Cornering lighting
With dipped or main beams, this function

to illuminate the inside of a bend, when the
vehicle speed is below 25 mph (40 km/h)

Braking assistance systems
Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-
a
nti-lock braking system (ABS),
-

e
lectronic brake force distribution (EBFD),
-

e
mergency braking assistance (EBA).Anti-lock braking system and electronic brake force distribution
Linked systems which improve the stability and manoeuvrability of your vehicle when braking, in
particular on poor or slippery sur faces.
Activation
The anti-lock braking system comes into
operation automatically when there is a risk of
wheel lock.
Normal operation of the ABS may make itself
felt by slight vibration of the brake pedal. When braking in an emergency, press
very firmly without releasing the
pressure.
Operating fault
If this warning lamp comes on,
together with the STOP and ABS
warning lamps, accompanied by an

rims), ensure that they conform to the
manufacturer's recommendations. If this warning lamp comes on,

155
Emergency braking assistance
System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.
Activation
It is triggered by the speed at which the brake
pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase in
braking efficiency.When braking in an emergency, press
firmly without releasing the pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability control
(DSC)
The anti-slip regulation (also known as traction
control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability control acts on the brake
of one or more wheels and on the engine to
keep the vehicle on the trajectory required by
the driver, within the limits of the laws of physics.
Activation
These systems are activated automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem. This is indicated by flashing of this
warning lamp in the instrument panel.
Intelligent traction control
system ("Snow motion")
Depending on version, your vehicle has a
system to help driving on snow: intelligent
traction control .
This system detects situations of difficult
sur face grip that could make it difficult to move
off or make progress on deep fresh snow or
compacted snow.
In these situations, the intelligent traction
control limits the amount of wheel spin to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of adhesion.

Safety

156
In extremely severe conditions (deep snow,
mud, ...), if you are unable to move off, it may
be useful to temporarily deactivate these
systems so that the wheels can spin freely and
allow the vehicle to move.
If the indicator lamp in the button comes on, this
indicates that these systems are deactivated.
Reactivation
These systems are reactivated automatically
each time the ignition is switched back on or
from 30 mph (50 km/h).
F
P
ress this button again to reactivate them
manually.
Operating fault
The trajectory control systems offer
increased safety in normal driving, but
this should not encourage the driver to
take extra risks or drive at high speed.
The correct functioning of these
systems is assured provided that
manufacturer's recommendations are
observed on:
-

After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
The illumination of the indicator
lamps in the instrument panel and
in this button, accompanied by an
audible signal and a message in the
screen, indicates a fault with these
systems.
It is recommended that the systems be
reactivated as soon as possible. Have it checked by a CITROËN dealer or a
qualified workshop.
Deactivation

wheel.

Front airbags
System which protects the driver and front
passenger in the event of a serious front impact
in order to limit the risk of injury to the head and
thorax.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger's airbag is
fitted in the dashboard above the glove box.
Deployment
The airbags are deployed, except the
passenger's front airbag if it is deactivated, in
the event of a serious front impact to all or part
of the front impact zone A, in the longitudinal
centreline of the vehicle on a horizontal plane
and directed from the front to the rear of the
vehicle.
The front airbag inflates between the thorax
and head of the front occupant of the vehicle
and the steering wheel, driver's side, and the
dashboard, passenger's side to cushion their
for ward movement.
