DRIVING
Automatic operation
Position of the gear lever for
automatic gear changing. The gearbox is then operating in
auto-adaptive
mode, without requir-
ing any intervention on your part.
For certain manoeuvres (for exam-
ple overtaking), you can obtain max-
imum acceleration by pressing the
accelerator pedal down hard, which
then produces an automatic change
down to a lower gear.
When braking, the gearbox may
change down automatically in order
to provide effective engine braking.
If you lift your foot off the accelerator
abruptly, the gearbox will not change
up.
Temporary manual operation
when in automatic mode
)
Move the gear lever to position D
.
The gearbox constantly selects
the gear that is best suited to the
following conditions:
- driving style,
- road profi le,
- vehicle load.
At any time, operating the " +
" or " -
"
paddle allows you to exercise tem-
porary control over the gearbox. The
request to change gear will be taken
into account. You will still be in auto-
matic mode. The indicator D
remains
on in the instrument panel.
This function enables you to antici-
pate certain situations such as the
approach of a bend or the need to
overtake another vehicle.

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.

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
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 bum-
per, trigger a warning if the vehicle
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 this button, the indicator
lamp comes on.
Deactivation
)
Press this button again, the indi-
cator lamp goes 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 marking
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 in the screen.
Contact a CITROËN dealer or a
qualifi ed workshop.
The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility 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.

DRIVING
Front parking sensors
In addition to the rear parking sen-
sors, the front parking sensors are
triggered when an obstacle is detect-
ed in front and the speed of the ve-
hicle is still below 6 mph (10 km/h).
The front parking sensors are inter-
rupted if the vehicle stops for more
than three seconds in forward gear,
if no further obstacles are detected
or when the speed of the vehicle ex-
ceeds 6 mph (10 km/h).
The sound emitted by the speaker
(front or rear) indicates whether the
obstacle is in front or behind.
Deactivation/Activation of the
front and rear parking sensors
The function is deactivated by press-
ing this button. The indicator lamp in
the button comes on.
Pressing this button again reacti-
vates the function. The indicator
lamp in the button goes off.
The function will be deactivated au-
tomatically if a trailer is being towed
or a bicycle carrier is fi tted (vehicle
fi tted with a towbar or bicycle car-
rier recommended by CITROËN).
Operating fault
In the event of a malfunction
of the system, when reverse
gear is engaged this warn-
ing lamp is displayed in the
instrument panel and/or a message
appears in the screen, accompanied
by an audible signal (short beep).
Contact a CITROËN dealer or a
qualifi ed workshop.
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 moving at a
speed below 6 mph (10 km/h), cer-
tain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trig-
ger the audible signals of the park-
ing sensor system.

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
