Under-inflation detection

The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised every time the
tyre pressures are adjusted or a wheel
changed

The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres.

The under-inflation detection system
does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous condition
(high loading, high speed, long journey).

System which automatically checks the pressures of the tyres while driving.

The inflation pressures defined for
your vehicle can be found on the tyre
pressure label.
For more information on the
identification markings, refer to the
corresponding section.
Tyre pressures should be checked
when the tyres are "cold" (vehicle
stopped for 1 hour or after a journey of
less than 6 miles (10 km) at moderate
speeds).
Otherwise (when hot), add 0.3 bar to
the pressures shown on the label.

Driving with under-inflated tyres
increases fuel consumption.

Under-inflation alert

This is given by fixed illumination of
this warning lamp, accompanied by
an audible signal.

Reduce speed immediately, avoid

excessive steering movements and sudden
braking.

F Stop the vehicle as soon as it is safe to

do so.

The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a visual
check.

If you have a compressor (such as the one

in the temporary puncture repair kit) check
the pressures of the four tyres when cold.

If it is not possible to carry out this check
straight away, drive carefully at reduced
speed.

or
F In the event of a puncture, use the

temporary puncture repair kit or the spare
wheel (depending on equipment).

The alert is maintained until the system
is reinitialised.

Reinitialisation

Before reinitialising the system, ensure
that the pressures of the four tyres are
correct for the use of the vehicle and in
line with the recommendations on the
tyre pressure label.
The under-inflation alert can only be
relied on if the reinitialisation of the
system has done with the pressures in
the four tyres correctly adjusted.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.

It is necessary to reinitialise the system every
time one or more tyre pressures are adjusted,
and after changing one or more wheels.
A label attached to the middle pillar, driver's
side, gives a reminder of this.

Driving

C1_en_Chap04_conduite_ed01-2016

The under-inflation alert can only be
considered reliable if reinitialisation of
the system is done with the the four tyre
pressures correctly set.

Snow chains

The system does not have to be
reinitialised after fitting or removing
snow chains.

Operating fault

The flashing and then fixed illumination
of the under-inflation warning lamp
indicates a fault with the system.

In this case, under-inflation monitoring of the
tyres is no longer assured.
Have the system checked by a CITROËN
dealer or a qualified workshop.

Before doing anything to the system,
the pressures of the four tyres must be
checked and the system reinitialised.

Reinitialisation of the system is done with the
ignition on

(ignition switch in the "ON" position

or "ON

" mode) and the vehicle stationary.

Open the glove box.

Press the reinitialisation button.

The new pressure settings registered
are considered to be reference values by
the system.

This warning lamp flashes

3 times in the instrument panel
when the reinitialisation is done.

Wait a few minutes before switching off the

ignition (ignition switch in the "ACC"
or "LOCK" position, or "OFF

" mode).

Lighting and visibility

Exterior lighting control stalk

Main lighting

The various front and rear lamps of the vehicle
are designed to adapt the driver's visibility
progressively according to the ambient light
level and weather:
- sidelamps, to be seen,
- dipped beam headlamps to see without

dazzling other drivers,

- main beam headlamps to see clearly when

the road is clear.

Additional lighting

Other lamps are provided to meet the
requirements of particular driving conditions:
- a rear foglamp,
- daytime running lamps to be more visible

during the day.

In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal surface of the
glass of the headlamps and rear lamps
is normal; it disappears after the lamps
have been on for a few minutes.

Travelling abroad

If using your vehicle in a country that
drives on the other side of the road, the
headlamps must be adjusted to avoid
dazzling on-coming drivers.
Contact a CITROËN dealer or a
qualified workshop.

Electronic Stability Control (ESC) incorporating
the following systems:
- anti-lock braking system (ABS) and the

electronic brake force distribution (EBFD),

-  emergency braking assistance,
-  traction control (TRC),
-  dynamic stability control (DSC).

Electronic stability control (ESC)

Definitions

Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)

These systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards better control in
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.

Emergency braking assistance

In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered according to the speed at which
the brake pedal is pressed. This is felt by a
reduction in the resistance of the pedal and an
increase in the effectiveness of the braking.

Traction control (TRC)

This system optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.

Dynamic stability control (DSC)

If there is a difference between the path
followed by the vehicle and that required by the
driver, this system monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.

108

Safety

C1_en_Chap06_securite_ed01-2016

Illumination of this warning lamp,
accompanied by an audible signal,
indicates that there is a fault with the
electronic brake force distribution
(EBFD), which could cause loss of
control of the vehicle when braking.

Operation

Illumination of this warning lamp,
accompanied by an audible signal,
indicates that there is a fault with
the ABS system, which could cause
loss of control of the vehicle when
braking.

Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)

When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal.

In emergency braking, press
very firmly without releasing
the pressure.

You must

stop as soon as it is safe to do so.

Contact a CITROËN dealer or a qualified
workshop as soon as possible.

Dynamic stability control (DSC)
and traction control (TRC)

Activation

These systems are activated automatically
each time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation if
the engine and brakes.

Activation of the DSC system is
signalled by the flashing of this
indicator lamp in the instrument panel,
accompanied by an audible signal.

Activation of the TRC system is
signalled by the flashing of this
indicator lamp in the instrument panel.

Drive carefully at reduced speed, and contact a
CITROËN dealer or a qualified workshop.

109

Safety

C1_en_Chap06_securite_ed01-2016

The TRC and DSC systems offer
increased safety in normal driving, but
should not encourage the driver to take
extra risks or drive at high speed.
The correct operation of these
systems depends on observation of
the manufacturer's recommendations
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the assembly and
repair procedures used by CITROËN
dealers.
After an impact, have the system
checked by a CITROËN dealer or a
qualified workshop.

Deactivation

In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate the
DSC and TRC systems, so that the wheels can
spin freely and regain grip.

Operating fault

However, it is recommended that these
systems be reactivated as soon as possible.

Press this button briefly.

This warning lamp comes on: the
TRC system no longer acts on the
operation of the engine.

Reactivation

The TRC and DSC control systems are
reactivated automatically every time the engine
is started.

Press the button again to

reactivate it manually.

Illumination of this warning lamp,
accompanied by an audible signal,
indicates a fault with the system.

Drive carefully at reduced speed and contact
a CITROËN dealer or a qualified workshop to
have the system checked.

Deactivation of the TRC system only

Deactivation of the TRC and DSC systems

F Vehicle stationary, press this

button for at least than 3 seconds.

These warning lamps come
on: the TRC and DSC
systems no longer act on
the operation of the engine.

When the TRC system only is deactivated, it is
reactivated as the vehicle's speed increases.

When both the TRC and DSC systems are
deactivated, they do not reactivate themselves
even if the speed of the vehicle increases.

Active City Brake

Active City Brake is a driving assistance system
that aims to avoid a frontal collision or reduce
the speed of an impact if the driver does not
react or reacts too late (brake application too
late).

This system is designed to improve
driving safety.
It remains the driver's responsibility to
continuously monitor the state of the
traffic and to assess the distances and
relative speeds of other vehicles.
Active City Brake can in no
circumstances replace the need for
vigilance on the part of the driver.

Never look at the laser sensor through
an optical instrument (magnifying glass,
microscope...) at a distance of less than
10 centimetres: risk of eye injury.

Automatic braking occurs later than if
done by the driver, so as to intervene
only when there is a high risk of
collision.

Principle

Using a laser sensor and a camera located at
the top of the windscreen, this system detects
a vehicle running in the same direction or
stationary ahead of your vehicle.
When necessary, the vehicle's braking system
is operated automatically to reduce the speed
of impact or to help avoid a collision with the
vehicle ahead.

Conditions for activation

Active City Brake only operates if the following
conditions are met:
●  the engine is running,
●  the vehicle is in a forward gear,
●  to trigger the pre-collision alert:

- the speed is between 9 and 87 mph

(15 and 140 km/h),

- the difference in speed between your

vehicle and the one ahead is more than
about 9 mph (15 km/h),

● for braking assistance:

- the speed is between about 18 and

50 mph (30 and 80 km/h),

- the difference in speed between your

vehicle and the one ahead is more than
about 18 mph (30 km/h),

● for automatic pre-collision braking:

- the speed is between about 6 and

50 mph (10 and 80 km/h),

- the difference in speed between your

vehicle and the one ahead is more than
about 6 mph (10 km/h),

● the braking assistance systems (ABS,

EBFD, EBA) are not faulty,

● the trajectory control systems (TRC, DSC)

are not deactivated or faulty,

● the vehicle is not in a tight corner,
● the system has not been triggered during

the previous 10 seconds.
