"Tyre pressure too low" message
This message indicates pressure loss of at least
0.3 bar (4 psi).
The message indicates the wheel in which the
pressure loss has been detected. The deviation
from the required pressure is displayed for the
corresponding wheel.
The message appears only when the vehicle is
stationary. It appears for the first time when the
ignition is switched off and then each time the
ignition is switched on until the tyre pressure has
been corrected to the required value.
The message is shown for 10 seconds on the
multi-purpose display. It can be suppressed
immediately by pressing the ENTER button.
f Check the tyre pressure at the next opportu-
nity and fill the tyres.
Example: If the tyre pressure display shows
"– 0.3 bar (–4 psi)", you must increase the tyre
pressure by 0.3 bar (4 psi).
The spare wheel and collapsible spare wheel are
not equipped with wheel transmitters and are not
monitored by Tyre Pressure Monitoring.
