ț Comply with the warnings
(
୴ page 357) and rules for off-road
driving ( ୴ page 358).
ț Driving on embankments, slopes and
other steep inclines should only be
done straight up or downhill, i.e. in the
line of gravity. Maximum vehicle climb-
ing ability is a 100% grade which is
equivalent to a slope angle of
45 degrees. Keep in mind that the
climbing ability of the vehicle depends
on terrain conditions.
ț Shift automatic transmission to
position 1 (
୴ page 200).
ț Drive slowly.
ț Avoid excessive engine speeds – drive
with moderate engine speeds
(max. 3 000 rpm).
ț Utilize the engine’s braking power
when descending a slope, observe the
engine speed (do not overrev the en-
gine). Apply the service brake as need-
ed.
ț Check the brakes after a lengthy down-
grade drive.
