2-1. Driving procedures

If does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional, immediately.
(In this situation, the vehicle will operate as if the shift lever is in D.)

AI-SHIFT
The AI-SHIFT automatically shifts the gear to the suitable position accord-
ing to the driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D posi-
tion. However, operating the "-" paddle shift switch will restrict the func-
tion's operation. (Shifting the shift lever to the S 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.
