Operation in manual mode

 Move the selector to position M .

Controls
behind
the steering wheel
The paddles behind the steering
wheel give you access to the six for-
ward gears. - In manual mode, it is not neces-
sary to release the accelerator
completely during gear changes.
- A request to change gear is accepted only if the engine
speed permits it.
- For safety reasons, depending on the engine speed, a change
down may be performed auto-
matically.
In situations of high engine speeds
(heavy acceleration), a change
up will not occur unless the driver
operates the paddle.
Acceleration
For optimum acceleration (e.g. to
overtake another vehicle), simply
press the pedal beyond the point of
resistance at the end of its travel, by
pressing down fi rmly.
Vehicle stationary, with the
engine running
In the event of a prolonged stop with
the engine running, the gearbox
changes automatically to neutral N . Stopping the vehicle
Before stopping the engine, you can
choose:

 to leave the vehicle in neutral;
move the selector to position N .

 to leave the vehicle with a gear
engaged ( R , A or M ); place the
selector in the chosen position
prior to stopping the engine. In
this case, the vehicle cannot be
moved.
In all cases, it is essential to apply
the parking brake. Check that the
parking brake warning lamp is lit up
in the instrument panel.
Do not use the accelerator to hold
your vehicle on a gradient. Use
either the brake pedal or the parking
brake.
Before doing anything in the engine
compartment, check that the selec-
tor is in neutral N .
Changing gear

 Pull the " +
" paddle to change up
a gear.

 Pull the " -
" paddle to change
down a gear.
The paddles do not permit you to
select neutral or reverse gear, or to
exit reverse gear.
- If the vehicle stops or reduces speed (for example when
approaching a stop sign), the
gearbox changes down auto-
matically, to fi rst gear if needed.

D R I V I N G
HILL START ASSIST (WITH THE 6-SPEED ELECTRONIC GEARBOX SYSTEM)
System which holds your vehicle tem-
porarily (approximately 2 seconds)
when starting on a gradient, the time it
takes to move your foot from the brake
pedal to the accelerator pedal.
This function is only active when:
- the vehicle is completely stationary, with your foot on the brake pedal,
- in particular conditions on a slope,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation
Operating fault
If a malfunction of the system
occurs, these warning lamps come
on. Contact a CITROËN dealer to
have the system checked.

On an ascending slope, with the
vehicle stationary, the vehicle is
held for a brief moment when you
release the brake pedal:
- provided you are in A or M on an
electronic gearbox,
On a descending slope, with the
vehicle stationary and reverse
gear engaged, the vehicle is held
for a brief moment when you
release the brake pedal.
do not exit the vehicle while
it is being held in the hill
start assist phase.
If you need to exit the vehicle with
the engine running, manually apply
the parking brake and ensure that
the warning lamp P (red) on the
instrument panel is permanently on.

AUTOMATIC GEARBOX
Automatic gearbox which offers a
choice between the comfort of fully
automatic operation, enhanced by
the sport and snow programmes, or
manual gear changing.
Therefore, you have a choice of four
driving modes:
- automatic operation for elec-
tronic control of the gears by the
gearbox,
- the SPORT programme for a
more dynamic style of driving,
- the SNOW programme to improve
driving in conditions of poor grip,
- manual operation for sequen-
tial changing of the gears by the
driver. Mode selection

 automatic mode: selector in posi-
tion D ,

 sequential mode: selector in posi-
tion M ,

 SPORT mode: selector in posi-
tion D with button S pressed,

 SNOW mode: selector in posi-
tion D with button "  " pressed.
Displays on the instrument
panel
The position of the gear selector is
displayed on the instrument panel.
A position grille on the selector
allows you to view the position that
is selected.

 To start the engine, the selector
has to be in position P or N .
For safety:
- position
P can be disengaged
only if you press the brake pedal,
- when a door is opened, an audible signal is heard if the
selector is not in position P ,
- always make sure that the selector is in position P before
you leave your vehicle.
If the gearbox is in position P but
the position of the selector is diffe-
rent, reposition the selector on P
so that you can start the vehicle.
Moving off

D R I V I N G

 Operate the starter.

 When the engine is running,
place the selector on R , D or M
as required.

 Check, in the instrument panel,
the position engaged.

 Release the brake pedal and
accelerate.

 To avoid a difference between
the position of the selector and
the actual position of the gear-
box, only exit from position P
with the ignition on and the brake
pedal pressed.
Park Reverse gear
This position of the selector is used
to prevent the vehicle from moving
when you are stationary.

 To select position P, move the
selector back to the highest
position (towards R ), then push it
forwards and then to the left. Only engage this position when
the vehicle is stationary. To prevent
snatching, do not accelerate too
soon after selection.
Neutral
Never select position N if the vehicle
is moving.
Never select positions P or

R if the vehicle is not sta-
tionary.
If, while the vehicle is moving, po-
sition N is engaged inadvertently,
allow the engine to idle before
engaging position D or M .
Otherwise, when the ignition is on or
the engine is running:

 reposition the selector in position P ,

 put your foot on the brake pedal
and then select the gear you
want. Automatic operation

 Move the selector to position D .
The gearbox constantly selects the
gear that is best suited to the follo-
wing conditions: - driving style,
- road profi le,
- vehicle load.
The gearbox is then operating in

auto-adaptive mode, without requi-
ring any action on your part.
For certain manoeuvres (for example
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 accelera-
tor abruptly, the gearbox will not
engage a higher gear.

 To exit position P , move the
selector to the right and then to
the position you want.

 Only engage this position when
the vehicle is completely sta-
tionary. In this position, the front
wheels are locked. Make sure
that the selector is correctly posi-
tioned.

indicates an operating fault. In this
case:
- a marked snatching may be felt
when selecting R for reverse
gear,
- the gearbox is locked in a gear,
- do not exceed 60 mph (approx. 100 km/h).
Consult a CITROËN dealer.
- A request to change gear is
accepted 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 (dri-
ving in sequential mode) or vice
versa.

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
gearbox or D on an automatic
gearbox.
The cruise control cannot, in any
circumstances, take the place of the
observance of speed limits or of the
vigilance and responsibility of the
driver. Steering wheel controls
The cruise control switches are
located on the left-hand side of the
steering wheel.
Displays on the instrument panel
The programmed information is
grouped together in zone
A of the
instrument panel display. Programming
Rotate the control
1 to the "REG"
position.
Activation
On selection of the function via con-
trol 1, no cruise speed has yet
been memorised.
Once the desired speed has been
reached using the accelerator, press
button 2 or button 4 . The cruise
speed is then memorised. It is dis-
played in zone A of the instrument
panel.
You can then release the accelera-
tor pedal. The vehicle will automati-
cally keep to the speed chosen.
The speed of your vehicle may vary
slightly in relation to that memo-
rised.
You can adjust the memorised speed
on the instrument panel display by
pressing on:

 button 4 to increase the speed,

 button 2 to decrease the speed.
Successive presses modify the
cruise speed in steps of 1 mph and a
sustained press in steps of 3 mph.

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.

The gearbox does not re-
quire any maintenance (no
oil change).
6-speed electronic gearbox
system The gearbox does not re-
quire any maintenance (no
oil change).
Automatic gearbox The gearbox does not re-
quire any maintenance (no
oil change). Brake disc wear status
For information relating to
checking the brake disc wear
status, contact a CITROËN
dealer.
Handbrake If the handbrake travel is
too long or if a loss of ef-
fectiveness of this system
is noticed, the handbrake
must be adjusted, even
between two services.
