Maintenance indicator
System which informs the driver
when the next service is due, in
accordance with the manufacturer's
servicing schedule.
The point at which the service is due
is calculated from the last indicator
zero reset. It is determined by two
parameters:
- the distance travelled,
- the time elapsed since the last service. 5 seconds after the ignition is switched
on,
the spanner is switched off ; the
distance recorder resumes its normal
operation. The display then indicates
the total and trip distances.
Less than 620 miles (1 000 km)
remain before the next service
is due

Example: 560 miles (900 km) re-
main before the next service is due.
For 5 seconds after the ignition is
switched on, the display indicates: Service overdue
For 5 seconds after the ignition is
switched on,
the spanner fl ashes
to indicate that the service must be
carried out as soon as possible.

Example: the service is overdue by
300 miles/km.
For 5 seconds after the ignition is
switched on, the display indicates:
5 seconds after the ignition is
switched on, the distance recorder
resumes its normal operation. The
spanner remains on to indicate that
a service must be carried out soon. 5 seconds after the ignition is
switched on, the distance recorder
resumes its normal operation.
The
spanner remains lit .
More than 620 miles (1 000 km)
remain before the next service
is due
For 5 seconds after the ignition is
switched on, the spanner symbo-
lising the service operations comes
on. The distance recorder display
line indicates the distance remaining
before the next service is due.

Example: 4 800 miles/km remain
before the next service is due.
For 5 seconds after the ignition is
switched on, the display indicates:
The distance remaining may be
weighted by the time factor, depen-
ding on the driver's driving habits.
Therefore, the spanner may also
come on if you have exceeded the
two year service interval.

Air conditioning
To ensure that your system operates
correctly, it is recommended to have
it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If after a lengthy stop in bright sunlight
the interior temperature is excessive,
air the passenger compartment by
opening the windows for a few mo-
ments, then close them again.
The air conditioning operates by using
power from the engine. This results in
a slight increase in fuel consumption.
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's servic-
ing schedule (see "Maintenance and
Warranty Guide").
Air circulation
Air vents on the fl oor underneath the
front seats provide enhanced heat-
ing for the rear seat positions; take
care not to obstruct them.
Air vents
The air vents to the face have grilles
and thumbwheels to adjust the air
fl ow and direction (up-down, right-
left).
The automatic regulation of the air
conditioning, inside the cabin, uses
a number of sensors (sunlight sen-
sor, outside temperature sensor...)
that relieve you of the need to make
frequent adjustments outside the
displayed temperature.
Be careful not to obstruct the sun-
light sensor, located on the dash-
board behind the instrument panel.

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.
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 manufactur-
er'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
Draining the system
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, 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.
