DRIVER CORRECTION DEVICES AND AIDS (1/4)
Depending on the vehicle, this is com-
posed of:
– the ABS (anti-lock braking
system);
– electronic stability control ESC
with understeer control and trac-
tion control;
– emergency brake assist with, de- pending on the vehicle, braking
anticipation;
– hill start assistance.
In an emergency, apply firm and
continuous pressure to the brake
pedal. There is no need to pump
it repeatedly. The ABS will modu-
late the force applied in the braking
system.
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).
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.
Operating faults:
–
© and x lit on the instru-
ment panel with the messages
“Check ABS”, “Check braking
system” and “Check ESC” : ABS,
ESC and the emergency brake
assist are deactivated. Braking is
always enabled;
–
x, D, © and ® lit
up on the instrument panel alongside
the message “Braking system fault”:
this indicates a fault in the braking
system.
In both cases, consult an approved
Dealer.
ABS (anti-lock braking
system)
Under heavy braking, the ABS prevents
the wheels from locking, allowing the
stopping distance to be managed and
keeping control of the vehicle.
Under these circumstances, the vehi-
cle can be steered to avoid an obstacle
whilst braking. In addition, this system
can increase stopping distances, par-
ticularly on roads with low surface grip
(wet ground etc.).
You will feel a pulsation through the
brake pedal each time the system is
activated. The ABS does not in any
way improve the vehicle’s physical per-
formance relating to the road surface
and road-holding. It is still essential to
follow the rules of good driving practice
(such as driving at a safe distance from
the vehicle in front, etc.).

DRIVER CORRECTION DEVICES AND AIDS (2/4)
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
© appear on the in-
strument panel.
In this case, the ESC and traction
control system are deactivated. Consult
an authorised dealer.

2.26
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.
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 brak-
ing system” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.
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.
Special cases
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.
DRIVER CORRECTION DEVICES AND AIDS (3/4)
Disabling the traction control
system
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.

DRIVER CORRECTION DEVICES AND AIDS (4/4)
Hill start assistance
This device assists the driver when
starting on hills (ascending or descend-
ing). It prevents the vehicle from rolling
forwards or backwards by automatically
applying the brakes when the driver lifts
their foot off the brake pedal to depress
the accelerator 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 gradually released (the vehicle will
move according 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: cruise control function (1/4)
The cruise control function helps you to
maintain your driving speed at a speed
that you choose, called the cruising
speed.
This cruising speed may be set at any
speed above 20 mph (30 km/h).
The cruise control function
is in no way linked to the
braking system.
This function is an addi-
tional driving aid. However,
the function does not take
the place of the driver.
Therefore, it can under no circum-
stances replace the driver’s respon-
sibility to respect speed limits and to
be vigilant (the driver must always
be ready to brake). Cruise control
must not be used in heavy traffic, on
undulating or slippery roads (black
ice, aquaplaning, gravel) and during
bad weather (fog, rain, side winds
etc.).
There is a risk of accidents.
Controls
1 Main “On/Off” switch.
2 Limit speed activation, storage and
increase switch (+).
3 Decrease cruising speed (-).
4 Switch the function to standby
(with memorisation of the gov-
erned cruising speed) (O).
5 Activation with recall of stored gov-
erned cruising speed (R).

Putting the function on
standby
The function is suspended when you:
– press switch 4 (O);
– depress the brake pedal;
– depress the clutch pedal or shift into neutral if the vehicle has an auto-
matic gearbox.
In all three cases, the cruising speed re-
mains stored, it is no longer displayed in
zone 6 and the message “Memorised”
along with the stored speed will appear
on the instrument panel.
Standby is confirmed when zones A, B
and C go out.
Exceeding the cruising speed
The cruising speed may be exceeded
at any time by depressing the acceler-
ator pedal. The cruising speed flashes
on the instrument panel along with the
illumination of zone C in red.
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: the stored speed on the
instrument panel will flash and zone C
will light up in red to inform you of this
situation.
CRUISE CONTROL/SPEED LIMITER: cruise control function (3/4)
Adjusting the cruising speed
The cruising speed may be changed by
pressing the following repeatedly:
– switch 2 (+) to increase the speed;
– switch 3 (-) to decrease the speed.
The cruise control function
is in no way linked to the
braking system.

CRUISE CONTROL/SPEED LIMITER: cruise control function (4/4)
Note: 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 func-
tion without taking into account the
stored speed: it is the speed at
which the vehicle is moving that is
taken into account.
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 instru-
ment panel green indicator light 7 and
zones A , B and C go out, confirming
that the function is deactivated.
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.

Returning to the cruising speed
If a speed is stored, it can be recalled,
once you are sure that the road condi-
tions are suitable (traffic, road surface,
weather conditions, etc.).
Press switch 5 (R) if the vehicle speed
is above 20 mph (30 km/h).
When recalling the stored speed
zone A lights up to confirm activation.
Zone B lights up as soon as the cruis-
ing speed is reached.

Selector lever 1
Display 3 on the instrument panel
shows the mode and gear selected.
4: P: park
5: R: reverse gear
6: N: neutral
7: D: automatic mode
8 : manual mode
9: zone displaying gearbox mode or
gear engaged in manual mode
Operation
With the gear lever 1 in position P,
switch on the ignition.
To move out of position P, you must de-
press the brake pedal before pressing
unlocking button 2.
With the foot on the brake pedal (warn-
ing light
c on the display 3 goes out),
move the lever out of position P.
Only engage D or R when the vehi-
cle is stopped, with your foot on the
brake and the accelerator pedal re-
leased.
AUTOMATIC TRANSMISSION (1/3)
Driving in automatic mode
Select position D. In most traffic con-
ditions, you will not have to touch the
gear selector lever again: the gears will
change automatically at the right time
and at the most suitable engine speed
because the automatic system takes
into account the vehicle load and road
contour and adjusts itself to the particu-
lar driving style you have chosen.
Economical driving
When driving, always leave the lever
in position D, keeping the accelerator
pedal lightly depressed to ensure auto-
matic gear changes at a lower engine
speed.
Accelerating and overtaking
Depress the accelerator pedal firmly
and fully (so that it goes beyond the
kickdown point).
This will enable you to change down
to the optimum gear within the
engine range.
