DRIVING ADVICE, ECO-DRIVING (5/5)
Advice on use
– Favour the 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.

MAINTENANCE AND ANTIPOLLUTION ADVICE
Your vehicle complies with criteria for
recycling and recovering vehicles at the
end of their service life which will come
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 anti-pollution 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.

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 re-
start 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.
DRIVER CORRECTION DEVICES AND AIDS (3/10)

2.36
DRIVER CORRECTION DEVICES AND AIDS (7/10)
Active emergency braking
This function is an additional driving aid. However, 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
 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.

Operating faults
If the system detects a fault, the mes-
sage “Check blind spot alert” is dis-
played on the instrument panel. Consult
an authorised 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.

Using the sensor 1 , this function noti-
fies the driver about the time interval
separating them from the vehicle in
front, so they can respect a safe dis-
tance between the two vehicles.
Note: make sure that the sensor 1 is
not obscured (by dirt, mud, snow, etc.).
The function is activated when the ve-
hicle speed is between about 20 and
125 mph (30 and 200 km/h).
When the engine is started, the func-
tion maintains the same status that was
active when the engine was last stop-
ped.
You can access menu “Driving as-
sistance” directly from button 3
\b.
This function is an additio-
nal driving aid. However,
this function is not under
any circumstances in-
tended to replace the due care and
attention of the driver, who should at
all times be in control of the vehicle.

ADAPTIVE CRUISE CONTROL (4/7)
Exceeding the cruising speed
The cruising speed may be exceeded
at any time by depressing the accelera-
tor pedal.
When exceeding this speed, the cruis-
ing speed and the following bars show
red and the cruising speed flashes on
the instrument panel: the distance con-
trol function is no longer activated.
Then, release the accelerator: cruise
and distance control will automatically
reactivate unless the function has been
set to standby.
Putting the function on
standby
The function is set to standby if:
– you press switch 4 (O);
– you depress the brake pedal;
– you depress the clutch pedal;
– you use the gear lever;
– the vehicle speed is lower than 25 mph (40 km/h) or over 100 mph
(160 km/h);
– the engine speed is too low or too high;
– certain driver correction devices and aids are triggered (ABS, ESC, etc.)
In the latter three cases, the message
“Adaptive cruise Adaptive cruise” is dis-
played on the instrument panel when
the function is set to standby.
Standby is confirmed by the display of
the cruising speed in grey and the mes-
sage “Adaptive cruise ctrl”. 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 around 30 mph (50 km/h).
When the stored speed is recalled,
activation of the cruise control is con-
firmed by the illumination of the cruis-
ing speed in green, along with the mes-
sage “Adaptive cruise ctrl”.
When the cruise control function is put
on standby, pressing switch 2 side a
(+) reactivates the cruise control func-
tion without taking into account the
stored speed: it is the speed at which
the vehicle is moving that is taken into
account.
