Important safety notes G
WARNING
Certain components in the engine compart-
ment coul dbevery hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is arisk of injury when accessing the
engine compartment.
As far as possible ,allow the engine to cool
dow nand only touch the components descri-
bed in the following. G
WARNING
The cooling system is pressurised, particu-
larl yw hen the engine is warm. If you open the
cap, you coul dbescalded if hot coolant
sprays out. There is arisk of injury. Let the engine cool dow
nbefore you open the
cap. Wea rglove sand eye protection. Open
the cap slowly to release the pressure. G
WARNING
If windscreen washer concentrate comes into contact with hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure the windscreen washer concen-
trate does not come into contact with the filler neck.
Checking the coolan tlevel X

Engine compartmentMaintenance and care

If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from yours kin
immediately with water.
R If the tyre sealant comes into contact with
youre yes,immediately rinse them thor-
oughlyw ith clean water.
R If tyre sealant is swallowed, immediately
rinse yourm outh out thoroughl yand drink
plenty of water. Do not induce vomiting,
and seek medica lattention 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 ten minutes at atime with-
out abreak. It may otherwise overheat.
The tyre inflation compressor can be oper-
ated again once it has cooled down.
Complyw ith the manufacturer's safety instruc-
tions on the sticker on the tyre inflation com-
pressor.
Usingt he TIREFITk it X
Do not remove any foreign objects which have
penetrated the tyre, e.g. screws or nails.
X Remove the tyre sealant bottle, the accom-
panying TIREFIT sticker and the tyre inflation
compressor from the stowage space under
the boot floor (Y page 336). X
Affix part :of the TIREFIT sticker to the
instrument cluster within the driver's field of
vision.
X Affix part ;of the TIREFIT sticker near the
valve on the wheel with the defective tyre. X

X Turn the key to position 1in the ignition lock
(Y page 145).
X Press on and off switch ?on the tyre inflation
compressor to ON.
The tyre inflation compressor is switched on.
The tyre is inflated.
First, tyre sealant is pumped into the tyre. The pressure may briefly rise to approximately
500 kPa (5 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 ten minutes. The tyre should
then have attained apressure of at least
200 kPa (2.0 bar/29 psi).
If ap ressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten minutes, see "Tyre pres- sure reached" (Y page 340).
If at yre pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten minutes, see "Tyre
pressure not reached" (Y page 340).
If tyre sealant leaks out, make sure you clean the
affected area as quickly as possible.Itisp ref-
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
at yre pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre.
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 amaximum of ten minutes, the tyre
pressure must be at least 200 kPa (2.0 bar/
29 psi). G
WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged.T he tyre sealant cannot repair the tyre in this instance. Damaged tyres and
atyre
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
Tyre pressure reached G
WARNING
At yre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitablef or higher speeds. There is arisk of
accident.
You should therefore adapty our driving style
accordingly and drive carefully.Don ot exceed
the specified maximum speed with atyre that
has been repaired using tyre sealant.
The maximum permissibles peed foratyre
sealed with tyre sealant is 80 km/h. The upper
part of the TIREFIT sticker must be affixed to the
instrument cluster where it will be easilys een 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. ataqualified specialist
workshop.
If at yre pressure of 200 kPa (2.0 bar/29 psi) has
been attained 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). 340

WARNING
Ad ischarged battery can freeze at tempera-
tures below freezin gpoint. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is arisk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with
amaximum
charging voltage of 14.8 V.
All vehicles:
! Only charge the battery using the jump-start
connection point.
The jump-starting connection point is in the
engine compartment (Y page 345).
X Open the bonnet.
X Connect the battery charger to the positive
terminal and earth point in the same order as
when connectingt he donor battery in the
jump-starting procedure (Y page 345).
Keep away from fire and naked flames. Do not
lean over the battery. Never charge the battery
if it is still fitted to the vehicle, unless you use a battery charger which has been tested and
approved by Mercedes-Benz. Abattery charger
unit specially adapted for Mercedes-Benz vehi-
cles and tested and approved by Mercedes-
Benz is available as an accessory. This device
permits charging of the battery in position. Con-
tact aMercedes-Benz Service Centre for infor-
mation and availability. Read the battery charg-
er's operating instructions before charging the
battery.
All vehicles except vehicles with alithium-
ion battery: if the indicator/warning lamps in
the instrument cluster do not light up at low
temperatures, it is very likely that the dis-
charged battery has frozen .Inthis case you may
neither jump-start the vehicle nor charge the
battery. The service life of abattery that has
been thawed may be reduced. The starting char-
acteristics may be impaired, especially at low
temperatures. Have the thawed battery
checked at aqualified specialist workshop. Vehicles with
alithium-ion battery: at low
temperatures, do not charge abattery which has
been removed using abattery charger. Allow the
battery to warm up gently first, if necessary.
Otherwise, the service life can be shortened and the starting characteristics impaired, especially
at low temperatures. 344
