Screenwash and headlamp
wash fluid
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be
topped up or replaced with water.
Reservoir capacities:
-
screenwash: approximately 3.5 litres,
- screenwash and headlamp wash: approximately 6.15 litres. Diesel additive level
(Diesel engine with particle
emission filter)
A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.
Used products
Avoid prolonged contact of
used oil or fl uids with the skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or
fl uids into sewers or onto the
ground.
Take used oil to a CITROËN dealer
(France) or an authorised waste
disposal site.
In the case of vehicles fi tted
with headlamp washers, the
minimum level of this fl uid is
indicated by an audible sig-
nal and a message on the multifunc-
tion screen.
Top up the level when you stop the
vehicle.
Coolant level
Coolant change
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations. The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate 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.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection.
Air filter and passenger compartment filter
Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
Depending on the environment (e.g.
dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary
(refer to the “Engines” section).
A clogged passenger compartment
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesirable
odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed. Particle filter system (Diesel)
Complementary to the catalytic
converter, this fi lter makes an ac-
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of clogging, a mes-
sage appears on the instrument
panel display, accompanied by an
audible signal and lighting of the
service warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in condi-
tions of urban driving of excep-
tionally long duration: low speeds,
traffi c jams etc.).
To regenerate the fi lter, it is advised to drive as soon as possible, when
traffi c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least fi ve minutes (until
the alert message disappears).
If this alert persists, consult a
CITROËN dealer.
Refer to the Maintenance and
Warranty Guide for details of
the replacement interval for this
component.

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.
Manual gearbox
The gearbox does not
require any maintenance
(no oil change).
Automatic gearbox The gearbox does not
require any maintenance
(no oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake If a loss of effectiveness
of this system is noticed,
the parking brake must be
checked, even between
two services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent quality
and specifi cations.
Do not use a dry cloth with an abra-
sive product for the maintenance of
aluminium parts; use a sponge and
soapy water.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
fers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly
prohibited .
Refer to the Maintenance and
Warranty Guide for the details of the level checking interval for this com-
ponent.
Refer to the Warranty and
Maintenance Record for details of
the level checking interval for this
component.

ENERGY ECONOMY MODE
System which manages the duration
of use of certain functions to con-
serve a suffi cient level of charge in
the battery.
After the engine has stopped, you can
still use functions such as the audio
and telematics system, windscreen
wipers, dipped headlamps, courtesy
lights, etc. for a maximum combined
duration of thirty minutes.
Switching to economy mode
Once the thirty minutes are over, a
message appears on the multi-function
screen indicating that the vehicle has
switched to economy mode and the
active functions are put on standby.
If the telephone is being used at this
time:
- it will be maintained for 5 minutes with radio-CD hands-free kit,
-
it will be interrupted after 10 minutes
with the MyWay audio-navigation
system,
- you can complete your call with the NaviDrive system.
This period may be signifi cantly re-
duced if the battery charge is low. Exiting economy mode
These functions are reactivated auto-matically next time the vehicle is
driven.

 In order to resume the use of
these functions immediately,
start the engine and let it run for
a few minutes.
The time available will then be dou-
ble the duration for which the engine
was left running. However, this time
will always be between fi ve and thirty
minutes.
A fl at battery prevents the en-
gine from starting (refer to the
corresponding paragraph).

TOWING A TRAILER, A CARAVAN, ETC.
Towbar suitable for the attachment
of a trailer or caravan with additional
lighting and signalling.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to a
CITROËN dealer. If the trailer is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted using the
electrical pre-equipment installed
at the rear of the vehicle, in accor-
dance with the manufacturer's in-
structions.
Driving with a trailer subjects the
towing vehicle to more signifi cant
stress and its driver must be par-
ticularly careful.
Driving advice
Distribution of loads

 Distribute the load in the trailer
so that the heaviest items are as
close as possible to the axle and
the nose weight approaches the
maximum permitted without ex-
ceeding it.
Air density decreases with altitude,
thus reducing engine performance.
Above 1 000 metres, the maximum
towing load must be reduced by 10 %
and so on for every 1 000 metres of
altitude.
Refer to the "Technical Data" section
for details of the weights and towing
loads which apply to your vehicle.
Side wind

 Take into account the increased
sensitivity to side wind. Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled,
its cooling capacity is not dependent
on the engine speed.

 To lower the engine speed, re-
duce your speed.
The maximum towing load on a long
slope depends on the gradient and
the ambient temperature.
In all cases, pay attention to the
coolant temperature.

 If the warning lamp and
the STOP warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.
Braking
Towing a trailer increases the brak-
ing distance.
Tyres

 Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.
Lighting

 Check the electrical lighting and
signalling on the trailer.
The rear parking sensors will be de-
activated automatically if a genuine
CITROËN towbar is used.
