Manual test in the central colour screen associated with the satellite navigation system
This function allows you to check the status of the vehicle systems (reminder of the "activated"/"deactivated" status of the configurable functions) and
to display the alerts log.
With the engine running, to start a manual
test, briefly press the ".../000" button on
the instrument panel.
The following information appears successively
in the instrument panel central colour screen:
- engine oil level indicator
(see corresponding section),
- service indicator (see corresponding
section),
- under-inflation detection (if your vehicle
is fitted with this system; see the "Safety"
section),
- current warnings and alert messages, if
any (see corresponding section for the
warning lamp or system concerned),
- status of configurable functions
(see "Multifunction screens").
Monitoring
This information also appears every
time the ignition is switched on
(automatic test).
