FUEL GAUGE
The fuel level is tested each time the key is
turned to the "running" position.
The gauge is positioned on:
- 1: the fuel tank is full, approximately 80 litres.
- 0: the reserve is now being used, the warning lamp comes on continuously.
COOLANT TEMPERATURE
The needle is positioned before the red
zone: normal operation.
In arduous conditions of use or hot climatic
conditions, the needle may move close to
the red graduations. What you should do if the warning lamp
comes on:

- stop immediately, switch off the ignition. The fan may continue to operate for
a certain time, up to approximately
10 minutes,
- wait for the engine to cool down in order to check the coolant level and top it up if
necessary.
Refer to the "Fuel" section of chapter 6. What you should do if the needle enters
the red zone:

Reduce your speed or let the engine run at
idle. Refer to the "Levels" section of
chapter 6.
The reserve when the warning first comes
on is approximately 8 litres. As the cooling system is pressurised, follow
this advice in order to avoid any risk of
scalding:
- wait at least one hour after switching off
the engine before carrying out any work,
- unscrew the cap by 1/4 turn to allow the pressure to drop,
- when the pressure has dropped, check the level on the expansion bottle,
- if necessary, remove the cap to top up.
If the needle remains in the red zone, have
the system checked by a CITROËN dealer
or a qualified workshop.

Ventilation
Intake of exterior air Recommended settings
For optimum operation of the manual system, the settings below are recom\
mended:
The LED in the button is off.
This is the preferred operating
position. Recirculation of interior air
The LED in the button is on.
Recirculation temporarily prevents
exterior odours and smoke
from entering the passenger
compartment.
Used with the air conditioning switched on
and setting of the force of blown air (from 1
to 4), recirculation enables you to obtain
the required ambient air comfort level more
quickly with both hot or cold settings.
This position should only be temporary.
When your ambient air comfort level has
been reached, return to the intake of exterior
air position to permit renewal of the air in the
passenger compartment and avoid misting.
This operating mode is preferable. If I require...

DIGITAL AIR CONDITIONING WITH SEPARATE SETTINGS
Good practice
For maximum cooling or heating of the
passenger compartment, it is possible to exceed
the value 15 by turning until LO is displayed or
the value 27 by turning until HI is displayed.
For optimum comfort, the difference between
the value displayed for the driver and for the
passenger should not be greater than 3.
If your vehicle is fitted with this control
panel, it is located on the centre console.
On entering the vehicle, the inside
temperature may be much colder
(or warmer) than is comfortable. There is no
advantage in changing the value displayed
in order to quickly reach the level of comfort
required. The system will use its maximum
performance to reach the comfort value set.

Air flow
Press the small fan button to
reduce the flow or the large fan
button to increase the flow.
On the display, the blades of the fan darken
when the flow is increased. Manual operation
You can, according to your requirements,
make a different selection from that offered
by the system by changing a setting.
The other functions will still be controlled
automatically. Pressing the AUTO button
restores fully automatic operation. Intake of exterior air /
Recirculation of interior air
Press this button to recirculate
the interior air. The recirculation
symbol is displayed.
Recirculation prevents exterior odours
and smoke from entering the passenger
compartment. Avoid prolonged operation
in interior air recirculation mode (risk of
condensation, odour and humidity).
Pressing this button again activates the
intake of exterior air.
Air distribution
Pressing this button several times
in succession directs the air flow
towards:
- the windscreen,
- the windscreen and footwells,
- the footwells,
- the side vents, central vents and footwells,
- the side vents and central vents. Deactivating the system
Press the air flow
small fan
button until the fan symbol
disappears.
This action deactivates all of the system's
functions, with the exception of the air
recirculation and rear screen demisting
(if fitted on your vehicle). Your comfort
setting is no longer maintained and is
switched off.
For your comfort, do not
deactivate the system for long
periods. Pressing the large
fan button or the AUTO button
reactivates the system with
the values set before it was
deactivated. Switching the air conditioning
On / Off
Press this button, the
A/C
symbol is displayed and the air
conditioning is activated.
Pressing this button again switches off the

Good practice
To avoid any risk of poisoning or
asphyxiation, the heater must not be used,
even for short periods, in an enclosed space
such as a garage or workshop which is not
fitted with an exhaust gas extraction system.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire. The temperature near the heater must not
exceed 120 °C. A temperature higher than
this (for example in the case of painting in
an oven) could damage the components of
the electronic circuits.
The heater is supplied by the vehicle's fuel
tank. Ensure that the low fuel warning lamp
is not on.
ADDITIONAL HEATING
Coolant circuit heater
This is an additional and separate system
which heats the Diesel engine cooling
system to make starting easier.
It improves the demisting and defrosting
performance.
Vehicles fitted with an HDi engine may be
fitted with a heater. When the engine is at
idle or the vehicle is stationary, it is normal
to notice a high-pitched whistling noise and
a slight emission of smoke and odour.

For more information about weights,
refer to the administrative documents
(registration document, ...) or to the
"Weights" section of chapter 8.
TOWING A TRAILER, CARAVAN, BOAT, ETC...
Distribution of loads
Distribute the load in the trailer so that the
heaviest objects are as close as possible
to the axle and the nose weight is close to
the maximum authorised without, however,
exceeding it. Cooling

Towing a trailer on a slope increases the
coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.

CHECKS
6
Cooling system
Only use the fluid recommended by the
manufacturer.
Otherwise, you risk seriously damaging your
engine.
When the engine is warm, the temperature
of the coolant is controlled by the engine
fan. As this fan can operate with the ignition
key removed and because the cooling
system is pressurised, wait for at least one
hour after the engine has stopped before
carrying out any work.
Slacken the cap by 1/4 of a turn to release
the pressure to prevent any risk of scalding.
When the pressure has dropped, remove the
cap and top up the level with coolant.
If fluid has to be added frequently, this
indicates a fault which must be checked by a
CITROËN dealer or a qualified workshop as
soon as possible.
Power steering fluid level
The vehicle must be parked on level ground
with the engine cold. Unscrew the cap
integrated with the gauge and check the
level which must be between the MIN and
MAX marks. When this occurs with the engine running it
is due to the start of saturation of the particle
emission filter (exceptionally prolonged
urban type driving conditions: low speed,
long traffic jams, ...).
In order to regenerate the filter, you are
advised to drive at a speed higher than
40 mph (60 km/h) for at least five minutes
as soon as possible, when traffic conditions
permit (until the message disappears and
the service warning lamp goes off).
During regeneration of the particle emission
filter, relay noise may be heard under the
dashboard.
If the message is still displayed and if the
service warning lamp remains on, contact a
CITROËN dealer or a qualified workshop.
Topping up
The level must be between the MIN and
MAX marks on the expansion bottle. If
more than 1 litre of fluid is required to top
up the level, have the system checked by a
CITROËN dealer or a qualified workshop.
Screenwash and headlamp wash
level
For best quality cleaning and for your safety,
we would advise that you use products of
the CITROËN range.
Capacity of the screenwash reservoir:
approximately 4.5 litres.
If your vehicle is fitted with headlamp
washers, the capacity of the reservoir
is 7.5 litres.
To ensure optimum cleaning and prevent
freezing, this fluid must not be topped up or
replaced with plain water.
Diesel additive level
(Diesel with particle
emission filter)
The minimum level of this additive
is indicated by lighting of the service warning
light, accompanied by an audible signal and
a message in the screen. Topping up
This additive must be topped up by a
CITROËN dealer or a qualified workshop
without delay.

Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the maintenance and warranty
guide which correspond to your vehicle's
engine. Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
In order to avoid damaging the electrical
units, high pressure washing to clean the
engine compartment is strictly prohibited.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes.
Bleeding the water contained in the
Diesel filter
If this warning lamp comes on,
bleed the filter. Otherwise bleed
regularly each time the engine oil
is changed.
To evacuate the water, unscrew the bleed
screw located on the end of the transparent
pipe.
Operate until all of the water in the
transparent pipe has been drained out then
tighten the bleed screw.
HDi engines use advanced technology.
Contact a CITROËN or a qualified workshop
for all work on the system. 1.6 litre HDi

2 litre HDi
During this regeneration, you may notice
that the idling speed is higher than normal
and that the cooling fan is running. As
operation of the exhaust emissions controls
may cause the exhaust gas temperature to
reach very high levels, it is recommended
that you do not stop the vehicle over easily
inflammable surfaces (dry grass and leaves,
pine needles, edge of a meadow or forest).

128
Snow screen
REMOVABLE SNOW SCREEN
According to country, the removable snow
screen is installed on the lower part of the
front bumper to prevent the accumulation of
snow at the radiator cooling fan.
FITTING
- Offer up the snow screen facing its centring pin A on the front bumper.
- Put it in place by pressing at each clip B
located in the four corners.
Do not forget to remove the snow screen
when the exterior temperature is higher than
10°C (no risk of snowfall) and when towing.
REMOVAL
- Pass a screwdriver into the hole located near each of the clips.
- Use the screwdriver as a lever to unclip the four clips B in turn.
6. REFITTING THE REPAIRED
WHEEL
The wheel is refitted as described in step 5,
not forgetting to refit the wheel trim.
Refer to the "Identification markings"
section of chapter 8 to locate the tyre
label.
The spare wheel is not designed to be
used over long distances. Have the
tightening of the bolts and the tyre pressure
checked by a CITROËN dealer or a qualified
workshop as soon as possible. Also, have
the original wheel repaired and refitted by a
CITROËN dealer or a qualified workshop as
soon as possible.
