Driving and parking 141
Limited braking effect on salt-treated roads:
Due to salt build-up on the brake discs and
R
brakepads, the braking distance can increase
considerably or result in braking only on one
side
Maintain a much greater safe distance to the
R
vehicle in front
To remove the layer of salt:
Brake occasionally while paying attention to
R
the traffic conditions
Carefully depress the brake pedal at the end
R
of the journey and when starting the next
journey
Function of rear axle steering
Depending on the speed, rear axle steering
adapts the track of the rear axle to the position
of the front wheels. Together with the steering
input of the front wheels, this results in greater
mobility and improved stability.
