Inflate tyres
This information only serves as information for
the prescribed tyre pressure. This is not a listing
of approved tyre sizes for your vehicle. These
are in the vehicle's technical documentation, as
well as in the declaration of conformity (in the
so-called COC document).
Fit the tyre inflation hose of the air compressor to
the tyre valve.
›
Secure the vehicle with the parking brake.
Start the engine.
Plug the connector into the 12 volt socket .
Turn on the air compressor.
Once a tyre pressure of 2.0-2.5 bar is reached, turn
off the air compressor.

Tyre pressure monitor
Functionality
If an air pressure of 2.0 - 2.5 bar has not been
reached, remove the tyre inflation hose from the
valve.
›
The tyre pressure monitoring indicator indicates a
change in tyre pressure.
Drive approx. 10 metres forwards or backwards to
allow the sealing agent to distribute in the tyre.
›
Replace the tire inflation hose on the valve and re-
peat the inflation procedure.

Always adjust the tyre pressure to the load.
Check the pressure in all tyres at least once a
month and before each longer ride.

Check the pressure when the tyres are cold. Do
not reduce the higher pressure of warm tyres.
After each change in tyre pressure, save the new
values in the tyre control display.

WARNING
Risk of an accident!
If tyre pressure loss is very quick, try to stop the
vehicle carefully without heavy steering or heavy
braking.
The system is unable to provide a warning in the
event of a very rapid tyre pressure loss, e.g. sudden
puncture.
▶
The system function may be restricted in the follow-
ing cases:
Uneven loading of the wheels, e.g. with a trailer at-
