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 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 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.

electronic stability control
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.

Disabling the aSR 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.
Traction control (ASR) offers additional
safety; it is recommended that you do
not drive with the function disabled.
Correct this as soon as possible by
pressing 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.

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

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 -
proved Dealer.

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
To vary the limit speed, press switch 2
(+) repeatedly to increase the speed or
switch 3 (-) to decrease it.
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).
Whilst the speed is being exceeded,
the cruising speed displayed on the in-
strument panel flashes.
Then, release the accelerator pedal:
the speed limiter function will return as
soon as you reach a speed lower than
the stored speed. Limited speed cannot be maintained
When driving 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.

in no way linked to the brak-
ing system.

In this case, the limit speed remains
stored and the message "stored" ac -

Recalling the limit speed
If a speed has been stored, it can be re-
called by pressing switch 5 (R).
When the speed limiter is sus -
pended, pressing switches 2 (+)
or 3 (-) reactivates the function with-
out 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 deac -
tivated if you press switch 1 : in this
case a speed is no longer stored. The
orange
instrument panel indicator
light goes out to confirm that the func-
tion is deactivated.

Cruise control
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 Limit speed activation, storage and
decrease switch (-).
4 Switch the function to standby
(with memorised cruising speed)
(O).
5 Cruising speed activation, storage
and recall (R).
