on paved roads. This vehicle level is intended
for clearing impracticable situations at low
speed exclusively. The vehicle has a very high
center of gravity in off-road level 3. This
increases the overturning hazard.
R Select off-road level 3 exclusively for
clearing impracticable situations at low
speed.
R Adapt your driving style to the modified
conditions.
R Do not exceed a speed of 12 mph
(20 km/h).
R Avoid extreme, quick steering movements.

characteristics are modified.
You should therefore drive in off-road level 3
with particular caution as it could otherwise
lead to an accident and/or serious injury to
you or others.

( 20 km/h ) message appears in the
multifunction display. You also hear a
warning. The vehicle is lowered.

appropriate for road conditions. Otherwise,
