The current gear is displayed on the multi-information display. (P. 1 2 1 )
■Downshifting restrictions warning buzzer (in the S mode)
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever or shift paddle switch is operated. (The warning buzzer will
sound twice.)
■When driving with the cruise control system or dynamic radar cruise control sys-
tem
The engine brake will not operate in the S mode, even when downshifting to 5 or 4.
(P. 130, 133)
■SNOW mode automatic deactivation
SNOW mode is automatically deactivated if the engine switch is turned off after
driving in SNOW mode.
■If the shift lever cannot be shifted from P
P. 3 6 7
■If the indicator 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 your Lexus dealer 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 optimal position according to the
driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D position. (Shift-
ing the shift lever to the S position cancels the function.)
