left on multifunction screens A
and C and on the right on the
NaviDrive multifunction screen.
- A background-lit position grille as- sociated with the selector allows
you to view the position selected.

When the ignition is on,
lighting of the service
warning lamp, accompa-
nied by an audible signal and
the message "Gearbox faulty"
indicates a malfunction.
Consult a CITROËN dealer.
For safety:

 Position N can only be disen-
gaged if you are pressing the
brake pedal.

 If the gearbox is in position N
but the selector position is differ-
ent, reposition the selector on N
in order to be able to start. Moving off

 To start the engine, the selector
must be in position N .

 Press fi rmly on the brake pedal.

 Operate the starter.

 When the engine is running,
place the selector on R , A or M
as desired.

 Check, in the instrument panel,

Automatic operation

 Move the selector to po-
sition D . 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 maxi-
mum 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
The gearbox constantly selects the
gear that is best suited to the follow-
ing parameters:
- driving style,
- road profi le,
- vehicle load. An action on the "
+ " or " - " paddles
allows you to exercise temporary
control over the changing of gears.
The request to change gear will be
taken into account. You will still be
in automatic mode. The warning
lamp D remains lit up in the instru-
ment panel.
This function enables you to antici-
pate certain situations such as the
approach of a bend or the need to
overtake another vehicle.

gear changing.
 Move the selector to po-
sition M .
 Pull the " + " paddle to change up
a gear.

 Pull the " - " paddle to change
down a gear.
- If the vehicle stops or reduces speed (for example when ap-
proaching a stop sign), the gear-
box changes down automatically
to fi rst gear.
- In sequential mode, it is not nec- essary to release the accelerator
during gear changes.
- A request to change gear is ac- cepted only if the engine speed
permits it. - For safety reasons, depending
on the engine speed, a change
up or down may be performed
automatically.
- It is possible at any time to move from position D (driving in auto-
matic mode) to position M (driving
in sequential mode) or vice versa.
The fl ashing of the warn-
ing lamp for the position
requested signals that this
position is not yet obtained.
If the warning lamp is on fi xed, the
position is confi rmed.
Display of a dash in the rev counter
indicates a malfunction. Consult a
CITROËN dealer.
Lighting of the service warning
lamp accompanied by a message
and an audible signal indicates an
operating fault. In this case:
- a marked snatching may be felt when selecting R for reverse
gear,
- the gearbox is locked in one gear,
- do not exceed a speed of 60 mph (approx. 100 km/h).

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.

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 use 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),
then the speed fl ashes. Adapt your
speed as necessary.
Return to normal driving Operating fault

If there is a malfunction, a message will
display accompanied by an audible sig-
nal and lighting of the service warning
lamp.
Have it checked by a CITROËN
dealer.
Cruise control should only
be used when the driving
conditions allow you to drive
at a constant speed.
Do not use it in heavy traffi c,
or on dangerous or slippery roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to keep your
feet within range of the pedals.
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.

 By an action on the control 1 from
position "REG" to position 0 .

 By the engine stopping.
The cruise speed previously chosen is no longer memorised.

PARKING SPACE SENSOR
System which measures the parking
space available between two vehi-
cles or obstacles. It measures the
size of the space and gives you in-
formation 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 states:
- 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 be-
ing displayed. You can select the "parking space
sensor" function by pressing button
A.
The fi xed lighting of the warning lamp
indicates that the function is selected.

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
bumper, trigger a warning if the vehi-
cle 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 button A , the indicator
lamp comes on.
Deactivation

 Press button A again, the indicator
lamp switches 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 direc-
tion indicator is active and for approxi-
mately 20 seconds after the direction
indicator is switched off.
A warning may be transmitted if a direc-
tion 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 on the multifunction screen.
Consult a CITROËN dealer.
The lane departure warning system
cannot, in any circumstances, re-
place the need for vigilance and res-
ponsibility 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.

AUDIBLE AND/OR VISUAL REAR PARKING ASSISTANCE
System consisting of four proximity
sensors, located in the rear bumper.
This detects any obstacle (person,
vehicle, tree, gate, etc.) behind the
vehicle, except obstacles located
just below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the begin-
ning of the manoeuvre, but may no
longer be detected when the vehicle
comes close to it.
If there is an operating fault, when reverse gear is en-gaged this warning lamp comes on in the instrument panel, accompanied by an audible signal (short beep) and a message on the multifunction screen.
In bad or wintry weather, ensure that the sensors are not covered with mud, frost or snow.
Programming
You can activate or deactivate the system by means of the multifunc-tion screen confi guration menu. The system state is memorised when switching off the ignition.
For more information on access to the parking assistance menu, refer to the section on vehicle confi guration for your screen under "Multifunction screens".
The system will be deactivated auto-matically when towing a trailer or when a bicycle carrier is fi tted (vehi-cle fi tted with a towbar or bicycle car-rier recommended by CITROËN). cle fi tted with a towbar or bicycle car-cle fi tted with a towbar or bicycle car-
The parking assistance system cannot, in any circumstances, take the place of the vigilance and res-ponsibility of the driver.
Activation
The system is activated as soon as reverse gear is engaged, accompa-nied by an audible signal. The proxi-mity information is given by:
- an audible signal, which beco-mes more rapid as the vehicle approaches the obstacle,
- a graphic on the multifunction screen, with blocks which be-come increasingly closer to the vehicle.
When the distance between the rear of the vehicle and the obstacle is less than thirty centimetres, the audible signal becomes continuous and the "Danger" symbol appears on the multifunction screen.
On completion of the manoeuvre, when you exit reverse gear, the system becomes inactive.
