SYSTEM B (cntd.)
Readjustment of tyre pressures
The tyre pressures must be adjusted
when cold (please refer to the label lo-
cated on the edge of the driver’s door).
If tyre pressures cannot be checked
when the tyres are cold, the recom-
mended pressures must be increased
by 0.2 to 0.3 bar (3 PSI).
Never deflate a hot tyre.
TYRE PRESSURE LOSS WARNING (9/9)
Replacing wheels/tyres
This system requires specific equip-
ment (wheels, tyres, hubcaps, etc.).
Please see the information on “Tyres”
in Section 5.
Contact an approved Dealer to fit new
tyres and to find out about available ac-
cessories compatible with the system
and available from your dealer net-
work: the use of any other accessory
could affect the correct operation of the
system or damage a sensor.
Emergency spare wheel
If the vehicle is equipped with an emer- -
gency spare wheel, it will not have a
sensor. When it is fitted on the vehicle,
the warning light
 flashes for sev-
eral seconds, then stays on, together
with the warning light
©.
Tyre repair product and inflation kit
Because the valves are specially desi-
gned, only use equipment approved by
the approved network. Please refer to
“Tyre inflation kit” in Section 5.

2.27
Electronic stability control
(ESC) with understeer
control, traction control and
assistance with side winds
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.).
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.
DRIVER CORRECTION DEVICES AND AIDS (2/4)
Understeer control
This system optimises the action of the
ESC in the case of pronounced under-
steer (loss of front axle road holding).
Assistance with side winds
This system optimises the action of the
ESC and also helps to control the vehi-
cle in case of variation of side winds.
It helps maintain the vehicle trajectory
through the use of the brakes.
If the system is activated, the indicator
light
 may flash on the instrument
panel.
Traction control
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
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 warning lights
© and
 appear on the instrument panel.
In this case, the ESC and traction con-
trol system are deactivated.
Consult an approved dealer.

2.28
DRIVER CORRECTION DEVICES AND AIDS (3/4)
Emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
The system allows an emergency brak-
ing situation to be detected when the
brake pedal is pressed. In this case, the
braking assistance immediately devel-
ops maximum power and may trigger
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.
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 operating
fault, the warning light
© comes
on on the instrument panel.
Consult an approved dealer.
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).

2.30
LANE DEPARTURE WARNING (1/2)
This lane departure warning system no-
tifies 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 a driving aid in the event of the accidental crossing o\
f
a continuous or broken line in the road. However, the function is not in-
tended to replace the driver. The function can be disrupted under certain
conditions, including:
– poor visibility (rain, snow, fog, dirty windscreen, glare of the sun, partially obs- cured road lines, etc.);
– roads with tight bends;
– closely following a vehicle in the same lane;
– worn road markings, difficult to distinguish or spaced very widely apart;
– narrow roads;
– ...
In this case, warning light
 on the instrument panel goes out to indicate that
the function will not operate (lines not detected).
Under no circumstances should this function replace the driver’s care or res-
ponsibility whilst performing manoeuvres.

2.31
LANE DEPARTURE WARNING (2/2)Deactivation
Press the switch 1. The warning light 2
in the switch 1 goes out.
Operating faults
In the event of a malfunction, the warn-
ing light on the button 1 remains off,
and warning lights
© and 
come on on the instrument panel along-
side a beep. Please consult an autho-
rised dealer.
When a line is crossed and the indica-
tors have not been activated, the func-
tion alerts the driver through warning
light
 on the instrument panel,
and a beep.
Conditions for non-activation
of alerts
– Indicators activated or having been activated less than approximately
four seconds prior to departing from
the lane;
– Very fast lane departure;
– Driving continuously on a line;
– On bends, the function allows for slightly cutting the bend;
– dirt covering the windscreen camera;
– ...
ActivationPress the switch 1: the warning light 2
integrated on the switch 1 comes on.

Driving
Once a cruising speed is memorised
and the cruise control function is active,
you may lift your foot off the accelera-
tor pedal.
Please note that you must
keep your feet close to the
pedals in order to react in
an emergency.
Activating cruise control
At a steady speed (above 18 mph (30
km/h approximately)) press switch 2
or (+): the function is activated and the
current speed is saved.
The cruising speed replaces the dashes
and the cruise control is confirmed by
the appearance of warning light 6 lit
green, as well as warning light 7.
Switching on
Press switch 1 side .
Indicator light 7 comes on, lit green,

Switching off the function
The cruise control function is deacti-
vated if you press switch 1: in this case
a speed is no longer stored. The two in-
strument panel warning lights
 and
 go out to confirm that the function is
deactivated.
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
4 (R) if the vehicle speed is
above 20 mph (30 km/h).
When the stored speed is recalled, acti-
vation of the cruise control is confirmed
by the illumination of the
 warning
light.
NB: if the speed previously stored is
much higher than the current speed,
the vehicle will accelerate more rapidly
to reach this threshold.
When the cruise control function is
put on standby, pressing switch 2
(+) reactivates the cruise control
function without taking into account
the stored speed: it is the speed at
which the vehicle is moving that is
taken into account.
Putting the function on
standby
The function is set to standby if you:
– use the switch 5 (O);
– the brake pedal;
– depress the clutch pedal or the shift into neutral if the vehicle has an au-
tomatic gearbox.
In all three cases, the cruising speed re-
mains stored and the message “ MEM”
appears on the instrument panel.
Standby is confirmed when indicator
light
 goes out.
CRUISE CONTROL (4/4)
Putting the cruise control
on standby or switching it
off does not cause a rapid
reduction in speed: you
must brake by depressing the brake
pedal.
