Preparing the vehicle
Your vehicle may be equipped with:
R MOExtended tyres (tyres with run-flat char-
acteristics) ( Y page 298)
Vehicle preparation is not necessary on
vehicles with MOExtended tyres.
R a TIREFIT kit ( Y page 297)
R an emergency spare wheel (only for certain
countries)
Information on changing/fitting a wheel
( Y page 325).
XStop the vehicle as far away as possible
from traffic on solid, non-slippery and level
ground.XSwitch on the hazard warning lamps.XSecure the vehicle against rolling away
( Y page 162).XIf possible, bring the front wheels into the
straight-ahead position.XSwitch off the engine.XRemove the key from the ignition lock.XAll occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.XMake 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.XGet out of the vehicle. Pay attention to traf-
fic conditions when doing so.XClose the driver's door.XPlace the warning triangle a suitable dis-
tance away ( Y page 296). Observe legal
requirements.
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.
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.
If the pressure loss warning message
appears in the multifunction display:
R Observe the instructions in the display
messages ( Y page 248).
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.
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.
298Flat tyreBreakdown assistance

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 notesGWARNING
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 notesGWARNING
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 accident.
Do not drive any further. Contact a qualified
specialist workshop.
GWARNING
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.
R Immediately change out of clothing which
has come into contact with tyre sealant.
R If an allergic reaction occurs, seek medical
attention immediately.
Using the TIREFIT kit
TIREFIT is a tyre sealant.
You can use TIREFIT to seal punctures of up
to 4 mm, particularly those in the tyre tread.

GWARNING
A flat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tyres without run-flat characteristics:
R do not drive with a flat tyre.
R immediately replace the flat tyre with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyres (tyres
with run-flat characteristics).
Accessories that are not approved for your
vehicle by Mercedes-Benz or that are not
being used correctly can impair operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and enquire about:
R suitability
R legal stipulations
R factory recommendations
Information on dimensions and types of
wheels and tyres for your vehicle can be
found ( Y page 329).
Information on air pressure for the tyres on
your vehicle can be found:
R on the tyre pressure label on the fuel filler
flap
R under "Tyre pressure"
Modification work on the brake system and
wheels is not permitted. The use of wheel
spacers or brake dust shields is not permit-
ted. This invalidates the general operating
permit for the vehicle.
i Further information on wheels and tyres
can be obtained at any qualified specialist
workshop.
Operation
Information on driving
R Check the tyre pressures when the vehicle
is heavily laden and, if necessary, adjust.
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed immediately. Stop the
vehicle as soon as possible to check the

run-flat characteristics)" section
( Y page 298).
R Only fit tyres of the correct size onto the
wheels.
R Run in new tyres at moderate speeds for
the first 100 km. They only reach their full
performance after this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aqua-
planing).
R Replace the tyres after six years at the lat-
est, regardless of wear.
Observe the notes on the emergency spare
wheel ( Y page 331).
MOExtended tyres (tyres with run-flat
characteristics)
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.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning system and only on wheels specifi-
cally tested by Mercedes-Benz.
Notes on driving with MOExtended tyres with
a flat tyre ( Y page 298).
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.
Winter operation
General notes
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing a wheel"
section ( Y page 324).
Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticity and therefore traction and
braking power. Change the tyres on your vehi-
cle to M+S tyres . Using summer tyres at very
cold temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage.
M+S tyres
GWARNING
M+S tyres with a tyre tread depth of less than
4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
At temperatures below +7 †, use winter tyres
or all-season tyres. Both types of tyre are
identified by the M+S marking.
Only winter tyres bearing the i snowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road con-
ditions. Only these tyres will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. These tyres have
been developed specifically for driving in
snow.
Use M+S tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics.
Always observe the maximum permissible
speed specified for the M+S tyres you have
fitted.
If you fit M+S tyres that have a lower maxi-
mum permissible speed than that of the vehi-
cle, affix an appropriate warning sign in the
driver's field of vision. This can be obtained
at a qualified specialist workshop.
