Switch off the headlamps and front
foglamps when the level of light does
not require their use.

Avoid running the engine before moving
off, particularly in winter; your vehicle
will warm up much faster while driving.

As a passenger, if you avoid connecting
your multimedia devices (fi lm, music,
video game...), you will contribute to-
wards limiting the consumption of elec-
trical energy, and so of fuel.
Disconnect your portable devices be-
fore leaving the vehicle.



Limit the causes of excess
consumption

Spread loads throughout the vehicle;
place the heaviest items in the bottom
of the boot, as close as possible to the
rear seats.
Limit the loads carried in the vehicle
and reduce wind resistance (roof bars,
roof rack, bicycle carrier, trailer...). Use
a roof box in preference.
Remove roof bars and roof racks after
use.

At the end of winter, remove snow
tyres and refi t your summer tyres.



Observe the recommendations
on maintenance

Check the tyre pressures regularly,
when cold, referring to the label in the
door aperture, driver's side.
Carry out this check in particular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the
tyres on any trailer or caravan.

Have your vehicle serviced regularly
(engine oil, oil fi lter, air fi lter...) and ob-
serve the schedule of operations rec-
ommended by the manufacturer.



When refuelling, do not continue after
the third cut-off of the nozzle to avoid
any overfl ow.


At the wheel of your new vehicle, it is only
after the fi rst 1 800 miles (3 000 kilometres)
that you will see the fuel consumption set-
tle down to a consistent average.

TYRE UNDER-INFLATION
DETECTION

System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as
the vehicle is moving.
A pressure sensor is located in the
valve of a each tyres (except the spare
wheel).
The system triggers an alert if a drop
in pressure is detected in one or more
tyres.
The tyre under-infl ation detection sys-
tem is an aid to driving which does not
replace the need for the driver to be
vigilant or to drive responsibly.
This system does not avoid the
need to check the tyre pressures
regularly (including the spare
wheel) and before a long jour-
ney.
Driving with under-infl ated tyres
adversely affects road holding,
extends braking distances and
causes premature tyre wear,
particularly under arduous con-
ditions (vehicle loaded, high
speed, long journey).

Driving with under-infl ated tyres
increases fuel consumption.
The tyre pressures for your vehi-
cle can be found on the tyre pres-
sure label (see the "Identifi cation
markings" section).
The tyre pressures must be
checked when the tyres cold
(vehicle stopped for 1 hour or
after driving for less then 6 miles
(10 km) at moderate speed).
Otherwise, add 0.3 bar to the val-
ues indicated on the label.

The fl ashing and then fi xed
illumination of the under-infl a-
tion warning lamp accompa-
nied by the illumination of the
"service" warning lamp indi-
cates a fault with the system.

Operating fault

The alert is given by the fi xed il-
lumination of this warning lamp,
accompanied by an audible sig-
nal, and depending on equip-
ment, the display of a message.

Under-inflation alert


The alert is maintained until the
tyre or tyres concerned is rein-
fl ated or repaired.

The loss of pressure detected
does not always lead to visible
deformation of the tyre. Do not
rely on just a visual check.

This alert is also displayed when
one or more wheels is not fi tted
with a sensor.
In the event of a problem on one of
the tyres, the symbol or the message
appears, according to equipment, to
identify it.


Reduce speed, avoid sudden steer-
ing movements or harsh brake ap-
plications.


Stop as soon as it is safe to do so.


In the event of a puncture, use the
temporary puncture repair kit or the
spare wheel (according to equip-
ment),
or


if you have a compressor, the one in
the temporary puncture repair kit for
example, check the four tyre pres-
sures when cold,
or


if it is not possible to check the tyre
pressures at the time, drive care-
fully at reduced speed. In this case, monitoring of the tyre pres-
sures is not assured.
Have the system checked by a
CITROËN dealer or a qualifi ed work-
shop.

Removing the cartridge





Stow the black pipe.


Detach the angled base from the
white pipe.


Support the compressor vertically.


Unscrew the cartridge from the bottom.






Connect the compressor's electri-
cal connector to the vehicle's 12 V
socket.


Start the vehicle and let the engine
run.


Adjust the pressure using the com-
pressor (to infl ate: switch B
in po-
sition "I"
; to defl ate: switch B
in
position "O"
and press button C
),
according to the vehicle's tyre pres-
sure label or the accessory's pres-
sure label.


Remove the kit then stow it.


Beware of discharges of fl uid.
The expiry date of the fl uid is in-
dicated on the cartridge.
The sealant cartridge is designed
for single use; even if only partly
used, it must be replaced.
After use, do not discard the car-
tridge into the environment, take
it to an authorised waste dispos-
al site or a CITROËN dealer.
Do not forget to obtain a new
sealant cartridge, available from
CITROËN dealers or from a
qualifi ed workshop.



Checking tyre pressures /
inflating accessories

You can also use the compressor, with-
out injecting any product, to:


- check or adjust the pressure of your
tyres,

- infl ate other accessories (balls, bi-
cycle tyres...).





Turn the selector A
to the
"Air" position.


Uncoil the black pipe H
fully.


Connect the black pipe to
the valve of the wheel or accessory.
If necessary, fi t one of the adaptors
supplied with the kit fi rst.

TOWING A TRAILER


We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions.
The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer or installation of a bicycle carrier,
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.
Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.



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 towed load
must be reduced by 10 % for every
1 000 metres of altitude.

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 towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the cool-
ant 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 braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres




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



Lighting



Check the electrical lighting and sig-
nalling on the trailer.

Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.

IDENTIFICATION MARKINGS

Various visible markings for the identifi -
cation of your vehicle.

A. Vehicle identifi cation number (VIN)
under the bonnet.

This number is engraved on the bod-
ywork near the suspension damper
mounting.
B. Vehicle identifi cation number on
the dashboard.

This number is indicated on a self-ad-
hesive label which is visible through the
windscreen.
D. Tyre/paint label.

This label is affi xed to the driver's front
pillar.
The tyre pressures must be
checked when the tyres are
cold, at least once a month.
Low tyre pressures increase fuel
consumption.
C. Manufacturer's label.

The VIN is indicated on a self-destroy-
ing label affi xed to the driver's centre
pillar. It bears the following information:


- the tyre pressures, for unladen and
laden conditions,

- the tyre sizes (including the load in-
dex and speed rating),

- the spare tyre infl ation pressure,

- the paint colour code.
