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 perform-
ance relating to the road surface and
roadholding. 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.).
These include:
– the ABS
(anti-lock braking
system);
– the electronic stability program
ESC with understeer control and
traction control;
– emergency braking assistance with (depending on the vehicle)
braking anticipation;
– regenerative braking system.
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.

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.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.
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 deacti-
vated.
Consult an approved dealer.

2.17
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
These may light up in the event of rapid
deceleration.
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.
Hill start assistance
This function assists the driver when
starting on hills. It prevents the vehicle
from rolling backwards, depending on
the slope, 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 ) and the vehicle is completely
stationary (brake pedal depressed).
DRIVER CORRECTION DEVICES AND AIDS (3/4)
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 vehi-
cle from rolling backwards.
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.

2.18
Regenerative braking system
When braking, the regenerative brak-
ing system can convert the energy pro-
duced by the vehicle deceleration into
electric energy.
This will recharge the 400V traction bat-
tery and gain greater vehicle range.Operating faults
– © lights up on the instrument
panel, alongside the message
“Check braking system”: braking as-
sistance is available at all times.
Under these conditions, the feel of
applying the brake pedal may be dif-
ferent.
You are recommended to apply
strong continuous pressure to the
pedal.
Please see an authorised dealer.
–
û lights up on the instrument
panel, alongside the message
“Braking system fault”: this indi-
cates a fault in the braking system.
Please call an authorised dealer.
DRIVER CORRECTION DEVICES AND AIDS (4/4)
The û warning light re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions allow.
Switch off the engine and do not
restart it. Contact an Authorised
Dealer.

The speed limiter function helps you
stay within the driving speed limit that
you choose, known as the limit speed.Controls
1 Main “On/Off” switch.
2 Limit speed activation, storage and increase switch (+).
3 Decrease limit speed (-).
4 Speed limiter function standby (with limited speed memory) (O).
5 Activation and recall of stored limit speed (R).
2354
Switching on
Press the side switch 1 . The warn-
ing light
 6 comes on, lit orange, and
the message “Speed limiter” appears
on the instrument panel, accompanied
by dashes to indicate that the speed
limiter function is activated and waiting
to store a limit speed.
To store the current speed, press
switch 2 (+): the limit speed replaces the
dashes and the activation of the speed
limiter is confirmed by the warning light
Ð on an orange background.
The minimum stored speed is 20 mph
(30 km/h).

Varying the limit speed
The limit speed may be changed by re-
peatedly pressing:
– switch 2 (+) to increase speed;
– switch 3 (-) to reduce speed.
The speed limiter function is
in no way linked to the brak-
ing system.
CRUISE CONTROL, SPEED LIMITER: speed limiter (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”).
Exceeding the limit speed
It is possible to exceed the limit speed
at any time. To do this: press the accel-
erator pedal firmly and fully (beyond
the resistance point).
If the speed is exceeded, the limited
speed flashes on the instrument panel
and a beep sounds.
Then, release the accelerator: the
speed limiter 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: the stored speed will flash
on the instrument panel information dis-
play to inform you of this situation.

CRUISE CONTROL, SPEED LIMITER: speed limiter (3/3)
Putting the function on
standby
The speed limiter function is sus-
pended when you press switch 4 (O).
In this case, the speed limit remains
stored and the message “Memorised”
accompanied by this speed appears on
the instrument panel.
Standby is confirmed when the warn-
ing light
Ð on the orange back-
ground goes out and the warning light
 comes on.
Recalling the limit speed
If a speed has been saved, it can be re-
called by pressing switch 5 ((R)).
When the stored speed is recalled, ac-
tivation of the speed limiter is confirmed
by the illumination of the warning light
Ð on an orange background.
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.
Switching off the function
The speed limiter function is deacti-
vated if you press switch 1: in this case
a speed is no longer stored. The warn-
ing light (
 or Ð) on the instru-
ment panel going out confirms that the
function is stopped.

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 additio-
nal driving aid. However,
the function does not take
the place of the driver.
Therefore, it can under no circums-
tances replace the driver’s responsi-
bility 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 cruising speed saved) (O).
5 Activation with recall of stored go-
verned cruising speed (R).
