CITROEN C-ZERO Handbook page 51

The warning lamp comes on for a few
seconds when switching on (ON position).
If it does not go out or come on, contact a
CITROËN dealer or a qualified workshop.
Moving vehicle
If this warning lamp remains on
constantly, it indicates an anti-lock
braking system malfunction that
could cause control of the vehicle to
be lost during braking.
You must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop.
If both these warning lamps come
on, they indicate a malfunction in the
electronic brake force distribution
that could cause control of the
vehicle to be lost during braking.
You must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop.
When replacing wheels (tyres and rims),
ensure that they comply with manufacturer
recommendations.
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.
In emergency braking, press very firmly
and maintain this 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 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
every time the vehicle is started.
They come into operation in the event of a
problem with grip or trajectory.
This is indicated by flashing of this
warning lamp in the instrument
panel.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR and DSC systems, so that the wheels
can regain grip.
F Press this button until the corresponding
symbol appears in the instrument panel.
The display of this symbol indicates
that the ASR and DSC systems are
deactivated.
