General notes DIS
TRONIC PLUSregulates thespeed and
automatically helpsyoumaintain the
distance tothe vehicle detectedinfront .It
brakes automatically inorder toavoid
exceeding thesetspeed.
On long andsteep downhill gradients,
especially ifthe vehicle isladen ortowing a
trailer, youmust select shiftrange 1,2or 3
in good time. Bydoing so,you willmake use
of the braking effectofthe engine, which
relieves theload onthe brake system and
prevent sthe brakes fromoverheating and
wearing tooquickly.
If aslower-moving vehicleisdetect edinfront ,
DIS TRONIC PLUScauses yourvehicle to
brake andmaintain thepreset distance tothe
vehicle infront .
If there isno vehicle drivinginfront ofyou,
