DRIVER CORRECTION DEVICES AND AIDS (6/12)
If the driver depresses the brake pedal
and the system still detects a risk of col-
lision, the brake force is increased.
If the driver fails to react following
an alert of an imminent collision, the
system activates the brakes.
Active emergency braking
Using the sensor 1, the system calcu-
lates the distance separating the vehi-
cle 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 sensor 1 is
not obscured (by dirt, mud, snow, etc.).
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, warning light 2 will be displayed
on the instrument panel in red and, de-
pending on the vehicle, on the head-up
display, alongside a beep.
The system 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.

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.
DRIVER CORRECTION DEVICES AND AIDS (10/12)
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 function should be activated by an authorised dealer;
– the towbar must be approved by an authorised dealer;
– the wiring must be approved by an authorised dealer;
– the towbar must be connected to the vehicle.
If the towbar wiring is
plugged in but no trailer
is attached (bicycle car-
rier, luggage carrier with
lighting, etc.), the function may act
under certain rutted road conditions.
Risk of vehicle deceleration.

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 higher speeds, the rear
wheels steer in the same direction as
the front wheels (figure B
) to optimise
the vehicle’s stability. This is useful
when changing lanes or when corner-
ing etc.
Note: The system configuration (agil-
ity, etc.) depends on the mode selected
in the “Multi-Sense” menu (please refer
to the information on “Multi-Sense” in
Section 2). 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.
DRIVER CORRECTION DEVICES AND AIDS (12/12)
AB
® 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-
proved Dealer.

BLIND SPOT WARNING (1/3)
This system alerts the driver to other
vehicles in the detection zone A.
The system is activated when the vehi-
cle’s speed is between approxima-
tely 30 km/h (19 mph) and 140 km/h
(87 mph).
This function uses sensors 1 installed
in the front and rear bumper of both
sides.

Activation/deactivation
On the multifunction screen 2, select
the “Vehicle” menu, “Driving assis-
tance”, and “Blind spot alert”, and then
choose “ON” or “OFF”.

Special feature
Make sure that the sensors are not obs-
cured (by dirt, mud, snow, etc.).
If a sensor is obscured, the message
“Blind spot clean sensor” will appear on
the instrument panel. If this happens,
please clean the sensors.
You can access the “Driving assis-
tance” menu directly by pressing the

Operating faults
If the system detects a fault, the mes-
sage “Check blind spot alert” is dis-
played on the instrument panel. Consult
an authorised dealer.
Note: When the engine is started, the
indicator light 4 (display B) flashes
three times. It is normal.
– The system’s detection
range operates according
to a standard lane width. If
you are driving in wide traf-
fic lanes, the system might not
be able to detect a vehicle in the
blind spot.
– The system might be disrupted momentarily if it is exposed to
strong electromagnetic waves
(as beneath high-tension power
lines) or to very poor weather
conditions (heavy rain, snow,
etc.). Remain aware of driving
conditions.
There is a risk of accidents.
BLIND SPOT WARNING (3/3)
Because sensors have
been installed in the bum-
pers, any work (repairs, re-
placements, touching up of
paintwork) must be carried out by a
qualified professional.

This function is an addi-
tional aid which indicates
other vehicles in the blind
spot area.
It can never in any case be a subs-
titute for care nor for the driver’s
responsibility while in charge of his
vehicle.
The driver should always look out
for sudden hazards during driving:
make sure while manoeuvring that
there are no moving or movable ob-
jects (such as a child, an animal, a
pushchair or a bicycle) or small or
narrow obstacles (such as a boulder
or a post) in the blind spot area.

SAFE DISTANCE ALERT (1/2)
Activating/deactivating the
function
From the multifunction screen 2, select
menu “Vehicle”, “Driving assistance”,
“Distance warning” then choose “ON”
or “OFF”.
1
Using the sensor 1 , this function noti-
fies the driver about the time interval
separating them from the vehicle in
front, so they can respect a safe dis-
tance between the two vehicles.
Note: make sure that the sensor 1 is
not obscured (by dirt, mud, snow, etc.).
The function is activated when the ve-
hicle speed is between about 20 and
125 mph (30 and 200 km/h).
When the engine is started, the func-
tion maintains the same status that was
active when the engine was last stop-
ped.
You can access menu “Driving as-
sistance” directly from button 3

This function is an additio-
nal driving aid. However,
this function is not under
any circumstances in-
tended to replace the due care and
attention of the driver, who should at
all times be in control of the vehicle.

SAFE DISTANCE ALERT (2/2)
The measurement is dis-
played for information only:
the system performs no
action on the vehicle.
This function is not designed for use
in urban conditions or for a dynamic
driving style (sudden cornering, ac-
celeration, braking, etc.), but rather
for stable driving conditions.
The function does not interact with
the braking system.
The sensor area should be kept
clean and free of any modifications
in order to ensure the proper opera-
tion of the system.
Any servicing on the bumper (re-
placement, repair, paint retouching,
etc.) should be undertaken by a
qualified professional.
– C (orange): the time interval falls
between around 1 and 2 seconds (in-
sufficient distance between the two
vehicles);
– D (red): the time interval is less than
or equal to around one second (very
insufficient distance between the two
vehicles).
If the interval between the two vehicles
is less than around 0.5 seconds, war-
ning light 4 will flash on the instrument
panel. Under certain conditions, the
time interval may not be displayed:
– while cornering;
– when changing lane;
– if the vehicle in front is sufficiently far or outside the range of the sensor.
This function is essential if adaptive
cruise control is activated.
On equipped vehicles, some infor-
mation is given on the head-up dis-
play.

Operation
Upon activating the function, indicator 4
notifies the driver of the distance sepa-
rating them from the vehicle in front.
– A (grey): function not operational;
– A (green): no vehicle detected;
– B (green): the time interval is greater
than or equal to around two seconds
(distance between the two vehicles
adapted to your speed);

ADAPTIVE CRUISE CONTROL (1/7)
When traffic conditions permit (large
free-flowing road or motorway), the
adaptive cruise control gives you the
option of maintaining a chosen speed,
known as cruise control, adjusta-
ble from 30 mph to 85 mph (50 and
140 km/h), while keeping a following
distance from the vehicle in front in the
same lane.
The sensor has a range of 120 metres.
Note: The driver should take into ac-
count the maximum speed limit in their
location.
Note: The adaptive cruise control can
brake the vehicle up to a third of the
braking capacity. Depending on the
situation, the driver may need to brake
harder.
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).
The adaptive cruise control should
not be used in heavy traffic, on
winding or slippery roads (black ice,
aquaplaning, gravel) and during bad
weather (fog, rain, side winds etc.).
There is a risk of accidents.
Sensor location
Make sure that the sensor 1 is not ob-
scured (by dirt, mud, snow, etc.).
