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.

Refi tting the wheel Dimension of the spare wheel
If your spare wheel is of different
dimensions to those on the vehicle
(identifi ed by a label), it is essential
to use it only on a temporary basis,
to drive not above 50 mph (80 km/h)
and to have the original wheel refi t-
ted as soon as possible.

Switch on your hazard
warning lamps.

It is imperative to ensure
that the occupants get out of the
vehicle and wait in a safe location.

Never get underneath the vehi-
cle if it is supported only by the
jack; use an axle stand.

The jack is designed specifi cally
for your vehicle, do not use it for
other applications.

Refi t the repaired original wheel
as soon as possible.

With a spare wheel fi tted, drive
with caution.

The wheel should be correctly
positioned fl at in the centre of
its well. Light alloy wheels
If your vehicle is equipped with
light alloy wheels and a steel spare
wheel, then if fi tting the latter it is
normal to note that the heads of the
wheel bolts do not come to bear on
the wheel rim.
The steel spare wheel is secured
by the conical tapering of the wheel
bolts’ shafts, see diagram.
When refi tting the light alloy wheel,
ensure that the wheel bolt heads are
in undamaged condition.

 Refi t the wheel in place.

 Undo the yellow central screw by
a few turns, then position it at the
centre of the wheel.

 Do up the central screw until tight
so that the wheel is securely re-
tained in place.

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.
