Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
- anti-lock braking system (ABS),
- electronic brake force distribution (EBFD).

Braking assistance systems

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 surfaces.

Activation

The anti-lock braking system is active if the
vehicle speed is higher than 6 mph (10 km/h).
It is deactivated when the vehicle speed falls
below 3 mph (5 km/h).
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.

Operating fault

When the vehicle is stationary

If this warning lamp comes on, accompanied by
the indication on the instrument panel screen, it
indicates a malfunction of the anti-lock braking
system which could result in a loss of control of
the vehicle when braking.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or a qualified workshop as
soon as possible.

When braking in an emergency, press
very firmly without releasing the
pressure.

The warning lamp comes on for a few
seconds when the ignition is switched on
(ON position). If it does not switch off or
does not come on, contact a CITROËN
dealer or a qualified workshop.

If this warning lamp comes
on continuously it indicates a
malfunction of the anti-lock braking

system which could result in a loss of
control of the vehicle on braking.

The two warning lamps comes on at the
same time and the two warnings are
displayed alternately in the instrument
panel screen.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.

The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or qualified workshop as
soon as possible.

If these two warning lamps come on, linked
with the warnings on the instrument panel
screen, they indicate a malfunction of the
electronic brake force distribution which could
result in a loss of control of the vehicle on
braking.
You must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop.

Associated systems which contribute to the directional stability of the vehicle within the limits of the laws of physics:
-

traction control (TCl),

- active stability control (ASC).

Traction control and active stability control

Traction control optimises traction to prevent
wheel spin, by acting on the brakes of the
driving wheels and on the engine.
Active 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.

Activation

These systems are activated automatically
each time the vehicle is started.

The illumination of this warning lamp
in the instrument panel indicates
that the ASC and TCL systems are
deactivated.

Deactivation

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, ...), it may be advisable to deactivate
the ASC system, so that the wheels can move
freely and regain grip.

This is indicated by the flashing of
this symbol on the instrument panel
screen.

Trajectory control systems

F

Press this button, located to the left of the

steering wheel, until the symbol appears in
the instrument panel screen.

Operation

They operate when the vehicle speed is higher
than 9 mph (15 km/h).
They come into operation in the event of a grip
or trajectory problem.

Reactivation

Operating fault

The illumination of one of these warning lamps
accompanied by a message in the instrument panel
screen indicates a malfunction of these systems.
Contact a CITROËN dealer or a qualified
workshop to have the ASC/TCL systems
checked.

The ASC/TCL systems offer exceptional
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 depends on observation of the
manufacturer's recommendations on:
- wheels (tyres and rims),
- braking components,
- electronic components,
- assembly and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.

F

Advice

The driver must ensure that passengers use
the seat belts correctly and that they are all
fastened before setting off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
Do not interchange the seat belt buckles as
they will not fulfill their role fully.
The seat belts are fitted with an inertia reel
permitting automatic adjustment of the
length of the strap to your size. The seat belt
is stowed automatically when not in use.
Before and after use, ensure that the seat
belt is reeled in correctly.
The lower part of the strap must be
positioned as low as possible on the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
The inertia reels are fitted with an automatic
locking device which comes into operation in
the event of a collision, emergency braking
or if the vehicle rolls over. You can release
the device by pulling the strap firmly and
then releasing it so that it reels in slightly.

Recommendations for children

Use a suitable child seat if the passenger is
less than 12 years old or shorter than one
and a half metres.
Never use the same seat belt to secure more
than one person.
Never allow a child to travel on your lap.
For more information on Child seats, refer
to the corresponding section.

In order to be effective, a seat belt must:
- be tightened as close to the body as

possible,

- be pulled in front of you with a smooth

movement, checking that it does not
twist,

- be used to restrain only one person,
- not bear any trace of cuts or fraying,
- not be converted or modified to avoid

affecting its performance.

In the event of an impact

Depending on the nature and
seriousness of the impact, the
pretensioning device may be deployed
before and independently of the airbags.
Deployment of the pretensioners is
accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
In all cases, the airbag warning lamp comes on.
Following an impact, have the seat belts
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.

In accordance with current safety
regulations, for all repairs on your vehicle's
seat belts, go to a qualified workshop with
the skills and equipment needed, which a
CITROËN dealer is able to provide.
Have your seat belts checked regularly by
a CITROËN dealer or a qualified workshop,
particularly if the straps show signs of
damage.
Clean the seat belt straps with soapy
water or a textile cleaning product, sold by
CITROËN dealers.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.

Airbags

General information

System designed to contribute towards

improving the safety of the occupants (with

the exception of the rear centre passenger)

in the event of violent collisions. The airbags

supplement the action of the seat belts fitted

with force limiters (all except the centre rear

passenger belt).

If a collision occurs, the electronic detectors

record and analyse the front and side impacts

sustained in the impact detection zones:

- in the case of a serious impact, the airbags

are deployed instantly and contribute

towards better protection of the occupants

of the vehicle (with the exception of the

rear centre passenger); immediately after

the impact, the airbags deflate rapidly so

that they do not hinder visibility or the exit
of the occupants,

- in the case of a minor or rear impact or in

certain roll-over conditions, the airbags

may not be deployed; the seat belt

alone contributes towards ensuring your

protection in these situations.

The airbags do not operate when the
ignition is switched off.
This equipment will only deploy once.
If a second impact occurs (during the
same or a subsequent accident), the
airbag will not be deployed again.

Deployment of one or more of the
airbags is accompanied by a slight
emission of smoke and a noise, due
to the activation of the pyrotechnic
cartridge incorporated in the system.
This smoke is not harmful, but sensitive
individuals may experience slight
irritation.
The noise of detonation associated with
the deployment of one or more airbags
may result in a slight loss of hearing for
a short time.

Impact detection zones

A.

Front impact zone.

B.

Side impact zone.

Front airbags

Deployment

The airbags are deployed, except the
passenger's front airbag if it is deactivated,
in the event of a serious front impact applied
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 front
occupant of the vehicle and the dashboard to
cushion their forward movement.

System which contributes toward improving
protection for the head and chest of the driver
and front passenger in the event of a front
impact.
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.

centre console panel, when the
ignition is on and until the airbag is

reactivated.

To ensure the safety of your child, the
passenger's airbag must be deactivated
when you install a "rearward facing"
child seat on the front passenger seat.
Otherwise, the child would risk being
seriously injured or killed if the airbag
were triggered.

If the airbag warning lamp and the
display come on continuously, do not
install a "rearward facing" child seat on
the front passenger seat.
Contact a CITROËN dealer or a
qualified workshop without delay.

Reactivation

When you remove the "rearward facing" child
seat, turn switch A to the "ON" position to
reactivate the airbag and so ensure the safety
of your front passenger in the event of an
impact.
The associated warning lamp goes off.

Safety

C4-Aircross_en_Chap06_securite_ed01-2016

For the airbags to be fully
effective, observe the safety
recommendations below:

Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the
occupants and the airbags (a child, pet,
object...), nor fix or attach anything close to
the inflation trajectory of the airbags; this
could cause injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly
around the airbags.
After an accident or if the vehicle has been
stolen or broken into, have the airbag
systems checked.
All work on the airbag system must be
carried out by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are observed, a risk of injury or of minor
burns to the head, chest or arms when an
airbag is deployed cannot be ruled out. The
bag inflates almost instantly (within a few
milliseconds) then deflates within the same
time discharging the hot gas via openings
provided for this purpose.

Knee airbag*

Do not sit with your knees any nearer to the
steering wheel than necessary.

Front airbags

Do not drive holding the steering wheel by its
spokes or resting your hands on the centre
part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fit or attach anything to the steering
wheel or dashboard, this could cause
injuries with deployment of the airbags.

Advice

Lateral airbags

Use only approved covers on the seats,
compatible with the deployment the lateral
airbags. For information on the range of seat
covers suitable for your vehicle, you can
contact a CITROËN dealer.
Do not fix or attach anything to the seat
backs (clothing...). This could cause injury
to the chest or arms if the lateral airbag is
deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.

* Depending on country of sale.

Avoid attaching a heavy object to the key as
it could become a dangerous projectile if the
airbag were deployed.

Curtain airbags

Do not fix or attach anything to the roof. This
could cause injury to the head if the curtain
airbag is deployed.
If fitted on your vehicle, do not remove the
grab handles installed on the roof, they play
a part in securing the curtain airbags.
