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 engine
and conform to the manufacturer'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 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, unscrew
the cap by two turns to allow the pres-
sure 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.

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 require
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 information"
section for details of the precautions
to be taken before disconnecting 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" paragraph).
A clogged cabin fi lter may have an
adverse effect on the performance
of the air conditioning 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 multifunction
screen, 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 conditions
of urban driving of exceptionally 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 re-
quire any maintenance (no
oil change).
6-speed electronic gearbox
system The gearbox does not re-
quire any maintenance (no
oil change).
Automatic gearbox The gearbox does not re-
quire 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.
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 .

TOWING A TRAILER,A CARAVAN, ETC.
Towbar suited to the attachment of a
trailer or caravan with additional sig-
nalling and lighting.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer. If the trailer is not fi tted by a
CITROËN dealer, it is imper-
ative that it is fi tted using the
electrical pre-equipment installed at
the rear of the vehicle, in accordance
with the manufacturer's instructions.
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 exceeding 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 me-
tres 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, reduce
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 signalling on
the trailer.
The rear parking assistance will
be deactivated automatically if an
original CITROËN towbar is used.
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. Driving with a trailer subjects the
towing vehicle to more signifi cant
stress and its driver must be particu-
larly careful.
