METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS (2/3)
Driver and passenger front
airbags
It is fitted to the front seats on the driv-
er’s side and, depending on the vehicle,
on the passenger’s side as well.
Depending on the vehicle, an “air bag”
marking on the steering wheel and the
dashboard (air bag area A) indicates
that this device is fitted.
Each air bag system consists of:
– an air bag and gas generator fitted on the steering wheel for the driver
and in the dashboard for the front
passenger;
– an electronic unit for system monitor- ing which controls the gas generator
electrical trigger system;
– a special
å tell-tale light;
– remote sensors. Operation
This system is only operational when
the ignition is switched on.
If a severe frontal impact occurs, the
air bag(s) inflate rapidly, thus cushion-
ing the impact of the driver’s head and
chest on the steering wheel and those
of the passenger on the dashboard;
the air bag(s) then deflate immediately
after the impact to prevent the occu-
pants from being impeded in any way
when leaving the vehicle.
A
The air bag system uses
pyrotechnic principles. This
explains why, when the air
bag inflates, it will gener-
ate heat, produce smoke (this does
not mean that a fire is about to start)
and make a noise upon detonation.
In a situation where an air bag is
required, it will inflate immediately
and this may cause some minor, su-
perficial grazing to the skin or other
problems.

B automatic wiper function.
When this position is selected, the system detects water on the wind-
screen and triggers the wipers at a
suitable wiping speed. It is possi-
ble to change the triggering thresh-
old and the time sweeps by turning
ring 2:
– E: minimum sensitivity
– F: maximum sensitivity
Note: in foggy weather or during
snowfalls, wiping is not automatically
triggered and remains under the
driver’s control.

Special note
When driving the vehicle, the wiping
speed slows down whenever the ve-
hicle stops. For example, fast wiping
speed will slow to normal wiping speed.
As soon as the vehicle moves off,
wiping will return to the speed originally
selected.
If stalk 1 is operated, it overrides and
cancels the automatic function.
Note: in the event of mechanical sei-
zure, the system automatically cuts the
power supply to the wipers.

ENVIRONMENT
Emissions
Your vehicle has been designed to
emit fewer greenhouse gases (CO2)
while in use, and therefore to consume
less fuel (eg. 140 g/km, equivalent to
5.3 l/100 km for a diesel vehicle).
Our vehicles are also equipped with a
particle filter system including a cata-
lytic converter, an oxygen sensor and
an active carbon filter (the latter pre-
vents vapour from the fuel tank being
released into the open air).
For certain diesel vehicles, this system
also has a particle filter to reduce the
volume of soot particles emitted.
Please make your own
contribution towards
protecting the environment
too
– Worn parts replaced in the course of routine vehicle maintenance (vehi-
cle battery, oil filter, air filter, batter-
ies, etc.) and oil containers (empty or
filled with used oil) must be disposed
of through specialist organisations. – At the end of the vehicle’s service
life, it should be sent to approved
centres to ensure that it is recycled.
– In all cases, comply with local legis- lation.
Recycling
Your vehicle is 85% recyclable and
95% recoverable.
To achieve these objectives, many of
the vehicle components have been de-
signed to enable them to be recycled.
The materials and structures have
been carefully designed to allow these
components to be easily removed and
reprocessed by specialist companies.
In order to preserve raw material re-
sources, this vehicle incorporates nu-
merous parts made from recycled plas-
tics or renewable materials (vegetable
or animal-derived materials such as
cotton or wool).
Your vehicle has been designed with
respect for the environment in mind for
its entire service life: during production,
use and at the end of its life.
This commitment is illustrated by the of
the manufacturer eco² signature.Manufacture
Your vehicle has been manufactured at
a factory which complies with a policy
to reduce the environmental impact
on the surrounding areas (reduction of
water and energy consumption, visual
and noise pollution, atmospheric emis-
sions and waste water; sorting and re-
using waste).

Operating faults
When the system detects an operating
fault the message “CHECK ESC” and
warning light
© and  appear
on the instrument panel. In this case,
the ESC and traction control system
are deactivated.
Consult an approved dealer.
Electronic stability program
(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.
DRIVING CORRECTION DEVICES AND AIDS (2/8)
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.
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).

2.18
DRIVING CORRECTION DEVICES AND AIDS (3/8)
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.
Operating faults
When the system detects an operat-
ing fault the message “CHECK ABS”
appears on the instrument panel along
with the
© warning light.
Consult an approved dealer.
Driver assistance with a
trailer
This system helps to maintain control
over the vehicle while using a trailer.
It detects shaking caused by towing a
trailer under certain driving conditions.
Operating conditions
– The towbar must be approved by an authorised dealer;
– the harness must be approved by an authorised dealer;
– the towbar must be connected to the vehicle.
Operating principle
The function stabilises the vehicle by:
– asymmetric braking of the front wheels to reduce shaking caused by
the trailer;
– braking of all four wheels and limita- tion on engine torque to reduce the
vehicle speed until the shaking has
stopped.
Warning light
 flashes on the in-
strument panel to inform the driver.
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.).

DRIVER CORRECTION DEVICES AND AIDS (5/8)
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, tunnel etc.) ;
– poor weather conditions (snow, hail, black ice, etc.).
Risk of inadvertent braking.
Operating faults
The warning lights
 and 
lit up on the instrument panel accom-
panied by the message “WARNING
AEBSCHECK” indicate a system
fault. Consult an approved dealer.
When the system detects that the func-
tion is not available, the
 warn-
ing light lights up on the instrument
panel and stays on, with the message
“WARNING AEBS DISABLED”.
There are two possibilities:
– The system is temporarily disrupted (for example: radar obscured by
dirt, mud, snow etc.). In this case,
park the vehicle and switch off the
engine. Clean the detection 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.

2.21
DRIVER CORRECTION DEVICES AND AIDS (6/8)
Active emergency braking
Limitation of the system operation
– 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 an
avoidance manoeuvre.
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.

2.24
TYRE PRESSURE LOSS WARNING (1/3)
1
When fitted to the vehicle, this system
notifies the driver if one or more tyres
lose pressure.
Operating principle
Each wheel (except for the emergency
spare wheel) has a sensor in the infla-
tion valve which periodically measures
the tyre pressure while driving.
Warning light
 1 comes on to
alert the driver in the event of insuffi-
cient pressure (deflated wheel, punc-
tured tyre, etc.).
This function is an addi-
tional driving aid.
However, the function does
not take the place of the
driver. It cannot, therefore, under
any circumstances replace the vig-
ilance or the responsibility of the
driver.
Check the tyre pressures, including
the emergency spare wheel, once a
month.
Resetting the standard level
for the tyre pressures
This should be done:
– when the standard tyre pressure needs to be changed to adapt to
usage conditions (empty, carrying a
load, motorway driving, etc.);
– after swapping a wheel (however this practice is not recommended);
– after changing a wheel.
It should always be done after checking
the tyre pressure of all four tyres when
cold.
Tyre pressures must correspond to the
current usage of the vehicle (empty,
carrying a load, motorway driving, etc.).
