special note:
– If the dipped beam headlights are
manually switched on and if the light
is sufficient, the directional head -
lights will remain fixed;
– If the lights come on automatically
when cornering, the directional
headlights will start working from the
next time the vehicle corners;
– When the dipped beam headlights
are switched on with the engine
running and the vehicle stationary,
the lights move to reinitialise them -
selves. If not, there is a system fault.
switching off the lights
There are two possibilities:
– Manually, move ring 2 to position 0;
– automatically, the lights will go out
when the engine is switched off, the
driver’s door is opened or the vehicle
is locked. In this case, the next time
the engine is started the lights will be
switched back on according to the
position of the ring 2.
“see-me-home lighting”
function
This function allows you to briefly switch
on the dipped beam headlights (to pro-
vide light when opening a gate, etc.).
With the engine and lights off and
ring 2 in position 0, pull stalk 1 towards
you: the dipped beam headlights come
on for approximately thirty seconds.
To increase this duration, you may pull
the stalk up to four times (total time re-
stricted to two minutes). The message
“lighting for_ _ _” along with the times
the lights will be on for is displayed on
the instrument panel to confirm this
action.
To switch off the lights before they go
out automatically, turn ring 2 to any po-
sition, then return it to position 0.
directional headlights
Depending on the vehicle, with the
dipped beam headlights on and under
certain conditions (speed, steering
wheel angle, forwards gear selected,
etc.) when cornering, the dipped beam
headlights move to light the inside of
the bend.
Operating faults
When the message “check lighting” ap-
pears on the instrument panel along
with warning light
©, this indicates
that there is a lighting fault.
Consult an approved dealer.

to move the steering wheel while
pressing the start button 1 to assist
in unlocking the steering column;
the message “Turn steering wheel +

Special note: if starting the engine
when the outdoor temperature is very
low (below - 10 ° C): hold down the
clutch pedal until the engine starts.

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.).
Driver correction devices and aids
DRIveR CoRReCtIoN DevICeS aND aIDS (1/5)
Depending on the vehicle, they may
comprise:
– t h e a bS ( a n t i - l o c k b r a k i n g
system);
– eSC (electronic stability program)
with understeer control and a SR
traction control;
– emergency brake assist with, de -
pending on the vehicle, braking
anticipation;
– rear wheel steering.
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).
Yo u r b r a k i n g s y s t e m s
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:

the ABS, ESC and emergency brake
assist are deactivated. braking is
always enabled;

eSC with understeer control
and traction control aSR
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, warning 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).
t raction control (aSR)
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 ASR are deactivated.
Consult an approved dealer.

Rear wheel steering
On equipped vehicles, this system,
when the vehicle is being driven, steers
the rear wheels according to driving
conditions: at low speed this system
offers manoeuvrability, at higher speeds
it optimises stability.
When driving at low speeds, the rear
wheels steer in the opposite direction to
the front wheels (figure A ) to increase
the vehicle’s manoeuvrability. This is
used when driving in towns, on winding
roads, during parking manoeuvres, etc.
When driving at speeds above 40 mph
(60 km/h), the rear wheels steer in the
same direction as the front wheels
(figure B) to optimise the vehicle’s sta-
bility. This is useful when changing
lanes or when cornering etc. operating faults
–
If the
© warning light, together
with the message “ Check power
steering ”, is displayed on the instru-
ment panel: please contact an au -
thorised dealer.
– If the warning light
®, together
with the message “ Power steering
fault”, is displayed on the instrument
panel, this indicates a fault in the
system.

® requires you to stop
as soon as traffic conditions
allow. Contact an approved
Dealer.
An impact to the underside of the
vehicle (e.g.: striking a post, raised
kerb or other street furniture) may
result in damage to the vehicle (e.g.:
deformation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap -
