AI-SHIFT
■
The AI-SHIFT automatically selects the suitable gear according to driver perfor-
mance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift
lever to the M position cancels the function.)
CAUTION
When driving on slippery road surfaces
■
Be careful of downshifting and sudden acceleration, as this could result in the vehi-
cle skidding to the side or spinning.
