stand behind the barrier.
X Get out of the vehicle. Pay attention to traffic
conditions when doing so.
X Close the driver's door.
X Place the warning triangle at a suitable dis-
tance (Y page 245). Observe legal require-
ments. TIREFIT kit
Important safety notes TIREFIT is a tyre sealant.
You can use TIREFIT to seal punctures of up to
4 mm, particularly those in the tyre tread. You
can use TIREFIT at outside temperatures down
to Ò20 †. G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis- tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on a flat tyre.
There is a risk of an accident.
Do not drive any further. Contact a qualified
specialist workshop. G
WARNING
The tyre sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tyre sealant away
from children. There is a risk of injury.
If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from your skin
immediately with water.
R If the tyre sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tyre sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
R Immediately change out of clothing which
has come into contact with tyre sealant.
R If an allergic reaction occurs, seek medical
attention immediately.
! Do not operate the tyre inflation compres-
sor for longer than ten minutes at a time with- out a break. It may otherwise overheat.
The tyre inflation compressor can be oper-
ated again once it has cooled down.
Comply with the manufacturer's safety instruc-
tions on the tyre inflation compressor label and
on the tyre sealant bottle. Flat tyre

Make sure that on/off switch ;on the tyre
inflation compressor is set to 0.
X Insert connector ?into the 12 V socket
(Y page 222).
X Select key position 2with the Start/Stop but-
ton (Y page 103). X
Press on and off switch ;on the tyre inflation
compressor to I.
The tyre inflation compressor is switched on.
The tyre is inflated.
First, tyre sealant is pumped into the tyre. The pressure may briefly rise to approximately
500 kPa (5 bar/73 psi).
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 attained a pressure of at least
180 kPa (1.8 bar/26 psi).
X In order to read the correct value from pres-
sure gauge B, switch the tyre inflation com-
pressor off briefly.
If a pressure of 180 kPa (1.8 bar/26 psi) has
been attained after five minutes, see "Tyre pres-
sure reached" (Y page 249).
If a tyre pressure of 180 kPa (1.8 bar/26 psi) has
not been attained after five minutes, see "Tyre
pressure not reached" (Y page 249).
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 pressure of 180 kPa (1.8 bar/26 psi) has not
been attained after five minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre.
Please note that tyre sealant may leak out
when unscrewing the filler hose.
X Very slowly drive forwards or reverse approx-
imately 10 m.
X Leave tyre sealant bottle :attached to the
flange.
X Pump up the tyre again.
After a maximum of five minutes the tyre
pressure must be at least 180 kPa (1.8 bar/
26 psi). G
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.
Tyre pressure reached G
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.
! After use, excess tyre sealant may run out of
the filler hose. This could cause stains. Flat tyre
249Breakdown assistance Z

Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
H
Environmental note
Have the used tyre sealant bottle disposed of professionally, e.g. at a qualified specialist
workshop.
If a tyre pressure of 180 kPa (1.8 bar/26 psi) has been attained after five minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre.
Leave the tyre sealant bottle attached to the
flange.
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.
Do not continue driving. Contact a qualified
specialist workshop.
i In your vehicle, you will find a sticker with
the Mercedes-Benz Service24h telephone
number, e.g. on the B-pillar on the driver's
side.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/19 psi). See the tyre pres-
sure table on the fuel filler flap for values.
X To increase the tyre pressure: switch on
the tyre inflation compressor.
X To reduce the tyre pressure: open release
screw C. X
When the tyre pressure is correct, unscrew
the filler hose from the valve of the sealed
tyre.
X Screw the valve cap onto the tyre valve of the
sealed tyre.
X Unscrew the tyre sealant bottle from the tyre
inflation compressor.
X Drive to the nearest qualified specialist work-
shop and have the tyre changed there.
X Have the tyre sealant bottle replaced as soon
as possible at a qualified specialist workshop.
X Have the tyre sealant bottle replaced every
four years at a qualified specialist workshop. Battery (vehicle)
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.
Further information about ABS (Y page 54) and
ESP ®
(Y page 57). 250
Battery (vehicle)Breakdown assistance

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 damageand 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 wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 262). If necessary, 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 the
valve against dirt and moisture. Do not fit any-
thing onto the valve other than the standard
valve cap or other valve caps approved for your vehicle by Mercedes-Benz. Do not fit any other
valve caps or systems, e.g. tyre pressure moni-
toring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 264).
Observe the notes on the emergency spare
wheel (Y page 273). The service life of tyres 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 can stipulate a specific tyre type for your
vehicle. Furthermore, the use of certain tyre
types in certain regions and areas of operation
can be highly beneficial. You can find further 262
OperationWheels and tyres

information regarding tyres at specialist tyre
retailers, at qualified specialist workshops or at any Mercedes-Benz Service Centre.
R Only fit 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.
R Only fit tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for the
first 100 km. They only reach their full per-
formance after this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aquaplan-
ing).
R Replace the tyres after six years at the latest,
regardless of wear.
Observe the notes on the emergency spare
wheel (Y page 273). 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 267). 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
an appropriate warning label in the driver's field
of vision. This can be obtained at a qualified
specialist workshop.
Under these circumstances, you should also
restrict the maximum design speed of the vehi- cle using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (Y page 130).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 264).
X Restart the tyre pressure monitor
(Y page 267).

Lowering the vehicle
G
WARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
! Vehicles with a collapsible emergency
spare wheel: Inflate the collapsible emer-
gency spare wheel using the tyre inflation
compressor before lowering the vehicle. The
rim could otherwise be damaged.
X Turn the crank of the jack anti-clockwise until
the vehicle is once again standing firmly on
the ground.
X Place the jack to one side. X
Tighten the wheel bolts evenly in a crosswise
pattern in the sequence indicated (: toA).
The specified tightening torque is 180 Nm.
X Turn the jack back to its initial position.
X Stow the jack and the rest of the tyre-change
tool kit in the load compartment again.
X Check the air pressure of the newly fitted
wheel and adjust accordingly.
Observe the recommended tyre pressure
(Y page 264).
If you are driving with the emergency spare
wheel fitted, the tyre pressure monitor cannot
function reliably. Only restart the tyre pressure
monitor when the defective wheel has been
replaced with a new wheel. All fitted wheels
must be equipped with functioning sensors. Wheel and tyre combinations
You can ask for information regarding permitted
wheel-tyre combinations at a Mercedes-Benz
Service Centre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle.
These are specially adapted to the control
systems, such as ABS or ESP ®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tyre dimension variations
could cause the tyres to come into contact
with the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tyres, wheels or accessories other than those tested and
approved.
Further information about wheels, tyres and
approved combinations can be obtained from
any qualified specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tyres. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tyres are fitted. Do not fit used tyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and therisk of damage to the wheels and tyres as a
result of driving over obstacles increases. 272
