Lighting is associated
with the display of an-
other warning lamp :
Service If this comes on, it in-
dicates the occurrence
of a problem in one
of the systems which
does not have a specifi c warning
lamp.
In order to identify it, consult the mes-
sage on the multifunction screen.
The warning lamp only comes on
temporarily in the case of the follow-
ing minor faults:
- incorrect closing of the doors, boot, rear screen and bonnet,
- fl at remote control battery,
- incorrect tyre pressure,
- the end of saturation of the parti- cle emission fi lter (Diesel).
In the case of major faults, the warning lamp remains on until the operating
fault is rectifi ed, contact a CITROËN
dealer as soon as possible. Braking
If this comes on, it indicates
the occurrence of a fault in
one of the braking systems:
- signifi cant drop in the level in the circuit,
- electronic brake force distribution (EBFD) faulty (simultaneous light-
ing of the ABS warning lamp),
stop the vehicle immediately and as
safely as possible.
Consult a CITROËN dealer.
Application/Release of the
automatic electric parking brake
If this warning lamp comes
on permanently, it is confi rm-
ing that the parking brake is
applied.
If it fl ashes, it is indicating an ap-
plication or release fault. Contact
a CITROËN dealer urgently (see
section "Driving - § Electric parking
brake"). Automatic electric parking brake
fault
This warning lamp comes
on if there is a malfunction in
the automatic electric park-
ing brake.
Deactivation of the automatic
functions of the automatic
electric parking brake
This comes on if the "auto-
matic application" and "auto-
matic release" functions
when you switch off the
engine are deactivated * or
faulty.
Dynamic stability control
(ESP/ASR) The ESP/ASR system is put
into service automatically
when the vehicle is started.
Unless the system has been
deactivated, if this warning lamp
and the indicator lamp on the button
come on continuously, this indicates
the occurrence of a fault in the ESP/
ASR system or in the hill start assist
system.
Engine autodiagnostics system
If this comes on, it indicates
the occurrence of a fault in
the engine management
system.
If it fl ashes, it indicates the oc-
currence of a fault in the emission
control system.
Central alert
- punctured wheel,
- braking,
- coolant temperature,
stop the vehicle immediately and as
safely as possible.
Consult a CITROËN dealer.
Anti-lock braking system (ABS) If this comes on, it indicates
the occurrence of a fault in
the anti-lock braking system.
However, this does not
prevent operation of the vehicle's
assisted braking.

I N S T R U M E N T S a n d C O N T R O L S Airbags If this comes on, it indicates
the occurrence of a fault in
one of the airbag or seat belt
pretensioner systems.
Maximum coolant temperature
If this comes on, it indicates
that the temperature in the
cooling system is too high.
Stop the vehicle as soon as
it is safe to do so.
Low fuel level When the tank is full, all the
bars are lit up.
If the fuel low warning lamp
comes on accompanied by
an audible signal and a message on
the multifunction screen, there are
approximately 7 litres of fuel remain-
ing in the tank and 2 or 3 bars fl ash
in the instrument panel.
When the last bar goes out, there
are approximately 2 litres of fuel re-
maining in the tank.
Top up with fuel as soon as possible
to avoid running out.
This warning lamp comes on each
time the ignition is switched on, until
suffi cient fuel is added.
A control located on the panel to the
left of the steering wheel allows you
to open the fuel fl ap from inside the
vehicle.
Do not continue driving until you run
out of fuel as this may cause dam-
age to the emisions control and fuel
injection systems. Battery charge
If this comes on, it indi-
cates the occurrence of a
fault in the battery charging
circuit (dirty or loose termi-
nals, slack or cut alternator
belt, ...).
Door open A door, the boot or the rear
screen is open:
- if the speed is below 6 mph (10 km/h), this warning lamp comes on continuously,
- if the speed is higher than 6 mph (10 km/h), this warning lamp comes on
continuously, accompanied by an audi-
ble signal.
Seat belt not fastened/
unfastened
This warning lamp informs
you if the driver’s or front
passenger’s seat belt is
not fastened (depending
on model), and if the front
passenger’s (depending on
model) or the second row
passengers’ seat belts are
unfastened. The lit up positions repre-
sent those whose seat belts are not
fastened/unfastened. Seat belts unfastened during the
journey:
- the point corresponding to the
seat position with seat belt un-
fastened lights up between 0 and
approximately12 mph (20 km/h).
Above 12 mph (20 km/h), it fl ash-
es accompanied by an audible
signal for around 120 seconds.
The audible signal stops when
the ignition is switched off or if a
door is opened.
Depending on model, the front pas-
senger seat may be fi tted with a
presence sensor; the correspond-
ing warning lamp will only come on
if the seat is occupied and the seat
belt not fastened.
Driver’s or front passenger’s seat belt
not fastened with presence sensor:
- the warning lamp lights up be-
tween 0 and approximately
12 mph (20 km/h). Above 12 mph
(20 km/h), it fl ashes accompa-
nied by a message on the mul-
tifunction screen and an audible
signal for around 120 seconds.
Second row rear passengers’ or
front passenger’s seat belt not fas-
tened without presence sensor:
- when the ignition is switched on, the points corresponding to the seat po-
sitions with seat belts not fastened
remain lit up for 30 seconds.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer.
Take care when working under the
bonnet, as some parts of the engine
can be extremely hot (risk of burns).
Oil level
Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. Oil specifi cation The oil must correspond to your en-gine and conform to the manufacturer's
recommendations.
Brake fluid level
Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This fl uid must be changed regu-
larly. Fluid which has been used for
too long may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and fulfi l the DOT4 standards.
Coolant level
Coolant change
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Check this level also between each
scheduled service and before long
journeys. The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm,
the temperature of the coolant is regu-
lated by the fan. This can operate with
the ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the en-
gine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour
after switching off the engine before
carrying out any work.
To avoid any risk of scalding, un-
screw the cap by two turns to allow
the pressure to drop. When the pres-
sure has dropped, remove the cap
and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.
