immediately. Do not drive any further. Always have work on the battery carried out at a
qualified specialist workshop.

tures. There is a risk of an accident.
Turn on ESP ®
and adapt your driving style
accordingly. When the outside temperature
falls below 10 †, use M+S tyres.
i Different driving styles may lead to higher
levels of tyre wear, meaning the tyres may
wear down to the minimum tyre tread depth
after less mileage. 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.
Check wheels and tyres for damage at least
once a month. Check wheels and tyres after
driving off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
Pay particular attention to damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on the
wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width of
the tyre on all tyres (Y page 343). If necessary,
turn the front wheels to full lock to make it easier to inspect the inner side of the tyre surface.
All wheels must have a valve cap to protect the
valve against dirt and moisture. Do not fit any-
thing onto the valve other than the standard
valve cap or other valve caps specially approved for your vehicle by Mercedes-Benz. Do not fit
any other valve caps or systems, e.g. tyre pres-
sure monitors.
Check the pressure of all tyres regularly as well as prior to long trips. Adjust the tyre pressure as
necessary (Y page 345).
Observe the notes on the emergency spare
wheel (Y page 356). The service life of a tyre depends on various fac-
tors, including the following:
R Driving style
R Tyre pressure
R Mileage Notes on the 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 particularwhere 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:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the
tyre load rating and speed rating required for your vehicle.
Pay special attention to country-specific
requirements for tyre approval. These require-
ments may stipulate a specific tyre type for your
vehicle. Furthermore, the use of a specific tyre
type in certain regions and areas of operation
can be highly beneficial. You can find further Operation
343Wheels and tyres Z
information regarding tyres at specialist tyre
retailers, at qualified specialist workshops or at any Mercedes-Benz Service Centre.
R Use only tyres and wheels of the same type
and make.
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics)" section
(Y page 326).
R Fit only tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for the
first 100 km. They reach their full perform-
ance only after this distance.
R Do not drive with tyres that have too little
tread depth. This significantly reduces trac-
tion on wet roads (aquaplaning).
R Replace the tyres after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 356). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat char- acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one or more tyres.
MOExtended tyres may be used only in conjunc-tion with an activated tyre pressure loss warning
system or with an activated tyre pressure mon-
itor and only on wheels specifically tested by
Mercedes-Benz.
Notes on driving with MOExtended tyres with a
flat tyre (Y page 326).
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that
do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop. Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter. Observe the notes in the "Changing a wheel"
section (Y page 350). Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle to
M+S tyres. Using summer tyres at very cold
temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage. 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 damageand replace any damaged tyres immediately. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified
by the M+S marking.
Only winter tyres bearing the isnowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions. Only these tyres will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyre sthat have a lower maximum
permissible speed than that of the vehicle, affix 344
