Safety
Associated systems which guarantee the directional stability of the vehicle within the limits of the laws of physics:
- traction control (TCL),
- active 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 automaticallyeach time the vehicle is started.
The illumination o
f 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 movefreely and regain grip.
This is indicated b
y flashing of this symbol on the instrument panel screen.
Trajectory control systems
)Press this button, located to the right of thesteering 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.
