Warning and indicator 
lamps
Displayed as symbols, the warning and indicator 
lamps inform the driver of the occurrence of a 
malfunction (warning lamps) or of the operating 
status of a system (operation or deactivation 
indicator lamps). Certain lamps light up in two 
ways (fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied 
by an audible signal and/or a message displayed 
in a screen.
Relating the type of alert to the operating status 
of the vehicle allows you to determine whether 
the situation is normal or whether a fault has 
occurred: refer to the description of each lamp 
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on 
for a few seconds when the ignition is switched 
on. These warning lamps should go off as soon 
as the engine is started.
For more information on a system or a function, 
refer to the corresponding section.
Warning lamp continuously 
lit
The illumination of a red or orange warning lamp 
indicates the occurrence of a fault that needs 
further investigation.
If a warning lamp remains lit
The references (1), (2) and (3) in the warning 
and indicator lamp description indicate whether 
you should contact a qualified professional in 
addition to the immediate recommended actions.
(1): You must stop the vehicle .
Stop as soon as it is safe to do so and switch off 
the ignition.
