Emergency braking ass
istance

System which, in an emergency, enables you to o
btain the opt
imum
braking pressure more
quickly, thus reducing the stopping distance.
Activation
It is triggered by the speed at which the brake pedal is presse
d.

The effect of this is a reduction in the resistance of the pedal and an increase in braking efficiency.

When braking in an emergency, press firmly without releasing the pressure.

of driving,
-
snow
