If and when

Note

• Do not use the compressor for longer than 6 minutes. Otherwise, it might

overheat. When the compressor has cooled down, you can use it again.

• If tyre sealant should leak out, leave it to dry and then pull it off like foil.

• After carrying out a tyre repair remember to buy a new tyre sealant can at

a qualified workshop. This will ensure that the Tyre Mobility System is opera-

tive again.

• Please observe legal requirements when doing so.

Changing fuses

-

Remove the fuse cover using a screwdriver ⇒ fig. 202.

If a fuse has blown, it must be replaced.

–

Identify the fuse for the failed component ⇒ page 263, “Fuse

assignment”.

-

Take the plastic clip from inside the fuse cover, fit it onto the

blown fuse, and pull the fuse out.

-

Replace the blown fuse (which will have a melted metal strip)

with a new fuse of the same amp rating.

-

Fit the fuse cover back on.

The individual electrical circuits are protected by fuses. The fuses are located

behind a cover at the left-hand end of the instrument panel.
