Differential consists of differential case, planetary gear shaft, 2 planetary gears, 2 side gears, and composite thrust washers. The automotive differential is a mechanism that enables the left and right drive wheels to rotate at different speeds. Its function is to allow the left and right wheels to roll at different speeds when the vehicle is turning or driving on uneven roads, ensuring that both drive wheels perform pure rolling motion. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive systems, to drive all four wheels, they must be connected. If all four wheels are mechanically connected together, the vehicle cannot rotate at the same speed when driving on curves. To maintain basic speed consistency during curve driving, a center differential is required to adjust the speed difference between the front and rear wheels.

How to fold down the rear seats of the Yaris L?

Before folding down the rear seats, move the front seats forward to ensure there is enough space for the rear seats to be folded. Close the center armrest in the rear seats to avoid friction, and retract the seatbelt buckle of the middle rear seat. It is best to have the headrest in the lowest position. There is a thin strap on the side of the rear seat—pulling it allows you to adjust the backrest angle forward or backward. Fold down the rear seats.

Formula: Depreciation is calculated based on the mileage driven, with the depreciation amount equaling the original value multiplied by (mileage already driven divided by the estimated total mileage). Double Declining Balance Method Calculation Formula: The depreciation percentage equals 2 divided by the estimated useful life, and the annual depreciation amount equals the value at the beginning of the year. Sum-of-the-Years'-Digits Method Formula: The depreciation amount equals the original value multiplied by (remaining useful life divided by the sum of the useful life years).
