If the vehicle is equipped with the func-
tion, this system monitors the tyre pres-
sure.
Operating principleEach wheel (except for the emergency
spare wheel) has a sensor in the infla-
tion valve which periodically measures
the tyre pressure. The system informs
the driver via the on-board compu-
ter 1 that the tyres are sufficiently in-
flated and warns if they are underinfla-
ted or leaking. The warning light
comes on to warn the driver if the pres-
sure is too low. 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.).
With the ignition on:
– make short presses on the con-
trol 2 to select the tyre pressure
display (please refer to “On-board
Computer” in Section 1);
– press and hold (around three sec- onds) the control 2 to launch initial-
isation. Flashing tyres followed by
the message “Pressure ref ongoing”
means that the request to learn the
reference pressures has been taken
into account;
– reset can take several minutes of dri- ving.
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 vi-
gilance or the responsibility of the
driver.
Check the tyre pressures, including
the emergency spare wheel, once a
month.
TYRE PRESSURE MONITORING SYSTEM (1/4)
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 wheels over (how- ever this practice is not recom-
mended);
– after changing a wheel.

TYRE PRESSURE MONITORING SYSTEM (2/4)
« Adjust tyre pressure »
A wheel A shown in orange on the dis-
play 4 together with the warning light
indicates a flat tyre.
Check and, if necessary, readjust the
pressures of the four wheels when cold.
While driving the warning light 3
goes off after a few minutes.
DisplayThe display 4 and the warning light 3
on the instrument panel warns
you of any inflation faults (flat tyre,
puncture, system fault, etc.).

A
The sudden loss of pressure in a
tyre (burst tyre, etc.) cannot be de-
tected by the system.For your safety, the warning light ® requires you to stop immedia-
tely as soon as traffic conditions allow.
« Puncture »
The affected wheel A appears red on
the display 4 along with the warning
light 3
and a beep. They indicate
that the affected wheel is punctured
or severely underinflated. Replace it
or contact an authorised dealer if it is
punctured. Top up the tyre pressure if
the wheel is deflated. This message
appears along with the
® warn-
ing light.
« Check tyre pressure sensors »
The affected wheel A is shown in white
on the display 4 together with the
flashing warning light 3
and the
warning light
©. This message ap-
pears when at least one wheel fitted on
the vehicle does not have a sensor (e.g.
emergency spare wheel). Otherwise,
consult an authorised dealer.
2.23
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 the tyre pressures cannot be checked
when they are cold, the recommended
pressures should be increased by 0.2
to 0.3 bar (3 PSI).
Never deflate a hot tyre.
Tyre repair product and
inflation kit
Because the valves are specially desi-
gned, only use equipment approved by
the approved network.
TYRE PRESSURE MONITORING SYSTEM (3/4)
Interchangeability of wheels
If you want to swap the wheels round,
consult an authorised dealer to reinitia-
lise the system.
Each of the sensors incor-
porated in the valves 5 is
dedicated to a single wheel:
under no circumstances
should you swap the wheels, with-
out resetting the system.
There is a risk of incorrect informa-
tion which could have serious con-
sequences.

Replacing wheels/tyres
This system requires specific equip-
ment (wheels, tyres, hubcaps, etc.).
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 to the vehicle,
the message “Check tyre pressure sen-
sors” is displayed on the instrument
panel.
Changing a wheel
The system may take several minutes depending on use for the new
wheel positions and pressures to be recognised; check the tyre pres-
sures after all operations.

DRIVER CORRECTION DEVICES AND AIDS (3/5)
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 control system
are deactivated.
Consult an approved dealer.
Disabling the traction control
system
If the vehicle is fitted with this function,
in some situations (driving on very wet
ground: snow, mud, etc. or driving with
snow chains fitted), the system may
reduce the engine output to limit wheel-
spin. If this is not required, it is possible
to deactivate the function by pressing
switch 1.
The message “Traction control off” is
displayed on the instrument panel to
inform you. The traction control system offers ad-
ditional safety. It is recommended that
you do not drive with the function di-
sabled. Correct this as soon as pos-
sible by pressing the switch
1 again.
Note: the function is reactivated auto-
matically when the ignition is switched
on or when a speed of approximately
24 mph (40 km/h) is exceeded.

DRIVER CORRECTION DEVICES AND AIDS (5/5)
Hill start assistance
This device assists the driver when
starting on hills (ascending or descend-
ing), and the warning light
may
be displayed on the instrument panel. It
prevents the vehicle from rolling back-
wards by automatically applying the
brakes when the driver lifts his/her foot
off the brake pedal to depress the ac-
celerator pedal.
System operation
It only operates when the gear lever is
in a position other than neutral (other
than N or P for automatic transmis-
sions) and the vehicle is completely
stationary (brake pedal depressed)
The system holds the vehicle for ap-
proximately 2 seconds. The brakes are
then released (the vehicle will move ac-
cording to the slope).The hill start assistance
system cannot completely
prevent the vehicle from
rolling backwards in all sit-
uations (extremely steep gradients,
etc.).
In all cases, the driver may depress
the brake pedal to prevent the ve-
hicle from rolling forwards or back-
wards.
The hill start assistance function
should not be used for prolonged
stops: use the brake pedal.
This function is not designed to im-
mobilise the vehicle permanently.
If necessary, use the brake pedal to
stop the vehicle.
The driver must remain particularly
vigilant when driving on slippery or
low-grip surfaces and/or on hills.
Risk of serious injury.

CRUISE CONTROL/SPEED LIMITER: speed limiter function (2/3)
Driving
When a limited speed has been stored
and this speed is not reached, driving is
similar to driving a vehicle without the
speed limiter function.
Once you have reached the stored
speed, no effort on the accelera-
tor pedal will allow you to exceed
the programmed speed except in an
emergency (refer to information on
“Exceeding the limit speed”).
Varying the limit speed
The limit speed may be changed by re-
peatedly pressing:
– switch 3 (+) to increase speed;
– switch 4 (-) to reduce speed.
The speed limiter function is
in no way linked to the brak-
ing system.
Exceeding the limit speed
It is possible to exceed the limit speed
at any moment. To do this: press the
accelerator pedal firmly and fully
(beyond the kickdown point).
The limited speed flashes on the instru-
ment panel and, depending on the ve-
hicle, the display area lights up in red to
inform you that the limit speed is being
exceeded.
Then, as far as is possible, release
the accelerator pedal: the speed lim-
iter function will return as soon as you
reach a speed lower than the stored
speed.
Limited speed cannot be maintained
If driving up or down a steep gradient,
the system is unable to maintain the
limit speed: this speed flashes on the
instrument panel and, depending on
the vehicle, the display area will light up
in red.

CRUISE CONTROL/SPEED LIMITER: cruise control function (3/4)
Putting the function on
standby
The function is suspended when you:
– 5 switch (O);
– depress the brake pedal;
– depress the clutch pedal or shift into neutral if the vehicle has an auto-
matic gearbox.
In these three cases, the cruising
speed remains stored and the mes-
sage “Memorised” accompanied by this
speed appears on the instrument panel.
Switching to standby is confirmed, de-
pending on the vehicle:
– by the disappearance of the
warn-
ing light;
– or by the message area no longer being lit up in green.
Exceeding the cruising speed
The cruising speed may be exceeded
at any time by depressing the accelera-
tor pedal.
The cruising speed flashes on the in-
strument panel and, depending on the
vehicle, the display area lights up in
red to inform you that the limit speed is
being exceeded.
Then, release the accelerator: after a
few seconds, the vehicle will automati-
cally return to its set cruising speed.
Cruising speed cannot be
maintained
If driving up or down a steep gradient,
the system is unable to maintain the
cruising speed: this speed flashes on
the instrument panel and, depending
on the vehicle, the display area will light
up in red.
Adjusting the cruising speed
The cruising speed may be changed by
pressing the following repeatedly:
– switch 3 (+) to increase speed;
– switch 4 (-) to reduce speed.
The cruise control function
is in no way linked to the
braking system.
