PRACTICAL INFORMATION

)
Connect the compressor's elec-
tric plug to the vehicle's 12 V
socket again.

)
Start the vehicle again and leave
the engine running.

)
Adjust the pressure using the
compressor (to infl ate: switch A

in position "1"
; to defl ate:
switch A
in position "0"
and
press button B
), in accordance
with the vehicle's tyre pressure
label (located on the door aper-
ture on the driver's side), then re-
member to check that the leak is
plugged correctly (no further loss
of pressure after several miles).

)
Remove the compressor, then
store the whole kit.

)
Drive at reduced speed (50 mph
[80 km/h]).

)
Visit a CITROËN dealer or a
qualifi ed workshop as soon as
possible to have the tyre repaired
or replaced by a technician. Take care, the sealant
cartridge contains ethyl-
ene-glycol. This product is
harmful if swallowed and causes
irritation to the eyes. Keep it out of
reach of children.
The expiry date of the sealant is
indicated on the base of the car-
tridge.
The cartridge is designed for a sin-
gle use; even if only partly used, it
must be replaced.
After use, do not discard the car-
tridge into the environment, take it
to a CITROËN dealer or to an au-
thorised waste disposal site.
Do not forget to obtain a new
sealant cartridge, available from
a CITROËN dealer or a qualifi ed
workshop.


Under-inflation detection

If the vehicle is fi tted with tyre under-
infl ation detection, the tyre under-
infl ation warning lamp will remain on
after the wheel has been repaired
until the system is reinitialised by
a CITROËN dealer or a qualifi ed
workshop.

CHANGING A FUSE

Access to tools

The extraction tweezer A
is located
on the back of the dashboard fuse-
box cover.
For access to it:


)
open the glove box lid,

)
unclip the fusebox cover by pull-
ing the top right, then left,

)
pull the cover down,

)
remove the tweezer.



Changing a fuse



)
Use the special tweezer A
to re-
move the fuse from its housing
and check the condition of the
fi lament.

)
Replace the failed fuse with a
fuse of the same rating (same
colour)
.
A different rating may cause a
malfunction (risk of fi re).
If the fault occurs again soon after
replacing the fuse, have the electri-
cal system checked by a CITROËN
dealer or a qualifi ed workshop.

Your vehicle’s electrical
system is designed to oper-
ate with either standard or
optional equipment.
Before installing electrical equip-
ment or accessories on your vehi-
cle, consult a CITROËN dealer or a
qualifi ed workshop.
CITROËN declines all responsibil-
ity for the consequences and costs
that are caused by faults or repairs
on your vehicle resulting from the in-
stallation of accessories that are not
supplied and/or not recommended by
CITROËN and not installed according
to its instructions, particularly when
the energy consumption of all of the
additional accessories connected ex-
ceeds 10 milliamperes (Ma). Before replacing a fuse:


- the cause of the failure must be
identifi ed and rectifi ed,

- all electrical consumers must be
switched off,

- your vehicle must be stationary
with the engine off.
Identify the failed fuse by reference
to the tables and layout drawings
below.

PRACTICAL INFORMATION
12 V BATTERY
Procedure for starting the engine
using another battery or for charging
your fl at battery.


The Stop & Start battery does not
have to be disconnected for charging.







The presence of this label, in
particular with the Stop & Start
system, indicates the use of
a 12 V lead-acid battery with
special technology and specifi cation;
the involvement of a CITROËN deal-
er or a qualifi ed workshop is essential
when replacing or disconnecting the
battery.

After refi tting the battery, the Stop &
Start system will only be active after
a continuous period of immobilisa-
tion of the vehicle, a period which
depends on the climatic conditions
and the state of charge of the bat-
tery (up to about 8 hours).

*
or position P
for an automatic gear-
box.


Access to the battery

Before doing any work
Immobilise the vehicle: ap-
ply the parking brake, put
the gearbox in neutral * , then switch
off the ignition.
Check that all electrical equipment
is switched off.


Check that the battery posts and
terminals are clean. If they are
covered with sulphate (white or
green deposit), disconnect them
and clean them.

Batteries contain harmful
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 cell batteries and vehi-
cle batteries to an authorised col-
lection point.
The battery is located under the
bonnet.
For access to the (+) terminal:


)
Release the bonnet using the
interior lever, then the exterior
safety catch,

)
raise the bonnet and secure it
with its stay,

)
lift the plastic cover for access to
the (+) terminal.

PRACTICAL INFORMATION

Towbar suitable for the attachment
of a trailer 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 or a qualifi ed
workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted in accordance with the
vehicle 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 ex-
ceeding 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.
Refer to the "Technical Data" section
for details of the weights and towed
loads which apply to your vehicle.

Side wind


)
Take into account the increased
sensitivity to side wind.


)
To lower the engine speed, re-
duce your speed.
The maximum towed load on a long
incline depends on the gradient and
the ambient temperature.
In all cases, keep a check on 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.
To avoid overheating of the brakes
on a long mountain type of descent,
the use of engine braking is recom-
mended.

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
deactivated automatically if a gen-
uine CITROËN towbar is used.
Driving with a trailer places greater
demands on the towing vehicle and
the driver must take particular care.

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.
