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.
N (neutral position)
No power is delivered to the wheels. The vehicle must be stoppe d.
L4 (low speed position, four-wheel drive)
