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 80% grade which is equiv-
alent to a slope angle of approximately
38 degrees. Keep in mind that the
climbing ability of the vehicle depends
on terrain conditions.
Select gear range 2 or 1 on the auto-
matic transmission ( page 154).
Drive slowly.
Utilize the engine's braking power
when descending a slope, observe the
engine speed (do not overrev the en-
gine). Apply the brake as needed.
Check the brakes after a lengthy down-
grade drive.
Traction in steep terrain
Be easy on the accelerator and watch for
continuous wheel traction when driving in
steep terrain.

The 4-ETS helps greatly when starting
out on a steep incline when the front
wheels have then the tendency to slip
due to the weight shifting away the
front axle.The 4-ETS recognizes the sit-
uation and limits the torque for the
front wheels by braking them. Simulta-
neously the torque for the rear wheels
is provided.
