Safety









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 the
resistance 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 automatically
each time the vehicle is star ted.
They come into operation in the event of a grip
or trajectory problem.
This is indicated by flashing of this
warning lamp in the instrument panel.








Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving on
snow: intelligent traction control.

This system detects situations of difficult
sur face adhesion that could make it difficult to
move off or make progress on deep fresh snow
or compacted snow.
In these situations, the intelligent traction
control
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 sur faces offering low
levels of adhesion.

Deactivation

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), if you are unable to make progress,
it may be advisable to temporarily deactivate
these systems, so that the wheels can spin
freely 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, 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
observed 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. It is recommended that the systems be
reactivated as soon as possible.
If this warning lamp comes on in the instrument
panel and the indicator lamp in the button
comes on, this indicates that these systems are
deactivated.

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.

Electric parking brake


The electric parking brake combines
2 operational modes:


- Automatic Application/Release

Application is automatic when the engine
stops, release is automatic on use of the
accelerator (activated by default),

- Manual Application/Release

The parking brake can be applied/released
manually by pulling control lever A
.
Do not place any object (packet of
cigarettes, telephone...) between the
gear lever and the electric parking
brake control lever.
It is recommended that you do not
apply the parking brake in very cold
conditions (ice) and during towing
(breakdown, caravan...). Deactivate the
automatic functions and release the
parking brake manually.

If this warning lamp comes on in
the instrument panel, the automatic
mode is deactivated.

Programming the mode

Depending on the country of sale of the vehicle,
the automatic application when the engine is
switched off and the automatic release when
you press the accelerator can be deactivated.
Activation/deactivation is done
using the vehicle configuration
menu; refer to the section covering
the configuration of your vehicle's
systems.
The parking brake is then applied and released
manually. When the driver's door is opened,
there is an audible signal and a message is
displayed if the brake is not applied.

193Driving
With the ignition on or the engine running, to
release the parking brake, press
on the brake

pedal
or the accelerator, pull then release

control A
.


Manual release


Before leaving the vehicle, ensure
that parking brake warning lamp in
the instrument panel is on fixed, not
flashing.



Manual application

With the vehicle stationary, to apply the parking
brake whether the engine is running or off, pull

control lever A
.
The application of the parking brake is
confirmed by:


- illumination of the braking warning
lamp and of the P
warning lamp in
the control lever A
,

- display of the message
"Handbrake on".
When the driver’s door is opened with the
engine running, a message is displayed
accompanied by an audible signal if the parking
brake has not been applied, except in the case
of an automatic gearbox with the gear lever in
position P
. The full application of the parking brake is
confirmed by:


- the braking warning lamp and
the P
warning lamp in the control
lever A
going off,

- display of the message
"Handbrake off".

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.
