Preparing the vehicle
Your vehicle may be equipped with:
R a TIREFIT kit
R an emergency spare wheel
R MOExtended tyres (tyres with run-fla tchar-
acteristics) (Y page 289)
i Vehicle preparation is not necessary on
vehicles with MOExtended tyres.
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
properties, e.g. winter tyres. You can obtain
aT IREFIT kit from aMercedes-Benz Service
Centre, for example.
X Vehicles with AIRMATIC: make sure that
"normal" level is selected (Y page 167).
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 Bring the fron twheels into the straight-
ahead position.
X Move the DIRECT SELECT lever to P.
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 have status 0,
which 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 129). 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 whilst 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 (Y page 278) a
suitable distance away.O bserve legal
requirements. TIREFIT kit
Using the TIREFIT kit You can use the TIREFIT kit to seal small
punctures, particularly those in the tyre tread.
You can use TIREFIT at outside temperatures
down to -20 †.
G
Risk of accident
In the following situations, your safety is at
particular risk as tyre sealant is unable to pro-
vide sufficient breakdown assistance:
R there are cuts or punctures in the tyre
greater than 4 mm.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on a flat tyre.
Do not drive any further. Consult a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related system smust be carried out
at a qualified specialist workshop. Flat tyre

i
First, TIREFIT is pumped into the tyre .The
pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tyre inflation com-
pressor during this phase.
X Allow the tyre inflation compressor to run
for five minutes. The tyre should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
! 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.
If a pressure of 180 kPa (1.8 bar/26 psi) has
been achieved after five minutes, see
(Y page 283).
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been achieved after five minutes, see
(Y page 283).
Tyre pressure of 180 kPa (1.8 bar/
26 psi) is not reached If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has not been achieved:
X Press the on/off switch on the tyre inflation
compressor to 0.
The tyre inflation compressor is switched
off.
X Unscrew the filler hose from the valve.
X Very slowly drive forwards or reverse
approximately 10 m.
X Pump up the tyre again. G
Risk of accident
If after five minutes apressure of 180 kPa
(1 8 bar/26 psi) cannot be achieved, the tyre
is too severely damaged.
Do not drive any further. Consult a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
Tyre pressure of 180 kPa (1.8 bar/
26 psi) is reached X
Press the on/off switch on the tyre inflation
compresso rto0.
The tyre inflation compressor is switched
off.
X Remove the tyre sealant bottle from the
wheel.
! After use, excess TIREFIT may run out of
the filler hose. This may cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X Pull away immediately. G
Risk of accident
Do not exceed the maximum speed of
80 km/h.
The "max. 80 km/h" label must be affixed in
the driver's field of vision.
The vehicle's handling characteristics may be
affected.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the tyre inflation compressor. G
Risk of accident
If the tyre pressure is less than 130 kPa
(1.3 bar/20 psi), the tyre is too severely dam-
aged. Do not drive any further. Consult a
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use aMercedes-Benz
Service Centre for this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
specialist workshop. Flat tyre

X
Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated
(: toA ). The tightening torque must be
130 Nm. G
Risk of accident
Have the tightening torque checked immedi-
ately after a wheel is changed. The wheels
could work loose if they are not tightened to
a torque of 130 Nm.
X Turn the jack back to its initial position and
store it together with the rest of the vehicle
tool kit in the stowage well under the boot
floor.
For further information on stowing the col-
lapsible emergency spare wheel:
(Y page 280).
i When you are driving with the collapsible
emergency spare wheel fitted, the tyre
pressure loss warning system or the tyre
pressure monitor cannot function reliably.
Only restart the tyre pressure loss warning
system/tyre pressure monitor when the
defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: all fit-
ted wheels must be equipped with func-
tioning sensors and the defective wheel
should no longer be in the vehicle. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres featuring run-flat
characteristics) enable your vehicle to con-
tinue its journey even with a complete loss of
tyre pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with the activated tyre pressure loss
warning system or with the activated tyre
pressure monitor.
The maximum permissible distance which
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
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. G
Risk of accident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to a large
exten tonthe loads placed on the vehicle. It
can be shorter due to high speeds, a heavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc.,
or further if you drive carefully and conserva-
tively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake. Flat tyre

is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in run-flat mode, you must have
the wheel(s) checked for damage at a quali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the wor krequired. The faulty tyre must be
replaced in every case.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
i When replacing one or all tyres, make
sure that you only use tyres marked
MOExtended and of the specified size for
the vehicle.
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
properties, e.g. winter tyres. A TIREFIT kit
can be obtained from a Mercedes-Benz
Service Centre. Battery
Important safety notes
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period.
To preven tdamage from corrosion, only
replace the battery with one that has a central
ventilation cover.
Only replace a battery with a battery that has
been recommended by Mercedes-Benz. Consult a Mercedes-Ben
zService Centre if
you wish to leave your vehicle parked up for
a long period of time. G
Risk of injury
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the battery.
Avoid creating sparks.
Battery acid is caustic.
Avoid contact with the skin,
eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and a face
mask.
Immediately rinse acid
splashes off with clean
water. Consult a doctor if
necessary.
Wear eye protection.
Keep children away.
Observe this Owner's Man-
ual.

Tyre tread
G
Ris
kofa ccident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4mmorless as they no lon-
ger provide adequate grip.
R the tread on a tyre may not wear evenly.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the fron twheels to full lock in order to
inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Notes on selecting, fitting and replac-
ing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fittingn ew tyres, run them in at mod-
erate speeds for the first 100 km, as they
only reach their full performance after this
distance.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the emergency spare wheel/spare wheel. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allow you to continue driving the vehicle even when one or more tyres lose all
air pressure.
MOExtended tyres may only be used in con-
junction with the activated tyre pressure loss
warning system or with the activated tyre
pressure monitor and on wheels specifically
tested by Mercedes-Benz.
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 the TIREFIT
kit if you fit tyres that do not feature run-
flat properties, e.g. winter tyres. You can
obtain a TIREFIT kit from a Mercedes-Benz
Service Centre, for example.
You will find notes on driving with a flat tyre
in the "Breakdown assistance" section
(Y page 289). Winter operation
Please bear the following in mind
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 309). Driving with summer tyres
At temperatures below +7 †, summer tyres
lose elasticity and therefore traction and
braking power –change the tyres on your
vehicle to M+S tyres. Using summer tyres at
very cold temperatures could cause tears to
form, thereby damaging them permanently.
Mercedes-Ben zcannot accept responsibility
for this type of damage. M+S tyres
At temperatures below +7 †, use winter tyres
or all-season tyres. Both types of tyre are
identified by the M+S marking. Winter operation

Risk of accident
The tyre pressure loss warning system can
only give reliable warnings if you have set the
correct tyre pressure.
If an incorrect tyre pressure is set, these
incorrect values will be monitored.
At yre with insufficien tpressure results in
vehicle instability when driving, thus increas-
ing the risk of an accident.

Important safety notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you if the
pressure drops in one or more of the tyres.
The tyre pressure monitor only functions if
the correct wheel electronics units are fitted
to all wheels.
G
Risk of accident
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. The table
on the inside of the fuel filler flap will help you
decide whethe rthe tyre pressures should be
corrected.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the Tyre pressure
