In good or rainy weather, by both day
and night, the front foglamps and the
rear foglamps are prohibited. In these
situations, the power of their beams
may dazzle other drivers. They should
only be used in fog or falling snow.
In these weather conditions, you should
switch on the foglamps and dipped
beam headlamps manually, as the
sunshine sensor may detect sufficient
light.
Do not forget to switch off the front and
rear foglamps when they are no longer
necessary.

Switching off the lighting when
switching off the ignition

When the ignition is switched off, all of the
lamps switch off immediately, except for
the dipped beam headlamps if automatic
guide-me-home lighting is activated.

Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
- anti-lock braking system (ABS),
- electronic brake force distribution (EBFD),
- emergency braking assistance (EBA).

Anti-lock braking system
and electronic brake force
distribution

Linked systems which improve the stability and
manoeuvrability of your vehicle when braking, in
particular on poor or slippery surfaces.

Activation

The anti-lock braking system comes into
operation automatically when there is a risk of
wheel lock.
Normal operation of the ABS may make itself
felt by slight vibration of the brake pedal.

Operating fault

If this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, it
indicates a malfunction of the anti-
lock braking system which could
result in loss of control of the vehicle
when braking.
If this warning lamp comes on,
together with the STOP and ABS
warning lamps, accompanied by an
audible signal and a message in the
screen, it indicates a malfunction of
the electronic brake force distribution
which could result in loss of control of
the vehicle when braking.

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.

You must stop as soon as it is safe to do so.
In either case, contact a CITROËN dealer or a
qualified workshop.

When braking in an emergency, press
very firmly without releasing the
pressure.

When braking in an emergency, press
firmly without releasing the pressure.

When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.

Trajectory control systems

Anti-slip regulation (ASR)
and dynamic stability
control (DSC)

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 started.
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")

Deactivation

In extremely severe conditions (deep snow,
mud, ...), if you are unable to move off, it may
be useful to temporarily deactivate these
systems so that the wheels can spin freely and
allow the vehicle to move.

F

Press this button, located near the steering

wheel.

If the indicator lamp in the button comes on, this
indicates that these systems are deactivated.

Depending on version, 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 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.

It is recommended that the systems be
reactivated as soon as possible.

The use of snow tyres is strongly
recommended on surfaces offering low
levels of adhesion.

Safety

142

C4-2_en_Chap05_securite_ed02-2015

Reactivation

These systems are reactivated automatically
each time the ignition is switched back on or
from 30 mph (50 km/h).
F

Press this button again to reactivate them

manually.

The illumination of the indicator
lamps in the instrument panel and
in this button, accompanied by an
audible signal and a message in the
screen, indicates a fault with these
systems.

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.
