power socket in your vehicle .
X Turn the key to position 2(Y page 62) in
the ignition lock.
X Press on/off switch 3on the electric air
pump to I.
The electric air pump is switched on. The
tyre is inflated.
i First, TIREFIT is pumped into the tyre. The
pressure can briefly rise to around 5 bar.
Do not switch off the electric pump dur-
ing this phase.
X Let the electric pump run for five minutes.
The tyre should then have a pressure of at
least 1.8 bar.
! Do not operate the electric air pump for
longer than eight minutes at a time without
a break. Otherwise, it may overheat.
The air pump can be operated again once
it has cooled down. Practical advice

X Turn the jack back to its initial position and
store it and the rest of the vehicle tool kit
in the stowage compartment behind the

i When you are driving with the "Minispare"
emergency spare wheel* fitted, the tyre
pressure loss warning system* cannot
function reliably. MOExtended run-flat system*
The MOExtended run-flat system may only be
used in conjunction with the tyre pressure
loss warning system.
! The maximum permissible distance which
can be driven in run-flat mode depends on
the load in the vehicle. It is 50 km if the
vehicle is partially laden and 30 km if fully
laden.
The maximum range that can be driven in
emergency operation is measured from the
point at which the pressure loss warning
message appears in the multi-function dis-
play. You must not exceed a maximum speed of
80 km/h. G
Risk of accident
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 sud-
den 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 extent on the loads placed on the
vehicle. It can be shorter due to high
speeds, a heavy load, sudden acceleration
and/or manoeuvring, the road surface con-
dition, outside temperature, etc., or further,
if you drive carefully and conservatively.
Do not continue to drive in run-flat 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 run-flat mode, you must
have the wheel(s) checked for damage at a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. The faulty
tyre must be replaced in every case.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop.
i On a vehicle with MOExtended tyres, only
use MOExtended spare tyres. These must
be of the size specified for the vehicle. Practical advice

Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres which
have been approved specifically for your
vehicle by Mercedes-Benz. These tyres are
specially adapted for use with the control
systems, such as ABS or ESP ®
, and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Exten-
ded* (with run-flat characteristics)
If you use other tyres, Mercedes-Benz can-
not accept any responsibility for damage
which may occur. Information about tyres
can be obtained from any Mercedes-Benz
Service Centre.
i Vehicles with MOExtended run-flat sys-
tem are not equipped with the TIREFIT
kit* 34
.
Therefore, it is recommended that you
additionally equip your vehicle with the
TIREFIT kit* when fitting tyres that do not
feature run-flat properties, e.g. winter
tyres. i
A TIREFIT kit* is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre.
! If you fit tyres other than those tested and
recommended by Mercedes-Benz, charac-
teristics such as handling, noise levels and
fuel consumption, etc. may be adversely
affected. In addition, when driving with a
load, tyre dimensional 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.
i Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Service Centre.
You will find a table of tyre pressures on the
inside of your vehicle's fuel filler flap. You
will find further information about tyre pres-
sures in the "Operation" section
(Y page 178).
