hands off the steering wheel for a prolonged

with a visual warning. A steering wheel

symbol appears in the multifunction display.

not taken hold of the steering wheel after five

seconds, a warning tone also sounds to

remind you to take control of the vehicle.

DISTRONIC PLUS Steering Assist is then

switched to passive. DISTRONIC PLUS

longer assists you by performing steering

interventions if:

R

you actively change lanes

R

you switch on the turn signal
