Driver’s responsibility
when parking or stopping
the vehicle
Never leave an animal,
child or adult who is not self-suffi-
cient alone in your vehicle, even for
a short time.
They may pose a risk to themselves
or to others by starting the engine,
activating equipment such as the
electric windows or locking the
doors, for example.
Also, in hot and/or sunny weather,
please remember that the tempera-
ture inside the passenger compart-
ment increases very quickly.
RISK OF DEATH OR SERIOUS
INJURY.
Never switch off the igni-
tion before the vehicle has
stopped completely. Once
the engine has stopped, the
brake servo, power-assisted steer-
ing, etc. and the passive safety de-
vices such as air bags and preten-
sioners will no longer operate.

2.13
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;
– ...
For vehicles fitted with a manual gear-
box, the restarting of the engine may be
stopped if the clutch pedal is released
too quickly and a gear is engaged.

message “Stop & Start deactivated” will
appear on the instrument panel and the
integrated warning light 2 on the switch
will light up.
Pressing again will reactivate the
system. The message “Stop & Start ac-
tivated” will appear on the instrument
panel and the integrated warning light 2
on switch 1 will go out.
Note: With the engine on standby,
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.

2.15
SPECIAL FEATURES OF DIESEL VERSIONS
Diesel engine speed
Diesel engines are fitted with an injec-
tion pump which prevents the engine
speed being exceeded irrespective of
the gear selected.
If the message “Check antipollution
system” is displayed along with warn-
ing lights
Ä and ©, consult an
authorised dealer immediately.
When driving, depending on the fuel
grade used, it is possible that white
smoke may be emitted.
This is due to the exhaust particle filter
being cleaned automatically, and does
not affect the way the vehicle runs.
Running out of fuel
If the tank has been completely
drained, the system must be reprimed
after the tank is refilled: See “Fuel
tank” in section 1 before restarting the
engine.
Do not park the vehicle or
run the engine in locations
where combustible sub-
stances or materials such
as grass or leaves can come into
contact with the hot exhaust system.
Precautions to be taken in
winter
To avoid any faults in icy weather:
– ensure that the battery is always fully charged,
– always keep the diesel tank rela- tively full to avoid water vapour con-
densing in it and accumulating at the
bottom of the tank.

2.17
ELECTRONIC PARKING BRAKE (1/3)
Note:
To indicate that the electronic parking
brake is released, a beep sounds and
the message “Apply parking brake” ap-
pears on the instrument panel:
– with the engine running: when the driver’s door is opened;
– with the engine switched off (eg. when the engine stalls): when a front
door is opened.
In this case, pull and release switch 2 to
apply the assisted parking brake.
Assisted release of the parking
brake
The brake will be released as soon as
the vehicle starts and accelerates.
Assisted operation
The electronic parking brake immobi-
lises the vehicle when the engine is
switched off by pressing the engine
start/stop button 1 or by turning the
ignition key (key in the “ ON" 2 po-
sition).
In all other circumstances, for example
stalling of the engine or placing of
the engine on standby by the Stop
and Start function (refer to the informa-
tion on the "Stop and Start" function in
Section 2), the electronic parking brake
is not applied automatically. Manual
mode must be used. For certain country-specific model ver-
sions, the assisted brake application
function is not activated. Refer to the
information on “Manual operation”.
To confirm that the electronic parking
brake is applied, the message “Parking
brake on” and warning light
}
on the instrument panel and warning
light 3 on the switch 2 light up.
After the engine is switched off, indi-
cator light 3 goes out several minutes
after the electronic parking brake has
been applied and indicator light
}
goes out when the vehicle is locked.
Before leaving the vehi-
cle, check that the assisted
parking brake is fully ap-
plied. Warning light 3 on
switch 2 and warning light
}
on the instrument panel light up to
show that the parking brake is ap-
plied but go out when the doors are
locked.

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.

Driving advice and ECO
driving
Behaviour
– Drive carefully for the first few miles until the engine reaches its normal
operating temperature, rather than
let it warm up while the vehicle is sta-
tionary.
– Speed is expensive.
– Dynamic driving with a lot of frequent acceleration and braking is expen-
sive on fuel in comparison to the time
saved.
– Do not overrev the engine in the in-termediate gears.
You should always use the highest gear possible.
– Avoid sudden acceleration.
– Brake as little as possible. If you an- ticipate an obstacle or bend in ad-
vance, you may then simply release
the accelerator pedal.
– Do not try to maintain the same speed up a hill, accelerate no more
than you would on flat ground. Keep
your foot in the same position on the
accelerator pedal.
– Double declutching and accelerating before switching off are unnecessary
in modern vehicles.
Obstructions to the driver
On the driver’s side, only
use mats suitable for the
vehicle, attached with the
pre-fitted components, and check
the fitting regularly. Do not lay one
mat on top of another.
There is a risk of wedging the
pedals
DRIVING ADVICE, ECO-DRIVING (4/5)
– Bad weather, flooded roads:
Do not drive through
floods if the water is
above the lower edge of
the wheel rims.

2.25
MAINTENANCE AND ANTIPOLLUTION ADVICE
Your vehicle complies with criteria for
recycling and recovering vehicles at the
end of their service life, which entered
into force in 2015.
Some parts of your vehicle have there-
fore been designed to facilitate future
recycling.
These parts are easy to remove so
that they can be recovered and reproc-
essed by recycling companies.
By virtue of its design, moderate fuel
consumption and initial settings, your
vehicle also conforms to current anti-
pollution regulations. The manufac-
turer is actively striving to reduce pol-
lutant exhaust gas emissions and to
save energy. But the fuel consumption
of your vehicle and the level of pollutant
exhaust gas emissions are also your
responsibility. Ensure that it is main-
tained and used correctly.
Maintenance
It is important to remember that fail-
ure to respect antipollution regulations
could lead to legal action being taken
against the vehicle owner.In addition, replacing engine, fuel
supply system and exhaust compo-
nents with parts other than those origi-
nally recommended by the manufac-
turer may alter your vehicle so that it
no longer complies with anti-pollution
regulations.
Have your vehicle adjusted and
checked by an authorised dealer, in ac-
cordance with the instructions given in
your maintenance schedule: they will
have all the equipment necessary for
ensuring that your vehicle is maintained
to its original standard.
Engine adjustments
– Spark plugs:
for optimum condi-
tions of use, output and performance
the specifications laid down by our
Design Department must be strictly
applied.
If the spark plugs have to be changed, use the make, type and gap specified
for your vehicle’s engine. Contact an
authorised dealer for this.
– Air filter, fuel filter: a choked ele-
ment will reduce efficiency. It must
be replaced.
– Ignition and idle speed: no adjust-
ment is needed.
Exhaust gas monitoring
system
The exhaust gas monitoring system will
detect any operating faults in the vehi-
cle’s antipollution system.
If this system malfunctions, toxic sub-
stances may be released into the at-
mosphere or damage may occur.
ÄThis warning light on the in-
strument panel will indicate if
there are any faults in the system:
This lights up when the ignition is
switched on and goes out when the
engine is started.
– If it lights up continuously, consult an approved Dealer as soon as possi-
ble;
– if it flashes, reduce the engine speed until the light stops flashing. Contact
an authorised dealer as soon as pos-
sible.

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.

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.
DRIVER CORRECTION DEVICES AND AIDS (3/10)

2.46
Operating faults
If the system detects a fault, the mes-
sage “Check blind spot alert” is dis-
played on the instrument panel. Consult
an approved dealer.
Note: when the engine is started, the
indicator light 6, display B , flashes
three times. It is normal.
– The system’s detection
range operates according
to a standard lane width. If
you are driving in wide traf-
fic lanes, the system might not
be able to detect a vehicle in the
blind spot.
– The system might be disrupted momentarily if it is exposed to
strong electromagnetic waves
(as beneath high-tension power
lines) or to very poor weather
conditions (heavy rain, snow,
etc.). Remain aware of driving
conditions.
There is a risk of accidents.
BLIND SPOT WARNING (4/4)
Because sensors have
been installed in the bump-
ers, any work (repairs, re-
placements, touching up of
paintwork) must be carried out by a
qualified professional.
