SPEED LIMITER
System which prevents the vehicle from
exceeding the speed programmed by
the driver.
Once the limit speed has been
reached, the accelerator pedal no
longer has any effect.
The speed limiter is switched on manu-
ally: a speed of at least 30 km/h (around
20 mph) 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 display.

Programming
Rotate the control
1 to the "LIM"
position. 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: The information
"OFF"
then disappears from
the instrument panel
display.
While the function is active, pressing
the accelerator pedal will not enable
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 memorised.
The speed limiter cannot, in any
circumstances, take the place of
the observance 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
position "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 a sound 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 exam-
ple 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
approved by CITROËN may hinder
access to the accelerator pedal and
thus interfere with the functioning
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
automatic gearbox,
- position A on an electronic gear-
box or D on an automatic gearbox.
Steering wheel controls
The cruise control commands are
located on the left-hand side of the
steering wheel. The programmed information is
grouped together in zone
A of the
instrument panel display.

no cruise speed has
yet been memorised .
Programming
Rotate the control
1 to the "REG"
position.
Once the desired speed has been
reached via action on the accelera-
tor, press button 2 or button 4 . The
cruise speed is then memorised. It
is displayed in zone A of the instru-
ment panel. These actions cause
the information
"OFF"
to appear on the instru-
ment panel display.
These manoeuvres do
not cancel the cruise
speed which remains
displayed in the instru-
ment panel.
The cruise control cannot, in any
circumstances, take the place of

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
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
During the operation of cruise con-
trol, it is always possible to action
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),

PARKING SPACE SENSOR
System which measures the parking
space available between two vehicles
or obstacles. It measures the size of the
space and gives you information on:
- the possibility of fi tting into a free space, depending on the
dimensions of your vehicle and
the distances necessary for your
manoeuvring,
- the level of diffi culty of the ma- noeuvre to be performed.
The system does not measure spac-
es which are clearly much smaller or
larger than the size of the vehicle. Displays on the instrument
panel
The parking space sensor
function warning lamp can
have three different statuses:
- off: the function is not selected,
- on fi xed: the function is selected
but the conditions for measuring
are not yet met (direction indi-
cator not operating, speed too
high) or the measuring phase is
terminated.
- fl ashing: the measuring is in
progress or the message is being
displayed. You can select the "parking space
sensor" function by pressing button

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
deactivated:

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

 release the button when you
hear a beep. Deactivation is
confi rmed by the lighting of the
indicator 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 .

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding circuit checked by a
CITROËN dealer.
Oil level
Draining the engine
Refer to the servicing booklet for de-
tails of the interval for this operation. Oil specifi cation
The oil must correspond to your en-
gine and conform to the manufactur-
er's recommendations.
Brake fluid level
Draining the circuit
Refer to the servicing booklet for de-
tails of the interval for this operation.
This fl uid must be changed regularly.
Fluid which has been used exces-
sively may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and fulfi l the DOT4 standards.
Coolant level
Draining the circuit
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (approx. 1 000 km).
Check this level also between each
scheduled service and before long
journeys. The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
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 oper-
ate 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 en-
gine 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,
unscrew the cap by two turns to
allow the pressure to drop. When
the pressure has dropped, remove
the cap and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.
