Operation in manual mode

 Move the selector to po-
sition M .

Paddle controls
behind the steering
wheel
The paddles behind the steering
wheel give you access to the six for-
ward gears. 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 gear-
box changes down automatically,
to fi rst gear if needed.
- 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 automatically.
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 on in
the instrument panel.
Do not use the accelera-
tor to hold your vehicle on
a gradient. Use either the
brake pedal or the parking
brake.
Before doing anything in the en-
gine compartment, check that the
selector is in neutral N .

 To start the engine, press the
brake pedal and place the selec-
tor in position P .

 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 ac-
celerate.

 If the selector is not in position P ,
a message "place automatic
gearbox in position P " appears
on the multifunction screen, ac-
companied by a beep and the
fl ashing of P on the instrument
panel.
Moving off

 To avoid incoherence between
the position of the selector and
the actual position of the gear-
box, always exit from position P
when you switch on the ignition
and press the brake pedal.
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.
Park

 To select position P, move the
selector back to the highest po-
sition (towards R ), then push it
forwards and then to the left.

 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 po-
sitioned. Reverse gear
Neutral
Only engage this position
when the vehicle is station-
ary. To prevent snatching,
do not accelerate too soon
after selection.
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 .
This position of the selector
is used to prevent the vehi-
cle from moving when you
are stationary.

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.

Manual operation
Position of the selector for manual
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).
Consult a CITROËN dealer.

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 pro-
grammed.
The speed limiter controls are located
on the left-hand side of the steering
wheel. The programmed information is
grouped together in zone
A of the
instrument panel display.
Steering wheel controls
Displays on 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
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.
On selection of the
function, the previous
memorised speed and
the information "OFF"
are displayed on the
instrument panel. 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 memorised.
The speed limiter cannot, in any circum-
stances, take the place of the observ-
ance of speed limits or of the vigilance
and responsibility of the driver.

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 au-
dible signal and lighting of the serv-
ice 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.

RUNNING OUT OF FUEL (DIESEL)
HDi 138 engine
Detach the protective cover for access
to the priming pump. HDi 110 engine
Detach the protective cover for access
to the priming pump. Priming the fuel circuit
In the event of running out of fuel:

 after fi lling (minimum 5 litres),
squeeze the manual priming
pump repeatedly, until some re-
sistance is felt,

 then operate the starter, gently
pressing the accelerator until the
engine starts.
If the engine fails to start at the fi rst
attempt, wait 15 seconds before
trying again.
If the engine fails to start after a few
attempts, repeat the procedure from
the beginning. When the engine is
idling, accelerate gently to complete
the purge of the circuit.
HDi engines are of a highly
technical nature.
All maintenance and re-
pairs require specifi c qualifi cations
which only your CITROËN dealer
can guarantee.
