Instruments

Indicator and warning lamps

Visual indicators informing the driver that a system is in operation or is switched off (indicator lamp),

or has a fault (warning lamp).

When the ignition is switched on

Warning lamps

Operation indicator lamps

Certain warning lamps come on for a few

seconds when the vehicle's ignition is

switched on.

When the engine is started, these same

warning lamps should go off.

When the engine is running or the vehicle is

being driven, illumination of one of the following

warning lamps indicates a fault which requires

action on the part of the driver.

Any fault resulting in the illumination of a

warning lamp must be investigated further

using the associated message.

If one of the following indicator lamps comes on

in the instrument panel and/or instrument panel

screen, this confirms that the corresponding

system has come into operation.

If they remain on, before moving off, refer to the

information on the warning lamp concerned.

If you encounter any problems, contact a

CITROËN dealer or a qualified workshop.

Associated warnings

Certain warning lamps may come on in one of

two modes: fixed (continuous) or flashing.

Only by relating the type of illumination to the

operation of the vehicle can it be determined

whether the situation is normal or a fault has

occurred. In the event of a fault, the illumination

of the warning lamp may be accompanied by

an audible signal and/or a message.

Deactivation indicator lamps

If one of the following indicator lamps comes

on, this confirms that the corresponding system

has been switched off intentionally.

This is may be accompanied by an audible

signal and the display of a message.
