Neutral
If the vehicle is moving, do not select this position, even momentarily.
Reverse gear
Only engage reverse gear when the vehicle is stationary.
If the vehicle is moving at a very low speed, if reverse gear is requested (position R) this will be taken into account only when the vehicle comes to a halt.
The "foot on brake" warning lamp may fl ash in the instrument panel to remind you to brake.
If the vehicle is moving at a high speed, if reverse gear is requested the warning lamp "N" will fl ash and your vehicle will go automatically into neutral. To re-engage a gear, you have only to return the gear lever to position A or M.
A sound signal indicates when reverse gear is engaged.
If parking assistance is deacti-vated, the sound signal for reverse gear engaged is absent.
The engine can only be started if the brake pedal is pressed and the gear lever is in position N.
The warning lamp "foot on brake" fl ashes on the display.
With the engine running, before accelerating away check the position engaged by looking at the lever grille or the rev counter : R, A or M.
If you are stationary with the engine running, take care to leave your gear selector in position N.

Starting the vehicle
- To start the engine, the gear lever has to be in position N.
- Fully depress the brake pedal.
- Action the starter.
- With the engine running, depend-ing on your preference place the lever on R, A or M.
- Check the position engaged on the rev counter.
- Release the handbrake.
- Release the brake pedal and accelerate.
If the lever is not in position N, the warning lamp "N" fl ashes on the rev counter.
If the brake pedal is not pressed down, the warning lamp "Foot on brake" fl ashes in the instrument panel.
In both cases, the engine does not start; recommence the above proce-dure.
Note: If the vehicle has been sta-tionary for a long time, or if you have pressed the brake pedal a number of times while stationary, it will be necessary to press the brake pedal hard down in order to authorise the engine to start.
Stopping the engine
Before switching the engine off, you can choose:
- to leave the vehicle in neutral; for that, place the lever in position N,
- to leave the vehicle with a gear engaged (R, A or M); for that, place the lever in the position cho-sen. In this case, the vehicle can-not be moved.
In all cases, it is essential to apply the handbrake.
Before undertaking any operation in the engine compartment, make absolutely sure that the gearbox is in neutral and that the handbrake is on.
Do not hold the vehicle stationary using only the accelerator.
If you are stopped on an incline, use the handbrake to hold the vehicle.
Acceleration
To obtain optimum acceleration (for example to overtake another vehi-cle), you have only to press the pedal hard down to go beyond the end-of-travel switch.

Manual mode
Position the gear lever in position M, then:
- push the lever to engage a higher gear,
- pull the lever to change down.
Manual mode with controls behind the steering wheel
Place the gear lever in position M, and then the controls at the steering wheel will give you access to the six gears in forward drive.
To change gear:
- Press behind the control "+" at the steering wheel to engage a higher gear.
- Press behind the control "-" at the steering wheel to change down.
Observations:
When the vehicle is braking or reduc-ing speed, the gearbox changes down automatically to a suitable gear.
In manual mode, it is not necessary to release the accelerator during changes of gear.
Changes of gear are accepted only if consistent with engine speed.
Under heavy accelera-tion, a higher gear will only be engaged when the driver actions the gear lever or the controls at the steering wheel.
Note: These controls at the steering do not permit you to select neutral or reverse gear.

Drive
The gearbox always selects the gear best adapted to the following param-eters:
- style of driving,
- route profi le,
- vehicle load.
In this way the gearbox operates in autoadaptive mode, without the need for your intervention.
For certain manoeuvres (for example overtaking), it is possible to ob tain maxi-mum acceleration by pressing hard down on the accelerator pedal, which may trigger automatic changedown to a lower gear.
Note
During braking, the gearbox may kick down automatically in order t o offer an effective engine brake.
If you rapidly lift your foot off the accelerator, the gearbox will guard your safety by not changing up again.
Sequential forward drive
Selector position for manual gear changing.
- Selector at M.
- Push the selector towards the sign "+" to change up a gear.
- Pull the selector towards the sign "-" to change down a gear.
Note: Passage from one gear to another is only possible when vehicle speed and engine speed permit.
The Sport and Snow programmes are not operative in sequential mode.
The change from position D (drive in automatic mode) to position M (drive in sequential mode) or vice versa may be effected at any time.

Do not engage until the vehicle is completely stationary.
To avoid any movement of the vehi-cle when parked, select positionP and apply the handbrake fi rmly. Check that the selector is in the Pposition to ensure that the driving wheels are locked.
Reverse gear
Do not engage until the vehicle is stationary, foot on brake. To avoid engine hesitation, do not accelerate immediately after the selection.

- Or when ESP or ASR is active.
Note: cruise control is disengaged when the gear lever is in neutral position.
These actions bring up the display "OFF" in zone A in the instrument panel.
These actions do not cancel your cruise speed which remains dis-played on the instrument panel.
Cruise control must only be used where road conditions permit driving at a constant speed.
Do not use it on congested roads or when weather and road conditions are poor.
The driver must still remain attentive and in complete con-trol of the vehicle.
You are recommended to keep your feet within range of the pedals.To avoid any interference with the pedals:To avoid any To avoid any

This driving assistance device allows you to select a maximum speed that you wish not to exceed. This has to be a speed greater than 30 km/h (approx. 20 mph).
The speed limiter controls are located on the steering wheel.
Note: The information relating to the limiter is displayed in zone A of the instrument panel.
To select the function
Turn control 1 to position "LIM".
On selection of the function, the last speed memorised and the informa-tion "OFF" will appear:
To adjust the maximum speed
Provided the engine is running, you can adjust the memorised maximum speed, with short or long presses on:
- button 4 to increase the memo-rised maximum speed,
- button 2 to decrease the memo-rised maximum speed.
Note: successive presses modify the memorised speed in steps of 1 km/h (1 mph), a continuous press in steps of 5 km/h (3 mph).
Activation of the maximum speed
When the desired maximum speed is displayed, press button 3 to acti-vate the limitation.
The information "OFF" then disap-pears from zone A.
While the function is active, pressing the accelerator pedal will not enable you to go beyond the programmed speed unless you press the pedal hard down past the tight spot (see "Temporary exceeding of the maxi-mum speed").

To stop the function
- move the control from position "LIM" to position 0.
- or stop the engine.
The speed that you chose is memo-rised.
In the event of a malfunction, a message is displayed, accompanied by a sound signal and lighting of the SERVICE warning lamp.
Consult your CITROËN dealer.
A fl oor mat not recom-mended by CITROËN risks sliding under the accelerator pedal, thus preventing you from pressing past the tight spot.
It will then be impossible to exit from the desired limitation, unless by acting on the steer-ing wheel control.
The driver must still remain atten-tive and in complete control of the vehicle.
We advise the driver to keep their feet close to the pedals.
Note: if during speed limitation, the system cannot keep to the maxi-mum speed (especially on a steep descent or if you accelerate too hard) the speed fl ashes. Adapt your speed as necessary.
The function will re-engage when your speed has returned below the desired maximum.
Deactivation of the maximum speed
Press button 3.
The information "OFF" will appear on the instrument panel screen.
This action does not cancel the memorised maximum speed, which remains displayed in zone A of the instrument panel.
Temporary override of the maximum speed
You can exceed the memorised maximum speed at any time by pressing the accelerator pedal hard down past the tight spot.
During the time the limit speed is being exceeded, the displayed speed fl ashes.
You have only to release the accel-erator pedal to return below the maximum speed, thus keeping the function active.
