Flat tyre
Preparing the vehicle
Your vehicle may be equipped with: R tyres with run-flat characteristics
(MOExtended tyres) (Y page 289)
Vehicle preparation is not necessary on vehi- cles with MOExtended tyres.
R a TIREFIT kit (Y page 288)
R an emergency spare wheel (certain countries
only) (Y page 318)
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.

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 Safeguard the vehicle against rolling away
(Y page 153).
X If possible, bring the front wheels into the
straight-ahead position.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove the
key from the ignition lock.
X Vehicles with KEYLESS-GO: open the driv-
er's door.

X Vehicles with KEYLESS-GO: remove the
Start/Stop button from the ignition lock
(Y page 132).
X Make sure that the passengers are not endan-
gered as they do so. Make sure that no one is
near the danger area while a wheel is being
changed. Anyone 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 traffic
conditions when doing so.
X Close the driver's door.
X Place the warning triangle at a suitable dis-
tance (Y page 287). Observe legal require-
ments. MOExtended tyres (tyres with run-flat
characteristics)
General notes 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. The affected tyre must not show
any clearly visible damage.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the tyre wall. You will find this marking next to the tyre
size designation, the load-bearing capacity and
the speed index.
MOExtended tyres may only be used in conjunc-tion with an activated tyre pressure loss warning
system or tyre pressure monitor.
If a pressure loss warning message appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 237)
R check the tyre for damage
R if driving on, observe the following notes
The driving distance possible in run-flat mode is
approximately 80 km when the vehicle is parti-
ally laden and approximately 30 km when the
vehicle is fully laden.
In addition to the vehicle load, the driving dis-
tance possible depends upon:
R vehicle speed
R road condition
R outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions/
manoeuvres, or it can be increased through a
moderate style of driving.
The driving distance possible 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.
When replacing one or all tyres, observe the fol-
lowing specifications for your vehicle's tyres:
R size
R type and
R the "MOExtended" mark
If a tyre has gone flat and cannot be replaced
with an MOExtended tyre, a standard tyre may
be used as a temporary measure. Make sure Flat tyre

WARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible gross weight of your vehicle, the:
R towing eye may be torn off
R car/trailer combination may swerve or
even overturn
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Details on the permissible gross vehicle weight
of your vehicle can be found on the vehicle iden-
tification plate (Y page 321).
! When Active Brake Assist, Distance Pilot
DISTRONIC or the HOLD function are activa-
ted, the vehicle brakes automatically in cer-
tain situations.
To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
R when towing away
R in a car wash
! Only secure the tow rope or towing bar to
the towing eyes. The vehicle may otherwise
be damaged. !
Observe the following points when towing
with a tow rope:
R secure the tow rope on the same side on
both vehicles.
R make sure that the tow rope is not longer
than legally permitted. Mark the tow rope in
the middle, e.g. with a white cloth
(30 x 30 cm). This makes other road users
aware that a vehicle is being towed.
R only secure the tow rope to the towing eye.
R observe the brake lamps of the towing vehi-
cle while driving. Always maintain a dis-
tance so that the tow rope does not sag.
R do not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
! Do not use the towing eye for recovery, this
could damage the vehicle. If in doubt, recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
! To tow vehicles with KEYLESS-GO, use the
key instead of the Start/Stop button. The
automatic transmission may otherwise
switch to position Pwhen you open the driv-
er's or front-passenger door which could
damage the transmission.
! Make sure that the electric parking brake is
released. If the electric parking brake is faulty,
visit a qualified specialist workshop.
! You may tow the vehicle for a maximum of
50km. A towing speed of 50 km/h must not
be exceeded. 298

WARNING
If the steering wheel lock is engaged, the vehi- cle can no longer be steered. There is a risk of
an accident.
Always switch on the ignition when towing
with a tow rope or a towing bar.
The automatic transmission automatically shifts
to position Pwhen you open the driver's or front-
passenger door or when you remove the key
from the ignition lock.
In order to ensure that the automatic transmis-
sion stays in position Nwhen towing away the
vehicle, you must observe the following points:
X Switch on the hazard warning lamps
(Y page 115).
X Make sure that the vehicle is stationary and
that the key is in position 0in the ignition lock.
X Turn the key to position 2in the ignition lock.
On vehicles with KEYLESS-GO, use the key
instead of the Start/Stop button
(Y page 132).
X Depress the brake pedal and keep it
depressed.
X Shift the transmission to position N.
X Release the brake pedal.
X Release the electric parking brake.
X Leave the key in position 2in the ignition lock.
In order to signal a change of direction when
towing the vehicle with the hazard warning
lamps switched on, use the combination switch
as usual. In this case, only the turn signals for
the desired direction flash. When the combina-
tion switch is reset, the hazard warning lamps
start flashing again.
It is important that you observe the safety
instructions when towing away your vehicle
(Y page 298). Towing the vehicle away with the rear
axle raised
! The ignition must be switched off if you are
towing the vehicle with the rear axle raised.
Intervention by ESP ®
could otherwise dam-
age the brake system. !
Vehicles with automatic transmission must
not be towed with the rear axle raised. The
car/trailer combination may otherwise
swerve or even overturn. Transporting the vehicle
Vehicles with automatic transmission !
When the vehicle is loaded for transport, the
front and rear axles must be stationary and on the same transportation vehicle. Positioning
over the connection point of the transport
vehicle is not permitted. The drive train may
otherwise be damaged.
All vehicles !
You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components. Otherwise, the
vehicle could be damaged.
The towing eye can be used to pull the vehicle
onto a trailer or transporter for transportation.
X Turn the key to position 2in the ignition lock.
X Shift the transmission to position N.
As soon as the vehicle is loaded:
X Safeguard the vehicle against rolling away by
applying the electric parking brake.
X Shift the transmission to position P.
X Turn the key to position 0in the ignition lock
and remove it.
X Secure the vehicle. 300
