Authorised Dealer.
Anti-lock braking system
(ABS)
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.).
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.
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.
Depending on the vehicle, this is com-
posed of:
– anti-lock braking system (ABS);
– electronic stability program (ESC) with understeer control and trac-
tion control;
– driver assistance with a trailer;
– emergency brake assist;
– grip control;
– hill start assistance.

Operating faults
When the system detects an operating
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.
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.
DRIVING CORRECTION DEVICES AND AIDS (2/5)
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.
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.
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 vigi-
lance or responsibility of the driver
when manoeuvring the vehicle (the
driver must always be ready for
sudden incidents which may occur
when driving).

2.18
DRIVING CORRECTION DEVICES AND AIDS (3/5)
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 operating
fault the message “CHECK ABS” ap-
pears on the instrument panel along
with the
© warning light.
Consult an approved dealer.
Driver assistance with a
trailer
This system helps to maintain control
over the vehicle while using a trailer.
It detects shaking caused by towing a
trailer under certain driving conditions.
Operating conditions
– the towbar must be approved by an authorised dealer;
– the harness must be approved by an authorised dealer;
– the towbar must be connected to the vehicle.
Operating principle
The function stabilises the vehicle by:
– asymmetric braking of the front wheels to reduce shaking caused by
the trailer;
– braking of all four wheels and limita- tion on engine torque to reduce the
vehicle speed until the shaking has
stopped.
Warning light
 flashes on the in-
strument panel to inform the driver.

DRIVING CORRECTION DEVICES AND AIDS (5/5)
Hill start assistance
Depending on the gradient of the in-
cline, this system assists the driver
when starting on a hill. It prevents the
vehicle from rolling backwards, de-
pending on the slope, by automatically
applying the brakes when the driver
lifts his/her 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 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.

2.30
CRUISE CONTROL (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. The func-
tion 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 slip-
pery roads (black ice, aquaplan-
ing, gravel) and during bad weather
(fog, rain, side winds etc.).
There is a risk of accidents.
Controls
1 Cruising speed activation, storage and increase switch (+).
2 Cruising speed decrease switch (-).
3 Switch the function to standby (with stored cruising speed) (O).
4 Activation with recall of stored gov- erned cruising speed (R).
5 Main “On/Off” switch.

Switching off the function
The cruise control function is deacti-
vated if you press switch 5: in this case
a speed is no longer memorised.
The
 and  indicator lights on the
instrument panel go out, confirming that
the function is deactivated.
Recalling the cruising speed
If a speed is memorised, it can be re-
called, once you are sure that the road
conditions are suitable (traffic, road sur-
face, weather conditions, etc.).
With a vehicle speed above 20 mph
(30 km/h), press switch 4 (R).
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 is set to
standby, pressing switch 1 (+) re-
activates 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.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.

Putting the function on
standby
The function is set to standby if you:
– press button 3 (O);
– 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
remains stored and the message
“SPEED MEMORY” appears on the in-
strument panel.
Standby is confirmed when the green
 indicator light goes out.

– With the brake pedal depressed, push the selector lever forwards then
release it.
– Release the brake pedal and accel- erate gently to move forwards. Reverse gear
(vehicle stationary)
– Brake pedal depressed. Push the
selector lever towards the right and
to the rear as shown on the base
of the lever, and then release it.
Reverse gear is engaged and the
letter R appears on the display.
– Release the brake pedal: – the engine’s idle speed is suffi-
cient for parking manoeuvres;
– accelerate gently to reverse.
You may shift from reverse gear to a
forwards gear by pushing the lever for-
wards once the vehicle is stationary.
Note: when the vehicle is stationary,
you must depress the brake pedal to
engage or disengage a gear. Otherwise,
warning light 5 will come on.

Exactly like a vehicle equipped with a manual gearbox, a vehicle equippe\
d
with a sequential gearbox is unable to prevent the vehicle from rolling \
on
a slope if the handbrake is not applied or the brake pedal constantly de\
-
pressed.

2.44
SEQUENTIAL GEARBOX (3/6)
Operation in semiautomatic
mode (manual)
This mode can be activated at any time
when driving by pushing the lever to the
left. The mode is switched without shift-
ing up a gear.
You can initiate gear changes using the
selector lever.
To shift up a gear, push the selector
lever forwards; the accelerator pedal
does not have to be lifted.
To shift down a gear, push the selector
lever backwards; the accelerator pedal
does not have to be lifted. The system will not tolerate a series
of up or down changes that cause the
engine to underrev or overrev.
By pushing the lever forwards twice
you can move up two gears at a time
(except if underrevving). By pushing
the lever backwards twice you can
move down two gears at a time (unless
this causes overrevving).
When decelerating with the foot off
the pedal, the gears will automatically
drop to the low engine speed limit to
avoid stalling. First gear automatically
shifts below a certain speed limit. You
can stop the vehicle at red lights or
junctions etc. by depressing the brake
pedal; there is no need to change to
neutral (N).
The vehicle will move off again:
– either slowly, if you release the brake
without accelerating (e.g. when in a
traffic jam);
– or quickly, if you release the brake and accelerate.
Note: neutral may only be selected
when the vehicle is being driven or is
stationary when the brake pedal is
depressed (if you forget, warning
light 5 will come on) .
Push the gear selector lever to the right
to engage neutral.
If the engine speed is too high or too
low, the system will choose the opti-
mum gear.
Semiautomatic mode can be deacti-
vated and reactivated at any time when
the engine is running by pushing the
lever to the left.

2.45
SEQUENTIAL GEARBOX (4/6)
Operation in automatic mode
Automatic mode is selected by default
every time the ignition is switched on.
The letter A appears on the display.
The vehicle is controlled using the ac-
celerator and the brake. Gears will
change automatically at the correct
moment and at a suitable engine speed
because the automatic mode takes the
road surface and the chosen driving
style into consideration.
Gears may be shifted manually in this
mode. Pushing the lever forwards
or backwards shifts a gear upwards
(except if there is a risk of underrev-
ving) or downwards (except if there is a
risk of overrevving).
Note:
Automatic mode takes account of:
– the position and speed of depression of the accelerator pedal to assess
driving style and select the optimum
gear;
– action on the brake pedal, to com- mence engine braking in preparation
for a downshift.
You can stop the vehicle at red lights,
with the gear engaged, by depressing
the brake pedal; there is no need to
change to neutral (N).
The vehicle will move off again:
– either slowly, if you release the brake without accelerating (e.g. when in a
traffic jam);
– or quickly, if you release the brake and accelerate.
The oil level in the automatic gear-
box system reservoir varies depend-
ing on use. Adding oil is strictly
forbidden (except by qualified ap-
proved network personnel).
