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.

Checks
Brake wear depends on the style
of driving, par ticularly in the case
of vehicles used in town, over shor t
distances. It may be necessary tohave the condition of the brakes checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake pads are worn.
Brake pads
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Brake disc wear
Parking brake
If excessive travel or a loss of effectiveness of this system isnoticed, the parking brake must be
checked, even between two services.
Only use products recommended by CITROËN or products of equivalent quality and specification.
In order to optimise the operationof units as impor tant as the brakingsystem, CITROËN selects and offers very specific products. To a v o i d d a m aging the electrical units, the use of a high pressure washer in the engine compar tment is strictlyprohibited.
Checking this system must be done by aCITROËN dealer or a qualified workshop.
