Starting and operating

. When a temporary spare tire is
installed
. When your vehicle is towed
. When the vehicle is stopped
with the manual mode selected

NOTE
. A higher initial LSD torque setting
gives the vehicle greater traction when
driving straight ahead but makes cornering more difficult. Remember this
when adjusting the initial LSD torque.
In general, higher initial LSD torque
settings assist driving on slippery
roads and lower settings for non-slippery roads. When the vehicle is stuck
in snow or mud, setting the initial LSD
torque to the maximum will help to free
the vehicle.
. The setting of the initial LSD torque
will remain even when the auto mode is
selected or the ignition switch is turned
to the “OFF” position. However, the
initial LSD torque will be minimized
when the battery is disconnected and
reconnected.
. During cornering or when making
turns (especially when going into the
garage), the rotational difference between the front and rear wheels may

cause a braking effect accompanied by
vibration and noise. This does not
indicate a problem. The phenomenon
will disappear when setting the initial
LSD torque to the minimum.
In the auto mode, it controls the initial
LSD torque automatically. While in the
auto mode, this phenomenon sometimes occurs depending on the driving
condition, however, it does not indicate
a problem.
. Use the center differential indicator
light only as a rough indication of the
initial LSD torque.
. If you operate the center differential
control switch while quickly accelerating or turning a tight corner, you may
feel slight shocks. This is due to
differential action by the center differential and does not indicate a problem.

& Temporary release
When the driver stops the vehicle and
pulls the parking brake lever after manually setting the initial LSD torque, the LSD
torque is temporarily minimized. However
the indicator on the combination meter
continues to show the driver’s selected
initial LSD torque. When the driver releases the parking brake lever, the initial
LSD torque set by the driver is restored.

Automatic transmission
The automatic transmission is electronically controlled and provides 4 forward
speeds and 1 reverse speed. Also, it has a
manual mode and a SPORT mode.

WARNING
Do not shift from the “P” or “N”
position into the “D” or “R” position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.

CAUTION
. Shift into the “P” or “R” position
only after the vehicle is completely stopped. Shifting while the
vehicle is moving may cause
damage to the transmission.
. Do not race the engine for more
than 5 seconds in any position
except the “N” or “P” position
when the brake is set or when
chocks are used in the wheels.
This may cause the automatic
transmission fluid to overheat.
. Avoid shifting from one of the
forward driving positions into the
