ing 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 fl uid level in the circuit,
- electronic brake force distribu- tion (EBFD) faulty (simultane-
ous lighting of the ABS warning
lamp),
stop the vehicle immediately and as
safely as possible.
Consult a CITROËN dealer.
Parking brake
When stationary, the perma-
nent lighting of this warning
lamp confi rms that the par-
king brake is applied.

Maintenance indicator zero reset
After each service, the maintenance
indicator must be reset to zero.
Your CITROËN technician resets the
indicator to zero after each service.
However, if you do your own servi-
cing, the procedure for resetting to
zero is as follows:

 switch off the ignition,

 press and hold the trip distance
recorder zero reset button,

 switch on the ignition; the dis-
tance recorder display begins a
countdown,

 when the display indicates "=0" ,
release the button; the spanner
disappears.
Following this operation, if you wish
to disconnect the battery, lock the
vehicle and wait at least fi ve minutes
for the zero reset to be taken into ac-
count. Engine oil level indicator
System which informs the driver
whether the engine oil level is cor-
rect or not.
This information is indicated for a
few seconds when the ignition is
switched on, after the service infor-
mation.
The level read will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 15 minutes.
Oil level correct
Oil level low
This is indicated by displaying of the
message "Oil level incorrect".
If the low oil level is confi rmed by a
check using the dipstick, it is essen-
tial that the level is topped up to pre-
vent damage to the engine. Oil level gauge fault
This is indicated by displaying of
the message "Oil level measure-
ment invalid". Consult a CITROËN
dealer.

Engine oil temperature gauge
Under normal operating conditions,
the bars should be within section 1 .
In severe operating conditions, the
bars may extend into section 2 .
In this event, slow down, and if neces-
sary, stop the engine and check the
levels (see corresponding chapter). Coolant temperature
indicator
Under normal operating conditions,
the bars should be within section
1 .
In severe operating conditions, the
bars may extend into section 2 , the

lamp A and the STOP warning lamp
will light up, stop immediately . Switch
off the ignition. The cooling fan may
continue to operate for a certain
time .
Consult a CITROËN dealer.
If the SERVICE warning lamp lights

Air conditioning
We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following func-
tions: air fl ow, temperature in the
passenger compartment and air
distribution, by means of various
sensors (exterior temperature, sun-
shine). This eliminates any need for
you to change your settings other
than the temperature value dis-
played.

 Please do not block the sunshine
sensor A .
If you select the automatic mode (by
pressing the "AUTO" control) and
leave all of the vents open, optimum
comfort will be maintained and humid-
ity and condensation will be removed
regardless of the exterior climatic con-
ditions.
The temperature in the passenger
compartment can only be lower than
the exterior temperature if the air
conditioning is on.
VENTILATION, HEATING AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air condi-
tioning must be used with the windows
closed. If the vehicle has been parked
in the sun for a long period and the in-
terior temperature is very high, venti-
late the passenger compartment with
the windows open for a few minutes,
then close the windows.
To keep the air conditioning system
in good working order it is essential
that it is operated at least once a
month.
The air conditioning uses the engine
power during its operation. As a result,
the fuel consumption of the vehicle in-
creases.
In certain cases of particularly ardu-
ous use (e.g. towing the maximum
load on a steep gradient in high tem-
peratures), switching off the air condi-
tioning permits the recovery of engine
power and therefore increases the
towing capacity.
Air inlet
Check that the exterior grille for the
air inlet, at the bottom of the wind-
screen, is clean and free of dead
leaves, snow, etc.
When washing the vehicle using a
high pressure nozzle, avoid spray-
ing at the air inlet. Air circulation
Maximum comfort is obtained by
means of a good distribution of air in
the passenger compartment, both in
the front and in the rear.
To obtain a uniform distribution of
air, take care not to block the ex-
terior air intake grille located at the
base of the windscreen, the vents,
the air outlets under the front seats
and the air extractor located behind
the fl aps in the boot.
The front and rear vents are fi tted
with thumbwheels to adjust the air
fl ow and direction. We recommend
that you leave all of the vents open.
Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter has to be changed in ac-
cordance with the vehicle mainte-
nance schedule (see: "Maintenance
and Warranty Guide").
