Braking assistance systems
Group of supplementary systems which help you to obtain optimum braking in complete
s
afety 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,
i
n particular on poor or slippery sur faces.
Activation
The anti-lock braking system comes into operation automatically when there is a risk of
w
heel lock.
Normal
operation of the ABS may make itself
f
elt by slight vibration of the brake pedal.
When
braking in an emergency, press
v
ery firmly without releasing the
p
ressure.
Operating fault
If this warning lamp comes on, together with the STOP and ABS
warning
lamps, accompanied by an
a
udible
signal and a message in the screen, it
i
ndicates
a malfunction of the electronic brake
f
orce distribution which could result in loss of
control
of
the vehicle when braking.
You must stop as soon as it is safe to do so.
When
replacing wheels (tyres and
r
ims), ensure that they conform to the
ma
nufacturer's
r
ecommendations.
If
this warning lamp comes on,
a
ccompanied by an audible signal
a
nd a message in the screen, it
i
ndicates
a malfunction of the anti-lock braking
s
ystem
which could result in loss of control of
t
he
vehicle when braking.
In either case, contact a CITR
oË
N dealer or a
qualified
w
orkshop.

Emergency braking assistance
System which, in an emergency, enables you to obtain the optimum braking pressure more
q
uickly, 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
e
fficiency.
When
braking in an emergency, press
f
irmly without releasing the pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and electronic stability
programme (ESP)
The anti-slip regulation (also known as Traction Control) optimises traction to prevent skidding
o
f the wheels, by acting on the brakes of the
d
riving wheels and on the engine.
The
electronic stability programme acts on the
b
rake of one or more wheels and on the engine
t
o keep the vehicle on the trajectory required
b
y the driver, within the limits of the laws of
p
hysics.Activation
These systems are activated automatically each time the vehicle is started.
They
come into operation in the event of a grip
o
r
t
rajectory
pro
blem.
This
is indicated by flashing of this
w
arning lamp in the instrument panel.
Safety
deactivation
In exceptional conditions (starting a vehicle which is bogged down, stuck in snow, on soft
g
round...), it may be advisable to deactivate the
A
SR and ESP systems, so that the wheels can
m
ove freely and regain grip.
F

the
left below the steering wheel.

Reactivation
These systems are reactivated automatically each time the ignition is switched back on or
f
rom 30 mph (50 km/h) except 1.6 litre
(THP 150, THP 155 and THP 160) and
R ACING
petrol engines.

Operating fault
The ESP/ASR systems offer exceptional s afety i n n ormal d riving, b ut
t
his should not encourage the driver to
t
ake extra risks or drive at high speed.
The
correct functioning of these
s
ystems depends on observation of the
ma
nufacturer's

Operating limits
The system only detects vehicles that are stationary or moving in the same direction as
y
our vehicle.
It
does not detect small vehicles
(
bicycles, motorcycles), pedestrians or
a
nimals, nor non-reflective stationary
ob
jects. In difficult weather conditions (very
heavy
rain, snow, fog, hail...), braking
d
istances increase, which can reduce
the
ability of the system to avoid a
c
ollision.
The
driver must therefore remain
par
ticularly
v
igilant.
Never
leave accumulations of snow or
a
ny object projecting above the bonnet
o
r in front of the roof: this might fall into
t
he field of vision of the sensor and
generate
a detection.
The
system is not triggered or is interrupted if t
he d river:
-
a
ccelerates strongly
-
o
r turns the steering wheel suddenly
(
avoiding
m
anoeuvre).
Safety
Front airbags
System which protects the driver and front passenger in the event of a serious front impact
i
n order to limit the risk of injury to the head and
c
hest.
The
driver's airbag is fitted in the centre of the
s
teering wheel; the front passenger's airbag is
f
itted in the dashboard above the glove box.deployment
The airbags are deployed, except the passenger's front airbag if it is deactivated,
i
n the event of a serious front impact applied
t
o all or part of the front impact zone A, in
the
longitudinal centreline of the vehicle on a
h
orizontal plane and directed from the front to
t
he rear of the vehicle.
The
front airbag inflates between the head-
thorax
of the front occupant of the vehicle
an
d the dashboard to cushion their forward
movement.
For the airbags to be fully effective, observe the following safety rules:Front airbags
Do not drive holding the steering wheel by its spokes or resting your hands on the centre
p
art of the wheel.
Passengers
must not place their feet on the
das
hboard.
Do
not smoke as deployment of the airbags
c
an cause burns or the risk of injury from a
c
igarette or pipe.
Never
remove or pierce the steering wheel or
h
it it violently.
Do
not fit or attach anything to the steering
w
heel or dashboard, this could cause injuries
w
ith deployment of the airbags.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment the lateral
a
irbags. For information on the range of seat
c
overs suitable for your vehicle, you can
contact
a CITROËN dealer.
Refer
to the "Accessories" section.
Do
not fix or attach anything to the seat
b
acks (clothing...). This could cause injury
t
o the chest or arms if the lateral airbag is
d
eployed.
Do not sit with the upper part of the body any
nearer
to the door than necessary.
curtain airbags
Do not fix or attach anything to the roof. This could cause injury to the head if the
c
urtain airbag is deployed.
If
fitted on your vehicle, do not remove the
g
rab handles installed on the roof, they play
a
part in securing the curtain airbags.
Sit
in
a
normal
upright
position.
Wear
a
correctly
adjusted
seat
belt.
Do
n
ot

eave
a
nything

the
airbags
(a
child,
pet,
object...).
This

hamper
the
operation
of
the
airbags
or
i
njure
the
occupants.
af
ter an accident or if the vehicle has been
stolen
or
broken
into,
have
the
airbag
s
ystems
checked.
All
work
on
the
airbag
system
must
be
c
arried out by a CITR
oË
N dealer or a
qualified
w
orkshop.
Even
if
all
of
the
precautions
mentioned
a
re
observed,
a
risk
of
injury
or
of
minor
b
urns
to
the
head,

or
arms
when
an
a
irbag
is
deployed
cannot
be
ruled
out.
The

then
deflates
within
the
