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.

Blind spot sensors
This driving assistance system warns the driver of the presence of another vehicle in the blind spot angle of their vehicle, as soon as this presents a potential danger.
Operation
This system is designed to improve safety when driving and is in no circumstances a substitute for the use of the interior rear view mirror and door mirrors. It is the driver's responsibility to constantly check the traffic, to ass es the distances and relative speeds of other vehicles and to predict their movements before de ciding whether to change lane. The blind spot sensor system can never replace the vigilance and responsibility of the driver.
 On switching on the ignition, or engine running, press this button to activate the function; the warning lamp comes on.
Sensors fitted in the front and rear bumpers monitor obscured zones in the driver's field of vision.
A warning lamp appears in the door mirror on the side in question: - immediately, when being over taken, - after a delay of one second, when over taking another vehicle too slowly.

Operating fault
In the event of a fault, the warning lamp in the button flashes then goes off. Have it checked by a CITROËN dealer or a qualified workshop.
The system may suffer temporary inter ference in cer tain weather conditions (rain, hail...). In par ticular, driving on a wet sur face or moving from a dry area to a wet area can cause false aler ts (the presence of a fog of water droplets in the blind spot angle is interpreted as a vehicle). In bad or wintry weather, ensure that the sensors are not covered by mud, ice or snow. Take care not to cover the warning zone in the door mirrors with adhesive labels or other objects. Do not stick labels or attach objects
to the front and rear bumpers; they may hamper the correct operation of the system.
 To deactivate the system, press this button again; the warning lamp goes off. The state of the system remains in memory on switching off the ignition.
The system is automatically deactivated when towing with a towbar approved by CITROËN.

213Driving
System which prevents the vehicle from exceeding the speed programmed by the driver. When the programmed speed limit is reached, pressing the accelerator pedal no longer has any effect.
Speed limiter
The speed limiter cannot, in any circumstances, replace the need to respect speed limits, nor can it replace the need for vigilance and responsibility on the par t of the driver.
The functions of this system are grouped together on the steering mounted controls. 1. Speed limiter mode selection dial. 2. Programmed value decrease button. 3. Programmed value increase button. 4. Speed limiter on/off button. 5. List of memorised speeds display button. (see "Memorising speeds")
Steering mounted controls
The programmed information is grouped together in the instrument panel screen. 6. Speed limiter on/off indication. 7. Speed limiter mode selection indication. 8. Programmed speed value. 9. Selection of a memorised speed. (see "Memorising speeds")
Displays in the instrument panel
Operation
The speed limiter is switched on manually: it requires a programmed speed of at least20 mph (30 km/h). The speed limiter is switched off by manual d offoperation of the control. The programmed speed can be exceeded temporarily by pressing the accelerator firmly beyond the point of resistance. To return to the programmed speed, simply release the accelerator pedal. The programmed speed remains in the memory when the ignition is switched off.

215Driving
Cruise control
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal.
The functions of this system are grouped together on the steering mounted controls. 1. Cruise control mode selection dial. 2. Speed programming/value decrease button. 3. Speed programming/value increase button. 4. Cruise control off/resume button. 5. Stored speeds display button. (see "Storing speeds")
Steering mounted controls
The cruise control system cannot, in any circumstances, replace the need to respect speed limits, nor can it replace the need for vigilance and responsibility on the par t of the driver. You are advised to keep your feet near the pedals at all times.
The programmed information is grouped together in the instrument panel screen. 6. Cruise control off/resume indication. 7. Cruise control mode selection indication. 8. Programmed speed value. 9. Selecting a stored speed. (see "Storing speeds")
Displays in the instrument panel
Operation
The cruise control is switched on manually: it requires a minimum vehicle speed of 25 mph (40 km/h) and engagement of: - four th gear on the manual gearbox, - second gear on the electronic gearbox system, in sequential driving mode, - position A on the electronic gearbox system. The cruise control is switched off manually d offor by pressing the brake or clutch pedal or on triggering of the ESP system for safety reasons. It is possible to exceed the programmed speed temporarily by pressing the accelerator pedal. To return to the programmed speed, simply
release the accelerator pedal. Switching off the ignition cancels any programmed speed value.

The function displays the following types of message: The function deselects itself automatically: - when you engage reverse gear, - when you switch off the ignition, - if measuring is not requested,
- within five minutes of selection of the function, - if the vehicle speed exceeds the threshold of 45 mph (approx. 70 km/h) for one minute.
If the lateral distance between your vehicle and the parking space is too large, the system may not be able to measure the space.
The system remains available after each measurement and can therefore measure several spaces in succession. In poor or wintry weather, ensure that the
sensors are free of dir t, ice or snow. The parking space sensor system deactivates the front parking sensors when measuring for wards.
Parking possible
Parking difficult
Parking not advised
If there is a fault, have the system checked by a CITROËN dealer or a qualified workshop.

229Checks
Checking levels
Check all of these levels regularly and top them up if necessary, unless other wise indicated. If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified wo rkshop.
Oil level
Engine oil change
Refer to the Maintenance and Warranty Guide for the inter val for this operation.
In order to maintain the reliability of the engine and emission control system, the use of additives in the engine oil is prohibited.
Oil specifi cation
The oil must correspond to your engine and conform to the manufacturer's recommendations.
Brake fluid level
Changing the fl uid
Refer to the Maintenance and Warranty Guide for the inter val for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations and meet the DOT4 standard.
The brake fluid level should be close to the "MA X" mark. If it is not, check the brake pad wear.
The reading will only be correct if the vehicle is on level ground and the engine has been off for more than30 minutes. The check is carried out either when the ignition is switched on using the oil level indicator in the instrument panel, or using the dipstick.
When working under the bonnet, take care, as cer tain areas of the engine may be extremely hot (risk of burns).

Changing the coolant
The coolant does not have to be changed.
Coolant specifi cation
The coolant must conform to the manufacturer's recommendations.
Coolant level
The coolant level should be close to the "MA X" mark but should never exceed it. When the engine is warm, the temperature of the coolant is regulated by the fan. This can operate with the ignition off. On vehicles which are fitted with a par ticle
emission filter, the fan may operate after the vehicle has been switched off, even if the engine is cold.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out any work. To avoid any risk of scalding, unscrew the cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and top up the level.
Power steering fluid level
The power steering fluid level should be close to the "MA X" mark. Unscrew the cap, with the engine cold, to check the level.
To check the level or top up the fluid, immobilise the vehicle and switch of the engine.
