Selection Mode

The TOD system has 2 selectable mode, 4H and 4L.
4H is the normal operating mode when drive of which
gear ratio is 1:1 and 4L mode distributes power to front
and rear wheels 50:50 of which gear ratio is 2.48:1.

4L Mode

When selecting 4L mode, EMC is locked to apply maximum
torque into front and rear propeller shafts (when the wheel
speed is more than 87Hz). Shift motor rotates also 4L posi-
tion by rotation of cam thus propeller shaft torque changes
from 1:1 to 2.48:1 by planetary gear set.

Releasing the 4L Mode

When selecting 4H mode, 4L drive mode is released and 4H
mode is resumed.

• “4H” switch: Self-return type

• “4L” switch: Push lock type

 [Notice]

To make the mode shift easier, stop the vehicle, depress the brake pedal, select the mode switch, and move the selector
lever with the sequence of [N-P-N].
