Stop & Start
Operation
- with a manual gearbox, at speeds below
12 mph (20 km/h) with BlueHDi Diesel
versions, when you put the gear lever into
neutral and release the clutch pedal,
- with an automatic gearbox, vehicle
stationary, when you press the brake pedal
or place the gear lever in position N .
Going into engine STOP
mode
The "ECO" warning lamp comes on
in the instrument panel and the engine
goes into standby automatically: 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.
Special cases: STOP mode
unavailable
In this case, the "ECO"
warning
lamp flashes for a few seconds, then
goes off.
This operation is perfectly normal. STOP mode is not invoked when:
- the vehicle is on a steep slope
(up or down),
- 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
comfortable temperature in the passenger
compartment,
- 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.
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...).
The engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
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 ground has been crossed on the right,
- on the left-hand side, if the marking on the
ground has been crossed on the left.
No warning is transmitted while the direction
indicator is active and for approximately
20 seconds after the direction indicator is

System which detects the involuntary crossing
of longitudinal traffic lane markings on the
ground (solid or broken line).
Sensors, fitted below the front bumper, trigger
a warning if the vehicle drifts over a lane
marking (speed higher than 50 mph (80 km/h)).
The detection may be impeded:
- if the sensors are dirty (mud, snow...),
- if the markings on the ground are
worn,
- if there is little contrast between the
markings on the ground and the road
sur face.
The lane departure warning system
cannot in any circumstances replace
the need for vigilance on the part of the
driver.
It is necessary to observe driving
regulations and take a break every
two hours.

"Hydractive III +" electronic suspension
The suspension automatically and instantly
adjusts to different driving styles and to
the profile of the road, providing the best
compromise between occupant comfort and
vehicle road holding.

suspension settings, maximising comfort at the
same time as constantly ensuring the highest
level of safety. It also automatically corrects
ride height, according to the vehicle load and
driving conditions.
