The ML 350 4MATIC model has a departure angle of 23°.

This
style ofdriving prevent s:
R the vehicle fromlifting offthe ground onthe
brow ofahill
R the vehicle fromtraveling tooquickly down
the other side
Driving downhill R
Drive slowly.
R Do not drive atan angle down steep
inclines. Steer into theline offall and drive
with thefron twheels aligned straight.
Otherwise, thevehicle couldslipsidewa ys,
tip and rollover.
R Before tackling steepdownhill gradients,
select shiftrange 1.
R Act ivate DSR. Ifthis isnot sufficient, brake
gently. Whendoingso,make surethatthe
vehicle isfacing inthe direction ofthe line
of fall.
R Check thatthebrakes areworking normally
after along downhill stretch. i
