NOTE
. A higher initial LSD torque setting
gives the vehicle greater traction when
driving straight ahead but makes cor-
nering 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-slip-
pery roads. If you become stuck in
snow or mud, turning the center differ-
ential control dial to the frontmost
position will help move the vehicle
out. (The
“LOCK” indicator will come
on at the frontmost position.)
. During cornering or when making
turns (especially when getting into the
garage), the rotational difference be-
tween 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 you turn the center
differential control dial to the rearmost
position (minimum initial LSD torque
position).
In the auto mode, it controls the initial
LSD torque automatically. While in the
auto mode, this phenomenon some-
times 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 dial 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 manu-
ally setting the initial LSD torque, the LSD
torque is temporarily minimized. However
the indicator in the combination meter
continues to show the driver
’s selected
initial LSD torque. When the driver re-
leases the parking brake lever, the initial
LSD torque set by the driver is restored.
Automatic transmission
The automatic transmission is electroni-
cally controlled and provides 4 forward
speeds and 1 reverse speed.
NOTE
. When the engine coolant tempera-
ture is still low, your vehicle
’s auto-
matic transmission will up-shift at high-
er engine speeds than when the cool-
ant temperature is sufficiently high in
order to shorten the warm-up time and
improve driveability. The gearshift tim-
ing will automatically shift to the nor-
mal timing after the engine has warmed
up.
. Immediately after ATF (automatic
transmission fluid) is replaced, you
may feel that the automatic transmis-
sion operation is somewhat unusual.
This results from invalidation of data
the on-board computer has collected
and stored in memory to allow the
transmission to shift at the most appro-
priate times for the current condition of
your vehicle. Optimized shifting will be
restored as the vehicle continues to be
driven for a while.
