the tire pressure on the gauge when
the compressor is off, in order to have
a more precise reading.

for more than 20 minutes: risk of
overheating! The compressor has been
designed for inflating the spare wheel

WARNING: Power is supplied to the
current plug only when the key is
turned to MAR and it can only be
connected to devices with a power
absorption of 15A maximum (180W
power). Do not connect devices with a
higher power absorption to the
current plug. A prolonged power
absorption can discharge the battery,
preventing the engine from being
started once again.
