Side airbags *
System which protects the driver
and front passenger in the event of
a serious side impact in order to limit
the risk of injury to the chest.
Each side airbag is incorporated in
the front seat back frame, on the
door side.
Operation
It is triggered unilaterally in the
event of a serious side impact ap-
plied to all or part of the side impact
zone
B , perpendicular to the longi-
tudinal centreline of the vehicle on
a horizontal plane and directed from
the outside towards the inside of the
vehicle.
The side airbag infl ates between the
front occupant of the vehicle and the
corresponding door trim pad. Impact detection zones

A. Front impact zone.

B. Side impact zone.

Curtain airbags *
System which protects the driver
and passengers (with the exception
of the rear centre passenger) in the
event of a serious side impact in or-
der to limit the risk of head injuries.
Each curtain airbag is incorporated
in the pillars and the upper part of
the passenger compartment. Operation
It is triggered at the same time as the
corresponding side airbag in the event
of a serious side impact applied to all or
part of the side impact zone
B , perpen-
dicular to the longitudinal centreline of
the vehicle on a horizontal plane and
directed from the outside towards the
inside of the vehicle.
The curtain airbag infl ates between
the front or rear occupant of the ve-
hicle and the windows.
In the event of a minor impact or
bump on the side of the vehicle or
if the vehicle rolls over, the airbag
may not be triggered.
The airbag is not triggered in the
event of a rear or front collision.

Automatic application,
engine off
With the vehicle stationary, the park-
ing brake is automatically applied
when the engine is switched off .
The application of the parking brake
is confi rmed by: - the lighting of warning lamp P on control A and
on the instrument panel, Automatic release
The electronic parking brake
releases
automatically and progressively
when you press the accelerator:

 Manual gearbox (fi rst gear or
reverse gear engaged): press
down fully on the clutch pedal
then press on the accelerator
pedal and move off.

 Automatic gearbox : accelerate
with the selector in position D , M
or R .

 Electronic gearbox : accelerate
with the selector in position A , M
or R .
Full release of the parking brake is
confi rmed by: - the extinction of warning lamp P on control A and
on the instrument panel,
- the display of a message "park- ing brake released" on the multi-
function screen.
When stationary, with the
engine running, do not
press the accelerator pedal
unnecessarily, as you may
release the parking brake.
Maximum application
If necessary, you can utilise
maxi-
mum application of the parking
brake. It is obtained by means of
a long pull on control A , until you
see the message "parking brake ap-
plied" and a beep is heard.

Maximum application is essential:
- in the case of a vehicle towing a caravan or a trailer, if the au-
tomatic functions are activated
but you are applying the parking
brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on
a ferry, in a lorry, during towing),
- in the case of towing, a loaded vehicle or parking on a gradient,
turn the front wheels towards the
pavement and engage a gear
when you park,
- after a maximum application, the release time will be longer.
Before leaving the vehicle,
check that warning lamp P
on the instrument panel is
permanently lit.
Never leave a child alone inside the
vehicle with the ignition on, as they
could release the parking brake.
- the display of a message "parking
brake applied" on the multifunc-
tion screen (except NaviDrive).

with mud, ice or snow. When re-
verse gear is engaged, an audible
signal (long beep) indicates that
the sensors may be dirty.

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.

at pulling at the top.

 Screw the towing eye in fully.

 Install the towing bar.

 Switch on the hazard warning

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.
