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 m symbol.
If the off-road gear is disengaged and the on-road
gear is engaged again, the display goes off.
Even if all engagement conditions are met, chang‐
ing gear can take up to three seconds for vehicles
with a manual transmission. When off-road gear
is engaged, the shift range for upshifts is auto‐
matically limited for vehicles with an automated
manual transmission. If the interaxle differental
lock is engaged and ABS is switched on during
off-road driving, there can be interruptions in the
tractive power in switch positions 1 or 2.
Vehicles with automatic manual transmission:

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:
