Lighting is associated
with the displaying of
another warning light:
Service
If this comes on, it indi-
cates the occurrence of a
problem in one of the sys-
tems which does not have
a specifi c warning light.
In order to identify it, consult the message
on the multifunction display.
The warning light 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 particle emission fi lter (Diesel).
In the case of major faults, the warn-
ing light 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 distribu- tion (EBFD) faulty (simultane-
ous lighting of the ABS warning
light),
stop the vehicle immediately and as
safely as possible.
Consult a CITROËN dealer.
Application/Release of the
automatic electronic 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. Urgently
contact a CITROËN dealer (see sec-
tion "Driving - § Electronic parking
brake"). Automatic electronic parking
brake fault
This warning lamp comes
on if there is a malfunction
in the automatic electronic
parking brake.
Deactivation of the automatic
functions of the automatic
electronic parking brake
This comes on if the "auto-
matic application" and "au-
tomatic 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 light
and the indicator light on the button
come on continuously, this indicates
the occurrence of a fault in the ESP/
ASR system or in the hill start as-
sistance.
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 occurrence 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 op-
eration of the vehicle's assisted
braking.

I
I N S T R U M E N T S a n d C O N T R O L S Air bags If this comes on, it indicates
the occurrence of a fault in
one of the air bag 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 immediately
and as safely as possible.
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
remaining 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.
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.
Battery charge If this comes on, it indicates
the occurrence of a fault in
the battery charging circuit
(dirty or loose terminals, 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 light
comes on continuously.
- if the speed is higher than 6 mph (10 km/h), this warning
light comes on continuously, ac-
companied by an audible 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 rep-
resent 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
20 km/h. Above 20 km/h (approx.
12 mph), it fl ashes accompanied
by a sound signal for around
120 seconds. The sound sig-
nal 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 between
0 and 20 km/h. Above 20 km/h
(approx.12mph), it fl ashes accom-
panied by a message on the multi-
function screen and a sound signal
for around 120 seconds.
Rear passengers’ or front passen-
ger’s seat belt not fastened 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 circuit checked by a
CITROËN dealer.
Oil level
Draining the engine
Refer to the servicing booklet for de-
tails of the interval for this operation. Oil specifi cation
The oil must correspond to your en-
gine and conform to the manufactur-
er's recommendations.
Brake fluid level
Draining the circuit
Refer to the servicing booklet for de-
tails of the interval for this operation.
This fl uid must be changed regularly.
Fluid which has been used exces-
sively 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
Draining the circuit
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.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (approx. 1 000 km).
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
regulated by the fan. This can oper-
ate 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,
unscrew the cap by two turns to
allow the pressure to drop. When
the pressure 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.
