General notes DIS
TRONIC PLUSregulates thespeed and
automatically helpsyoumaintain the

brakes automatically inorder toavoid
exceeding thesetspeed.
On long andsteep downhill gradients,
especially ifthe vehicle isladen ortowing a
trailer, youmust select shiftrange 1,2or 3

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
