Vehicles with alloy wheels and hub caps On vehicles with alloy wheels and hub caps, a
socket is also provided.
Flat tire
Preparing the vehicle Your vehicle may be equipped with: R
MOExtended tires (tires with run-flat proper-
ties) ( Y
page 278)
Vehicle preparation is not necessary on vehi-
cles with MOExtended tires R
a TIREFIT kit ( Y
page 277)R
an emergency spare wheel ( Y
page 317)
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with a TIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. A TIREFIT kit may be obtained from
a qualified specialist workshop.

Stop the vehicle on solid, non-slippery and
level ground, as far away as possible from
traffic. X
Switch on the hazard warning lamps. X
Secure the vehicle against rolling away
( Y
page 141).X
If possible, bring the front wheels into the
straight-ahead position. X
Vehicles with AIRMATIC: make sure that "nor-
mal" level is selected ( Y
page 159).X
Switch off the engine. X
Remove the SmartKey from the ignition lock.
or, on vehicles with KEYLESS ‑ GO:X
Open the driver's door.
T he vehicle electronics now have status 0 .
This is the same as the SmartKey having been
removed. X
Remove the Start/Stop button from the igni-
tion lock ( Y
page 123).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.
MOExtended tires (tires with run-flat
properties)
General notes With MOExtended tires (tires 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 tires. The affected tire must not show
any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-bear-
ing capacity and the speed index ( Y
page 307).
MOExtended tires may only be used in conjunc-
tion with an active tire pressure loss warning
system or with an active tire pressure monitor.
If a pressure loss warning message appears
in the multifunction display: R
observe the instructions in the display mes-
sages ( Y
page 221). R
check the tire for damage. R
if driving on, observe the following notes.
The driving distance possible in run-flat mode is
approximately 50 miles (80 km) when the vehi-
cle is partially laden. When the vehicle is fully
laden it is approximately 19 miles (30 km).
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 p ossible in run-flat mode
may be reduced by extreme driving conditions
or maneuvers, 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 tire pressure loss
warning appears in the multifunction display.
You must not exceed a maximum permissible
speed of 50 mph (80 km/h).278

Towing a vehicle with both axles on
the ground It is important that you observe the safety
instructions when towing away your vehicle
( Y
page 287).
The automatic transmission automatically shifts
to position P when you open the driver's or front-
passenger door or when you remove the Smart-
Key from the ignition lock. In order to ensure
that the automatic transmission stays in posi-
tion N when towing the vehicle, you must
observe the following points: X
Make sure that the vehicle is stationary. X
Turn the SmartKey to position 2 in the ignition
lock.
On vehicles with KEYLESS-GO, use the Smart-
Key instead of the Start/Stop button
( Y
page 124). X
Depress and hold the brake pedal. X
Shift the automatic transmission to position
N . X
Release the brake pedal. X
Release the parking brake. X
Switch on the hazard warning lamps
( Y
page 107). X
Leave the SmartKey in position 2 in the igni-
tion 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. After resetting the
combination switch, the hazard warning lamp
starts flashing again. Towing the vehicle with the rear axle
raised
! Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised, as
doing so will damage the transmission.
! Vehicles with automatic transmission must
not be towed with the rear axle raised. The
vehicle/trailer combination may otherwise
swerve or even roll over.
Transporting the vehicle
4MATIC vehicles/vehicles with auto-
matic 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 transporting pur-
poses. X
Turn the SmartKey to position 2 in the ignition
lock. X
