2010.5 Citroen DS4 DAG ignition

Deactivation
In exceptional conditions (star ting a vehicle which is bogged down, stuck in snow, on soft ground...), it may be advisable 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.
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 ESP/ASR systems offer exceptional safety in normal driving, but this should not encourage the driver to take extra risks or drive at high speed. The correct functioning of these systems is assured provided that manufacturer's recommendations are obser ved 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.
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 qualified workshop.

Safety
Seat belts
Front seat belts
The front seat belts are fitted with a pretensioning and force limiting system. This system improves safety in the front seats in the event of a front or side impact.
Depending on the severity of the impact, the pretensioning 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 fastened
correctly by pulling the strap.
Unfastening
 Press the red button on the buckle.  Guide the seat belt as it reels in.
Seat belt not fastened/unfastened warning lamp
When the ignition is switched on, this warning lamp comes on in the instrument panel if the driver and/or the front passenger has not fastened their seat belt. From approximately 12 mph (20 km/h) this warning lamp flashes for two minutes accompanied by an audible signal of increasing volume. Once these two minutes have elapsed, this warning lamp remains on until the driver and/
or the front passenger fastens their seat belt.
Height adjustment
 To lower the attachment point, squeeze the control A and slide it downwards.  To raise the attachment point, slide the control A upwards.

Safety
Seat belt unfastened warning lamp
This warning lamp comes on in the instrument panel when one or more rear passengers unfasten their seat belt. From approximately 12 mph (20 km/h), this warning lamp flashes for two minutes accompanied by an audible signal of increasing volume. Once these two minutes have elapsed, this warning lamp remains on until the one or more rear passengers fasten their seat belt.
Seat belt unfastened warning lamps display
3. Rear right seat belt warning lamp. 4. Rear centre seat belt warning lamp. 5. Rear left seat belt warning lamp. When the ignition is switched on, with the engine running or when the vehicle is moving at less than 12 mph (20 km/h), the corresponding warning
lamps 3 , 4 and 45 come on in red for approximately 30 seconds, if the seat belt is not fastened. When the vehicle is moving at more than 12 mph
(20 km/h), the corresponding warning lamps 3 , 4 and 5 come on in red, accompanied by an audible signal and a message in the screen, if a rear passenger has unfastened their seat belt.

181Safety
Airbags
System designed to maximise the safety of the occupants (with the exception of the rear centre passenger) in the event of violent collisions. It supplements the action of the force-limiting seat belts (with the exception of the rear centre passenger). 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 airbags are deployed instantly and protect the occupants of the vehicle (with the exception of the rear centre passenger); immediately after the impact, the airbags deflate rapidly so that they do not hinder visibility or the exit of the occupants, - in the case of a minor or rear impact or in cer 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 the ignition is switched off. This equipment will only deploy once. If a second impact occurs (during the same or a subsequent accident), the airbag will not be deployed again.
Impact detection zones
A. Front impact zone. B. Side impact zone.
Deployment of the airbag(s) is
accompanied by a slight emission of harmless smoke and a noise, due to the activation of the pyrotechnic car tridge incorporated in the system. This smoke is not harmful, but sensitive individuals may experience slight irritation. The noise of the detonation may result in a slight loss of hearing for a shor t time.

183Safety
Deactivation
Only the passenger's front airbag can be deactivated:  with the ignition off , inser t the key in the n offpassenger airbag deactivation switch,  turn it to the "OFF" position,  then, remove the key keeping the switch in the new position.
According to version, this warning lamp comes on either in the instrument panel or in the seat belt and passenger's front airbag warning lamps display when the ignition is on and until the airbag is reactivated.
To assure the safety of your child, the passenger's front airbag must be deactivated when you install a "rear facing" child seat on the front
passenger seat. Other wise, the child would risk being seriously injured or killed if the airbag were deployed.
Reactivation
When you remove the child seat, turn the switch to the "ON" position to reactivate the airbag and so assure the safety of your front passenger in the event of an impact.
With the ignition on, this warning
lamp comes on in the seat belt and passenger's front airbag warning lamps display for approximately one minute, if the passenger's front airbag is activated.
Operating fault
If this warning lamp flashes, contact a CITROËN dealer or a qualified workshop. The passenger's front airbag may no longer be deployed in the event of a serious impact.
If even one of the two airbag warning lamps comes on continuously, do not install a child seat on the front passenger seat. Have the system checked by a CITROËN dealer or a qualified workshop.
If this warning lamp comes on in the instrument panel, accompanied by an audible warning 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.

If you pull control lever A without pressing the brake pedal, the parking brake will not be released and a warning lamp will come on in the instrument panel.
Maximum application
If necessary, you can make a maximum application of the parking brake. This is obtained by means of a long pull on the control lever A , until you see the message "Handbrake on maximum" and a beep is heard. Maximum application is essential: - in the case of a vehicle towing a caravan or a trailer, if the automatic functions are activated but you are applying the parking brake manually, - when the gradient you are parked on may vary (e.g. on a ferry, on a lorry, during towing),
In the case of towing, a loaded vehicle or parking on a gradient, make a maximum application of the parking brake then turn the front wheels towards the pavement and engage a gear when you park. After a maximum application, the release time will be longer.

With the vehicle stationary, the parking brake is automatically applied when the engine is switched off.
Automatic application,
engine off
In the case of towing, a loaded vehicle or parking on a gradient, turn the front wheels towards the pavement and engage a gear when you park.
