DRIVING
The Stop & Start system puts the en-
gine temporarily into standby - STOP
mode - during stops in the traffi c (red
lights, traffi c jams, or other...). The en-
gine restarts automatically - START
mode - as soon as you want to move
off. The restart takes place instantly,
quickly and silently.
Perfect for urban use, the Stop &
Start system reduces fuel consump-
tion and exhaust emissions as well
as the noise level when stationary.

Operation


Going into engine STOP mode

The "ECO"
warning lamp comes
on in the instrument panel and
the engine goes into standby:


- with the electronic gearbox
system
, at speeds below 4 mph
(6 km/h), press the brake pedal or
put the gear lever in position N
. If your vehicle is fi tted with the sys-
tem, a time counter calculates the
sum of the periods in STOP mode
during a journey. It rests itself to zero
every time the ignition is switched on
with the key.
Special cases: STOP mode not
available

Never refuel with the en-
gine in STOP mode; you
must switch off the ignition
with the key.
For your comfort, during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as
for example, braking, power steer-
ing... STOP mode is not invoked
when:


- the driver's door is open,

- the driver's seat belt is not fas-
tened,

- the vehicle has not exceeded
6 mph (10 km/h) since the last
engine start using the key,

- the electric parking brake is ap-
plied or being applied,

- the engine is needed to maintain
a comfortable temperature in the
passenger compartment,

- demisting is active,

- some special conditions (battery
charge, engine temperature,
braking assistance, ambient
temperature...) where the engine
is needed to assure control of a
system.
In this case, the "ECO"
warning
lamp fl ashes for a few seconds then
goes off.

This operation is perfectly normal.

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 pro-
grammed.
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 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, 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 obser-
vance 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 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.

(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

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
.
