For optimum acceleration, for example
when over taking another vehicle, press the accelerator pedal firmly past the point of resistance.
Manual gear changing
This selective gear change mode enables you to over take, for example, while still remaining in automatic mode.  Operate the + or - steering mounted control paddle. The gearbox engages the gear requested if the engine speed permits. AUTO is still displayed in the instrument panel. After a few moments without any action on the controls, the gearbox resumes automatic control of the gears.
Manual mode
 After star ting the vehicle, select position Afor enter automatic mode.
Automatic mode
AUTO and the gear engaged appear in the instrument panel screen.
The gearbox is then operating in auto-active mode, without any action on the par t of the driver. It continuously selects the most suitable gear, depending on the: - style of driving, - profile of the road.
 When the vehicle has moved off, select position M to change to manual mode.
AUTO disappears and the gears engaged appear in succession in the instrument panel screen.
The gear change requests are only carried out if the engine speed permits. It is not necessary to release the accelerator during gear changes. When braking or slowing down, the gearbox changes down automatically to allow the vehicle to accelerate in the correct gear.
At very low speed, if reverse gear is requested, this will only be taken into account when the vehicle is immobilised. The Foot on brakewarning lamp may flash in the instrument panel to prompt you to brake.
On sharp acceleration, the gearbox will not change up unless the driver acts on the gear lever or the steering mounted paddles. Never select neutral N while the vehicle
is moving. Only engage reverse gear R when the vehicle is immobilised with the brake pedal pressed.

205Driving
System which keeps your vehicle immobilised temporarily (approximately 2 seconds) when star ting 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 stationary, with your foot on the brake pedal, - when certain conditions of gradient are met, - with the driver’s door closed. The hill star t assist function cannot be deactivated.
Hill start assist
On an ascending slope, with the vehicle stationar y, the vehicle is held for a brief moment when you release the brake pedal: - provided you are in first gear or neutral with a manual gearbox, - provided you are in position A or M with the electronic gearbox system.
Operation
Operating fault
If a fault occurs with the system, these warning lamps come on. Contact a CITROËN dealer or a qualified workshop to have the system checked.
Do not leave the vehicle while it is being held in the hill star t assist phase. If you need to leave the vehicle while the engine is running, apply the parking brake manually then ensure that the parking brake warning lamp is on (not flashing) in the instrument panel.
On a descending slope, with the vehicle stationar y and reverse gear engaged, the vehicle is held for a brief moment when you release the brake pedal.

Stop & Start The Stop & Star t system puts the engine temporarily on standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine restar ts automatically - START mode - as soon as y ou want to move off. The restar t takes place instantly, quickly and silently. Per fect for urban use, the Stop & Star t system reduce s fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
With the automatic gearbox system, for your comfor t during parking maoeuvres, STOP mode is not available for a few seconds after coming out of reverse gear. STOP mode does not affect the functionality of the vehicle, such as braking, power steering, for example.
Never refuel with the engine in STOP mode; you must switch off the ignition with the key.
The "ECO" warning lamp comes on in the instrument panel and the engine goes into standby:
- with a manual gearbox , at speeds below 12 mph (20 km/h), when you put the gear lever into neutral and release the clutch pedal, - with the 6-speed electronic gearbox system , at a speed below 5 mph (8 km/h),
when you press the brake pedal or put the gear lever into position N .
If your vehicle is fitted with the system, a time counter calculates the sum of the periods in STOP mode during a journey. It resets itself to zero every time the ignition is switched on with the key.
STOP mode is not invoked when: - the driver's door is open, - the driver's seat belt is not fastened, - the vehicle has not exceeded 6 mph (10 km/h) since the last engine start using the key, - the electric parking brake is applied or being applied, - the engine is needed to maintain a comfor table temperature in the passenger compar tment, - demisting is active, - some special conditions (battery charge, engine temperature, braking assistance, ambient temperature...) where the engine is needed to assure control of a system.
Special cases:STOP mode unavailable
In this case, the "ECO" warning lamp flashes for a few seconds, then goes off. This operation is per fectly normal.

at every new star t using the key.
Reactivation
This system requires a specific battery with a special specification and technology (reference numbers available from a CITROËN dealer or a qualified workshop). Fitting a battery not listed by CITROËN introduces the risk of malfunction of the system. In the event of a malfunction with the system, the "ECO OFF" switch warning lamp flashes, then comes on continuously. have it checked by a CITROËN dealer or a qualified workshop. In the event of a fault in STOP mode, the vehicle may stall. It is then necessary to switch off the ignition and star t the engine again using the key.
Operating fault Maintenance
Before working under the bonnet, deactivate the Stop & Star t system to avoid any risk of injury resulting from automatic operation of START mode.
The Stop & Star t system makes use of advanced technology. All work on this type of battery must be done only by a CITROËN dealer or a qualified workshop.
Press the "ECO OFF" switch again. The system is active again; this is confirmed
by the switch warning lamp going off and a message in the instrument panel.

Parking space sensors
System which measures the parking space available between two vehicles or obstacles. It measures the size of the space and gives you information on: - the possibility of fitting into a free space,
depending on the dimensions of your vehicle and the distances needed for manoeuvring, - the level of difficulty of the manoeuvre to be per formed. The system does not measure spaces which
are clearly much smaller or larger than the size of the vehicle.
Displays in the instrument panel You have identified a parking space:  Press button A to select the function.  Operate the direction indicator on the side where the space is to be measured; a message is displayed to confirm that measurement is in progress.  During measurement, go for ward the length of the space, at a speed less than 12 mph (approx. 20 km/h), to prepare for your manoeuvre.  Once the measurement has been completed, the system informs you of the level of difficulty of the manoeuvre by a message in the multifunction screen
accompanied by an audible signal.
Operation
The parking space sensor function warning lamp can have two different states:
- on fixed: the function is selected by a press on control A . - off: the function is not selected,

Front parking sensors Operating fault
If an operating fault occurs, when reverse gear is engaged this warning lamp is displayed in the
instrument panel and/or a message appears in the screen, accompanied by an audible signal (shor t beep). Contact a CITROËN dealer or a qualified workshop.
In addition to the rear parking sensors, the front parking sensors are triggered when an obstacle is detected in front and the speed of the vehicle
is still below 6 mph (10 km/h). The sound emitted by the speaker (front or rear) indicates whether the obstacle is in front or behind. The front parking sensors are interrupted if the vehicle stops for more than three seconds in for ward gear, if no fur ther obstacles are detected or when the speed of the vehicle exceeds 6 mph (10 km/h).
The function will be deactivated automatically if a trailer is being towed or a bicycle carrier is fitted (vehicle fitted with a towbar or bicycle carrier recommended by CITROËN).
In bad weather or in winter, ensure that the sensors are not covered with mud, ice or snow. When reverse gear is engaged, an audible signal (long beep) indicates that the sensors may be dir ty. When the vehicle is moving at a speed below 6 mph (10 km/h), cer tain sound sources (motorcycle, lorry, pneumatic drill, etc.) may trigger the audible signals of the parking sensor system.
Deactivation/Activation of the front and rear parking sensors
The function is deactivated by pressing this button. The indicator lamp in the button
comes on. Pressing this button again reactivates the function. The indicator lamp in the button goes off.
