Engine oil level indicator

The vehicle must be on level
ground and the engine must
have been off for more than
30 minutes for this level check to
be accurate.
Oil level correct
This is indicated by the fl ashing of
"OIL"
or the display of a specifi c mes-
sage in the instrument panel, coupled
with the service warning lamp and ac-
companied by an audible signal.
If the low oil level is confi rmed by a
check using the dipstick, the level must
be topped up to avoid damage to the
engine.
Oil level indicator error

Dipstick
Refer to the "Checks" section to locate
the dipstick and the oil fi ller cap on your
engine.
Oil level incorrect This is indicated by the fl ashing of
"OIL --"
or the display of a specifi c mes-
sage in the instrument panel. Contact a
CITROËN or a qualifi ed workshop.
There are 2 marks on the
dipstick:


- A

this level (risk of dam-
age to the engine),

- B
= min; top up the level
via the oil fi ller cap, us-
ing the correct grade of
oil for your engine.

This information is displayed for a few
seconds when the ignition is switched

RECOMMENDATIONS FOR VENTILATION AND AIR
CONDITIONING
In order for these systems to be fully effective, follow the operation and
maintenance guidelines below:


)
To obtain an even air distribution, take care not to obstruct the exterior air
intake grilles located at the base of the windscreen, the nozzles, the vents
and the air outlets, as well as the air extractor located in the boot.

)
Do not cover the sunshine sensor, located on the dashboard; this is
used for regulation of the digital air conditioning system.

)
Operate the air conditioning system for at least 5 to 10 minutes, once or
twice a month to keep it in perfect working order.

)
Ensure that the passenger compartment fi lter is in good condition and
have the fi lter elements replaced regularly (refer to the "Checks" sec-
tion).
We recommend the use of a combined passenger compartment fi lter.
Thanks to its special active additive, it contributes to the purifi cation of
the air breathed by the occupants and the cleanliness of the passenger
compartment (reduction of allergic symptoms, bad odours and greasy
deposits).

)
To ensure correct operation of the air conditioning system, you are
also advised to have it checked regularly as recommended in the
Maintenance and Warranty Guide.

)
If the system does not produce cold air, switch it off and contact a
CITROËN dealer or a qualifi ed workshop.
When towing the maximum load on a steep gradient in high temperatures,
switching off the air conditioning increases the available engine power and
so improves the towing ability.
If after an extended stop in sun-
shine, the interior temperature is
very high, fi rst ventilate the pas-
senger compartment for a few
moments.
Put the air fl ow control at a set-
ting high enough to quickly
change the air in the passenger
compartment.
The air conditioning system
does not contain chlorine and
does not present any danger to
the ozone layer.

The condensation created by
the air conditioning results in a
discharge of water under the ve-
hicle which is perfectly normal.



Stop & Start
The heating and air conditioning systems only work when the engine is run-
ning. To maintain a comfortable temperature in the passenger compartment,
you can temporarily deactivate the Stop & Start system (see "Driving").

MANUAL AIR CONDITIONING











The air conditioning system operates
with the engine running.


)
Turn the dial to select a
position between blue
(cold) and red (hot) so as
to adjust the temperature
to your requirements.

1. Temperature adjustment This dial is used to increase or
decrease the speed of the air
booster fan.
2. Air fl ow adjustment
3. Air distribution adjustment
Windscreen and side windows.

)
If you place the air fl ow con-
trol in position 0
, the system
is deactivated. However, a
slight fl ow of air, due to the
movement of the vehicle,
can still be felt.
Windscreen, side windows
and footwells.
Footwells.
Central and side vents.
The air distribution can be
adapted by placing the dial in
an intermediate position.

)
Turn the dial from position 1
to po-
sition 5
to obtain a comfortable air
fl ow. This dial is used to arrange the distri-
bution of air in the passenger compart-
ment by combining several air outlets.

DUAL-ZONE DIGITAL AIR CONDITIONING

Automatic operation

We recommend the use of
one of the three AUTO modes
available: they provide opti-
mised regulation of the tem-
perature in the passenger
compartment according to the comfort
value that you have chosen.
These three modes automatically adjust
the air fl ow, according to the desired set-
ting, while also maintaining the desired
comfort value.

)

Press the "AU TO "
button repeatedly:


- a fi rst indicator lamp comes on; the
"light" setting mode is selected,

- a second indicator lamp comes
on; the "medium" setting mode is
selected,

- a third indicator lamp comes on;
the "intense" mode setting is se-
lected.
The air conditioning system operates when the engine is running. When the engine is cold, the air
fl ow will reach its optimum level
progressively, taking account
of the weather and the desired
comfort level so as to avoid too
great a distribution of cold air.
On entering the vehicle, if the in-
terior temperature is much colder
or warmer than the comfort val-
ue, there is no need to change
the value displayed in order to
obtain the comfort required. The
system corrects the difference in
temperature automatically and
as quickly as possible.

1. Automatic comfort programme
This system is designed to operate
effectively in all seasons, with the win-
dows closed.

Switching the system off

Avoid prolonged operation in in-
terior air recirculation mode or
driving for long periods with the
system off (risk of condensation
and deterioration of air quality).
9. "REST" function: ventilation with
the engine off

On switching on the engine



- The control screens come on: the
function is available.

- Pressing the REST
button activates
the ventilation for a few minutes.
Activation of the function is con-
fi rmed by the display of two dashes
in the control screens and four air
fl ow level indicator lamps.

- The function can be deactivated and
reactivated if the control screens
are on.

- The screens go off at the end of this
period.
On stopping the engine



- While the control screens remain
on: the function is available.

- Pressing the REST
button activates
the ventilation for a few minutes.
Activation of the function is con-
fi rmed by the display of two dashes
in the control screens and four air
fl ow level indicator lamps.
Locking the vehicle has no effect on
this function.

- The control screens go off at the
end of this period.
Pressing again before the end of
the period interrupts off the ventila-
tion defi nitively: the control screens
go off and the function is no longer
available.

)
Turn the air fl ow control to
the left until all of the indi-
cator lamps go off.
This action switches off the air condi-
tioning and the ventilation.
Temperature related comfort is no longer
assured but a slight fl ow of air, due to
the movement of the vehicle, can still
be felt.


)
Modify the settings (temperature,
air fl ow or air distribution) or press
the "AUTO"
button to reactivate the
system with the values set before it
was switched off.
This switch does not operate the
air conditioning, only the air fan.
When the "REST" function is ac-
tivated, you cannot modify the
temperature, air fl ow and distri-
bution settings: these are con-
trolled automatically according
to the ambient temperature.
This function is not available in
the STOP mode of Stop & Start.
Even with the engine is off,
you can operate the ventila-
tion for a few minutes.
For example, while you are
away from the vehicle, the
passengers can still enjoy some air cir-
culation without having the engine run-
ning.
This function is available after switching
on the ignition, as well as after stopping
the engine.
The period that the function is available
depends on the state of charge of the
battery.
You can activate the "REST" func-
tion while the air conditioning control
screens are on.

automatically to prevent an excessive
consumption of current.


)
It is possible to stop the demisting/de-
frosting operation before it is switched
off automatically by pressing the button
again. The indicator lamp associated
with the button goes off.


)
Switch off the demisting/de-
frosting of the rear screen
and door mirrors as soon as
appropriate, as lower current
consumption results in re-
duced fuel consumption.

conditioning

Automatic visibility programme


)
Select this programme to demist
