Instruments and controls
FUEL GAUGE
The fuel level is tested each time the key is
turned to the “running” position.
The gauge is positioned on:
- F (Full): the capacity of the fuel tank is
approximately 45 litres .
- E (Empty): the reserve is now being
used, the warning light comes on
continuously.
The reserve when the warning first comes
on is approximately 6 litres.
COOLANT TEMPERATURE

The needle is positioned between C
(Cold) and H (Hot): normal operation.
In arduous conditions of use or hot climatic
conditions, the needle may move close to
the red graduations. - wait for approximately 5 minutes to allow
the engine to cool down, then check the
level and if necessary top up.
The cooling circuit is pressurised. In
order to avoid any risk of burns, unscrew
the cap 2 turns to release the pressure.
When the pressure has dropped, check the
level and remove the cap to top up. If the
needle remains in the red zone, contact a
CITROËN dealer EOBD (European On Board Diagnosis) is
a diagnostics system which complies with,
among others, the standards concerning
authorised emissions of:
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrogen oxides) or particles detected by oxygen sensors placed
upstream and downstream of the catalytic
converters.
Refer to the “Levels” section of
chapter 7.
Refer to the “Levels” section of
chapter 7.
Therefore, the driver is warned of
any malfunction of this emission
control system by the flashing of
this specific warning light on the
instrument panel.

What you should do if the needle
enters the red zone, or if the warning
light comes on:
- stop immediately, switch off the ignition. The fan may continue to operate for
a certain time up to approximately
10 minutes.

IN-CAR TECHNOLOGY
Parking assistance
AUDIBLE REAR PARKING ASSISTANCE
The audible system consists of four
proximity sensors, installed in the rear
bumper.
It detects any obstacle which enters the
field: person, vehicle, tree, fence, behind the
vehicle during the manoeuvre.
However, it will not be able to detect
obstacles located immediately below the
bumper.
An object, such as a stake, a roadworks
cone or any other similar object may be
detected at the beginning of the manoeuvre
but may no longer be detected when the
vehicle moves close to it. Stop the assistance
Change to neutral.
Operating fault
If this warning lamp or the service
warning lamp lights up on the
instrument panel, accompanied
by a message on the display,
contact your CITROËN dealer.
Good practice
In bad weather or in winter, ensure that the
sensors are not covered with mud, ice or
snow.
Engage reverse gear
The proximity information is indicated by an
audible signal which becomes more rapid as
the vehicle approaches the obstacle.
When the distance between the rear of
the vehicle and the obstacle is less than
approximately thirty centimetres, the audible
signal becomes continuous.
This function will be deactivated
automatically if a trailer is being towed.
You are advised to obtain a towbar
recommended by CITROËN and have it
installed by a professional.
If anomalies are detected on engaging
reverse gear, the warning light comes on,
possibly accompanied by a message on the
display.

ERGONOMICS and COMFORT
Practical information
INTERIOR LIGHTING
Front courtesy light
This is located in the centre of the roof.
It can be activated by:
- tilting the lens,
- opening or closing a door,
- locking or unlocking the vehicle.
It switches off automatically, after a few
minutes, if the doors remain open, or when
the ignition is switched on.
The courtesy light may be fitted with an
alarm sensor, a microphone for the hands-
free kit and reading lights.
The reading lights have right-hand and left-
hand switches.
Rear courtesy light
This is located on the upper part of the rear
right side.
Press the courtesy light lens to switch it on
or off.
It comes on automatically when a door is
opened.
Good practice
It switches off automatically:
- if the switch is not pressed down,
- in all cases within approximately 15 minutes if the doors remain open,
- when the ignition is switched on.

Towing a trailer
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning light comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the “Levels” section of chapter 7.

Tyres: check the tyre pressures of the
towing vehicle (see the “Identification
features” section of chapter 7) and of
the trailer, observing the recommended
pressure.

Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.

ABS: the system only controls the vehicle,
not the trailer.
Rear parking assistance :
the assistance will be deactivated
automatically when a CITROËN towbar is
used (see the “Rear parking assistance”
section of chapter 4).
Towbar
We recommend the use of CITROËN
towbars and their harnesses, which have
been tested and approved from the design
stage of your vehicle, and that the fitting of
this equipment is entrusted to a CITROËN
dealer .
If this equipment is not fitted by a CITROËN
dealer , it is essential that it is fitted using
the electrical pre-equipment located at the
rear of the vehicle in accordance with the
manufacturer ’s instructions.
The operation of the sensors is deactivated
automatically when the pin of the trailer
cable is inserted in the towbar socket.
When the trailer cable pin is removed, the
sensors are re-activated.

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. The air density decreases with
altitude, so reducing the performance of
the engine. The maximum towed load must
be reduced by 10 % for each 1000 metres
of altitude. Refer to the “Technical data”
chapter for details of the weights and
towed loads applicable to your vehicle and
also to the administrative documents (V5
registration document, ...).

TROUBLESHOOTING
Checks
CHECKS

Bleeding the water contained in the
diesel filter
If this warning light comes on,
bleed the filter, otherwise bleed
regularly each time the engine is
drained.
To evacuate the water, unscrew the bleed
screw or the water in diesel sensor, located
at the base of the filter. Operate until all
of the water has been drained out. Then
tighten the bleed screw or the water sensor.
HDi engines use advanced technology. All
work requires a special qualification which is
guaranteed by a CITROËN dealer .

Battery
At the start of winter, have it checked by a
CITROËN dealer .
Air filter and passenger compartment
filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are indicated
in the servicing booklet.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary, refer to the “Under the
bonnet” section of chapter 7.

Brake pads
Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Unless there is a leak on the circuit, a drop
in the brake fluid level indicates that the
brake pads are worn.

Brake disc/drum wear status
For any information relating to checking
the brake disc/drum wear status, consult a
CITROËN dealer .
Handbrake
Where the handbrake travel is too great
or there is a reduction in the performance
of the system, the handbrake should be
adjusted, even between services.
Have it checked by a CITROËN dealer .

Oil filter
Change the filter regularly, in accordance
with the servicing schedule.
Manual gearbox
Have the level checked in accordance with
the manufacturer ’s servicing schedule.
To check the main levels and certain
components, in accordance with the
manufacturer ’s servicing schedule, refer
to the pages of the servicing booklet which
correspond to your vehicle’s engine.
Only use products recommended by
CITROËN or products of equivalent quality
and characteristics.
In order to optimise the operation of units as
important as the braking circuit, 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.
