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
act
-
ing
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
automati
-
cally
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
instru
-
ment
panel.

that
the

F
Press
this

located
near
the
steering
wheel.
If
the
indicator
lamp
in
the
button
comes

this
indicates
that
these
systems
are
deactivated.
Depending
on
version,
your
vehicle
has
a
system
to
help
driving
on
snow:
intel
-
ligent traction control.
This
system
detects
situations
of
diffi
-
cult
surface
adhesion
that
could
make
it
difficult
to
move
of
f
or
make
progress
on
deep
fresh
snow
or
compacted
snow.
In these situations, the intelligent trac-
tion control
limits
the
amount
of
wheel
slip
to
provide
the
best
traction
and
trajectory
control
for
your
vehicle.
The
use
of
snow
tyres
is
strongly recommended
on
surfaces
of
fer-
ing
low
levels
of
adhesion. It
is
recommended
that
the
systems
be
reactivated
as soon as possible.

The driver must ensure that passen -
gers use the seat belts correctly and
that
they
are
all
restrained
securely
before
setting off.
Wherever
you
are
seated
in
the
ve
-
hicle, always fasten your seat belt,
even
for short journeys.
Do
not
interchange
the
seat
belt
buckles
as
they

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

are
fitted
with
an
auto

locking
device
which
comes
into operation in the event of a collision,
emergency
braking
or
if
the

can
release
the
device by
pulling
the
strap
firmly
and
then
re

leasing
it so that it reels in slightly.In
order to be ef fective, 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
accordance
with
current
safety
regulations,
for
all
repairs
on
your
vehicle's
seat
belts,
go
to
a
qualified
workshop
with
the
skills
and
equip
-
ment
needed,
which
a
CITROËN
dealer
is able to provide.
Have
your
seat
belts
checked
regu
-
larly
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.Recommendations for children
Use
a
suitable
child
seat
if
the
pas
-
senger
is
less
than
12
years
old
or
shorter
than one and a half metres.
Never
use
the
same
seat
belt
to
se
-
cure
more than one person.
Never
allow
a
child
to
travel
on
your
lap.
For
more
information,
refer
to
the
"Child
seats" section.
In the event of an impact
Depending on the nature and se-
riousness of the impact, the pre-
tensioning
device
may
be
deployed
before
and
independently
of
the
airbags.
Deployment
of
the
preten
-
sioners
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
neces
-
sary
replaced,
by
a
CITROËN
dealer
or

AIRBAGS
System designed to contribute towards improving
the safety of the occupants
(with
the
exception
of
the
rear
centre
passenger)
in
the
event
of
violent
colli-
sions.
The

supplement
the
ac
-
tion
of
the
force-limiting
seat
belts
(with
the
exception
of

If

Impact detection zones
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
incor
-
porated
in the system.
This
smoke
is
not
harmful,
but
sensitive
individuals
may
experi
-
ence
slight irritation.
The
noise
of
detonation
related
to
the
deployment
of
one
or
more
airbags
may
result
in
a
slight
loss
of
hearing
for
a
short
time.
Front airbags
System which protects the driver and front
passenger in the event of a seri -
ous
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
passen
-
ger'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
deactivat
-
ed,
in
the
event
of
a
serious
front
impact to
all

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
tho
-
rax
and
head
of
the
front
occupant
of
the vehicle
and
the
steering
wheel,
driver's side,
and
the

passenger's side
to cushion their forward movement.
This
equipment
will
only
deploy
once.
If
a
second
impact
occurs
(during
the
same
or
a
subse
-
quent
accident),
the
airbag
will
not
be
deployed
again.

For the airbags to be fully
effective, observe the
following safety rules:
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...).
This
could
hamper
the
operation
of
the
air
-
bags
or injure the occupants.
After
an
accident
or
if
the
ve
-
hicle
has
been
stolen
or
broken
into,
have
the
airbag
systems
checked.
All
work
on
the
airbag
system
must be
carried
out
by
a
CITROËN
deal
-
er
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
air

bag
is
deployed
cannot
be
ruled
out.
The

then
deflates
within
the

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.
Lateral airbags
Use
only
approved
covers
on
the
seats,
compatible
with
the
deployment
the
lat

eral
airbags.
For
information
on
the
range
of
seat
covers
suitable
for
your

you
can contact a CITROËN dealer.
Refer
to the "Accessories" section.
Do
not
fix
or
attach
anything
to
the

backs
(clothing...).
This
could
cause
injury
to the chest or arms if the lateral airbag is deployed.
Do

A FEW DRIVING RECOMMENDATIONS
Observe the driving regulations at all times
and remain vigilant whatever the
traffic
conditions.
Pay
close
attention
to
the
traffic
and
keep
your
hands
on
the
wheel
so
that
you
are
ready
to
react
at
any
time
to
any
eventuality.
On
a
long
journey
,
a
break
every
two hours
is strongly recommended.
In
difficult
weather
,
drive
smoothly
,
an

the
distance from other vehicles.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause seri -

as
well
as
to
the
electrical
systems
of
your
vehicle.
Important!
Never drive with the parking brake
applied - Risk of overheat -
ing
and
damage
to
the
braking
system!
Do
not
park
or
run
the
engine when
stationary in areas where
inflammable substances and ma -terials (dry grass, dead leaves...) might
come into contact with the hot
exhaust
system
-
Risk
of
fire!
n
ever leave a vehicle unsuper-
vised
with
the
engine
running.
If
you have to leave your vehicle

apply
the
parking
brake
and
put
the
gearbox
into
neutral
or
posi

tion
N
or P,
depending

obliged
to
