2-1. Driving procedures n If the automatic transmission fluid temperature warning light comes on If the automatic transmission fluid temperature warning light comes on while driving, make sure you return to normal D position driving and reduce speed by easing off the accelerator pedal. Stop the vehicle in a safe place, shift the shift lever to the P position and let the engine idle until the warning light goes out. When the warning light goes out, the vehicle can be driven again. If the warning light does not go out after waiting a while, have your vehicle inspected by your Lexus dealer. n AI-SHIFT 2 When driving The AI-SHIFT automatically selects the optimal gear according to driver performance and driving conditions. The AI-SHIFT automatically operates when the shift lever is in the D position. However, operating the "-" paddle shift switch will restrict the function's operation. (Shifting the shift lever to the M position cancels the function.) CAUTION n 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. 127
