Your vehicle may be equipped with a "Stop & Start" system, in association with an Electronic Gearbox System; this s h u t s d o w n t h e e n g i n e d u r i n g s t o p p i n g p h a s e s ( r e d l i g h t s , t r a f fi c j a m s , t e m p o r a r y h a l t s , e t c . ) .
During these phases, your vehicle uses no fuel, emits no pollut ants and is completely silent.
The engine restarts instantly when you want to move forward ag ain.
Functioning of the "Stop & Start" system:
If you brake to stop your vehicle, the engine shuts down just before the vehicle comes to a complete halt; the green "ECO" warning lamp lights up in the instrument panel. The en gine remains shut down for as long as you keep your foot, even lightly, on the brake pedal.
As you release the brake pedal, the engine restarts automaticall y and instantly. The green "ECO" warning lamp goes out. You can then accelerate to move forward again.

Situations where the engine does not shut down:
Before shutting down the engine, the system automatically and instantly checks that a certain number of conditions touching on safety, cabin comfort or engine protection are met .
For example, the engine will not shut down, or it will restart by itself: W i t h i n t h e f e w m i n u t e s f o l l o w i n g fi r s t s t a r t i n g ( e n g i n e c o l d ) .

The parking brake is actioned by pulling on the lever with a force appropriate to any slope.
To facilitate the action on the lever, you are recommended t o press the brake pedal at the same time.

ABS system
The ABS system enhances your safety by preventing the wheels from locking in the event of sudden braking or in conditions of poor road adherence. It enables you to retain control of the steering.
The functioning capability of all the electrical components essential to the ABS is monitored electronically before and during your journey. The ABS warning lamp lights up when you switch on the ignition: it should go out after a few seconds.
If the monitoring warning lamp does not go out, that means that the ABS has disconnected because there is a fault. Also, the fact that the monitoring warning lamp comes on durin g the journey shows that the ABS system is inactive.

On roads with poor adherence (chippings, snow, ice etc.), it is always imperative to drive with prudence.
System of emergency braking assistance
(For vehicles with the ABS system)
The emergency braking assistance system helps you to attain the requ ired braking pressure more rapidly, thus to reduce the stopping distance. It operates as a function of the speed of action on the brake pedal, decreasing the resistance to this action. To prolong this action of the emerg ency braking assistance system, simply keep your foot on the brake pedal.
Emergency braking or sudden deceleration automatically operates th e hazard warning lamps. They will cease to operate automatically, or manually if you press the hazard lamps button on the dashboard.

This system is associated with the ABS and in addition to the ABS. In the event of a loss of control of the vehicle by the driver, the ESP system acts automatically on one or more wheels and also on the engine to bring the vehicle back on trajectory.
Operation

Deactivation
In exceptional conditions (vehicle stuck in snow, soft ground, e tc.) it may prove useful to deactivate the ESP systems to allow the wheels to spin and thus regain traction.Press button A.
The warning lamp associated with control A (ESP Off) lights up, as does the ESP warning lamp on the instrument panel.
The ESP system is no longer active.
The ESP system reactivates:Automatically after the ignition has been switched off.Automatically when you drive at above approx. 50 k m / h ( a p p r o x . 3 0 m p h ) ( A c c o r d i n g t o v e r s i o n ) .
