Warning and indicator 
lamps
Associated warnings
The illumination of a lamp can be accompanied 
b y 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.
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.
Persistent warning lamp
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.
(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.
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.
