DRIVING ADVICE, ECO-DRIVING (3/5)
ECO mode
ECO mode is a function which opti-
mises fuel consumption. It acts upon
certain power consuming systems in
the vehicle (heating, air conditioning,
power-assisted steering, etc.) and on
certain driving actions (acceleration,
gear changing, cruise control, decele-
ration, etc.).
Limiting acceleration enables low fuel
consumption in urban and surrounding
areas. Reduced usage of the air condi-
tioning reduces fuel consumption with-
out affecting heating comfort.
Free wheel in ECO mode
Depending on the vehicle, for vehi-
cles fitted with an automatic gearbox,
switching to “free wheel” is favoured to
slow down the vehicle without using the
engine brake. By releasing the acceler-
ator pedal completely to anticipate de-
celeration, you will save fuel.Activating the function
The function can be activated:
– by pressing switch
6.
– by pressing the switch 7 (please refer
to the information on “Multi-Sense” in
Section 3);
– from the navigation menu on the multimedia screen (please refer to
the multimedia instructions).
The warning light
 comes on on
the instrument panel to confirm activa-
tion.
While driving, it is possible to leave the
ECO mode temporarily in order to im-
prove engine performance.
For this, depress the accelerator pedal
firmly and fully.
ECO mode is reactivated when you
take pressure off the accelerator pedal.
Disabling the function
Press switch 6.
The warning light
 goes out on
the instrument panel to confirm deac-
tivation.
The distance covered in “free wheel”
mode is displayed, depending on the
vehicle, on the multifunction screen 4
or the instrument panel 5.
To activate/deactivate the “free wheel”
mode, see “Vehicle settings customisa-
tion menu” in Section 1.

up on the instrument panel alongside
the message “Braking system fault”:
this indicates a fault in the braking
system.
In both cases, consult an approved
dealer.
Your braking systems
are partially operational.
However, it is dangerous
to brake suddenly and
it is essential to stop immediately,
as soon as traffic conditions allow.
Contact an approved dealer.Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions
allow. Switch off the engine and do
not restart it. Contact an approved

Electronic stability control
ESC with understeer control
and traction control
Electronic stability control ESC
This system helps you to keep control
of the vehicle in critical driving condi-
tions (avoiding an obstacle, loss of grip
on a bend, etc.).
Operating principle
A sensor in the steering wheel detects
the direction selected by the driver.
Other sensors throughout the vehicle
measure the actual direction.
The system compares driver input to
the actual trajectory of the vehicle and
corrects the trajectory if necessary by
controlling the braking of certain wheels
and/or engine power. In the event that
the system is engaged, indicator light
 flashes on the instrument panel.Understeer control
This system optimises the action of the
ESC in the case of pronounced under-
steer (loss of front axle road holding).
Traction control
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
Operating principle
Using the wheel sensors, the system
measures and compares the speed of
the drive wheels at all times and slows
down their over-rotation. If a wheel is
starting to slip, the system brakes au-
tomatically until the drive supplied be-
comes compatible with the level of grip
under the wheel again.
The system also adjusts the engine
speed to the grip available under the
wheels, independently of the pressure
exerted on the accelerator pedal.
Operating faults
When the system detects an operat-
ing fault the message “Check ESC” and
warning light
© and  appear
on the instrument panel.
In this case, the ESC and traction con-
trol system are deactivated. Consult an
authorised dealer.

Emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
Operating principle
The system is for detecting an emer-
gency braking situation. In this case,
the braking assistance immediately de-
velops maximum power and may trig-
ger ABS regulation.
ABS braking is maintained as long as
the brake pedal is applied.
Hazard warning lights switching on
Depending on the vehicle, these may
light up in the event of sudden decel-
eration. Braking anticipation
Depending on the vehicle, when you
rapidly release the accelerator, the
system anticipates the braking ma-
noeuvre in order to reduce stopping
distances.
Special cases
When using the cruise control:
– if you use the accelerator, when you
release it, the system may be trig-
gered;
– if you do not use the accelerator, the system will not be triggered.
Operating faults
When the system detects an operat-
ing fault the message “Check brak-
ing system” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.

DRIVER CORRECTION DEVICES AND AIDS (5/10)
If the driver depresses the brake pedal
and the system still detects a risk of col-
lision, the brake force is increased.
If the driver fails to react following
an alert of an imminent collision, the
system activates the brakes.
Active emergency braking
Using the sensor 1, the system calcu-
lates the distance separating the vehi-
cle from the one in front and alerts the
driver if there is a risk of a front-end col-
lision. The driver can then brake the ve-
hicle to limit the damage arising from a
collision.
Note: Make sure that the sensor 1 is
not obscured (by dirt, mud, snow, etc.).
Operation
When driving (speed between 18.6 and
93 mph (30 and 150 km/h), if there is a
risk of collision with the vehicle in front,
depending on the vehicle:
– the warning light
 is displayed
in red on the instrument panel, ac-
companied by a beep;
or
– the indicator 2 is displayed in red on
the instrument panel and, depending
on the vehicle, on the head up dis- play, accompanied by a beep.
The system only detects vehicles
driving in the same direction of traf-
fic. The system cannot detect mo-
torcycles because of the difficulty in
forecasting their trajectory.

Active emergency braking
Limitation of the system operation
– The system will only respond to vehicles which are moving or which have \
been sensed as moving.
– A vehicle travelling in the opposite direction will not trigger any alert\
or any action on the system operation.
– The sensor area should be kept clean and free of any modifications in or\
der to ensure the proper operation of the system.
– The system cannot respond to small vehicles such as motorbikes or bicycl\
es as effectively as to other vehicles.
Deactivating the function
You must disable the function if:
– the brake lights are not functioning;
– the front of the vehicle has undergone an impact or been damaged;
– the vehicle is being towed (breakdowns).
Halting the function
You can halt the active braking function at any time by tapping the accel\
erator pedal or by turning the steering wheel in a avo id-
ance manoeuvre.
If the driver notices any unusual behaviour in the system, please consul\
t an authorised dealer.

CRUISE CONTROL (4/4)Switching off the function
The cruise control function is deacti-
vated if you press switch 1: in this case
a speed is no longer stored. The switch-
ing off, depending on the vehicle, of the
green indicator light
 or of the green
indicator lights
 and , and of the
associated message on the instrument
panel confirm that it is off.
Returning to the cruising speed
If a speed is stored, it can be recalled,
once you are sure that the road con-
ditions are suitable (traffic, road sur-
face, weather conditions, etc.). Press
switch
3 (R) if the vehicle speed is
above 20 mph (30 km/h).
When the stored speed is recalled,
activation of the cruise control is con-
firmed by displaying of the cruising
speed along with the message “Cruise
control” and, depending on the vehicle,
lighting of the indicator light
.
NB: if the speed previously stored is
much higher than the current speed,
the vehicle will accelerate more rapidly
to reach this threshold.
When the cruise control function is
put on standby, pressing switch 2
side a (+) reactivates the cruise
control function without taking into
account the stored speed: it is the
speed at which the vehicle is moving
that is taken into account.
Putting the function on
standby
The function is set to standby if you:
– use the switch 5 (O);
– the brake pedal;
– depress the clutch pedal or the shift into neutral if the vehicle has an au-
tomatic gearbox.
The cruising speed is stored and dis-
played on the instrument panel accom-
panied by the message “Memorised”.
Standby is confirmed by displaying of
cruising speed in grey and the mes-
sage “Memorised” and depending on
the vehicle the indicator light
 going
out.
Putting the cruise control
on standby or switching it
off does not cause a rapid
reduction in speed: you
must brake by depressing the brake
pedal.
