Instruments  
Persistent warning lamp  
Warning and indicator  
lamps  
Displayed as symbols, visual indicators  
which 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.  
1
When the engine is running or the vehicle is  
being driven, the illumination of a red or orange  
warning lamp indicates a fault that needs  
further investigation, using any associated  
message and the description of the warning  
lamp in the documentation.  
Where 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.  
Associated warnings  
The illumination of a lamp can 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 a fault has occurred:  
refer to the description of each lamp for further  
information.  
(1): You must stop as soon as it is safe to do  
so and switch off the ignition.  
(2): Contact a CITROËN dealer or a qualified  
workshop.  
(3): Go to a CITROËN dealer or a qualified  
workshop.  
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 equipment or  
a function, refer to the corresponding section.
