CHILD SAFETY: choosing a child seat mounting (1/4)
There are two ways of attaching child
seats: via the seat belt or using the
ISOFIX system.
The seat belt must never
be twisted or the tension
relieved. Never pass the
shoulder strap under the
arm or behind the back.
Check that the seat belt has not
been damaged by sharp edges.
If the seat belt does not operate nor-
mally, it will not protect the child.
Consult an approved dealer. Do not
use this seat until the seat belt has
been repaired.
Do not use the child seat
if it may unfasten the seat
belt restraining it: the base
of the seat must not rest on
the buckle and/or catch of the seat
belt.
Attachment via the seat belt
The seat belt must be adjusted to
ensure that it is effective in the event of
harsh braking or an impact.
Ensure that the strap paths indicated
by the child seat manufacturer are re-
spected.
Always check that the seat belt is cor-
rectly fastened by pulling it up, then
pulling it out fully whilst pressing on the
child seat.
Check that the seat is correctly held by
moving it from side to side and back
to front: the seat should remain firmly
fixed.
Check that the child seat has not been
installed at an angle and that it is not
resting against a window.

FUNCTION STOP AND START (4/4)
Special feature of the automatic
engine re-start
Under certain conditions, the engine
can restart on its own in order to guar-
antee your safety and comfort.
This can occur especially when:
– the outdoor temperature is too low or too high (less than around 5°C or
higher than around 35°C);
– the “Clear View” function is activated (please see “Automatic climate con-
trol” in Section 3);
– the battery is not sufficiently charged;
– the vehicle speed is above 3 mph (5 km/h) (downhill slope, etc.);
– repeated pressing on the brake pedal or braking system require-
ment;
– ...

press switch 1 to automatically re-
start the engine.
The system is automatically reacti-
vated each time the vehicle is started
(see “Starting, stopping the engine” in
Section 2).
Operating faults
When the message “Check Stop &
Start” appears on the instrument panel
and the integrated warning light 2 lights
up on the switch 1, the system is deac-
tivated.
Please consult an authorised dealer.
The ignition must be
switched off before leav-
ing the vehicle (please see
the information on “Starting,
stopping the engine” in Section 2).
Special feature of vehicles with
a key: for some of these condi-
tions the automatic restarting of the
engine is inhibited if a front door is
open.

2.19
Operating faults
– If there is a fault, the © warning
light illuminates on the instrument
panel accompanied by the “Check
parking brake” message and, in
some cases, the
} warning
light.
Please contact an authorised dealer
as soon as possible.
– If there is an assisted parking brake fault, the warning light
® comes
on, along with the message “Braking
system fault”, a beep and, in some
cases, the warning light
}.
This means that you must stop as
soon as traffic conditions allow.
Versions with an automatic
gearbox
For safety reasons, automatic release
is deactivated when the driver’s door
is open or not shut properly and the
engine is running (in order to prevent
the vehicle from moving without the
driver). The “Release parking brake
manually” message appears on the
instrument panel when the driver de-
presses the accelerator.
ELECTRONIC PARKING BRAKE (3/3)
It is therefore essential to
immobilise the vehicle by
engaging first gear (manual
gearbox) or position P (au-
tomatic gearbox). If the slope re-
quires it, chock the vehicle.
Never leave your vehicle
without moving the selec-
tor lever to position P and
switching off the engine.
This is because when the vehicle is
stationary with the engine running
and a gear engaged, the vehicle
may begin to move.
There is a risk of accidents.If no lights or sounds are ap-
parent, this indicates a fault
in the instrument panel. This
indicates that it is essential
to stop immediately (as soon as traf-
fic conditions allow). Ensure that the
vehicle is correctly immobilised and
contact an approved Dealer.
If the message “Electric fail-
ure DANGER” or “Check
battery” appears, manually
activate the electronic park-
ing brake by pulling switch 2 (or po-
sition the gear lever in P for auto-
matic gearboxes) before stopping
the engine.
Risk of loss of immobilisation of the
vehicle.
Contact an authorised dealer.

2.22
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 vehicles
fitted with an automatic gearbox, in the
deceleration phases (with the foot fully
off the accelerator pedal), switching to
freewheeling (automatic neutral) de-
creases engine braking and allows you
to farther without accelerating in order
to save fuel.Activating the function
The function can be activated:
– by pressing switch
5;
– by pressing the switch 6 (please refer
to the information on “Multi-Sense” in
Section 3);
– from the navigation menu on the multimedia screen (please refer to
the instructions for the multimedia
equipment).
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 5.
The warning light
 goes out on
the instrument panel to confirm deac-
tivation.
To activate/deactivate the “free wheel”
mode, see “Vehicle settings customisa-
tion menu” in Section 1.

DRIVER CORRECTION DEVICES AND AIDS (1/10)ABS (anti-lock braking
system)
Under heavy braking, the ABS prevents
the wheels from locking, allowing the
stopping distance to be managed and
keeping control of the vehicle.
Under these circumstances, the vehi-
cle can be steered to avoid an obstacle
whilst braking. In addition, this system
can increase stopping distances, par-
ticularly on roads with low surface grip
(wet ground etc.).
You will feel a pulsation through the
brake pedal each time the system is
activated. The ABS does not in any way
improve the vehicle's physical perform-
ance relating to the road surface and
roadholding. It is still essential to follow
the rules of good driving practice (such
as driving at a safe distance from the
vehicle in front etc.).
– ABS (anti-lock braking system);
– ESC
(electronic stability control)
with understeer control and trac-
tion control;
– emergency brake assist;
– active emergency braking;
– hill start assistance;
– rear wheel steering.
Other driving assistance systems are
detailed on the following pages.
In an emergency, apply firm and
continuous pressure to the brake
pedal. There is no need to pump
it repeatedly. The ABS will modu-
late the force applied in the braking
system.
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle behav-
iour to be adapted to suit the driving
conditions.
The functions do not take the place
of the driver. They do not increase
the vehicle’s limits and should
not encourage you to drive more
quickly. Therefore, they can under
no circumstances replace the vigi-
lance or responsibility of the driver
when manoeuvring the vehicle (the
driver must always be ready for
sudden incidents which may occur
when driving).

2.31
DRIVER CORRECTION DEVICES AND AIDS (2/10)
Operating faults:
–
© and x lit up on the in-
strument panel accompanied by the
messages “Check ABS”, “Check
braking system” and “Check ESC”:
this indicates that the ABS, the ESC
and the emergency brake assist are
disabled. Braking is always ena-
bled;
–
x, D, © and ®
lit on the instrument panel accom-
panied by the message “Braking
system fault”: this indicates a fault
with 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
Dealer.

2.32
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.
