C4 Picasso
The pneumatic suspension has an
additional function: the possibility to
raise or lower the height of the rear
of the vehicle when stationary, in or-
der to facilitate loading/unloading of
the boot.
Increasing the height of the boot

)
Press continuously the top con-
trol A
, which is located in the
boot, on the left-hand side.
This action will be accompanied by
an audible signal. You can stop the
movement at any time by releasing
the control.
3 beeps will confi rm that the move-
ment has gone as far as it can.
Returning to the normal height
)
Press briefl y the bottom of con-
trol A
twice.
Decreasing the height of the boot
fl oor

Press continuously the bottom of
control A
.
This action will be accompanied by
an audible signal. You can stop the
movement at any time by releasing
the control.

)
Press briefl y the top of control A
twice.
Driving with the boot in a
low position may damage
underbody components.
Particular points
- If you start the vehicle without
having returned it to the normal
height, automatic correction will
activate as soon as the vehicle
starts to move. During the cor-
rection, the service warning
lamp comes on and a message
on the screen reminds you not to
exceed 6 mph (10 km/h).
- Loading assistance does not
function in the following circum-
stances:
- If button B
is illuminated,
- in power economy mode,
- when you fi
rst use the function,
press control A
for two seconds

CHECKS
Screenwash and headlamp wash
fl uid
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be
topped up with or replaced with plain
water.
Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
illumination of the service warning
lamp, accompanied by an audible
warning and a message in the multi-
function screen.
Topping up
This additive must be topped up by
a CITROËN dealer or a qualifi ed
workshop without delay.
Used products
Avoid prolonged contact of
used oil or fl uids with the
skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or
fl uids into sewers or onto
the ground.
Take used oil to a CITROËN dealer
or a qualifi ed workshop (France) or
to an authorised waste disposal
site.
In the case of vehicles fi tted
with headlamp washers, the
low fl uid level is indicated
by an audible signal and a
message in the screen.
Top up the reservoir when you next
stop the vehicle.
Coolant level
Changing the coolant
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer’s recommendations.
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm,
the temperature of the coolant is
regulated by the fan. This can ope-
rate with the ignition off.
On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the
engine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour
after switching off the engine before
carrying out any work.
To avoid any risk of scalding, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.

CHECKS
CHECKS
12 V battery
The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, parti-
cularly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection.
Particle filter system (Diesel)
Complementary to the catalytic
converter, this fi lter makes an ac-
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audible
signal and lighting of the service
warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in conditions
of urban driving of exceptionally long
duration: low speeds, traffi c jams
etc.)
To regenerate the fi lter, it is advised
to drive as soon as possible, when
traffi c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least fi ve minutes (until
the alert message disappears).
If this alert persists, consult a
CITROËN dealer or a qualifi ed
workshop.
The presence of this label, in par-
ticular with the Stop & Start system,
indicates the use of a specifi c 12 V
lead-acid battery with special tech-
nology and specifi cation, for which
the involvement of a CITROËN
dealer or a qualifi ed workshop is
required when replacing or discon-
necting the battery. Failure to observe this recommen-
dation may shorten the life of the
battery.
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and ac-
cording to your engine.
Otherwise, have them checked by
a CITROËN dealer or a qualifi ed
workshop.
Air filter and passenger
compartment filter
Refer to the servicing
booklet for details of the
replacement intervals for
these components.
Depending on the environ-
ment (e.g. dusty atmosphere) and
the use of the vehicle (e.g. city driv-
ing), replace them twice as often
if necessary
(refer to the "Engines"
section).
A clogged passenger compartment
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesir-
able odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed.
Refer to the servicing
booklet for details of the
replacement interval for this compo-
nent.
