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.

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

– 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.

2.47
ACTIVE EMERGENCY BRAKING (9/11)
System B (continued)
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.
As a general rule, if the driver shows
signs of attention (action on the steering
wheel, pedals etc.), the system delays
its operation or does not activate.
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”.
Consult an approved dealer.
Temporarily not available
When the system detects a tempo-
rary unavailability, the
 warning
light lights up on the instrument panel
accompanied by the message “Active
braking: sensor blind” or, depending on
the vehicle, “Radar-camera: no visibil-
ity”.
The possible causes are:
– the system is temporarily blinded (glare from the sun, dipped beam
headlights, bad weather conditions
etc.). The system will be operational
again when visibility conditions are
better.
– The system is temporarily disrupted (for example: windscreen obscured
by dirt, ice, snow etc.). In this case,
park the vehicle and switch off the
engine. Clean the windscreen. When
you next start the engine, the warn-
ing light and the message go out.
– If this is not the case, this may arise from another cause; contact an
Approved Dealer.

2.49
ACTIVE EMERGENCY BRAKING (11/11)
Limitation of the system operation
– A vehicle travelling in the opposite direction will not trigger any alert\
or any action on the system operation.
– The radar-camera area on the windscreen should be kept clean and free of\
any modifications in order to ensure the
proper operation of the system.
– The system cannot respond to small vehicles such as motorbikes or bicycl\
es as effectively as to other vehicles.
– The system may not operate properly when the road surface is slippery (\
rain, snow, black ice etc.).
– To ensure correct operation, System B needs to distinguish the complete outline of the pedestrian. So the sys\
tem cannot
detect:
- Pedestrians in the darkness or in poor lighting conditions;
- Partially visible pedestrians;
- Pedestrians less than approximately 80cm tall;
- Pedestrian carrying large objects;
Deactivating the function
You must disable the function if:
– the brake lights are not functioning;
– the area of the radar-camera has been damaged (on the windscreen side o\
r the interior rear-view mirror side);
– the vehicle is being towed (breakdowns);
– the windscreen is cracked or distorted (do not carry out repairs on thi\
s area of the windscreen; have it changed by an Authorised Dealer).
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.
