Differentials
When driving off the road, the
longitudinal differential lock
and the
transversal differential lock
can be
enabled, so the longitudinal and transversal differentials will be locked.
The transfer case will also act as a longitudinal differential lock.
The
differential indication screen
on the main screen shows an overview of the enabled longitudinal
and transversal differential locks.
For more information, see
§ 3.9.2.3. Main screen: Axles screen.
CAUTION!
The longitudinal and transversal differential lock may solely be used off the road
with loose ground, so NOT fo driving on paved roads!
CAUTION!
•
Enable/disable the longitudinal and transversal differential lock may only be
done when the vehicle stands still!
•
If the longitudinal differential lock is enabled, the road may not contain major
irregularities;
•
If the transversal differential lock is enabled, there may be NO steering;
•
Check after disabling the longitudinal and transversal differential lock if all
locked differentials are disabled.
