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).
Automatic gearbox The gearbox does not re-
quire any maintenance (no
oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake If a loss of effectiveness
of this system is noticed,
the parking brake must be
checked, even between
two services.
This system must be checked by a
CITROËN dealer.
Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cations.
Do not use a dry cloth with an abra-
sive product for the maintenance of
aluminium parts; use a sponge and
soapy water.
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
level checking interval for this com-
ponent.
Refer to the Warranty and
Maintenance Record for details of
the level checking interval for this
component.

BATTERY
Procedure for charging your battery
when it is fl at or for starting the en-
gine using another battery. Starting using another
battery
Access to the battery V6 HDi engine
The battery is located under the
bonnet.
For access to it:

 open the bonnet using the interi-
or release lever, then the exterior
safety catch,

 secure the bonnet stay,

 remove the plastic cover to gain
access to the two terminals,

 unclip the fusebox to remove the
battery, if necessary. The battery is located in the boot under
the left-hand wing trim.
For access to it:

 open the boot,

 open the fl ap and remove the
battery.
 Lift the pins to remove the front
left headlamp cover (V6 HDi en-
gine).

 Connect the red cable to the
positive terminal (+) of the fl at
battery A , then to the positive
terminal (+) of the slave battery B .

 Connect one end of the green or
black cable to the negative ter-
minal (-) of the slave battery B .
V6 HDi engine: the positive ter- minal (-) is located under the red
cover.


Connect the other end of the green
or black cable to the earth point C
on the broken down vehicle.

 Operate the starter, let the engine
run.

 Wait until the engine returns to
idle and disconnect the cables.

ENERGY ECONOMY MODE
System which manages the duration
of use of certain functions to con-
serve a suffi cient level of charge in
the battery.
After the engine has stopped, you can
still use functions such as the audio
and telematics system, windscreen
wipers, dipped headlamps, courtesy
lights, etc. for a maximum combined
duration of thirty minutes.
Switching to economy mode
Once the thirty minutes are over, a
message appears on the multi-function
screen indicating that the vehicle has
switched to economy mode and the
active functions are put on standby.
If the telephone is being used at this
time:
- it will be maintained for 5 minutes with radio-CD hands-free kit,
-
it will be interrupted after 10 minutes
with the MyWay audio-navigation
system,
- you can complete your call with the NaviDrive system.
This period may be signifi cantly re-
duced if the battery charge is low. Exiting economy mode
These functions are reactivated auto-matically next time the vehicle is
driven.

 In order to resume the use of
these functions immediately,
start the engine and let it run for
a few minutes.
The time available will then be dou-
ble the duration for which the engine
was left running. However, this time
will always be between fi ve and thirty
minutes.
A fl at battery prevents the en-
gine from starting (refer to the
corresponding paragraph).

TOWING A TRAILER, A CARAVAN, ETC.
Towbar suitable for the attachment
of a trailer or caravan 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. If the trailer is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted using the
electrical pre-equipment installed
at the rear of the vehicle, in accor-
dance with the manufacturer's in-
structions.
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, re-
duce 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 lighting and
signalling on the trailer.
The rear parking sensors will be de-
activated automatically if a genuine
CITROËN towbar is used.
