■Shift position uses
*1: To improve fuel consumption and reduce noises, set the shift lever in the D
position for normal driving.
*2: Selecting shift ranges using S mode re stricts the upper limit of the possible
gear ranges, controls engine brakin g forces, and prevents unnecessary
upshifting.
■ Selecting a driving mode
The following patterns can be selec ted to suit current driving and
operating conditions.
Power mode
For powerful acceleration
and driving in mountainous
regions.
Normal mode
Snow mode
For accelerating and driving
on slippery road surfaces,
such as on snow.

vehicle speed. However, the initial shift range may be set to 3 or 2 if the
AI-SHIFT has operated while the shift lever was in the D position.
( P. 100)
■ Shift ranges and their functions
A lower shift range will provide greater engine braking forces than a higher shift
range.

when the shift lever or shift paddle switch is operated. (The warning buzzer will
sound twice.)
■When driving with the cruise control syst em 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. 1 2 6 , 1 2 9 )
■SNOW mode automatic deactivation
SNOW mode is automatically deactivated if the engine switch is turned to ACC or
IG-ON mode after driving in SNOW mode.
■If the shift lever cannot be shifted from P
 P. 3 6 1
■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.)

The AI-SHIFT automatically sh ifts the gear to the optimal position according to the
driver performance and driving conditions.
The AI-SHIFT automatically operates when th e shift lever is in the D position. (Shift-
ing the shift lever to the S position cancels the function.)
