Emergency unlocking In the event of the electric parking
brake malfunctioning or the battery
running fl at, an emergency mecha-
nism can unlock the parking brake.

 Immobilise the vehicle, with the
engine running, by engaging fi rst
gear (manual gearbox), posi-
tion P (automatic gearbox) or M
or R (6-speed electronic gear-
box).

 Switch off the engine, but leave
the ignition on.
If the vehicle cannot be immo- bilised, do not do anything and
contact a CITROËN dealer with-
out delay.

 Fetch the vehicle blocks E and
the unlocking tool F (handle)
from the toolbox.

 Immobilise the vehicle by placing
blocks E at the front and at the
rear of one of the rear wheels.

 Slide the front left-hand seat
back as far as possible.
 Lift up the fl oor plug B

you hear a knocking noise. The
parking brake is released.

 Remove the unlocking tool F and
store it with the blocks E in the
toolbox.
- The operation of the parking brake reinitialises when the ig-
nition is switched off then on
again. If the reinitialisation of the
parking brake proves impossi-
ble, contact a CITROËN dealer.
- The subsequent time required for application may be longer
than during normal operation.
For safety reasons, after this manoeuvre it is essential to cont act a CITROËN dealer urgently to have the plug
replaced.
Following an emergency unlocking, immobilisation of the vehi cle is no longer guaranteed once the manual emer-
gency unlocking has been deployed and the manual control doe s not allow the re-application of your parking
brake.
Take no action, either on control A , or stopping starting the engine while the unlocking to ol F is engaged.

VISUAL AND AUDIBLE FRONT AND/OR REAR PARKING ASSISTANCE
System consisting of four proximity
sensors, installed in the front and/or
rear bumper.
It detects any obstacle (person, ve-
hicle, tree, barrier...) located behind
the vehicle, however, it will not be
able to detect obstacles located im-
mediately below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it. The parking assistance is
switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward
gear,
- when the vehicle has been sta- tionary for more than three se-
conds in forward gear.
The parking assistance system
cannot, in any circumstances, re-
place the need for vigilance and
responsibility on the part of the
driver.
The parking assistance is
switched
on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in forward gear.
This is accompanied by an audible
signal and/or displaying of the vehi-
cle on the multifunction screen.
The proximity information is indicat-
ed by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction screen, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the ve-
hicle and the obstacle is less than
approximately thirty centimetres, the
audible signal becomes continuous
and/or the "Danger" symbol appears,
depending on the multifunction screen
version.

PNEUMATIC SUSPENSION

Grand C4
Picasso
C4 Picasso
The rear pneumatic suspension en-
hances driving comfort by maintain-
ing a constant body height whatever
the vehicle load. Operation
- If there is an increase in vehi-
cle load, a sinking of the rear of
the vehicle is detected and the
pneumatic springs infl ate in or-
der to compensate for the extra
weight.
- If there is a decrease in load, a rising of the rear of the vehicle is
detected and so the pneumatic
springs defl ate to return the ve-
hicle to its nominal height.
- If the vehicle has been unused for a long period, the pneumatic
springs may infl ate if necessary
when you unlock or open a door,
so as to return the vehicle to its
nominal height.
If you do not reactivate the system
manually, the automatic correction
will be activated as soon as the ve-
hicle starts to move. During the cor-
rection, the service warning lamp
lights up and a message on the
screen reminds you not to exceed
10 km/h (6 mph).
The automatic correction does not
function if the doors or the boot are
open.
The automatic correction operates
even if your vehicle is in power
economy mode. Activation/Deactivation
The automatic correction can be de-
activated:

 press on the button B for approx-
imately two seconds,

 release the button when you
hear a beep. Deactivation is con-
fi rmed by the lighting of the indi-
cator lamp on the button B .

In the event of the system mal-
functioning, alert messages,
always in association with the
service warning lamp, will dis-
play in the instrument panel .
Consult a CITROËN dealer.
It is essential that you should deac-
tivate the system in the following in-
stances:
- working under the vehicle,
- changing a wheel,
- transporting the vehicle on a
truck or on a boot.
To reactivate the automatic correc-
tion:

 press again on the button B for
approximately two seconds,

 release the button when you hear
a beep. Activation is confi rmed
by the extinction of the indicator
lamp on the button B .

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.

1. Dipped beams (H7-55 W)

2. Main beams (H1-55 W)

3. Sidelamps (H6 W-6 W)

4. Direction indicators
(H21-21 W) In some climatic conditions (e.g.
low temperature or humidity), the
presence of misting on the internal
surface of the glass of the head-
lamps and rear lamps is normal;
it disappears after the lamps have
been on for a few minutes.
The headlamps are fi tted
with polycarbonate glass
with a protective coating:

 do not clean them using a
dry or abrasive cloth, nor
with a detergent or solvent
product,

 use a sponge and soapy water,

 when using a high pressure
washer on persistent marks, do
not direct at the lamps or their
outlines for too long, so as not
to damage their coating and
their seals.

 Do not touch the bulb directly
with your fi ngers, use lint-free
cloths.
Changing a halogen bulb should
only be done after the headlamp
has been switched off for a few
minutes (risk of serious burns).
It is imperative to use only anti-
ultraviolet (UV) type bulbs in order
not to damage the headlamp. Dipped beam headlamps
