designat eddistanc efrom thevehicle infron t.
You must select alower gearingood timeon
long andsteep downhill gradients,especially if
the vehicle isladen. Bydoing so,you willmake
use ofthe brakin geffec tof the engin e.This
relieves theload onthe brake system andpre-
vent sthe brakes fromoverheat ingand wear-

If Ac tive Distance Assist DISTRONIC detects
that thereis arisk ofacollision withthevehi-
cle infron t,you willbewarned visuallyand
audibly. Active Distance Assist DISTRONIC
cann otpreven ta collision withoutyourinter-
vent ion. Anintermit tentwarning tonewill then
