■ AI-SHIFT
The AI-SHIFT automatically selects the suitable gear according to driver performance
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 vehicle
skidding to the side or spinning.
