The driver

’s control center differential has

an auto mode and a manual mode. In the
auto mode, the system automatically
adjusts the initial LSD torque. In the
manual mode, you can change to the
desired mode manually by using the
center differential control switch.

NOTE

If you rapidly depress and release the
accelerator pedal while driving at low
speed, you may hear a knocking sound
from the vicinity of the center differen-

tial and rear differential. This sound
occurs because of the structure of the
center differential. It does not indicate a
problem.

& To change mode of driver’s

control center differential

Press the

“AUTO-MANU” switch on the

center console to switch from auto mode
to manual mode or vice versa. When you
select the auto mode, the

“AUTO” indica-

tor light illuminates. When you select the
manual mode, the

“AUTO” indicator light

turns off.

& Auto mode

In the auto mode, the system estimates
the driving and road conditions using
signals from the wheel speed sensor,
throttle position sensor, steering angle
sensor and brake switch, etc. According
to the result, it electronically and auto-
matically controls the degree of limitation
of the differential action (LSD torque) to
optimize the differential action of the
center differential. When the ignition
switch is turned ON, the

“AUTO” indicator

light on the combination meter illuminates.
