Tip on driving
When the center differential lock is fully engaged,
there is no longer any speed difference between
the front and rear axles. If, for example, both
wheels at the front axle lose traction on an icy
road or soft surface, the rigidly linked drive wheels
will permit the vehicle to continue moving never-
theless.

Low Range
Tip on driving
When the rear differential lock is fully engaged,
there is no longer any speed difference between
the two rear wheels. If, for example, one drive
wheel at the rear axle loses traction on an icy road
or soft surface, the stiff through-drive function will
permit the vehicle to continue moving neverthe-
less.
