vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

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/luggage com-
partment floor (Y page 311). Depending on
the vehicle equipment, the vehicle tool kit is
on the left-hand side or the right-hand side in
the stowage well under the boot floor/
luggage compartment floor.
i Apart from some country-specific var-
iants, vehicles are not equipped with tyre-
changing tools. 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 tyre-changing tools can include,
for example:
R Jack
R Wheel chock
R Wheel wrench Where will I find...?

Preparing the vehicle
Your vehicle may be equipped with: R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 347)
Vehicle preparation is not necessary on
vehicles with MOExtended tyres.
R a TIREFIT kit (Y page 345)
R an emergency spare wheel (only for certain
countries) (Y page 390)
Information on changing/fitting a wheel
(Y page 373).
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 Secure the vehicle against rolling away
(Y page 180).
X If possible, bring the front wheels into the
straight-ahead position.
X Vehicles with AIRMATIC: make sure that
"normal" level is selected (Y page 202).
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 now have status
0 . This 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 344). Observe legal
requirements. MOExtended tyres (tyres with run-flat
characteristics)
General notes 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. The affected
tyre must not show any clearly visible dam-
age.
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 capa-
city and the speed index.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning system or tyre pressure monitoring
system.
If the pressure loss warning message
appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 280).
R check the tyre for damage.
R if driving on, observe the following notes.
The maximum driving distance is approx-
imately 80 km when the vehicle is partially
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 speed
R road condition
R outside temperature
The driving distance possible in run-flat mode may be reduced by extreme driving condi-
tions/manoeuvres, or it can be increased
through a moderate style of driving. Flat tyre
347Breakdown assistance
Page 351 of 417

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.
i When replacing one or all tyres, make
sure that you use only:
R the tyre size specified for the vehicle and
R tyre(s) marked "MOExtended"
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 that you use the
proper size and type (summer or winter
tyre).
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.
Important safety notes G
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. TIREFIT kit
Important safety notes TIREFIT is a tyre sealant.
You can use TIREFIT to seal punctures of up to
4 mm, particularly those in the tyre tread. You
can use TIREFIT at outside temperatures
down to Ò20 †. G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis- tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on a flat tyre.
There is a risk of an accident.
Do not drive any further. Contact a qualified
specialist workshop. G
WARNING
The tyre sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tyre sealant away
from children. There is a risk of injury.
If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from your skin
immediately with water.
R If the tyre sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tyre sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately. 348

R
Immediately change out of clothing which
has come into contact with tyre sealant.
R If an allergic reaction occurs, seek medical
attention immediately.
! Do not operate the tyre inflation com-
pressor for longer than eight 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.
