DRIVING CORRECTION DEVICES AND AIDS (1/4)
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.).
Depending on the vehicle, they will con-
sist of:
– ABS (anti-lock braking system) ;
– ESC
(electronic stability control)
with understeer control and trac-
tion control;
– emergency brake assist;
– 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).
Operating faults:
–
© and x lit up on the in-
strument panel alongside mes-
sages “Check ABS”, “Check braking
system” and “Check ESC”: indicates
the ABS, ESC and 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.
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.
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 approved
Dealer.

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.
DRIVING CORRECTION DEVICES AND AIDS (2/4)
Operating faults
When the system detects an operat-
ing fault the message “Check ESC” and
warning light
© and  appear
on the instrument panel.
In this case, the ESC and traction con-
trol system are deactivated. Consult an
authorised dealer.

2.33
DRIVING CORRECTION DEVICES AND AIDS (3/4)
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 assistThis system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
Operating principle
The system detects an emergency
braking situation. In this case, the brak-
ing assistance immediately develops
maximum power and may trigger ABS
regulation. ABS braking is maintained
as long as the brake pedal is not re-
leased.
Hazard warning lights illumination
Depending on the vehicle, these may
light up in the event of sudden decel-
eration.
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).
Deactivating the function
(depending on vehicle)
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 “ESC off” is displayed on
the instrument panel to inform you.

DRIVING CORRECTION DEVICES AND AIDS (4/4)
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 by au-
tomatically 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 (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 released (the vehicle will move ac-
cording 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.

2.37
TRANSMISSION: 4-wheel drive (4WD) (3/4)
Electronic stability program and
traction control when driving off-
road
When driving on soft ground (sand,
mud, deep snow), we recommend that
you deactivate the ESC function by
pressing the “ESC” switch.
In this case, only individual wheel brak-
ing remains active. This function ap-
plies the brake to any wheel that is slip-
ping, allowing the engine torque to be
transferred to the wheels with the most
grip. This is particularly useful when
crossing a bridge.
All the ESC functions will be reacti-
vated when the vehicle speed reaches
approximately 31 mph (50 km/h)
(24.8 mph [40 km/h] in 4WD Lock
mode), when the engine is restarted
or when the “ESC” switch is pressed
again.Operating faults
If the system detects an operating fault,
it automatically switches to “2WD”
mode. The message “Check 4WD” is
displayed on the instrument panel, and
the
‘ and © warning lights
come on.
Drive as soon as possible at a moder-
ate speed to an approved dealer.
For certain operating faults, the system
may not be able to switch to “2WD” or
"4WD Lock” mode. “AUTO” mode re-
mains active.
Contact an approved dealer as soon as
possible.
After stopping the engine, the system
may take up to five minutes to cool
down.
If the system detects excessive wheel-
spin on the front wheels, it adapts the
engine to run in a way that reduces
wheelspin.
Anti-lock braking in
LOCK mode
When “4WD Lock” mode is active, the
ABS switches to off-road mode. In this
case, the wheels may lock intermit-
tently to achieve better grip, thus reduc-
ing braking distances on soft ground.
When this mode is active:
– the vehicle’s manoeuvrability is lim- ited during braking. This operating
mode is therefore not recommended
in very low-grip conditions (eg. ice).
– there may be some noise. This is normal, and does not indicate an op-
erating fault.

2.40
Activating or deactivating the
system
For vehicles fitted with a navigation
system
On the multifunction screen 5, select
the “Vehicle” menu, “Driving assist-
ance”, and “Active braking”, and then
choose “ON” or “OFF”.

Operation
While driving (at speeds of between 20
and 85 mph (30 and 140 km/h)), if there
is a risk of collision with the vehicle in
front, the warning light 4 will be dis-
played on the instrument panel in red,
alongside a beep.
If the driver depresses the brake pedal
and the system still detects a risk of
collision, the brake force is increased. If
the driver fails to react following an alert
of an imminent collision, the system ac-
tivates the brakes.
System A
Operating principle
Using the radar sensor, the system cal-
culates the distance separating the ve-
hicle from the one in front and alerts the
driver if there is a risk of a front-end col-
lision. The driver can then brake the ve-
hicle to limit the damage arising from a
collision.
Note: make sure that the radar sensor 1
is not obscured (by dirt, mud, snow etc.
or by the fitting of accessories such as
bullbars).4

– With the vehicle at a standstill, press and hold the switch 7 OK to access
the settings menu,
– repeatedly press the control 8 up or
down until you reach the “Driving as-
sistance” menu. Press the switch 7
OK;
– repeatedly press control 8up or down
until you reach the “Active braking”
menu, then press the switch 7 OK.
ACTIVE EMERGENCY BRAKING (3/11)
Operating faults
When the system detects an operating
fault, the
 warning light lights up
on the instrument panel, with the mes-
sage “Active braking disconnected”.
There are two possibilities:
– the system is temporarily disrupted (for example: radar obscured by
dirt, mud, snow etc.). In this case,
park the vehicle and switch off the
engine. Clean the detection zone of
the radar. When you next start the
engine, the warning light and the
message go out
– if this is not the case, this may arise from another cause; contact an
Approved Dealer.
Consult an approved dealer.
Press the switch 7
OK again to activate
or deactivate the function:= function activated
< function deactivated
The warning light
 is displayed on
the instrument panel when the system
is deactivated. This system is reacti-
vated each time the ignition is switched
on.
Conditions for non-activation
of the system
The system cannot be activated:
– when the gear lever is in neutral;
– when the parking brake is activated;
– while cornering.
– For 4-wheel drive vehicles, when Electronic Stability Programme
(ESC) with understeer and trac-
tion control are deactivated (please
see “Electronic Stability Programme
(ESC) with understeer and trac-
tion control” above). Warning light
comes on.The system A only detects vehicles
driving in the same direction of traf-
fic. The system cannot detect mo-
torcycles because of the difficulty in
forecasting their trajectory.

2.43
ACTIVE EMERGENCY BRAKING (5/11)
Limitation of the system operation
– The system will only respond to vehicles which are moving or which have \
been sensed as moving.
– The radar area should be kept clean and free of any modifications in ord\
er to ensure the proper operation of the
system.
– The system cannot respond to small vehicles such as motorbikes, bicycles\
or pedestrians as effectively as to other vehicles.
– The system may not operate properly when the road surface is slippery (\
rain, snow, black ice etc.).
Deactivating the function
You must disable the function if:
– the brake lights are not functioning;
– the front of the vehicle has undergone an impact or been damaged;
– the vehicle is being towed (breakdowns);
Halting the function
You can halt the active braking function at any time by tapping the accel\
erator pedal or by turning the steering wheel in a avo id-
ance manoeuvre.
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.

2.44
ACTIVE EMERGENCY BRAKING (6/11)
System B
Operating principle
Using information from the radar-cam-
era, the system calculates the distance
which separates it from the vehicle in
front and the surrounding pedestrians.
It notifies the driver if there is a risk of
head-on collision. The driver can then
brake the vehicle to limit the damage
arising from a collision.
Note: make sure the windscreen is not
obscured (dirt, mud, snow, condensa-
tion etc.).
This function is an addi-
tional driving aid. This func-
tion is not under any circum-
stances intended to replace
the due care and attention of the
driver, who should at all times be
in control of the vehicle.This system applies maximum
braking to the vehicle
For safety reasons, always wear
your seat belt when travelling in
your vehicle and make sure that it
is loaded so that no items can be
thrown forward and hit the occu-
pants.
9
Detection of pedestrians
Operation
When driving (speed between
about 4.2 mph (7 km/h) and 36 mph
(60 km/h)), if there is a risk of impact
with a pedestrian, the indicator 9 is dis-
played in red on the instrument panel
and accompanied by a beep.
When the impact is imminent, the
system activates the braking.
The system can apply maximum brak-
ing.

2.45
ACTIVE EMERGENCY BRAKING (7/11)
System B (continued)
Detection of vehicles
Operation
When driving (speed between about
4.34 and 99.2 mph (7 and 160 km/h)), if
there is a risk of collision with the vehi-
cle in front, the system:
– warns you of a collision risk:
The indicator 4 is displayed in red
on the instrument panel and accom-
panied by a beep.
If the driver depresses the brake
pedal and the system still detects a
risk of collision, the brake force is in-
creased.
– triggers braking:
if the driver fails to react following the alert and collision becomes im-
minent.
4
You can interrupt braking at any
point by:
– tapping the accelerator pedal;
or
– turning the steering wheel in an avoidance manoeuvre.
Special features
When the vehicle speed:
– is less than 27.9 mph (45 km/h) ap-
proximately, the warning and brak-
ing are activated at the same time;
– is between about 27.9 mph
(45 km/h) and 48 mph (80 km/h)
approximately, the warning is acti-
vated. Braking will only be triggered if
the vehicle preceding you is moving.
Braking is not activated for stationary
vehicles;
– is between about 48 mph (80 km/h)
and 99.2 mph (160 km/h) , the warn-
ing and braking are only triggered if
the vehicle preceding you is moving.
The warning and braking are not ac-
tivated for stationary vehicles;
– is above 99.2 mph (160 km/h), the
system is not active.
