MOBILITY
Let the compressor run for max. 10 minutes
to fill in the tire sealant and reach a tire
pressure of 2.5 bar/36 psi.
While the tire is being filled with tire sealant,
the tire pressure can briefly reach approx.
6 bar/87 psi. Do not turn off the compres-
sor in this phase.
2. Switch off the compressor.
Checking the tire pressure
Read the tire pressure on the tire pressure dis-
play of the compressor. The tire pressure must
be at least 2.5 bar/36 psi.
Tire pressure too high
If the tire pressure is too high, reduce the tire
pressure with the pressure reducing valve on
the compressor.
Minimum tire inflation pressure is not
reached
Do not continue driving unless a minimum tire
pressure of 2.5 bar/36 psi is reached. Contact
an authorized service center or another quali-
fied service center or repair shop.
Minimum tire inflation pressure is
reached
1. Pull the connector out of the socket in the
vehicle interior.

4. Stow the tire repair set in the cargo area.
5. Immediately drive 5 miles/10 km to ensure
that the tire sealant is evenly distributed in
the tire.
Do not exceed the permissible maximum
speed of 50 mph/80 km/h.
If possible, do not drive at speeds less than
12 mph/20 km/h.
Tire sealant may spray from the damaged
area during the initial wheel rotations.
Adjusting the tire pressure
1. Stop at a suitable location.
2. Connect the hose directly to the compres-
sor and turn clockwise by 90° until it audi-
bly engages.
3. Unscrew the valve cap from the wheel and
screw the connecting piece of the hose
onto the valve.
4. Insert the connector into the socket in the
vehicle interior.
5. Read the tire pressure on the tire pressure
display of the compressor.
