Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the

If th e brakes ha vebeen used only moderatel y,
yo u should occasionally test their ef fectiveness.
To do this, brake more firm lyfrom a higher speed
while paying attention tothe tra ffic conditions.
The brakes will grip better as a result.

While paying attention tothe tra ffic conditions,
yo u should brake theve hicle firm ly af ter driving
