DRIVER CORRECTION DEVICES AND AIDS (4/12)
Emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
Operating principle
The system is for detecting an emer-
gency braking situation. In this case,
the braking assistance immediately de-
velops maximum power and may trig-
ger ABS regulation.
ABS braking is maintained as long as
the brake pedal is applied.
Hazard warning lights switching on
Depending on the vehicle, these may
light up in the event of sudden decele-
ration. Braking anticipation
Depending on the vehicle, when you
rapidly release the accelerator, the
system anticipates the braking ma-
noeuvre in order to reduce stopping
distances.
Special cases
When using the cruise control:
– if you use the accelerator, when you
release it, the system may be trigge-
red;
– if you do not use the accelerator, the system will not be triggered.
Operating faults
When the system detects an operat-
ing fault the message “Check brak-
ing system” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.

Advanced traction control
If fitted on the vehicle, grip control
makes it easier to control the vehicle on
low grip surfaces (soft ground, etc.).
Tyres
When they need to be re-
placed, only tyres of the
same make, size, type and
profile should be used.
Tyres fitted to the vehicle should
either be identical to those fitted
originally or conform to those re-
commended by your approved
dealer.
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle beha-
viour to be adapted to suit the dri-
ving 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 responsibi-
lity of the driver when manoeuvring
the vehicle (the driver must always
be ready for sudden incidents which
may occur when driving).
Activating or deactivating the
system
From the multifunction screen, select
menu “Vehicle”, “Driving assistance”,
“Traction control” then select the mode:
« Auto »
The “Auto Advanced Traction Control”
message is shown on the instrument
panel for approximately 15 seconds.
This position enables optimal usage
under normal driving conditions (dry-
ness, humidity, light snow, etc.).
« Expert »
This position enables optimal usage on
soft ground (mud, sand, dead leaves,
etc.). “Expert” mode uses traction con-
trol functions.
The system automatically switches
to «Auto" mode at speeds above ap-
proximately 24.8 mph (40 km/h) and
the message "Auto Advanced Traction
Control» is displayed on the instrument
panel for approximately 15 seconds. Note: The system’s default mode is
“Auto” mode.

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 90 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.

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.
Activating or deactivating the
system
From the multifunction screen 3, select
menu “Vehicle”, “Driving assistance”,
“Active braking” then choose “ON” or
“OFF”.
Warning light
is displayed on the
instrument panel when the system is
deactivated.
This system is reactivated each time
the ignition is switched on.
DRIVER CORRECTION DEVICES AND AIDS (7/12)
You can access the “Driving as-
sistance” menu directly from the
button 4
\b.
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 experien- cing 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.3

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 work in the area where the radar is located (repairs, replacements,\
touching up of paintwork) must be carried out by a qualified professional.
– 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 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 i-
dance manoeuvre.
If the driver notices any unusual behaviour in the system, please consul\
t an authorised dealer.

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 plug-
ged in but no trailer is atta-
ched (bicycle carrier, lug-
gage carrier with lighting,
etc.), the function may act under
certain rutted road conditions.
Risk of vehicle deceleration.
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.

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 rol-
ling backwards in all situa-
tions (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.
