Four-wheel drive system
H2 (high speed position, two-
wheel drive)
Use this for normal driving on dry
hard-surfaced roads. This position
gives greater economy, quietest
ride and least wear.
H4 (high speed position, four-
wheel drive)
Use this for driving only on tracks
that permit the tires slide, like off-
road, icy or snow-covered roads.
This position provides greater trac-
tion than two-wheel drive.
The four-wheel drive indicator
light comes on
L4 (low speed position, four-
wheel drive)
Use this for maximum power and traction. Use L4 for climbing or descend-
ing steep hills, off-road driving, and hard pulling in sand, mud or deep
snow.
The four-wheel drive and low speed four-wheel drive indicator lights
come on
The A.D.D. can be engaged or disengaged by the shifting operations

■Four-wheel drive usage frequency (vehicles with A.D.D.)
You should drive in four-wheel drive for at least 16 km (10 miles) each month.
This will assure that the front drive components are lubricated.
■ Shifting between H2 and H4
If you have trouble shifting in cold w eather, reduce your speed or stop the
vehicle and reshift.
■ Shifting to L4 (vehicles with VSC)
VSC is automatically turned off.
■ When driving on dry paved surface roads and expressway
Use H2 position. If the vehicle is driven in H4 or L4 position for a long time, a
warning buzzer sounds, and the four-wheel drive indicator light flashes rap-
idly or a warning message is shown on the multi-information display. If the
warning message is shown on the multi-information display, follow the mes-
sage.
WARNING
■ While driving
● Never turn 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.
