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 TRC systems, so that the wheels can
spin freely and regain grip.
However, it is recommended that theses
systems be reactivated as soon as possible.
Deactivation of the TRC system only
F Press this button briefly.
This warning lamp comes on: the
TRC system no longer acts on the
operation of the engine.
Deactivation of the TRC and DSC systems
F Vehicle stationary, press this
button for at least than 3 seconds.
These warning lamps come
on: the TRC and DSC
systems no longer act on
the operation of the engine.
Reactivation
The TRC and DSC control systems are
reactivated automatically every time the engine
is started.
F Press the button again to
reactivate it manually.
When the TRC system only is deactivated, it is
reactivated as the vehicle's speed increases.
When both the TRC and DSC systems are
deactivated, they do not reactivate themselves
even if the speed of the vehicle increases.
Operating fault
Illumination of this warning lamp,
accompanied by an audible signal,
indicates a fault with the system.
Drive carefully at reduced speed and contact
a CITROËN dealer or a qualified workshop to
have the system checked.
The TRC and DSC systems offer
increased safety in normal driving, but
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 the wheels (tyres and rims),
the braking components, the electronic
components and the assembly and
repair procedures used by CITROËN
dealers.
After an impact, have the system
checked by a CITROËN dealer or a
qualified workshop.
