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.

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
289Breakdown assistance Z

that you use the proper size and type (summer
or winter tyre).
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 is available, for example, from a qualified specialist 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.
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 compres-
sor 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.
Comply with the manufacturer's safety instruc-
tions on the sticker on the tyre inflation com-
pressor. 290

First, tyre sealant is pumped into the tyre. The pressure may briefly rise to approximately
500 kPa (5.0 bar/73 psi).
Do not switch off the tyre inflation com-
pressor during this phase.
X Let the tyre inflation compressor run for a
maximum of five minutes. The tyre should
then have attained a pressure of at least
180 kPa (1.8 bar/26 psi).
If a tyre pressure of 180 kPa (1.8 bar/26 psi) has been achieved after five minutes: (Y page 292).
If a tyre pressure of 180 kPa (1.8 bar/26 psi) has not been achieved after five minutes:
(Y page 291).
If tyre sealant leaks out, make sure you clean the affected area as quickly as possible. It is pref-
erable to use clear water.
If you get tyre sealant on your clothing, have it
cleaned as soon as possible with perchloroethy-
lene.
Tyre pressure not reached If a pressure of 180 kPa (1.8 bar/26 psi) has not
been attained after five minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre. Flat tyre
291Breakdown assistance Z

Please note that tyre sealant may leak out
when unscrewing the filler hose.
X Very slowly drive forwards or reverse approx-
imately 10 m.
X Pump up the tyre again.
After a maximum of five minutes the tyre
pressure must be at least 180 kPa (1.8 bar/
26 psi). G
WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
tyre in this instance. Damaged tyres and a tyre pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tyre pressure reached G
WARNING
A tyre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed the specified maximum speed with a tyre that
has been repaired using tyre sealant.
The maximum speed for a tyre sealed with tyre
sealant is 80 km/h. The upper part of the
TIREFIT sticker must be affixed to the instru-
ment cluster where it will be easily seen by the
driver.
! After use, excess tyre sealant may run out of
the filler hose. This could cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit. H
Environmental note
Have the used tyre sealant bottle disposed of professionally, e.g. at a qualified specialist
workshop. If a tyre pressure of 180 kPa (1.8 bar/26 psi) has
been achieved after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre.
X Stow the tyre sealant bottle, the tyre inflation
compressor and the warning triangle.
X Pull away immediately.
X Stop after driving for approximately ten
minutes and check the tyre pressure with the tyre inflation compressor.
The tyre pressure must now be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tyre pressure is not reached
after driving for a short period, the tyre is too badly damaged. The tyre sealant cannot
repair the tyre in this instance. Damaged tyres and a tyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
i In your vehicle, you will find a sticker with
the Mercedes-Benz Service24h telephone
number, e.g. on the B-pillar on the driver's
side.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/19 psi). See the tyre pres-
sure table on the fuel filler flap for values.
X To increase the tyre pressure: switch on
the tyre inflation compressor. 292

Important safety notes
Work on the battery, e.g. removing or fitting,
requires specialist knowledge and the use of
special tools. Therefore, always have work on
the battery carried out at a qualified specialist
workshop. G
WARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP ®
(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
R when braking
R in the event of abrupt steering manoeuvres
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci- dent, contact a qualified specialist workshop
immediately. Do not drive any further. Always have work on the battery carried out at a
qualified specialist workshop.
Further information about ABS (Y page 62) and
ESP ®
(Y page 67). G
WARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle body to remove any existing electrostatic
build-up.
The highly flammable gas mixture is created
while the battery is charging and when jump-
starting.
Always make sure that neither you nor the bat-
tery is electrostatically charged. Electrostatic
charge is created, for example: R by wearing synthetic fibre clothing
R by friction between clothing and the seat
R when you pull or push the battery across car-
pet or other synthetic materials
R when you rub the battery with a cloth G
WARNING
During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
