DRIVING
SPEED LIMITER
System which prevents the vehi-
cle from exceeding the speed pro-
grammed by the driver.
Once the limit speed has been
reached, the accelerator pedal no
longer has any effect.
The speed limiter is switched on
manually: a speed of at least 20 mph
(approximately 30 km/h) must be
programmed.
The speed limiter controls are located
on the left-hand side of the steering
wheel. The programmed information is
grouped together in zone A
of the
instrument panel screen.


Steering mounted controls
Displays in the instrument
panel

Programming
Rotate the control 1
to the "LIM"
po-
sition.
With the engine running, you can
adjust the memorised maximum
speed , by means of short or long
presses on:


)
button 4
to increase the memo-
rised maximum speed,

)
button 2
to decrease the memo-
rised maximum speed.
Successive presses will modify the
maximum speed in steps of 1 mph
(1 km/h) and a sustained press in
steps of 3 mph (5 km/h).


Activation

When the desired maximum speed
is displayed, press button 3
so that
the limitation is activated.
On selection of the
function, the previous
memorised speed and
the information "OFF"

are displayed in the in-
strument panel. The information "OFF"

then disappears from
the instrument panel
screen.
While the function is active, pressing
the accelerator pedal will not enable
the programmed speed to be ex-
ceeded, except if you press the pedal
hard down to beyond the end-of-travel
switch.
The speed of your vehicle may vary
slightly in relation to that memorised.
The speed limiter cannot, in any circum-
stances, take the place of the obser-
vance of speed limits or of the vigilance
and responsibility of the driver.

DRIVING

Deactivation

Press on button 3
.
This action causes the
information "OFF"
to
appear on the instru-
ment panel screen.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A
of the
instrument panel.


Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is be-
ing exceeded, the displayed speed
fl ashes.
You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again.

Return to normal driving



)
By moving the control 1
from po-
sition "LIM"
to position 0
.

)
By the engine stopping.
The speed previously chosen is still
memorised.


Operating fault

If there is a speed limiter malfunc-
tion, a message will display accom-
panied by an audible signal and
lighting of the service warning lamp.
Have it checked by a CITROËN
dealer or a qualifi ed workshop. If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for ex-
ample on a steep descent or under
heavy acceleration) then the speed
fl ashes. Adapt your speed as neces-
sary.
The function will re-engage when
your speed returns below the de-
sired maximum speed.
On a steep downhill gradi-
ent or on sharp accelera-
tion, the speed limiter will
not be able to prevent the vehicle
from exceeding the programmed
speed.
Use of fl oor mats that are not ap-
proved by CITROËN may hinder
access to the accelerator pedal
and thus interfere with the function-
ing of the speed limiter.
To avoid any risk of interfering with
the pedals:


- check that the fl oor mat is cor-
rectly positioned,

- never use more than one fl oor
mat.

DRIVING
CRUISE CONTROL
System which automatically main-
tains the vehicle speed programmed
by the driver, without any action on
the accelerator pedal.
The cruise control is switched on
manually: the vehicle speed must
be at least 25 mph (approximately
40 km/h) and you must engage:


- fourth gear on a manual gearbox,

- second gear, in manual mode,
on an electronic or automatic
gearbox,

- position A
on an electronic gear-
box or D
on an automatic gearbox.


Steering mounted controls

The cruise control switches are lo-
cated on the left-hand side of the
steering wheel. The programmed information is
grouped together in zone A
of the
instrument panel screen.


Displays in the instrument
panel

Activation
You can then release the accelerator
pedal. The vehicle will automatically
keep to the speed chosen.
The speed of your vehicle may vary
slightly in relation to that memo-
rised.
You can adjust the memorised speed
in the instrument panel screen by
pressing:


)
button 4
to increase the speed,

)
button 2
to decrease the speed.
Successive presses modify the
cruise speed in steps of 1 mph
(1 km/h) and a sustained press in
steps of 3 mph (5 km/h).


Deactivation



)
Either by pressing the brake or
the clutch pedal.

)
Or by pressing button 3
.

)
Or if either the ESP or the ASR
system is active.
The cruise control is not active if the
gear lever is in neutral. On selection of the
function via control 1,
no cruise speed has
yet been memorised.


Programming

Rotate the control 1
to the "REG"

position.
Once the desired speed has been
reached using the accelerator, press
button 2
or 4
. The cruise speed is
then memorised. It is displayed in
zone A
of the instrument panel. These actions cause
the information "OFF"

to appear in the instru-
ment panel screen.
These actions do not
cancel the cruise speed
which remains displayed in the instrument panel.

The cruise control cannot, in any circum-
stances, take the place of the obser-
vance of speed limits or of the vigilance
and responsibility of the driver.

DRIVING

Reactivation



)
By recall of the memorised
speed

After a disengagement, press on
button 3
. Your vehicle automati-
cally returns to the memorised
cruise speed which is displayed

is higher than the current speed,
the vehicle will accelerate to
reach the former.

)
By selection of the current
speed

Press on button 2
or 4
once the
desired speed has been reached.
The information "OFF"
will then
disappear from the instrument
panel display.



Overriding the programmed
speed
During the operation of cruise con-
trol, it is always possible to use the
accelerator to go faster than the
cruise speed (for example to over-
take another vehicle). The speed
displayed in zone A
fl ashes.
You have only to release the accel-
erator pedal to return to the cruise
speed. If during the operation of cruise
control, the system is unable to
keep within the memorised speed
(for example on a steep descent),
then the speed fl ashes. Adapt your
speed as necessary.

Return to normal driving
Operating fault
If there is a malfunction, a message
will display accompanied by an audi-
ble signal and lighting of the service
warning lamp.
Have it it checked by a CITROËN
dealer or a qualifi ed workshop.
Cruise control should only
be used when the driving
conditions allow you to drive
at a constant speed.
Do not use it in heavy traffi c, or on
dangerous or slippery roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to always
keep your feet within range of the
pedals.
To avoid any risk of interfering with
the pedals:


- check that the fl oor mat is cor-
rectly positioned,

- never use more than one fl oor
mat.

PNEUMATIC SUSPENSION

Grand
C4 Picasso

C4 Picasso

The pneumatic rear suspension en-
hances driving comfort by maintain-
ing a constant body height whatever
the vehicle load.

Operation



- If there is an increase in vehicle
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, automatic height correc-
tion will be activated as soon as the
vehicle starts to move. During height
correction, the service warning lamp
comes on and a message on the
screen reminds you not to exceed
6 mph (10 km/h).
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 height correction can
be deactivated:


)
press button B
located on the
left hand boot interior trim for ap-
proximately two seconds,

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

In the event of a system fault,
alert messages, always in asso-
ciation with the service warning
lamp, will appear in the instru-
ment panel . Contact a CITROËN
dealer or a qualifi ed workshop.

You must deactivate the system in
the following circumstances:


- when working under the vehicle,

- when changing a wheel,

- when transporting the vehicle on
a lorry or ferry.
To reactivate automatic height cor-
rection:


)
press button B
again for approxi-
mately two seconds,

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

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.
