Front parking sensors

In addition to the rear parking sensors,
the front parking sensors are triggered
when an obstacle is detected in front
and the speed of the vehicle is still be-
low 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 parking
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
by the extinction of the indicator
lamp in button B
.

PRACTICAL INFORMATION












Removing a wheel



)
Park the vehicle on level, stable
and non-slippery ground. Apply
the parking brake (a message
and a warning lamp appear in
the instrument panel).
Switch off the ignition and en-
gage fi rst gear or reverse gear
depending on the slope (position
P
if an automatic gearbox, D
or
R
if a 6-speed electronic gear-
box).

)
Use a chock to secure the vehi-
cle more safely. Place the chock
9
in front of the wheel opposite
the punctured wheel.
)
Detach the trim using the remov-
ing tool 4
, pulling in the area of
the valve.
For vehicles with alloy wheels,
insert the trim removing tool 1

into the recess in the central trim
and lever it off.
For vehicles with alloy wheels
that have visible bolts, remove
the chrome covers using the re-
moving tool 2
.
)
Slacken the wheel bolts. For ve-
hicles with alloy wheels, slacken
the security bolts using the secu-
rity bolt socket 6
.

)
Position the jack under the vehi-
cle, at the jacking point A
closest
to the wheel to be changed.

)
Unwind the jack 5
until its brack-
et is in contact with the ground.
Make sure that the jack is verti-
cal under the jacking point used.

)
Continue to extend the jack so
as to raise the vehicle.

)
Undo the wheel bolts and re-
move the wheel.

Before any operation of this
sort, it is advisable to deactivate
your pneumatic suspension.

PRACTICAL INFORMATION

Towbar suitable for the attachment
of a trailer with additional lighting
and signalling.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to
a CITROËN dealer or a qualifi ed
workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted in accordance with the
vehicle manufacturer's instructions.

Driving advice


Distribution of loads


)
Distribute the load in the trailer
so that the heaviest items are as
close as possible to the axle and
the nose weight approaches the
maximum permitted without ex-
ceeding it.
Air density decreases with altitude,
thus reducing engine performance.
Above 1 000 metres, the maximum
towed load must be reduced by 10 %
for every 1 000 metres of altitude.
Refer to the "Technical Data" section
for details of the weights and towed
loads which apply to your vehicle.

Side wind


)
Take into account the increased
sensitivity to side wind.


)
To lower the engine speed, re-
duce your speed.
The maximum towed load on a long
incline depends on the gradient and
the ambient temperature.
In all cases, keep a check on the
coolant temperature.


)
If the warning lamp and
the STOP
warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.


Braking
Towing a trailer increases the brak-
ing distance.
To avoid overheating of the brakes
on a long mountain type of descent,
the use of engine braking is recom-
mended.

Tyres


)
Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.


Lighting


)
Check the electrical lighting and
signalling on the trailer.
The rear parking sensors will be
deactivated automatically if a gen-
uine CITROËN towbar is used.
Driving with a trailer places greater
demands on the towing vehicle and
the driver must take particular care.

Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled,
its cooling capacity is not dependent
on the engine speed.
