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.

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.
