The four-wheel drive indicator comes on when H4 or L4 mode is
selected. H2 (high speed position, two-wheel drive)
Use this for normal driving on dry hard-surfaced roads. This po sition gives
greater economy, quietest ride and least wear.
H4 (high speed positi on, 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 tract ion than
two-wheel drive.
L4 (low speed position, four-wheel drive)
Use this for maximum power and traction. Use “L4” for climbing or
descending steep hills, off-road driving, and hard pulling in s and, mud or
