Brake assist system
The Brake Assist System (BAS) increases brak-
ing force, thereby helping reduce braking dis-
tance.
The system monitors the driver's braking habits
and increases braking force when necessary.
Brake force can be increased up to the point at
which the ABS system is activated. The function
is deactivated when pressure on the brake pedal
decreases.

Braking effect after a collision
In certain types of collisions, the vehicle's brakes
are applied to help prevent or mitigate a secon-
dary collision.
Maintaining control of the vehicle after a collision
may be difficult. To help avoid or mitigate the
effect of a secondary collision, the brakes are
applied automatically to help bring the vehicle to
a stop.
The brake lights and hazard warning flashers will
be activated and the flashers will remain on after
the vehicle has come to a standstill. The parking
brake will then be applied automatically.
In a situation where stopping the vehicle may not
be desirable, the driver can override this system
by pressing the accelerator pedal.
This feature can only function if the brake system
is intact after the collision.
