DRIVER CORRECTION DEVICES AND AIDS (7/10)
Active emergency braking
This function is an additional driving aid. However, this function is not
under any circumstances intended to replace the due care and attention
of the driver, who should at all times be in control of the vehicle.
System servicing/repairs
– In the event of an impact, the sensor alignment may become changed, and \
its operation will consequently be affected. Deactivate the function, then consult
an authorised dealer.
– Any work in the area where the radar is located (repairs, replacements,\
touch- ing up of paintwork) must be carried out by a qualified professional.
Only an authorised dealer is qualified to service the system.
In the event of system disturbance
Some conditions can disturb or damage the operation of the system, such \
as:
– a complex environment (metal bridge, etc.);
– poor weather conditions (snow, hail, black ice, etc.).
Risk of inadvertent braking.
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 experienc- ing difficulties (for example: sensor
obscured by dirt, mud, snow etc.);
in this case, park the vehicle and
switch off the engine. Clean the de-
tection 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.

DRIVER CORRECTION DEVICES AND AIDS (10/10)
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 3). 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.
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.

LANE DEPARTURE WARNING (1/3)
This function is a driving aid in the event of the accidental crossing o\
f
a continuous or broken line in the road. However, the function is not in-
tended to replace the driver. The function can be disrupted under certain
conditions, including:
– poor visibility (rain, snow, fog, dirty windscreen, glare of the sun, partially ob- scured road lines, etc.);
– roads with tight bends;
– closely following a vehicle in the same lane;
– worn road markings, difficult to distinguish or spaced very widely apart;
– narrow roads;
– ...
In this case, the line visibility indicators remain uncoloured on the in\
strument
panel to indicate that the function will not operate (lines not detecte\
d).
Under no circumstances should this function replace the driver’s care or respon-
sibility whilst performing manoeuvres.
This system notifies the driver when
they accidentally cross a continuous or
broken line.
This function uses a camera attached
to the windscreen, behind the rear-view
mirror.

2.41
LANE DEPARTURE WARNING (2/3)
The function is set to notify the
driver if:
– the vehicle speed is greater than ap-proximately 45 mph (70 km/h);
and
– lines are detected and the visibility indicators 4 are, depending on the
vehicle, green or white.
The function triggers an alert if a
line is crossed without the direction in-
dicators being activated. The function
alerts the driver by means of a beep
and, depending on the vehicle, the vis-
ibility indicators 4 change to red, or the
graphic 5 is displayed on the instrument
panel.Activation/deactivation

BLIND SPOT WARNING (1/4)
This system alerts the driver to other
vehicles in the detection zone A.
The system is activated when the ve-

Special featureMake sure that the sensors are not ob-
scured (by dirt, mud, snow, etc.).
If a sensor is obscured, the message
“Blind spotclean sensor” will appear on
the instrument panel. Clean the sen-
sors.
AThis 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.

BLIND SPOT WARNING (3/4)
Operation
This function will indicate:
– when the vehicle speed is between approximately 30 km/h (19 mph) and
140 km/h (87 mph);
– when another vehicle is in the blind spot area and travelling in the same
direction as your vehicle.
If another vehicle is being overtaken,
the indicator 6 will be activated only if
that vehicle remains in the blind spot for
more than one second.
Indicator 6
An indicator light 6 is located on each
door mirror 7.
Note: clean the door mirrors 7 regu-
larly so that the indicator lights 6 can be
seen properly.
Display B
The function is activated and has not
detected any vehicles.
Display C
First warning: the indicator 6 means
that a vehicle has been detected in the
blind spot.
Display D
When the direction indicator is acti-
vated, the indicator light 6 flashes when
a vehicle is detected in the blind spot on
the side towards which you are about to
steer. If you cancel the direction indica-
tor, the function will return to the initial
warning (display C).

Note: The system’s detection range
operates according to a standard
lane width. If you are driving in
narrow traffic lanes, it may detect
vehicles in other lanes.

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 6, 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 (4/4)
Because sensors have
been installed in the bump-
ers, any work (repairs, re-
placements, touching up of
paintwork) must be carried out by a
qualified professional.

Activating/deactivating the
function
From the multifunction screen 2, select
menu “Vehicle”, “Driving assistance”,
“Distance warning” then choose “ON”
or “OFF”.

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
