256 Vehicle care
10. Set the rocker switch on the
compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge
briefly indicates up to 6 bar whilst
the sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into
the tyre. Then the tyre is inflated.
13. The prescribed tyre pressure
should be obtained within
10 minutes.
Tyre pressure 3 283.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
10 minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button over the pressure
indicator.
Depending on version the button
can be located on the air hose.
Do not run the compressor longer
than 10 minutes.
14. Detach the tyre repair kit. Push
catch on bracket to remove
sealant bottle from bracket. Screw
the tyre inflation hose to the free
connection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
15. Remove any excess sealant
using a cloth.
