Windscreen wiper blades
G
Risk of accident
The windscreen will no longer be wiped prop-
erly if the wiper blades are worn. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident. Replace
the wiper blades twice a year, ideally in spring
and autumn. G
Risk of accident
The wiper arms could start moving and cause
an injury if you leave the windscreen wipers
switched on. Remove the key from the ignition lock before
replacing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
To remove X
Remove the key from the ignition lock or
turn the key to position 0(KEYLESS GO).
X Fold the wiper arm away from the wind-
screen until it engages.
X Set the wiper blade at right angles to the
wiper arm. X
Remove the wiper blade from the retainer
on the wiper arm in the direction of the
arrow.
Fitting !
The two wiper blades are different
lengths. If you swap the wiper blades they
may scratch the windscreen. Make sure
that the longer wiper blade is fitted on the
driver's side.
X Compare the lengths of the two new wiper
blades.
X Slide the longer of the two new wiper
blades into the retainer on the wiper arm
on the driver's side in the opposite direc-
tion to the arrow.
X Repeat the same procedure on the front-
passenger's side with the shorter of the two
new wiper blades. 308

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 Get out of the vehicle.
X Close the driver’s door.
X Place the warning triangle (Y page 248) at
a suitable distance. Observe legal require-
ments. 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 cases your safety is especially
endangered, as tyre sealant is insufficient if:
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 systems must be carried out
at a qualified specialist workshop.
X Do not remove any foreign objects which
have penetrated the tyre, e.g. screws or
nails.
X Remove the TIREFIT kit, the accompanying
"max. 80 km/h" sticker and the electric air
pump from the stowage well underneath the boot/luggage compartment floor
(Y
page 249). X
Affix part :of the sticker within the driv-
er's field of vision.
X Affix part ;of the sticker near the valve
on the wheel with the defective tyre. G
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 thoroughly
with clean water.
R Change out of clothing which has come into
contact with TIREFIT immediately.
R If an allergic reaction occurs, consult a doc-
tor immediately.
Keep TIREFIT away from children.
R If TIREFIT is swallowed, immediately rinse
your mouth out thoroughly 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. 310

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-
