For effective use of the system, we recommend:
- Automatic air conditioning
With the automatic air conditioning, use of the AUTO function is recommended.

I N S T R U M E N T S a n d C O N T R O L S 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.
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 are lit.
When the last bar goes out, there
are approximately 2 litres of fuel re-
maining in the tank.
Lighting is associated
with the lighting of an-
other warning lamp:
Service If this comes on, it indi-
cates the occurrence
of a problem in one
of the systems which
does not have a spe-
c i fi c w a r n i n g l a m p .
It is accompanied by a message on
the multifunction screen.
The warning lamp comes on tempo-
rarily in the case of minor faults.
In the case of major faults, the
warning lamp remains on until the
o p e r a t i n g f a u l t i s r e c t i fi e d . C o n t a c t
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:
- s i g n i fi c a n t d r o p i n t h e fl u i d l e v e l in the circuit,
- electronic brake force distribu- tion (EBFD) faulty (simultane-
ous lighting of the ABS warning
lamp),
stop the vehicle as soon as it is safe
to do so.
Contact a CITROËN dealer.
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 as-
sistance. Engine autodiagnostics system
If this comes on, it indicates
the occurrence of a fault in
the engine management
system.
I f i t fl a s h e s , i t i n d i c a t e s t h e o c c u r -
rence of a fault in the emission con-
trol system.
Central alert
- punctured wheel,
- braking,
- coolant temperature,
stop the vehicle as soon as it is safe
to do so.
Contact 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 servo-assist-
ed braking system.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.

Oil level
Draining the engine
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. O i l s p e c i fi c a t i o n
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 Maintenance and
Warranty Guide for details of the in-
terval for this operation.

too long may cause a loss of braking

Coolant level
Draining the circuit
The coolant does not have to be
changed.
F l u i d s p e c i fi c a t i o n
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. T h e b r a k e fl u i d l e v e l s h o u l d
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.

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 al-
low 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.
