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