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 require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require 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 sys-
tem is noticed, the parking brake
must be checked, even between
two services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent qual-
ity 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 .

Grand C4 Picasso C4 Picasso Access to the spare wheel
Taking out the wheel

 Move the third-row seat, right-
hand side (7 seater model).

 Retrieve the extension that is
attached to the rear of the seat
well.

 Engage the extension on the
pinion, located under the carpet
in the seat well.

 Using the wheel brace 4 on the
extension to turn the pinion
clockwise , release the cable
to lower the spare wheel to the
ground.

 Remove the wheel from under
the vehicle, disengaging the
linking plate in the centre of the
wheel.
The pinion to release the spare wheel
is located under the boot carpet, on
the right hand side in the wheel well
for the Grand C4 Picasso and on the
left hand side for the C4 Picasso. Putting the wheel back in place

 It is essential to direct the valve
upwards.

 Pass the linking plate through
the centre of the wheel (fi rst re-
moving the central trim on cer-
tain alloy wheels).

 Turn the pinion anti-clockwise
to draw in the cable. First the pin-
ion will turn idly, then the cable
will tighten to raise the wheel.
Check that the wheel is tight against the vehicle fl oor and
not interfering with other nearby
components (e.g. the exhaust).

 Stow the tools.
With the damaged wheel
now under the vehicle fl oor,
the vehicle has reduced
ground clearance, so take extra
care when reversing or driving on
uneven surfaces, including kerbs.
Retrieval of the spare wheel and
stowage of the affected road wheel
are operations that should be done
with the vehicle supported on its
wheels, not by the jack.

TOWING THE VEHICLE
Procedure for having your vehicle
towed or for towing another vehicle
using a removable towing eye.
Access to the tools
According to equipment, the towing
eye is installed in the storage fl ap
under the second row passenger
footwell or under the boot fl oor.
To gain access to it:

 open one of the rear doors or the
boot (according to equipment),

 open the fl ap or raise the fl oor
(according to equipment),

 remove the towing eye from the
holder. 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.

 Install 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.

 Install the towing bar.

 Switch on the hazard warning
lamps on 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 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 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
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.
 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 signalling on
the trailer.
The rear parking assistance will
be deactivated automatically if an
original CITROËN towbar is used.
Driving with a trailer subjects the
towing vehicle to more signifi cant
stress and its driver must be particu-
larly careful.
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.
