Driver
IN AN EMERGENCY
If the driver is the only occupant and their seat belt is not fastened,
when 20 km/h is exceeded or when travelling at a speed between 10
and 20 km/h for longer than 5 seconds, an acoustic signal cycle
will be started for the front seats (continuous acoustic signal for
6 seconds followed by a 90 second beep). The warning light will flash.
SERVICING AND
MAINTENANCE
The warning lights will stay on constantly at the end of the cycle until
the engine is stopped. The acoustic signal will be interrupted
immediately when the driver's seat belt is fastened and the warning
light will turn green.
TECHNICAL
The reminder cycle (acoustic and visual) will be repeated as described
SPECIFICATIONS
above and the red warning light will flash if the seat belt is unfastened
again while travelling.

Passenger
A similar situation applies to the front passenger, with the difference
that the warning light turns green and the indication is also interrupted
when the passenger leaves the car.
If both front seat belts are unfastened a few seconds apart while the
car is travelling, the acoustic signal will refer to the most recent event
and the two warning lights will proceed with the visual indication
independently.
Rear seats (warning light no. 2, no.
3 and no. 4)
For the rear seats, the reminder cycle is only activated when any seat
belt is unfastened (flashing red).
In this condition, the warning light for the seat belt which has been
unfastened will flash (red) for approximately 30 seconds. An acoustic
signal is also emitted.
The visual indication (flashing red) will start and stop independently for
each warning light if several seat belts are unfastened. The warning
light will become green when the relevant seat belt is fastened again.
The rear seat warning lights will switch off, regardless of the state
of the belt (red or green) approximately 30 seconds after the last
signal.
IMPORTANT
The warning lights are all off if all seat belts (front and rear) are
already fastened when the ignition key is turned to MAR.
All warning lights switch on when at least one belt changes from
fastened to unfastened or vice versa.
