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.

2.16
Gear lever
Selecting reverse gear
Vehicle with manual gearbox: Follow
the grid marked on knob 1 and, depend-
ing on the vehicle, lift the ring against
the knob to engage reverse gear.
Vehicles with automatic gear-
box: refer to the information on the
“Automatic gearbox” in Section 2.
The reversing lights will come on as
soon as reverse gear is selected with
the ignition on.

GEAR LEVER/HANDBRAKE
Handbrake
To release:
Pull the lever 3 up slightly, press
button 2 and then lower the lever to the
floor.
The red warning light
} on the in-
strument panel will remain on, accom-
panied by the message “Parking brake
on” and a beep if you are driving with an
incorrectly released handbrake.

When stationary, and de-
pending on the slope and/or
vehicle load, it may be nec-
essary to pull up the hand-
brake at least two extra notches and
engage a gear (1
st or reverse gear)
for vehicles with a manual gearbox
or position P for vehicles with an au-
tomatic gearbox.
An impact to the under-
side of the vehicle while
manoeuvring (e.g.: strik-
ing a post, raised kerb or
other street furniture) may result in
damage to the vehicle (e.g.: defor-
mation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap-
proved Dealer.
Make sure that the hand-
brake is properly released
when driving (red indicator
light off), otherwise over-
heating, or even damage, may
occur.
To apply:
Pull lever 3 upwards. Check that the
vehicle is immobilised. The warning
light
} on the instrument panel will
come on.

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.

2.24
DRIVING ADVICE, ECO-DRIVING (5/5)
Advice on use
– Opt for ECO mode.
– Electricity is fuel; switch off all the electrical components which are
not really needed. However (safety
first), keep your lights on when the
visibility is bad (“see and be seen”).
– Use the air vents. Driving with the windows open at 60 mph (100 km/h)
will increase fuel consumption by
4%.
– Never fill the fuel tank right to the brim to avoid overflow.
– In vehicles fitted with air condi-
tioning, it is normal to observe an
increase in fuel consumption (espe-
cially in urban conditions) when it is
used. For vehicles fitted with manual
air conditioning, switch off the system
when it is not required.
Recommendations for reducing
consumption and therefore help-
ing to preserve the environment:
If the vehicle has been parked in the
sun, open the doors for a few mo-
ments to let the hot air escape before
starting the engine.
– Do not leave an empty roof rack fitted to the vehicle.
– It is better to fit a trailer for bulky ob- jects.
– When towing a caravan, fit a wind deflector and adjust it carefully.
– Avoid using the car for door-to-door calls (short journeys with long waits
in between) because the engine
never reaches its normal operating
temperature.
Tyres
– An underinflated tyre increases fuel consumption.
– Opt for the highest speed pressure or the pressure recommended to op-
timise fuel consumption indicated
on edge of the driver’s door (please
refer to the information on “Tyre infla-
tion pressure” in Section 4).
– The use of non-recommended tyres can increase fuel consumption.

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.

2.33
DRIVER CORRECTION DEVICES AND AIDS (4/10)
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.

2.36
DRIVER CORRECTION DEVICES AND AIDS (7/10)
Active emergency braking
This function is an additional driving aid. This function is not under any
circumstances intended to replace the due care and attention of the
driver, who should at all times be in control of the vehicle.
System servicing/repairs
– In the event of an impact, the sensor alignment may become changed, and \
its operation will consequently be affected. Deactivate the function, then consult
an authorised dealer.
– Any work in the area where the radar is located (repairs, replacements,\
touch- ing up of paintwork) must be carried out by a qualified professional.
Only an authorised dealer is qualified to service the system.
In the event of system disturbance
Some conditions can disturb or damage the operation of the system, such \
as:
– a complex environment (metal bridge, etc.);
– poor weather conditions (snow, hail, black ice, etc.).
Risk of inadvertent braking.
Operating faults
When the system detects an operating
fault, the
\b warning light lights up
on the instrument panel, with the mes-
sage “Active braking disconnected”.
There are two possibilities:
– The system is temporarily experienc- ing difficulties (for example: sensor
obscured by dirt, mud, snow etc.);
in this case, park the vehicle and
switch off the engine. Clean the de-
tection zone of the radar. When you
next start the engine, the warning
light and the message go out;
– If this is not the case, this may arise from another cause; contact an
Approved Dealer.

2.37
DRIVER CORRECTION DEVICES AND AIDS (8/10)
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.

2.40
LANE DEPARTURE WARNING (1/3)
This system notifies the driver when
they accidentally cross a continuous or
broken line.
This function uses a camera attached
to the windscreen, behind the rear-view
mirror.
This function is an additional driving aid. This function is not under any
circumstances intended to replace the due care and attention of the
driver, who should at all times be in control of the vehicle.
System servicing/repairs
– In the event of an impact, the camera alignment may be changed, and its \
op- eration may consequently be affected. Deactivate the function, then consult an
authorised dealer.
– Any work in the area where the camera is located (repairs, replacements\
, wind- screen modifications etc.) must be carried out by a qualified professio\
nal.
Only an authorised dealer is qualified to service the system.
In the event of system disturbance
Some conditions can disturb or damage the operation of the system, such \
as:
– a complex environment (tunnel etc.);
– poor weather conditions (snow, hail, black ice etc.);
– poor visibility (night, fog etc.);
– road markings which are worn, lacking in contrast or very widely spaced \
from one another (lines partially erased etc);
– being dazzled (glaring sun, lights of vehicles travelling in the opposi\
te direction etc.);
– the road is narrow, winding or undulating (tight bends etc.);
– closely following a vehicle travelling in the same lane.
Risk of false alarms or absence of warnings
