cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed and stop the vehicle as
soon as possible to check the wheels and
tyres for damage. Hidden tyre damag e
could also be causing the unusual handling
characteristics. If you find no signs of dam-
age, have the wheels and tyres inspected
at a specialist workshop, for example at a
Mercedes-Benz Service Centre.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar, try to
do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
could get damaged. Direction of rotation
Direction of rotation Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
i You may fit a spare tyre *against th e
direction of rotation. Tyre tread
G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3 mm.
You should thus replace tyres that have
insufficient tread.
R winter tyres should be replaced when th e
tread depth is 4 mm or less because oth - erwise they no longer provide adequate
grip.
R the tread on a tyre may not wear evenly .
You should thus regularly check the tread
depth and the condition of the tread
across the entire width of all tyres. If nec -
essary, turn the steering wheel so that
you can see the tyre tread more easily.
You could otherwise lose control of the
vehicle and cause an accident due to the
reduced grip of the tyres on the road. Tyre pressures
G
Risk of accident
Tyre pressure that is either too high or too
low has a negative effect on the vehicle’ s
active safety, which could lead you to caus e
an accident. You should therefore regularly
check the pressure of all your tyres (includ -
ing the spare tyre*), particularly prior to
long trips, and correct the pressure as nec -
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure. Operation

Risk of injury
TIREFIT must not come into contact with
your skin, eyes or clothing .
R If TIREFIT comes into contact with your
eyes or skin, immediately rinse thor -
oughly with clean water.
R Change out of clothing which has come
into contact with TIREFIT immediately.
R If an allergic reaction occurs, consult a
doctor immediately.
Keep TIREFIT away from children .
R If TIREFIT is swallowed, immediately
rinse your mouth out thoroughly with
water and drink plenty of water.
R Do not induce vomiting. Consult a doctor
immediately.
R Do not inhale TIREFIT fumes .
i If TIREFIT leaks out, allow it to dry. It can
then be removed like a layer of film. If you get TIREFIT on your clothing, have it
cleaned as soon as possible with perchloro
-
ethylene. G
Risk of injury
Comply with the manufacturer's safety
instructions shown on the sticker on the
electric air pump.
i Your vehicle may be equipped with one of
two different air pumps. Version 1 can be
identified by the flap, behind which the
hose with the pressure gauge and cable are
located; version 2 has a pressure gauge
integrated in the electric air pump. Version

The electric air pump is switched on. The
tyre is inflated.
i First, TIREFIT is pumped into the tyre. The
pressure can briefly rise to around 5 bar.
Do not switch off the electric pump dur-
ing this phase.
X Let the electric pump run for five minutes.
The tyre should then have a pressure of at
least 1.8 bar.
! Do not operate the electric air pump for
longer than six minutes without a break.
Otherwise, it may overheat.
The air pump can be operated again once
it has cooled down.
If a pressure of 1.8 bar is not reached after
five minutes:
X Switch off and disconnect the electric ai r
pump and drive the vehicle forwards or
backwards approximately 10 m.
This distributes the TIREFIT more evenly.
X Remove TIREFIT filler bottle 1from the
electric pump.

Risk of accident
If a pressure of 1.8 bar is not achieved afte r
five minutes, the tyre is too badly damaged.
Do not drive any further. Consult a qualified
specialist workshop which has the neces-
sary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop.
If a tyre pressure of 1.8 bar is reached:
X Press on/off switch 4on the electric air
pump to 0.
The electric air pump is switched off.
X Disconnect the electric air pump and stow
it away .
X Fold up the warning triangle and stow it
away .
X Pull away immediately.
This distributes the TIREFIT more evenly
around the tyre.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the electric air pump. G
Risk of accident
If the tyre pressure is now lower than
1.3 bar, the tyre is too badly damaged. Do
not drive any further. Consult a qualified
specialist workshop which has the neces -
sary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop.
X If the tyre pressure is still at least 1.3 bar,
correct it (see fuel filler flap for values).
To increase the tyre pressure: switch on
the electric air pump.
To reduce the tyre pressure: open pres-
sure release screw aon pressure
gauge b.
X Drive to the nearest workshop and have the
tyre changed there.
X Have the TIREFIT kit replaced as soon as
possible at a qualified specialist workshop ,
e.g. at a Mercedes-Benz Service Centre. G
Risk of accident
