ignition Citroen DS4 2012 1.G Workshop Manual

Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on softground...), if you are unable to make progress,it may be advisable to temporarily deactivate
these systems, so that the wheels can spinfreely and allow the vehicle to move.
) Press the "ESP OFF"
button,located near the steering wheel.

Reactivation
These systems are reactivated automatically 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.

Operating fault

The trajectory control systems offer increased safety in normal driving, butthis should not encourage the driver to take extra risks or drive at high speed.
The correct functioning of these systems is assured provided thatmanufacturer's recommendations areobserved 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.
I
f 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 aqualified workshop.
It is recommended that the systems bereactivated as soon as possible.
If this warnin
g lamp comes on in the instrumentpanel and the indicator lamp in the buttoncomes on, this indicates that these systems aredeactivated.

Safety
Seat belts


Front seat belts


The front seat belts are fitted with apretensioning and force limiting system.
This system improves safety in the frontseats in the event of a front or side impact.
Dependin
g on the severity of the impact, thepretensioning system instantly 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 occupant, so improving their protection.

Fastening
)Pull the strap, then inser t the tongue in the buckle.)Check that the seat belt is fastenedcorrectly by pulling the strap.



Unfastening
)Press the red button on the buckle.)Guide the seat belt as it reels in.

Safety
Airbags


System designed to maximise the safety of the
occupants (with the exception of the rear centrepassenger) in the event of violent collisions.
It supplements the action of the force-limiting
seat belts (with the exception of the rear centrepassenger).
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 airbagsare deployed instantly and protect the
occupants of the vehicle (with the exception
of the rear centre passenger); immediatelyafter the impact, the airbags deflate rapidlyso that they do not hinder visibility or theexit of the occupants,

- in the case of a minor or rear impact or incer tain roll-over conditions, the airbags
will not be deployed; the seat belt alone is sufficient to provide optimum protection in
these situations.
The airbags do not operate when theignition is switched off.This equipment will only deploy once. If a second impact occurs (during the same or a subsequent accident), theairbag will not be deployed again.


Impact detection zones
A.Front impact zone.
B. Side impact zone.

Deployment of the airbag(s) isaccompanied by a slight emissionof harmless smoke and a noise, dueto the activation of the pyrotechnic cartridge incorporated in the system.
This smoke is not harmful, but sensitive individuals may experience slightirritation.
The noise of the detonation may result ina slight loss of hearing for a shor t time.
