D R I V I N G In the event of a steep descent or
under excessive acceleration, the
speed limiter (which does not act
on the brakes) may not be able to
prevent the vehicle from exceeding
the programmed speed.
Use of a fl oor mat other than that
recommended by CITROËN may
affect the normal operation of the
accelerator pedal and hamper the
operation of the speed limiter.

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, par-
ticularly 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
notice 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 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 compo-
nent.

Charging the battery using a
battery charger

 Disconnect the battery from the
vehicle.

 Follow the instructions for use
provided by the manufacturer of
the charger.

 Reconnect starting with the neg-
ative terminal (-).

 Check that the terminals and
connectors are clean. If they are
covered with sulphate (whitish or
greenish deposit), remove them
and clean them.
The batteries contain harm-
ful substances such as sul-
phuric acid and lead. They
must be disposed of in accordance
with regulations and must not, in
any circumstances, be discarded
with household waste.
Take used remote control batteries
and vehicle batteries to a special
collection point.
It is advisable to disconnect the
battery if the vehicle is to be left un-
used for more than one month. Do not disconnect the ter-
minals while the engine is
running.
Do not charge the batteries without
disconnecting the terminals fi rst.
Do not touch the clips during the
operation.
Do not lean over the batteries.
Disconnect the cables in the re-
verse order to connection, ensur-
ing that they do not touch.
Before disconnecting the
battery
Wait 2 minutes after switching off
the ignition before disconnecting
the battery.
Close the windows and the doors
before disconnecting the battery. Following reconnection of the
battery
Following reconnection of the bat-
tery, switch on the ignition and wait
1 minute before starting to permit
initialisation of the electronic sys-
tems. However, if slight malfunctions
remain following this operation, con-
tact a CITROËN dealer.
Referring to the corresponding sec-
tion, you must yourself reinitialise:
- the remote control key,
- the glass panoramic roof blind,
- the GPS satellite navigation
system.

P R A C T I C A L I N F O R M A T I O N
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.
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
imperative that it is fi tted
using the electrical pre-equipment
installed at the rear of the vehicle,
in accordance with the manufactur-
er’s instructions.
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, 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.
