Preparing the vehicle
Your vehicle may be equipped with:
R a TIREFIT kit
R an emergency spare wheel
R a spare wheel
R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 345)
i Vehicle preparatio nis not necessary on
vehicles with MOExtended tyres.
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
properties, e.g. winter tyres. A TIREFIT kit
can be obtained from a Mercedes-Benz
Service Centre. 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 Firmly depress the parking brake.
X Bring the front wheels into the straight-
ahead position.
X Vehicles with manual transmission:
engage first or reverse gear.
X Vehicles with automatic transmission:
move the selector lever to 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 153).
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 whilst 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 (Y page 334) a
suitable distance away. Observe legal
requirements. TIREFIT kit
Using the TIREFIT kit You can use the TIREFIT kit to seal small
punctures, particularly those in the tyre tread. Flat tyre

in your vehicle (Y page 317).
X Turn the key to position 1(Y page 153) in
the ignition lock.
X Press on/off switch =on the tyre inflation
compressor to I.
The tyre inflation compressor is switched
on. The tyre is inflated.
i First, TIREFIT is pumped into the tyre .The
pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tyre inflation com-
pressor during this phase.
X Allow the tyre inflation compressor to run
for five minutes. The tyre should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
! Do not operate the tyre inflation com-
pressor for longer than six minutes at a
time without a break. It may otherwise
overheat. The tyre inflation compressor can be oper-
ated again once it has cooled down.
If a pressure of 180 kPa (1.8 bar/26 psi) has
been achieved after five minutes, see
(Y page 340).
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been achieved after five minutes, see
(Y page 340).

X Turn the key to position 1(Y page 153) in
the ignition lock.
X Press on/offs witch?on the tyre inflation
compressor to ON.
The tyre inflatio ncompressor is switched
on. The tyre is inflated.
i First, TIREFIT is pumped into the tyre. The

ated again once it has cooled down.
If a pressure of 180 kPa (1.8 bar/26 psi) has
been achieved after five minutes, see

If a pressure of 180 kPa (1.8 bar/26 psi) has
not been achieved after five minutes, see

Tyre pressure of at least 180 kPa
(1.8 bar/26 psi) not reached If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has not been achieved:
X
Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
X Very slowly drive forwards or reverse
approximately 10 m.
X Pump up the tyre again. G
WARNING
If after five minutes apressure of 180 kPa
(1.8 bar/26 psi) cannot be achieved, the tyre
is too severely damaged.
Do not drive any further. Consult a qualified
specialist workshop which 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.
Tyre pressure of 180 kPa (1.8 bar/
26 psi) is reached X
Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
! After use, excess TIREFIT may run out of
the filler hose. This may cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
X Stow the tyre sealant bottle, the tyre infla-
tion compresso rand the warning triangle.
X Pull away immediately . G
WARNING
Do not exceed the maximu mspeed of
80 km/h.
The "max. 80 km/h" label must be affixed in
the driver's field of vision.
The vehicle's handling characteristics may be
affected.
X Stop after driving for approximately ten
minutes and chec kthe tyre pressure with
the tyre inflation compressor. G
WARNING
If the tyre pressure is less than 130 kPa
(1.3 bar/20 psi), the tyre is too severely dam-
aged. Do not drive any further. Consult a
qualified specialist workshop which has the
necessary specialist knowledge and tools to 340

X
Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated
(: toA ). The tightening torque must be
130 Nm. G
WARNING
Have the tightening torque checked immedi-
ately after a wheel is changed. The wheels
could work loose if they are not tightened to
a torque of 130 Nm.
X Turn the jack back to its initial position and
store it together with the rest of the tyre-
change tool kit in the boot/luggage com-
partment.
X Transport the faulty wheel in the boot/lug-
gage compartment.
or
X Depending on the size of the wheel, you
may also be able to secure the faulty wheel
in the spare wheel well. In this case, you
will have to remove the stowage well casing
from the spare wheel well and stow it
securely in the boot/luggage compart-
ment.
i When you are driving with the collapsible
emergency spare wheel fitted, the tyre
pressure loss warning system or the tyre
pressure monitor cannot function reliably.
Only restart the tyre pressure loss warning
system/tyre pressure monitor when the
defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: all fit-
ted wheels must be equipped with func- tioning sensors. The defective wheel
should no longer be in the vehicle. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allow you to continue driving the
vehicle even when one or more tyres lose all
air pressure.
MOExtended tyres may only be used in con-
junction with the activated tyre pressure loss
warning system or with the tyre pressure
monitor.
The maximum permissible distance which
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure loss warning
appears in the multifunction display.
You must not exceed a maximum speed of
80 km/h. G
WARNING
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to a large
exten tonthe loads placed on the vehicle. It
can be shorter due to high speeds, a heavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc.,
or further if you drive carefully and conserva-
tively. Flat tyre
