WARNING LIGHTS AND MESSAGES
IMPORTANT The warning light switches on in the instrument panel together with a dedicated message and/or acoustic signal when
applicable. These indications are indicative and precautionary and as such must not be considered as exhaustive and/or alternative to
the information contained in the Owner Handbook, which you are advised to read carefully in all cases. Always refer to the information
in this section in the event of a failure indication.
IMPORTANT Failure indications displayed are divided into two categories: very serious and less serious failures. Serious faults are
indicated by a repeated and prolonged warning “cycle”. Less serious faults are indicated by a warning “cycle” with a shorter duration.
The display cycle of both categories can be interrupted. The instrument panel warning light will stay on until the cause of the
malfunction is eliminated.
