AI-SHIFT
The AI-SHIFT automatically selects the suitable gear according to driver perfor-

The AI-SHIFT automatically operates when the shift lever is in D. (Shifting the
shift lever to the M position cancels the function.)

position, the current gear position is dis-
played on the multi-information display.

When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the
vehicle skidding to the side or spinning.
