Operation
Driving instructions
Tires
Check the tread depth and maintain
specified tire inflation pressure
(a placard with the recommended tire
inflation pressures is located on the
driver's door B-pillar).
Check tires for possible damage and
remove foreign objects.
Replace missing valve caps.
Rims
Dented or bent rims can cause tire in-
flation pressure loss and damage the
tire beads. For this reason, check and,
if necessary, change rims before driv-
ing off-road.
Vehicle tool kit
Check if the vehicle jack is functional.
In all cases take the vehicle tool kit, a
strong tow rope, a shovel and a small
plank (to put under the vehicle jack on
sandy soil) with you.

Switch to Off-road driving program
( page 248) before starting to drive
up or down steep inclines.
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.
Do not drive along the side of a slope
(danger of vehicle rollover). If in doing
so the vehicle begins to show a tenden-
cy to roll, immediately steer into a line
of gravity (straight up or downhill).
