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 of the wheels, by act-
ing on the brakes of the driving wheels
and on the engine.
The electronic stability programme 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 fl ashing of
this warning lamp in the instru-
ment panel.

(Intelligent Traction Control)

Your vehicle has a system to help driving
on snow: Intelligent Traction Control.
This automatic system continuously
checks for situations of diffi cult surface
adhesion that could make it diffi cult to
move off or make progress on deep
fresh snow or compacted snow.
In these situations, Intelligent Traction
Control
takes over from the ASR
sys-
tem, limiting the amount of wheel slip to
provide the best traction and trajectory
control, even without snow tyres and
with or without chains.
In extremely severe conditions (snow
on top of ice, sand, deep mud…), it can
be useful to deactivate the ESP/ASR

systems to allow a degree of wheel spin
and so recover grip.

Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), it may be ad-
visable to deactivate the ASR and ESP
systems, so that the wheels can move
freely and regain grip.


)
Press the "ESP OFF"
button, located
on the left below the steering wheel.

If this warning lamp comes on
in the instrument panel and
the indicator lamp in the button
comes on, this indicates that
the ASR and ESP systems are
deactivated.

SAFETY
134
The ESP/ASR systems offer
exceptional safety in normal
driving, but this should not en-
courage the driver to take extra
risks or drive at high speed.
The correct functioning of these
systems is assured provided
that manufacturer's recommen-
dations are observed on:


- wheels (tyres and rims),

- braking components,

- electronic components,

- assembly and repair proce-
dures.
After an impact, have these sys-
tems checked by a CITROËN
dealer or a qualifi ed workshop.

Reactivation
These systems are reactivated automat-
ically each time the ignition is switched
back on or from 30 mph (50 km/h).


)
Press the "ESP OFF"
button again
to reactivate them manually.


If this warning lamp comes on,
accompanied by an audible
signal and a message in the
screen, this indicates a fault
with these systems.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
Operating fault EMERGENCY OR ASSISTANCE CALL

This system allows you to make an
emergency or assistance call to the
emergency services or to the dedicated
CITROËN service.

SEAT BELTS

Front seat belts


The front seat belts are fi tted with a pre-
tensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side im-
pact. Depending on the severity of the
impact, the pretensioning system in-
stantly tightens the seat belts against
the body of the occupants.
The pretensioning seat belts are active
when the ignition is on.
The force limiter reduces the pressure
of the seat belt on the chest of the oc-
cupant, so improving their protection.











Fastening


)
Pull the strap, then insert the tongue
in the buckle.

)
Check that the seat belt is fastened
correctly by pulling the strap.


Unfastening


)

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 will not fulfi l their role
fully.
The seat belts are fi tted 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 fi tted with an au-
tomatic locking device which comes
into operation in the event of a colli-
sion, emergency braking or if the ve-
hicle rolls over. You can release the
device by pulling fi rmly on the strap
and releasing it so that it reels in
slightly. 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 modifi ed to
avoid affecting its performance.
In accordance with current safety
regulations, for all repairs on your ve-
hicle, go to a qualifi ed workshop with
the skills and equipment needed,
which a CITROËN dealer is able to
provide.
Have your seat belts checked regu-
larly by a CITROËN dealer or a
qualifi ed 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.

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 a qualifi ed workshop.
