Locking differential (for (Diesel) 2.5 VGT) (if equipped)
A locking differential, if equipped, is for the rear wheel differential only. The features of this locking differential are described below:
Just as with a conventional differential, the wheel on one side is allowed to turn at a different speed from the wheel on the other side when the vehicle is cornering. The difference between the locking differential and a conventional differential is that if the wheel on one side of the vehicle loses traction, a greater amount of torque is applied to the rear wheel on the other side to improve traction.

In a stationary position, the LD (Locking Differential) will operate when the difference of the revolution speed between the rear right wheel and the rear left wheel occurs.
The following procedures can be used to confirm that the locking differential is functioning properly:
-
Position the vehicle so that one wheel is on a dry paved surface and the other on ice, snow, mud, etc. Drive the vehicle, and observe the operation of the locking differential. The vehicle should not become stuck if the differential is functioning properly.
-
Depress the accelerator pedal gradually, and then when traction is good, depress it forcefully. If the vehicle accelerates well, the differential is functioning properly.

Usually a locking differential will operate and release automatically but occasionally it may not release automatically.
At this time you will feel the tyre is dragged when you are driving or cornering. You can release it manually by slightly turning the steering wheel right and left whilst the vehicle is moving slowly.

-
Never start the engine with the gearshift lever placed in the forward or reverse whilst one of the rear wheels is jacked up and the other in contact with the ground; doing so may cause the vehicle to jump forward.
-
If one of the rear wheels begins to spin in mud, snow, etc., the vehicle can sometimes be driven out by depressing the accelerator pedal further; however, avoid running the engine continuously at high rpm because doing so could damage the locking differential.
