F Press briefly upwards or downwards, without going beyond the point of
resistance; the direction indicators will
flash 3 times.
Hazard warning lamps
A visual warning by means of the direction
indicators to alert other road users to a vehicle
breakdown, towing or accident.

ress this button, the direction indicators
flash.
They can operate with the ignition off.
If you forget to cancel the
direction indicators for more than
twenty

seconds, the volume of the
audible signal will increase if the speed
is above 40 mph (60 km/h).

Automatic operation of
hazard warning lamps
When braking in an emergency, depending on
the deceleration, the hazard warning lamps
come on automatically.
They switch off automatically the first time you
accelerate.
F
Y
ou can also switch them off by pressing
the button.
Horn
Audible warning system to alert other road
users to an imminent danger.

P
ress the central part of the multifunction
steering wheel.
Use the horn moderately and only in
situations allowed by the motoring
regulations in the country you are
driving in.
Emergency or
assistance call
This system allows you to make an emergency
or assistance call to the emergency services or
to the dedicated CITROËN service.
For more information on the use of this
function, refer to the "Audio and telematics"
section.
Safety

Braking assistance systems
Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-
a
nti-lock braking system (ABS),
-

e
lectronic brake force distribution (EBFD),
-

e
mergency 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 sur faces.
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. When braking in an emergency,
press very firmly without releasing
the
pressure.
Operating fault
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.
You must stop as soon as it is safe to do so.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.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.
In either case, contact a CITROËN dealer or a
qualified workshop.

173
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
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")
Depending on version, 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.
Safety

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
P
ress this button, located near the steering
wheel.
If the indicator lamp in the button comes on, this
indicates that these systems are deactivated.
Reactivation
These systems are reactivated automatically
each time the ignition is switched back on or
from 30 mph (50 km/h).
F

P
ress this 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:
-

w
heels (tyres and rims),
-

b
raking components,
-
el

ectronic components,
-

a
ssembly and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
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.
It is recommended that the systems be
reactivated as soon as possible. Have it checked by a CITROËN dealer or a
qualified workshop.
