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 status
For information relating to
checking the brake disc wear
status, contact a CITROËN
dealer.
Handbrake If the handbrake travel is
too long or if a loss of ef-
fectiveness of this system
is noticed, the handbrake
must be adjusted, 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 .
Refer to the Maintenance and
Warranty Guide for the details of
the checking interval for this compo-
nent.
Refer to the servicing booklet for de-
tails of the checking interval for this
component.

TOWING THE VEHICLE
Procedure for having your vehicle
towed or for towing another vehicle
using a removable towing eye.
Access to the tools
The tools are located under the boot
fl oor.
To gain access to them:

 open the boot,

 lift up the fl oor,

 detach and remove the holder
containing the tools. Towing your vehicle

 On the front bumper, unclip the
cover by pressing at the top left
and pulling at the right.

 Screw the towing eye in fully.

 Attach the towing bar.

 Switch on the hazard warning
lamps on the towed vehicle.

 Place the gear lever in neutral
(position N on the electronic
gearbox or automatic gearbox). Towing another vehicle

 On the rear bumper, unclip the
cover by pressing at the bottom
at pulling at the top.

 Screw the towing eye in fully.

 Attach the towing bar.

 Switch on the hazard warning
lampson the towed vehicle.
Failure to observe this special con-
dition could result in damage to
certain braking components and
the absence of braking assistance
the next time the engine is started. When towing with all four wheels
on the ground, always use a tow-
ing bar.
When towing with only two wheels
on the ground, always use profes-
sional lifting equipment.
When towing with the engine off,
there is no longer any braking or
steering assistance.

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 original
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 im-
perative that it is fi tted us-
ing 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 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, re-
duce your speed.
The maximum towing load on a long
slope depends on the gradient and
the outside 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.
