Operation in manual mode

 Move the selector to position M .

Paddle controls
behind the steer-
ing 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 ac- cepted 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 op-
erates 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 on in
the instrument panel.
Do not use the accelerator to hold
your vehicle on a gradient. Use ei-
ther the brake pedal or the parking
brake.
Before doing anything in the en-
gine compartment, check that the
selector 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 se-
lect neutral or reverse gear, or to exit
reverse gear.
- If the vehicle stops or reduces speed (for example when ap-
proaching a stop sign), the gearbox
changes down automatically, to fi rst
gear if needed.

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 station-ary, 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 oc-
curs, 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
momentarily
when you re-
lease 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

momentarily
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 vehi-
cle with the engine running, manu-
ally 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 im-
prove driving in conditions of
poor grip,
- manual operation for sequen-
tial changing of the gears by the
driver. Mode selection

 Automatic mode: selector in po-
sition D .

 Sequential mode: selector in po-
sition 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 al-
lows 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 au- dible signal is heard if the se-
lector is not in position P ,
- always make sure that the se- lector is in position P before
you leave your vehicle.
If the gearbox is in position P but the
position of the selector is different,
reposition the selector on P so that
you can start the vehicle.

D R I V I N G

 Press the brake pedal.

 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.

 Gradually release the brake ped-
al 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 po-
sition (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 en-
gaging 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
following conditions:
- driving style,
- road profi le,
- vehicle load.
The gearbox is then operating in

auto-adaptive mode, without re-
quiring any action 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 accelera-
tor abruptly, the gearbox will not
change up.

 To exit position P , move the se-
lector 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.

SPORT and SNOW
programmes
These two special programmes sup-
plement the automatic operation in
very specifi c conditions of use.
Position of the selector for manual
gear changing.
The fl ashing of the warning 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.
Lighting of a dash in the rev coun-
ter 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 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 SPORT and SNOW modes
do not operate in sequential
mode.
SPORT programme "S"

 With the lever in position D and
the engine running, press but-
ton " S ".

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 (around 30 km/h) must be
programmed.
The speed limiter cannot, in any cir-
cumstances, take the place of the
observance of speed limits or of the
vigilance and responsibility of the
driver.
Steering wheel controls
The speed limiter controls are lo-
cated 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 "LIM" po-
sition.
On selection of the function, the
previous memorised speed and the
information "OFF" are displayed on
the instrument panel.
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
and a sustained press in steps of
3 mph. Activation
When the desired maximum speed
is displayed, press button
3 so that
the limitation is activated.
The information "OFF" then disappears from the instrument panel display.
While the function is active, pressing
the accelerator pedal will not enable
the programmed speed to be ex-
ceeded, 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.
Deactivation
Press on button 3 .
This action causes the information

"OFF" to appear on the instrument
panel display.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A of the
instrument panel.

D R I V I N G
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.
If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for exam-
ple 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. 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.
On a steep downhill gradient or on
sharp acceleration, the speed limiter
will not be able to prevent the vehi-
cle 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 functioning 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.

Deactivation

 Either by pressing on the brake
pedal or on 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.
These actions cause the information

"OFF" to appear on the instrument
panel display.
These actions do not cancel the
cruise speed which remains dis-
played in the instrument panel.
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 acce-
lerator pedal to return to the cruise
speed.
Return to normal driving

 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. Operating fault
If there is a malfunction, a message
will display accompanied by an
audible signal and lighting of the
service warning lamp.
Have it checked by a CITROËN
dealer.
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. 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.
