Off-road gear button (example)
Engage the off-road gear to increase the power at
the driven axles when driving off-road.
The off-road gear is selected when all engage‐
ment conditions are met. The instrument cluster
then displays the

Notes on hydraulic auxiliary drive
&
WARNING Risk of injury due to acceler‐
ating force during off-road driving
When driving off-road on uneven surfaces,
the force of the vehicle's acceleration affects
your body from all directions.
You could, for example, be thrown from your
seat.
#
Always wear a seat belt when driving
off-road.
The hydraulic auxiliary drive drives the front axle
depending on the shift and drive program selec‐
tion up to a maximum vehicle speed of 25 km/h
according to your needs. This makes it easier to
pull away on uphill gradients and when off-road.
Avoid spinning the rear wheels. If necessary, first
engage the differential lock on the rear axle.
Switch on the hydraulic auxiliary drive only off-
road.
The Stability Control Assist and ASR (anti-slip
control) are deactivated during activation of the
hydraulic auxiliary drive.
The following indicator lamps light up when the
hydraulic auxiliary drive is active:
R
