The brake fluid level is too low. Top up using a brake fluid listed by
CITROËN.If the problem persists, contact
a CITROËN dealer or a qualified
workshop.
Fault with the braking system. You must stop as soon as it is safe to do so.Have the system checked by a
CITROËN dealer or a qualified
workshop.
Fault with the anti-lock braking
system (ABS). Contact a CITROËN dealer or a
qualified workshop.The vehicle retains conventional
braking without assistance but you
are advised to stop.
The tyre pressure is too low in one
or more tyres. Check the tyre pressures as soon
as possible.
This check should preferably
be done with the tyres cold.
You must reinitialise the system
after adjusting one or more tyre
pressures or after changing one or
more wheels.
For more information, refer to the
"Under-inflation detection system"
section.If the problem persists, contact
a C
ITR
oËn d

ealer or a qualified
workshop.
There is a fault with the under-
inflation detection system and/or
at least one wheel does not have a
detected sensor. The tyre pressures are no longer
monitored.
Have the system checked by a
CITROËN dealer or a qualified
workshop.

Under-inflation alert
The alert is given by the fixed
illumination of this warning lamp and
the display of a message.

educe speed, avoid sudden steering
movements or harsh brake applications.

S

top as soon as it is safe to do so. The loss of pressure detected does not
always lead to visible deformation of the
tyre. Do not rely on just a visual check. The alert is maintained until the
reference pressure is reinitialised after
the inflation, repair or replacement of
the tyres concerned. In the event of
the repair or replacement of tyres, the
sensor identifiers must be registered in
the system by a CITROËN dealer or a
qualified workshop.
The spare wheel does not have
a sensor, so there is no need to
reinitialise the the system for running
with the spare wheel fitted.
F
I f you have a compressor (the one in the
temporary puncture repair kit for example),
check the four tyre pressures when cold.
I

f it is not possible to check the tyre
pressures at the time, drive carefully at
reduced speed.


or
F

I
n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (according to equipment).
Reinitialising the reference
pressure
Before reinitialising the system, ensure
that the pressures in the four tyres are
suitable for the conditions of use of the
vehicle and as specified on the tyre
pressure label.
The under-inflation detection system
cannot warn of an incorrect pressure at
the time of reinitialisation.
The system must be reinitialised after any
adjustment of tyre pressures and after
changing one or more wheels.
