You should drive in four-wheel drive for at least 10 miles (16 km) each

This will assure that the front-drive components are lubricated.
CAUTION

Caution while driving
●
Never shift the front-wheel drive control switch from H2 to H4 if the wheels
are slipping.
Stop the slipping or spinning before shifting.
●
For normal driving on dry and hard surface roads, use H2 position. Driving
on dry and hard surface roads in H4 or L4 position may cause drive com-
ponent oil leakage, seizure, or other problems resulting in an accident.
Further, it may cause tire wear and increased fuel consumption.
●
Avoid turning suddenly in H4 or L4 position. If you do turn suddenly, the
difference in turning speeds between the front and rear wheels may have
a similar effect to braking, thus making driving difficult.
