TYRE PRESSURE LOSS WARNING (5/9)
SYSTEM A (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 should be increased
by 0.2 to 0.3 bar (3 PSI).
Never deflate a hot tyre.
After each reinflation or readjustment of
the tyre pressure, launch the reinitiali-
sation of the tyre pressure reference
value.
Replacing wheels/tyres
Only use equipment approved by the
brand network, or the system risks
being activated late or not operating
correctly. Please see the information on
“Tyres” in Section 5.
After each change of wheel/tyre, read-
just the tyre pressure and launch the
reinitialisation of the tyre pressure ref-
erence value. Tyre repair product and inflation kit
Only use equipment approved by the
brand network, or the system risks
being activated late or not operating
correctly. Please refer to “Tyre inflation
kit” in Section 5.
After using the tyre inflation kit, readjust
the tyre pressure and launch the reini-
tialisation of the tyre pressure reference
value.

2.21
TYRE PRESSURE LOSS WARNING (6/9)
SYSTEM B
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, punctu-
red tyre, etc.).

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.).
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.

With the ignition on, depending on the vehicle:
– repeatedly press button 2 or 3 to
select the “SET
” warning light
on the display B;
– press and hold (around 3 seconds) button 2 or 3 to start initialisation. When the “SET” warning light flashes
for around five seconds, this indicates
that the reset request for the tyre pres-
sure reference value has been taken
into account.
Reinitialisation is carried out after a few
minutes’ driving.
Note: the standard tyre pressure
cannot be less than that recommended
and indicated on the door frame.
Or
– repeatedly press the button 2
to
select the “SET
” warning light
on the display B;
– press and hold (around 3 seconds) the button 2 to start initialisation. The
flashing, lasting around five seconds,
followed by a constant display of the
“SET
” indicates that the reset
request for the tyre pressure refer-
ence value has been taken into ac-
count.

TYRE PRESSURE LOSS WARNING (8/9)
SYSTEM B (cntd.)
Inflate tyres
The
 1 warning light comes on
(not flashing).
This indicates that at least one tyre is
flat.
Check and, if necessary, readjust the
pressures of the four wheels when cold.
The warning light
 1 goes off after
a few minutes’ driving.
The sudden loss of pressure in a
tyre (burst tyre, etc.) cannot be de-
tected by the system.
Puncture
Warning light
 1 comes on steady,
accompanied by a beep and warning
light
®.
They indicate that at least one wheel
is punctured or severely underinfla-
ted. Replace it or contact an authorised
dealer if it is punctured. Top up the tyre
pressure if the wheel is deflated.
Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions
allow.
Check tyre sensors
The warning light
 1 flashes for
several seconds, then stays on, along
with the warning light
©.
These indicate that at least one of the
sensors is defective or missing. In other
cases, contact an authorised dealer.

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.

2.26
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.

2.27
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.
However, 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 vigilance or responsibil-
ity of the driver when manoeuvring
the vehicle (the driver must always
be ready for sudden incidents which
may occur when driving).

2.29
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.

2.30
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.

CRUISE CONTROL/SPEED LIMITER: speed limiter function (3/3)
Recalling the limit speed
If a speed has been saved, it can be re-
called by pressing switch 4 ((R)).
Putting the function on
standby
The speed limiter function is suspended
when you press switch 5 (O). In this
case, the limit speed remains stored
and the message “ MEM” accompanied
by this speed appears on the instru-
ment panel.
Switching off the function
The speed limiter function is deac-
tivated if you press switch 1 : in this
case a speed is no longer stored. The
orange instrument panel warning light
 goes out, confirming that the func-
tion is stopped.
When the speed limiter is put on
standby, pressing switch 2 (+) re-
activates the function without taking
into account the stored speed: it is
the speed at which the vehicle is
moving that is taken into account.
