LANE DEPARTURE WARNING SYSTEM
System which detects the involun-
tary crossing of longitudinal traffi c
lane markings on the ground (solid
or broken line).
Sensors, fi tted below the front
bumper, trigger a warning if the vehi-
cle drifts over a lane marking (speed
higher than 50 mph (80 km/h)).
This system is particularly useful on
motorways and main roads. Activation

 Press button A , the indicator
lamp comes on.
Deactivation

 Press button A again, the indica-
tor lamp switches off.
The status of the system remains
in the memory when the ignition is
switched off.
Detection
You are warned by the vibration of
the driver's seat cushion:
- on the right-hand side, if the marking on the ground has been
crossed on the right,
- on the left-hand side, if the mark- ing on the ground has been
crossed on the left.
No warning is transmitted while the
direction indicator is active and for
approximately 20 seconds after the
direction indicator is switched off.
A warning may be transmitted if a
direction marking (e.g. arrow) or
non-standard marking (e.g. graffi ti)
is crossed. Operating fault
In the event of a malfunction, the
service warning lamp comes on, ac-
companied by an audible signal and a
message on the multifunction screen.
Consult a CITROËN dealer.
The lane departure warning system
cannot, in any circumstances, re-
place the need for vigilance and re-
sponsibility on the part of the driver. The detection may be impeded:
- if the sensors are dirty (mud, snow...),
- if the markings on the ground
are worn,
- if there is little contrast between the markings on the ground and
the road surface.

152

D R I V I N G In bad weather or in winter, ensure
that the sensors are not covered
with mud, ice or snow. When re-
verse gear is engaged, an audible
signal (long beep) indicates that
the sensors may be dirty.
When the vehicle is being driven
at a speed below approximately
6 mph (10 km/h), certain sourc-
es of noise (motorcycles, lorries,
pneumatic drills, ...) may trigger the
reversing audible signal.

 Press button A again, the warn-
ing lamp switches off, the system
is reactivated.
Reactivation
Deactivation

 Press button A , the warning lamp
comes on, the system is fully de-
activated.
The system will be deactivated au-
tomatically when a trailer is being
towed or when a bicycle carrier is
fi tted (vehicle fi tted with a towbar
or bicycle carrier recommended by
CITROËN). Operating fault
If an operating fault occurs, this warn-
ing lamp is displayed on the instrument
panel and/or a message appears on
the multifunction screen, accompa-
nied by an audible signal (short beep),
when reverse gear is engaged.
Consult a CITROËN dealer.

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 deactivate
the system in the following instances:
- working under the vehicle,
- changing a wheel,
- transporting the vehicle on a
truck or on a boot.
To reactivate the automatic correction:

 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 .

Screenwash and headlamp
wash fluid
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with plain water.
Reservoir capacities:
- screenwash: approximately 3 li- tres,


- screenwash and headlamp wash: approximately 6 litres. Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.

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 deal-
er (France) or an authorised waste
disposal site.
In the case of vehicles fi tted

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your en-
gine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly 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.
Air filter and passenger compartment filter
Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
Depending on the environment (e.g.
dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary
(refer to the "Engines" paragraph).
A clogged cabin fi lter may have an
adverse effect on the performance
of the air conditioning system and
generate undesirable odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed. Particulate 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 occasion-
ally notice water vapour being emit-
ted from the exhaust when acceler-
ating. 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 audi-
ble signal and lighting of the serv-
ice warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in condi-
tions of urban driving of exception-
ally long duration: low speeds, traf-
fi 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.
Refer to the Maintenance and
Warranty Guide for details of the
replacement interval for this compo-
nent.
