the front of the driver's seat. X
Pull tab :upwards.
X Remove fire extinguisher ;.
i Have fire extinguisher ;refilled after
each use and checked every one to two
years. It may otherwise fail in an emer-
gency.
Observe the legal requirements for each
individual country. Vehicle tool kit
General notes The vehicle tool kit can be found in the stow-
age well under the boot floor.
i
Apart from certain country-specific varia-
tions, vehicles are not equipped with a tyre-
change tool kit. Some tools for changing a
wheel are specific to the vehicle. For more
information on which tools are required to
perform a wheel change on your vehicle,
consult a qualified specialist workshop.
Necessary wheel-changing tools can
include, for example:
R jack
R wheel chock
R wheel wrench Vehicles with
aTIREFIT kit :
Centring pin

Preparing the vehicle
Information on changing a wheel/fitting
(Y page 346).
Vehicle preparation is not necessary on vehi-
cles with MOExtended tyres.
Your vehicle may be equipped with:
R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 324)
R a TIREFIT kit (Y page 325)
R an emergency spare wheel (only for certain
countries) (Y page 363)
X Stop the vehicle as far away as possible
from traffic on solid, non-slippery and level
ground.
X Switch on the hazard warning lamps.
X Apply the parking brake.
X Bring the frontw heels into the straight-
ahead position.
X Shift the transmission to position P.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove
the key from the ignition lock.
X Vehicles with KEYLESS-GO: open the
driver's door.
The on-board electronics have status 0,
which is the same as the key having been
removed. X
Vehicles with KEYLESS-GO: remove the
Start/Stop button from the ignition lock
(Y page 159).
X All occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area while a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Get out of the vehicle. Pay attention to traf-
fic conditions when doing so.
X Close the driver's door.
X Place the warning triangle a suitable dis-
tance away (Y page 322). Observe legal
requirements. MOExtended tyres (tyres with run-flat
characteristics)

WARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when corner-
ing, accelerating quickly and when braking.
There is a risk of accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving manoeu-
vres, and driving over obstacles (kerbs, pot-
holes, off-road). This applies in particular to a
laden vehicle.
Stop driving in emergency mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in emergency mode, have the
wheel rims checked at a qualified specialist
workshop with regard to their further use. The
faulty tyre must be replaced.
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive 324

other obstacles. If it is necessary to drive over
kerbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
may be damaged. 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.
Regularly check the wheels and tyres of your
vehicle for damage at least once a month, as
well as 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 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 341). 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
anything onto the valve other than the stand-
ard valve cap or other valve caps approved by
Mercedes-Benz for your vehicle. Do not fit any
other valve caps or systems, e.g. tyre pres-
sure monitoring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 343).
Observe the notes on the emergency spare
wheel (Y page 363). The service life of tyres depends on various
factors, including the following:
R
driving style
R tyre pressure
R tyre mileage 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 particular
where 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
R Only fit tyres and wheels of the same type
and make.
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
performance after this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aqua-
planing).
R Replace the tyres after six years at the lat-
est, regardless of wear. Operation
341Wheels and tyres Z

Observe the notes on the emergency spare
wheel (Y
page 363). MOExtended tyres (tyres with run-flat
characteristics)
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning system or with an active tyre pres-
sure monitor and on wheels specifically tes-
ted by Mercedes-Benz.
Notes on driving with MOExtended tyres with
a flat tyre (Y page 324).
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit
if you fit tyres that do not feature run-flat
characteristics, e.g. winter tyres. A TIREFIT
kit can be obtained from a qualified spe-
cialist 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 346). Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticity and therefore traction and
braking power. Change the tyres on your vehi-
cle 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. M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than
4mma re 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-seaso ntyres .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 pro-
vide the best possible grip in wintry road con-
ditions.
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 char-
acteristics.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres that have a lower maxi-
mum permissible speed than that of the vehi-
cle, affix a corresponding 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 speed of the vehicle
using permanent SPEEDTRONIC so that it
does not exceed the maximum permissible
speed for the M+S tyres (Y page 188).
When you have fitted the M+S tyres:
X Check the tyre pressures (Y page 343).
X Restart the tyre pressure loss warning sys-
tem (Y page 345).

gency spare wheel, see (Y page 363).342
