9. While the sealant bottle drains (approx. 30 seconds) the pressure
indicator on the comp ressor briefly points
to 6 bar. Pressure then sinks again. 10. All of the sealant is
pumped into the tyre.
Afterwards, the tyre is filled with air.
11. The prescribed tyre pressure 3264,
should be attained within 10 minutes.
Once the pressure is attained, switch off
the compressor by pressing button <
again.
If the prescribed tyre pressure is not
obtained within 10 minutes, remove the
tyre repair kit. Move the vehicle one tyre

(after 10 minutes at the latest), stop
and check the tyre pressure. To do this,
screw an air tube directly to the tyre
valve and compressor.
If tyre pressure is more than 1.3 bar,
adjust to the prescribed value. Repeat
the procedure until there is no more
pressure loss.
If the tyre pressure has dropped
below 1.3 bar, the vehicle must not
be used. Contact a workshop for
assistance.
17. Stow the tyre repair kit behind the cover on the right in the side trim in the
luggage compartment. To close, lower

or heats up greatly, switch it off for at
least 30 minutes.
The integrated safety valve opens at a
pressure of 7 bar.
Protect the compressor from moisture and
rain.
The sealant can only be stored for
approx. 4 years. After this time, the sealing
properties can no longer be guaranteed.
Heed the expiration
date on the sealant
bottle.

behind a cover.
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognised by its
melted wire. Do not replace the fuse until
the cause of the fault has been remedied.
Only fit fuses of the specified current
rating. Each fuse has its current rating
written on it, the ratings are also colour
coded.
