system operation check is being performed, and is not an abnormality.

distance)For road surfaces suck as snow-covered roads an gravel roads, the
braking distance for vehicles with ABS can sometimes be longer than

on suck roads by lowering the vehicle speed and not being to
overconfident.
Shock during system operation

driving speed. This occurs due to ABS operation check (initial check at
a vehicle speed of 8 km/h), and does not indicate any malfunction.
