Four-speed automatic gearbox which offers a choice between the comfor t of fully automatic operation, enhanced by spor t and snow programmes, or manual gear changing. Therefore, four driving modes are offered:
- automatic operation for electronic management of the gears by the gearbox, - spor t programme for a more dynamic style of driving, - snow programme to improve driving when traction is poor, - manual operation for sequential changing of the gears by the driver.
Automatic gearbox

Displays on the instrument panel
Foot on brake
Press the brake pedal when this indicator lamp is displayed on the instrument panel (e.g.: star ting the engine).
Moving off
If position N is engaged inadver tently while driving, allow the engine to return to idle then engage position D to accelerate.
When the engine is running at idle, with the brakes released, if position R ,
D or M is selected, the vehicle moves even without the accelerator being pressed. When the engine is running, never leave children in the vehicle without super vision. When carrying out maintenance with the engine running, apply the parking brake and select position P . PP
 Apply the parking brake.  Select position P or N .  Star t the engine. If this procedure is not followed, an audible signal is heard, accompanied by a message on the multifunction screen.  With the engine running, press the brake pedal.  Release the parking brake.  Select position R , D or M ,  Gradually release the brake pedal. The vehicle moves off immediately.

Manual operation
D disappears and the gears engaged appear in succession on the instrument panel. In the event of the engine labouring or over-revving, the gear selected flashes for a few seconds, then the actual gear engaged is displayed.
It is possible to change from position D(automatic) to position M (manual) at any time. When the vehicle is stationary or moving very slowly, the gearbox selects gear M1automatically. The spor t and snow programmes do not operate in manual mode.
Invalid value during manual operation
 Select position M for sequential changing of the four gears.  Push the lever towards the + sign to change up a gear.  Pull the lever towards the - sign to change down a gear. It is only possible to change from one gear to another if the vehicle speed and engine speed permit; other wise, the gearbox will operate temporarily in automatic mode.
This symbol is displayed if a gear is not engaged correctly (selector between two positions).
Stopping the vehicle
Before switching off the engine, you can engage position P or N to place the gearbox in neutral. In both cases, apply the parking brake to immobilise the vehicle.
When the ignition is on, the lighting of this warning lamp, accompanied by an audible signal and a message on the multifunction screen, indicates a gearbox malfunction. In this case, the gearbox switches to back-up mode and is locked in 3rd gear. You may feel a substantial knock when changing from P to R RRand from N to R . This will not cause any damage to the gearbox. Do not exceed 60 mph (100 km/h), local speed restrictions permitting. Contact a CITROËN dealer as soon as possible.
Operating fault
If the lever is not in position P , Pwhen the driver's door is opened or approximately 45 seconds after the ignition is switched off, a message appears in the multifunction screen.  Return the lever to position P ; the
message disappears.
There is a risk of damage to the gearbox:
- if you press the accelerator and brake pedals at the same time, - if you force the movement of the gear
lever from the P position to another position when the battery is flat.
To reduce fuel consumption when at a prolonged standstill with the engine running (traffic jam...), put the gear lever in the N position and apply the parking brake.

Brake pads
Brake wear depends on the style of driving, par ticularly in the case of vehicles used in town, over shor t distances. It may be necessary to have the condition of the brakes checked, even between vehicle ser vices. Unless there is a leak in the circuit, a drop in the brake fluid level indicates that the brake pads are worn.
The gearbox does not require any maintenance (no oil change). Refer to the Maintenance and Warranty Guide for the details of the level checking inter val for this component.
Brake disc wear
