2012 Citroen DS4 ESP

179Safety
Emergency braking assistance
System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.

Activation

It is triggered by the speed at which the brake pedal is pressed.
The effect of this is a reduction in theresistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press firmly without releasing the pressure.

















Trajectory control systems (ESP)
Anti-slip regulation (ASR)
and electronic stability
control (ESC)
The anti-slip regulation (also known as traction control) optimises traction to prevent skidding
of the wheels, by acting 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 automaticallyeach time the vehicle is started.
They come into operation in the event of a gripor trajectory problem.
This is indicated b
y flashing of this
warning lamp in the instrument panel.

Intelligent traction control
s
ystem ("Snow motion")
Your vehicle has a system to help driving on snow: intelligent traction control.
This system detects situations of difficult surface adhesion that could make it difficult to
move off or make progress on deep fresh snowor compacted snow.
In these situations, the intelligent tractioncontrol 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 offering low levels of adhesion.

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.

Rear seat belts

Fastening
)Pull the strap, then inser t the tongue in thebuckle.)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.)On the outer seat belts, raise the bar to the
top of the backrest to prevent the tongue from knocking against the side trim.
The rear seats are each fitted with a three-point
seat belt, with force limiter and, for the outer
seats
, an effort limiter.

5. Left hand rear 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 5
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 3,4and 5come on in red, accompanied by anaudible signal and a message in the screen, if a rear passenger has unfastened their seat belt. From approximatel
y 12 mph (20 km/h),
this warning lamp flashes for two minutes
accompanied by an audible signal of increasingvolume. Once these two minutes have elapsed,
this warning lamp remains on until the one or more rear passengers fasten their seat belt.

Lateral airbags
System which protects the driver and frontpassenger in the event of a serious side impact
in order to limit the risk of injury to the chest,
between the hip and the shoulder.
Each lateral airba
g is fitted in the seat backrest frame, door side.

Deployment
Impact detection zones
A.Front impact zone.
B.Side impact zone. The lateral airba
gs are deployed unilaterally in
the event of a serious side impact applied to all
or par t 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 hip and
shoulder of the front occupant of the vehicle
and the corresponding door trim panel.

189Safety
Curtain airbags
System which protects the driver andpassengers (with the exception of the rear centre passenger) in the event of a serious side
impact in order to limit the risk of injury to theside of the head.
Each curtain airbag is built into the pillars andthe upper passenger compartment area.

Deployment

The cur tain airbag is deployed at the same
time as the corresponding lateral airbag in the event of a serious side impact applied to all or par t 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 cur tain airbag inflates between the front or
rear occupant of the vehicle and the windows.
Operating fault
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.
In the event of a rear or front collision, the airbag is not deployed.
I
f this warning lamp comes on in theinstrument 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.

Gear shift indicator *
Operation
The system intervenes only when driving economically.
Depending on the driving situation and your
vehicle's equipment, the s
ystem may advise you to skip one or more gears. You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations mustnot be considered compulsory. In fact, the configuration of the road, the amount of trafficand safety remain determining factors whenchoosing the best gear. Therefore, the driver remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.

- The s
ystem may suggest that you engage a
higher gear, if appropriate.
The in
formation appears in the instrument panel in the form of an arrow accompanied bythe suggested gear.


In the case of driving which makespar ticular demands on the performance of the engine (firm pressure on theaccelerator pedal, for example, whenover taking...), the system will notrecommend a gear change. The system never suggests:


- engaging first gear,

- engaging reverse gear,

- engaging a lower gear.
*
According to engine.
Example:


- You are in third gear.

-
You press the accelerator pedalmoderately.
