. When the vehicle is stopped

lected

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 memo ry 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.
