When driving
■If the automatic transmission fluid temperature warning light comes on
■AI-SHIFT
The AI-SHIFT automatically selects the optimal gear according to driver perfor-
mance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D position. How-
ever, operating the “-” paddle shift switch will restrict the function’s operation. (Shift-
ing the shift lever to the M po sition cancels the function.)
CAUTION
■When driving on slippery road surfaces
Be careful of downshifting and sudden accele ration, as this could result in the vehi-
cle skidding to the side or spinning.
If the automatic transmission fluid tempera-
ture 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 wait-
ing a while, have your vehicle inspected by
your Lexus dealer.
