4-2. Driving procedures
Automatic transmission (gasoline vehicles)
While the “START STOP ENGINE” switch is in IGNITION ON
mode, move the shift lever with the brake pedal depressed.
When shifting the shift lever between P and D, make sure that the vehicle is
completely stopped.
*1: Shifting the shift lever to D allows the system to select a gear suitable for the driv-ing conditions.
Setting the shift lever to D is recommended for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the possible gearranges, controls engine braking force, and prevents unnecessary upshifting.

4-2. Driving procedures
■S mode
●When the shift range is S4 or lower, holding the shift lever toward “+” sets the shift
range to S6.
●To prevent excessive engine speed, a function was adopted that automatically
selects a higher shift range before the engine speed becomes too high.
●To protect the automatic transmission, a function is adopted that automatically
selects a higher shift range when the fluid temperature is high.
■When driving with cruise control activated
Even when performing the following actions with the intent of enabling engine brak-
ing, the engine brake will not operate in the S mode, even when downshifting to 5 or
4. (→P. 2 5 4 )
■Downshifting restrictions warning buzzer
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 is operated. (A buzzer will sound twice.)
■If the S 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 vehi-
cle inspected by your Lexus dealer immediately.
(In this situation, the transmission will operate in the same manner as when the shift
lever is in D.)
■If the shift lever cannot be shifted from P
→P. 6 76
■AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver performance
and driving conditions.
AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift lever
to S cancels the function.)
