Trajectory Control Systems - CITROËN C3 PICASSO Handbook

Safety

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.

Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate the
DSC and ASR systems, so that the wheels can
move freely and regain grip.
F Press the button, located in the centre of
the dashboard.
If this warning lamp comes on in the
instrument panel and the indicator
lamp on the button comes on, this
indicates that the dSC and aSR
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 Press the button again to reactivate them
manually.
Operating fault
If this warning lamp comes on,
accompanied by an audible signal
and a message in the multifunction
screen, this indicates a malfunction
of these systems.
Have it checked by a CITRoËn dealer or a
qualified workshop.
The dSC/aSR systems offer
exceptional safety in normal driving, but
this should not encourage the driver to
take extra risks or drive at high speed.
The correct operation of these
systems depends on observation of
the manufacturer's recommendations
regarding wheels (tyres and rims),
braking components, electronic
components and assembly and repair
procedures.
after an impact, have these systems
checked by a CITRoËn dealer or a
qualified workshop.
