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
30 km/h (around 20 mph) must be
programmed.
The speed limiter controls are locat-
ed on the left-hand side of the steer-
ing wheel. The programmed information is
grouped together in zone
A of the
instrument panel display.
Steering wheel controls Displays on 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
and a sustained press in steps of
3 mph.
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 on the
instrument panel. The information
"OFF"
then disappears from
the instrument panel
display.
While the function is active, press-
ing the accelerator pedal will not en-
able the programmed speed to be
exceeded, 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 memo-
rised.
The speed limiter cannot, in any circum-
stances, take the place of the observ-
ance of speed limits or of the vigilance
and responsibility of the driver.

Deactivation
Press on button 3 .
This action causes the
information "OFF" to
appear on the instru-
ment panel display.
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.
If during the operation of the speed
limiter, the system is unable to
keep within the maximum speed
(for example on a steep descent or
under heavy acceleration) then the
speed fl ashes. Adapt your speed as
necessary.
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.

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 (approx. 40 km/h)
and you must engage:
- fourth gear on a manual gearbox,
- second gear, in sequential mode, on an electronic gearbox or au-
tomatic gearbox,
- position A on an electronic gear-
box or D on an automatic gearbox.
Steering wheel 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 display.
Displays on the instrument
panel
Activation You can then release the accelera-
tor pedal. The vehicle will automati-
cally 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
on the instrument panel display by
pressing on:

 button 4 to increase the speed,

 button 2 to decrease the speed.
Successive presses modify the
cruise speed in steps of 1 mph and a
sustained press in steps of 3 mph.

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 button 4 . The cruise
speed is then memorised. It is dis-
played in zone A of the instrument
panel. These actions cause
the information
"OFF"
to appear on the instru-
ment panel display.
These actions do
not cancel the cruise
speed which remains
displayed in the instru-
ment panel.
The cruise control cannot, in any circum-
stances, take the place of the observ-
ance of speed limits or of the vigilance
and responsibility of the driver.

in zone A .
If the memorised cruise speed 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

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

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, par-
ticularly 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 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 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 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.
Refer to the Maintenance and Warranty
Guide for details of the replacement in-
terval for this component.
