Automatic operation
 Select position D for automatic changing of the four gears. The gearbox then operates in auto-adaptive mode, without any inter vention on the par t of the driver. It continuously selects the most suitable gear according to the style of driving, the profile of the road and the load in the vehicle. For maximum acceleration without touching the lever, press the accelerator pedal down fully (kick down). The gearbox changes down automatically or maintains the gear selected until the maximum engine speed is reached. On braking, the gearbox changes down automatically to provide efficient engine braking. If you release the accelerator sharply, the gearbox will not change to a higher gear for safety reasons.
Never select position N while the vehicle is moving. Never select positions P or R unless the vehicle is completely stationary.
Sport and snow
programmes
These two special programmes supplement the automatic operation in very specific conditions of use.
Sport programme "S"
 Press button "S" , after star ting the engine. The gearbox automatically favours a dynamic style of driving.
S appears on the instrument panel.
Snow programme "  "
 Press button "  ", after star ting the engine. The gearbox adapts to driving on slippery roads. This programme improves star ting and drive when traction is poor.
 appears on the instrument panel.
Return to automatic
operation
 At any time, press the button selected again to quit the programme engaged and return to auto-adaptive mode.

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.

Checks
Battery
Air filter and passenger compartment filter
Oil filter
Particle emission filter
(Diesel)
It is imperative that the maintenance of the par ticle emission filter is carried out by a CITROËN dealer.
Following prolonged operation of the vehicle at very low speed or at idle, you may, in exceptional circumstances, notice the emission of water vapour at
the exhaust on acceleration. This does not affect the behaviour of the vehicle or the environment.
Unless other wise indicated, check these components in accordance with the Maintenance and Waranty Guide a nd according to your engine. Other wise, have them checked by a CITROËN dealer.
The battery does not require any maintenance. However, check that the terminals are clean and correctly tightened, particularly in summer and winter. When carrying out work on the battery, refer to the "Practical information" section for details of the precautions to be taken before disconnecting the battery and following its reconnection.
Refer to the Maintenance and Warranty Guide for details of the replacement inter vals for these components. Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessar y (refer to the "Engines" paragraph). A clogged passenger compar tment filter may have an adverse effect on the per formance of the air conditioning system and generate undesirable odours.
Replace the oil filter each time the engine oil is changed. Refer to the Maintenance and Warranty Guide for details of the replacement interval for this component.
