ANTI-SLIP REGULATION (ASR) AND DYNAMIC STABILITY CONTROL (DSC)
These systems are linked and complement
the ABS.
The ASR system is very useful for
maintaining optimum drive and avoiding
losses of control of the vehicle on
acceleration.
The system optimises drive to prevent the
wheels skidding, by acting on the brakes of
the drive wheels and on the engine. It also
allows the directional stability of the vehicle
to be improved on acceleration. If there is a variation between the trajectory
followed by the vehicle and that required by
the driver, the DSC system automatically
acts on the engine and the brake of one
or more wheels, in order to put the vehicle
back on course.
Deactivation
In certain exceptional conditions (starting
the vehicle when stuck in mud or snow, or
on loose ground...), it could prove useful
to deactivate the ASR and DSC systems to
make the wheels spin and regain grip.
Operating fault
Good practice
The ASR/DSC systems offer increased
safety during normal driving, but should not
encourage the driver to take risks or to drive
at high speed.
The operation of these systems is assured
only if the recommendations of the
manufacturer regarding the wheels (tyres
and rims), the braking components, the
electronic components and fitting and repair
procedures are observed.
After an impact, have these systems
checked by a CITROËN dealer or a qualified
workshop.
Use the DSC to hold your course without
attempting to countersteer.
Operation
The warning lamp flashes when
operation of the ASR or DSC is
triggered.
They engage again:
- automatically above 30 mph (50 km/h),
- manually by pressing the button again. When a malfunction of the
systems occurs, the warning
lamp and the LED come on,
accompanied by an audible signal
and a message in the screen.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The warning lamp may also come on if the
tyres are under-inflated. Check the pressure
of each tyre.
- Press the button, located on the centre console.
- The LED comes on: the ASR and DSC systems no longer
operate.

"GRIP CONTROL"
On snow, mud and sand, this traction
system, associated with the Michelin ® Agilis
51 M+S all terrain tyres, provides a
compromise between safety, adhesion and
traction.
It allows progress to be made in most
conditions of low adhesion. The accelerator pedal must
be pressed sufficiently
so that the engine power
can be used to effectively
manage the various
parameters. Correct use
Your vehicle is designed principally to drive
on tarmac roads but it allows you to drive on
other less passable terrain occasionally.
However, particularly when your vehicle is
heavily laden, it does not permit off-road
activities such as:
- crossing and driving on ground which
could damage the underbody or tear off
components (fuel pipe, fuel cooler, ...),
particularly by obstacles or stones,
- driving on ground with steep gradients and poor grip,
- crossing a stream.

This DSC mode is calibrated for
a low level of skidding, based
on different conditions of grip
encountered on the road.
When the ignition is switched off, the system
returns automatically to DSC mode.
This DSC OFF mode is only
suitable for specific conditions
encountered when moving off or
at low speed.
Above 30 mph (50 km/h) the system returns
to DSC mode automatically. This snow mode allows the
vehicle to adapts its strategy
to the conditions of grip
encountered for each of the two
front wheels, on moving off.
When moving, the system optimises
wheelspin to provide the best acceleration
possible for the grip available.
This off-road mode (mud, wet
grass...) allows, when moving off,
considerable wheelspin on the
wheel with the least grip to favour
clearing of the mud and regain "grip". At the
same time, the wheel with the most grip is
controlled in such a way as to transmit as
much torque as possible.
When moving, the system optimises
wheelspin to meet the driver's requirements
as fully as possible. This sand mode allows a little
wheelspin on the two driving
wheels at the same time to allow
the vehicle to move forward and
reduces the risk of getting stuck in the sand.
Do not use the other modes on sand as the
vehicle may become stuck.

Height adjustment
Squeeze the control with the return and slide
the assembly on the driver's seat side and
on the individual passenger seat side.
If your vehicle is fitted with a front bench,
the height of the seat belt associated with
the centre seat cannot be adjusted.
Unfastening
Press the red button.
SEAT BELTS
Good practice
The driver must ensure that passengers
use the seat belts correctly and that they
are all strapped in securely before moving
off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
The seat belts are fitted with an inertia reel
which automatically adjusts the length of the
strap to your size.
Do not use accessories (clothes pegs, clips,
safety pins, etc.) which allow the seat belt
straps to fit loosely.
Ensure that the seat belt has reeled in
correctly after use.
After folding or moving a seat or a rear
bench seat, ensure that the seat belt has
reeled in correctly and that the buckle is
ready to accommodate the tongue.
Depending on the nature and seriousness
of any impact, the pretensioning device may
be deployed before and independently of
inflation of the airbags. It instantly tightens
the seat belts against the body of the
occupants.
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.
Fastening
Pull the strap, then insert the tongue into the
buckle.
Check that the seat belt is fastened correctly
by pulling the strap. Driver's seat belt not fastened warning
lamp
Passenger seat belt not fastened warning
lamp
When the vehicle is started, this
warning lamp comes on if the
driver has not fastened their seat
belt.
If your vehicle is fitted with a front
passenger seat, when the vehicle
is started, this warning lamp
comes on if the passenger has not
fastened their seat belt.

Seat belts
JUMPY-VU_EN_CHAP04_SECURITE_ED01-2014
The force limiter reduces the pressure of
the seat belt against the body of the
occupants.
The pretensioning seat belts are active when
the ignition is switched on.
The inertia reels are fitted with a device
which automatically locks the strap in the
event of a collision or emergency braking or
if the vehicle rolls over.
You can unfasten the seat belt by pressing
the red button on the buckle. Guide the seat
belt after unfastening.
The airbag warning lamp comes on if
the pretensioners are deployed. Contact
a CITROËN dealer or a qualified
workshop.
In order to be effective, a seat belt
must:
- restrain one person only,
- must not be twisted, check by pulling in front of you with an even
movement,
- be tightened as close to the body as possible.
The upper part of the seat belt should
be positioned in the hollow of
the shoulder.
The lap part should be placed as low as
possible on the pelvis.
Do not invert the seat belt buckles as they
will not fulfil their role completely. If the Recommendations for children:
- use a suitable child seat if the
passenger is less than 12 years old or
shorter than one metre fifty,
- never allow a child to travel on your lap, even with the seat belt fastened. FRONT SEAT BELTS
For more information on child seats,
refer to the "Children on board" section
of chapter 4.
In accordance with current safety
regulations, your CITROËN dealer can
guarantee all work or any checks, from
testing to maintenance, on your seat belt
equipment.
Have the seat belts checked regularly (even
after a minor impact) by a CITROËN dealer
or a qualified workshop: they must not show
any signs of wear, cutting or fraying and they
must not be converted or modified.
Clean the seat belt straps with soapy
water or a textile cleaning product, sold
by CITROËN dealers.
With front airbags
The front seats are fitted with pretensioners
and force limiters.
Without front airbag
If your vehicle is fitted with a front bench
without front airbag, the centre passenger's
seat belt does not have a pretensioner.
With bench seat
If your vehicle is fitted with a front bench
seat, take care to fasten the correct seat
belt using the correct buckle. Do not mix the
driver's seat belt or buckle with the buckle or
seat belt of the centre seat.
seats are fitted with armrests, the lap part of
the seat belt should always pass under the
armrest.
Check that the seat belt is fastened correctly
by pulling the strap firmly.

Airbags
JUMPY-VU_EN_CHAP04_SECURITE_ED01-2014
The airbags have been designed to
maximise the safety of the occupants in the
event of a serious collision; they work in
conjunction with the force limiting seat belts.
In the event of a serious collision, the
electronic detectors record and analyse the
front and side impacts suffered in the impact
detection zones:
- in the event of a serious impact, the airbags infl ate instantly and contribute
towards better protecting the occupants of
the vehicle. Immediately after the impact,
the airbags defl ate rapidly, so that they do
not hinder the visibility of the occupants
nor their possible exit from the vehicle. - in the event of a minor or rear impact
and in certain roll-over conditions, the
airbags will not be deployed; the seat
belt alone is sufficient to contribute
towards your protection in these
situations.
The seriousness of the collision depends on
the nature of the obstacle and the speed of
the vehicle at the moment of impact. It is imperative that the passenger's
airbag is deactivated if a child seat
is installed facing rearwards. Refer to the
"Children on board" section of chapter 4. Airbags only operate when the
ignition is switched on.

AIRBAGS
This equipment only operates once. If a
second impact occurs (during the same or
a subsequent accident), the airbag will not
operate.
The deployment of an airbag or airbags is
accompanied by a slight discharge 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 some irritation.
The noise of the detonation may result in a
slight loss of hearing for a short time.

Good practice
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 hinder the operation of
the airbags or injure the occupants.
After an accident or if the vehicle has been
stolen or broken into, have the airbag
systems checked.
All work on the airbag system is strictly
forbidden unless it is carried out by qualified
personnel at 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. In fact, 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. Lateral airbags
Only put recommended covers on the seats.
These will not hinder inflation of the lateral
airbags. Contact a CITROËN dealer or a
qualified workshop.
Do not fix or attach anything to the seat
backs. This could cause injury to the chest
or arms when the lateral airbag inflates.
Do not sit with the upper part of the body
any nearer to the door 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.
Do not allow passengers to place their feet
on the dashboard, they risk serious injury if
the airbag is deployed.
Smoke as little as possible 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.

If this warning lamp comes
on in the instrument panel,
accompanied by an audible signal
and a message in the screen,
contact a CITROËN dealer or
a qualified workshop to have the system
checked. The airbags may no longer be
deployed in the event of a serious impact.
Lateral airbags
If fitted on your vehicle, this is a system
which protects the driver and front
passenger in the event of a serious side
impact in order to limit the risk of injury to
the chest.
Each lateral airbag is fitted in the front seat
back frame, on the door side. Impact detection zones
A. Front impact zone.
B. Side impact zone.
In the event of a minor impact or bump
on the side of the vehicle or if the
vehicle rolls over, the airbag may not be
deployed.
The airbag is not deployed in the event of a
rear or front collision. Operating fault
Deployment
It is deployed unilaterally in the event of a
serious side impact applied to all or part
of the side impact zone B , perpendicular
to the longitudinal centreline of the vehicle
on a horizontal plane and directed from the
outside towards the inside of the vehicle.
The lateral airbag inflates between the
front occupant of the vehicle and the
corresponding door trim panel.

Deactivation
The passenger's front airbag alone can be
deactivated:
- with the ignition switched off , insert the key into the passenger's airbag
deactivation switch,
- turn it to the "OFF" position,
- then remove the key keeping the switch in the new position. Front airbags
The front airbags are fitted in the centre of
the steering wheel for the driver and in the
dashboard for the front passenger. Reactivation
In the
"OFF" position, the passenger's
airbag will not be deployed in the event of
an impact.
As soon as the child seat is removed, turn
the airbag switch to the "ON" position to
reactivate the airbag and thus ensure the
safety of your passenger in the event of an
impact. To ensure the safety of your child, it is
essential to deactivate the passengers
airbag when you install a rear-facing child
seat on the front passenger seat. Otherwise,
the child would risk being killed or seriously
injured if the airbag were to inflate.
The airbag warning lamp in the
instrument panel is on while the
airbag is deactivated.
Deployment
They are deployed, except the passenger's
front airbag if it has been 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 directed from the front
towards the rear of the vehicle.
The front airbag inflates between the front
occupant of the vehicle and the dashboard
to cushion their forward movement. If this warning lamp comes on,
accompanied by an audible signal
and a message in the screen,
contact a CITROËN dealer or
a qualified workshop to have the system
checked. Front airbag fault
If the two airbag warning lamps are on
continuously, do not install a "rearward
facing" child seat. Contact a CITROËN or a
qualified workshop.
