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.

Electric parking brake
This system does not require any routine ser vicing. However, in the event of a problem, have the system checked by a CITROËN dealer or a qualified workshop. For more information, see "Driving - Electric parking brake - § Operating faults".
Only use products recommended by CITROËN or products of equivalent quality and specification. In order to optimise the operation of units as impor tant as the braking system, CITROËN selects and offers very specific products. To avoid damaging the electrical units, the use of a high pressure washer in the engine compar tment is strictly prohibited . Brake disc wear
For information on checking brake disc wear, contact a CITROËN dealer or a qualified workshop.
Manual parking brake
If a loss of effectiveness of this system is noticed, the parking brake must be checked, even between two ser vices. Checking this system must be done by a CITROËN dealer or a qualified workshop.
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 system, a drop in the brake fluid level indicates that the brake pads are worn.

Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does not block traffic: the ground must be level, stable and non-slippery ground. Apply the parking brake unless it has been programmed to automatic mode, switch off the ignition and engage first gear * to lock the wheels. Check that the braking warning lamps in the instrument panel are on (not flashing). If necessary, place a chock under the wheel diagonally opposite the wheel to be changed. The occupants must get out of the vehicle and wait where they are safe. Never go underneath a vehicle raised using a jack; use an axle stand.
