DRIVER CORRECTION DEVICES AND AIDS (8/12)
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 servicing on the bumper (replacement, repair, paint retouching, etc.) should be undertaken by a qualified professio\
nal.
– Fitting accessories which may block the radar is prohibited (bull-bars,\
etc.).
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.

DRIVER CORRECTION DEVICES AND AIDS (9/12)
Active emergency braking
Limitation of the system operation
– The system will only respond to vehicles which are moving or which have \
been sensed as moving.
– A vehicle travelling in the opposite direction will not trigger any alert\
or any action on the system operation.
– The sensor area should be kept clean and free of any modifications in or\
der 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.
Deactivating the function
The function should be deactivated if:
– the brake lights are not functioning;
– the bumper has suffered an impact or damage;
– the vehicle is being towed (breakdowns).
Halting the function
You can halt the automatic braking function at any time by tapping the ac\
celerator pedal or by turning the steering wheel in a
avoidance manoeuvre.
If the driver notices any unusual behaviour in the system, please consul\
t an authorised dealer.

2.35
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.

DRIVER CORRECTION DEVICES AND AIDS (11/12)
Hill start assistance
This function assists the driver when
starting on hills. It prevents the vehicle
from rolling backwards by automatically
applying the brakes when the driver lifts
his/her foot off the brake pedal to de-
press 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.

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.

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 obs- cured 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 res-
ponsibility 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.
On equipped vehicles, some infor-
mation is given on the head-up dis-
play.

LANE DEPARTURE WARNING (2/3)Conditions for non-activation
of alerts
– Indicators activated or having been activated less than approximately
four seconds prior to departing from
the lane;
– Very fast lane departure;
– Driving continuously on a line;
– On bends, the function allows for slightly cutting the bend;
– ...
Activation/deactivation
From the multifunction screen 1: select
“Vehicle”, “Driving assistance”, “Lane
departure warning” then choose “ON”
or “OFF”.

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 3 are green.
The function triggers an alert if a line
is crossed without the direction indica-
tors being activated. The function alerts
the driver through a beep and the indi-
cator the line crossed switches to red
on the instrument panel.
You can access menu “Driving as-
sistance” directly from button 2
