X Solutions The coolant tempera-
ture gauge shows a
value above 120 †.
The coolant warning
lamp may also light up
and a warning tone may

notes as you do so and top up the coolant if necessary. If the coolant level is correct, the radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.

If the coolant temperature is less than 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving on

X
Remove the cap from valve Eon the faulty
tyre. X
Make sure pressure release screw Fon
pressure gauge Gis fully closed.
X Screw filler hose Donto valve E.
X Insert plug Ainto the socket of the ciga-
rette lighter* (Y page 282) or into a 12 V
power socket in your vehicle (Y page 282).
X Turn the key to position 2(Y page 182) in
the ignition lock.
X Press on/off switch ?on the electric air
pump to I.
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 eight minutes at a time without
a break. It may otherwise 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 air
pump and drive the vehicle forwards or
backwards approximately 10 m.
This distributes the TIREFIT more evenly.
X Pump up the tyre again. G
Risk of accident
If a pressure of 1.8 bar is not achieved after
five minutes, the tyre is too badly 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.
When a tyre pressure of at least 1.8 bar
is reached:
X Press on/off switch ?on the electric air
pump to 0.
The electric air pump is switched off.
X Remove the TIREFIT kit 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 in which the TIREFIT kit was contained.
X Stow away the TIREFIT kit, the electric air
pump and the warning triangle.
X Pull away immediately.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the electric air pump. Flat tyre
