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).
Braking assistance systems
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 is active if the
vehicle speed is higher than 6 mph (10 km/h).
It is deactivated when the vehicle speed falls
below 3 mph (5 km/h).
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
When the vehicle is stationary
If this warning lamp comes on, accompanied by
the indication on the instrument panel screen, it
indicates a malfunction of the anti-lock braking
system which could result in a loss of control of
the vehicle when braking.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or a qualified workshop as
soon as possible.
When braking in an emergency, press
very firmly without releasing the
pressure. The warning lamp comes on for a few
seconds when the ignition is switched on
(ON position). If it does not switch off or
does not come on, contact a CITROËN
dealer or a qualified workshop.

When the vehicle is moving
If this warning lamp comes
on continuously it indicates a
malfunction of the anti-lock braking
system which could result in a loss of
control of the vehicle on braking.
The two warning lamps comes on at the
same time and the two warnings are
displayed alternately in the instrument
panel screen.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or qualified workshop as
soon as possible.
If these two warning lamps come on, linked
with the warnings on the instrument panel
screen, they indicate a malfunction of the
electronic brake force distribution which could
result in a loss of control of the vehicle on
braking.
You must stop as soon as it is safe to do so.

Associated systems which guarantee the directional stability of the vehicle within the limits of the laws of physics:
- t raction control (TCL),
-

a
ctive stability control (ASC).
Traction control and active stability control
Traction control optimises traction to prevent
wheel spin, by acting on the brakes of the
driving wheels and on the engine.
Active 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.Activation
These systems are activated automatically
each time the vehicle is started.
The illumination of this warning lamp
in the instrument panel indicates
that the ASC and TCL systems are
deactivated.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, ...), it may be advisable to deactivate
the ASC system, so that the wheels can move
freely and regain grip.
This is indicated by flashing of this
symbol on the instrument panel
screen.
Trajectory control systems
F Press this button, located to the left of the steering wheel, until the symbol appears in
the instrument panel screen.
Operation
They operate when the vehicle speed is higher
than 10 mph (15 km/h).
They come into operation in the event of a grip
or trajectory problem.

ground.
Apply the parking brake, switch off the
ignition and engage first gear to lock
the wheels.
If necessary, place a chock under the
wheel diagonally opposite the wheel to
be changed.
Never go underneath a vehicle raised
using a jack; use a stand.

For more information on snow chains,
contact a CITRoËn dealer or a
qualified workshop.
Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when
braking.
Advice on installation
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face
on the side of the road.
F

A
pply the parking brake and position any
wheel chocks to prevent movement of your
vehicle.
F

F
it the chains following the instructions
provided by the manufacturer.
F

M
ove off gently and drive for a few
moments, without exceeding 30 mph
(50
km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened.
The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels.
Take account of the legislation in force
in your country on the use of snow
chains and the maximum running speed
authorised.
Avoid driving with snow chains on roads
that have been cleared of snow, to
avoid damaging your vehicle's tyres and
the road sur face. If your vehicle is fitted
with alloy wheels, check that no part of
the chain or its fixings is in contact with
the wheel rim.Use only chains designed for fitment to the type
of road wheels on your vehicle:
Original equipment tyre size Maximum link size
215/70 R16 12 mm
225/55 R18
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.
