2-1. Driving procedures
■When the “-” shift paddle switch is operated in the D position
When the “-” shift paddle switch is operated in the D position, a shift range will be
automatically selected. The highest gear of the first shift range will be one gear
lower than the gear in use during normal D position driving.
■Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●When range 6 is selected and the accelerator pedal is depressed
●If the accelerator pedal is depressed for more than a certain period of time
■To protect automatic transmission
A function is adopted that automatically se lects a higher shift range when the fluid
temperature is high.
■Gear position disp lay when driving
The current gear is displayed on the multi-information display. ( P. 1 6 5 )
■Downshifting restrictions warning buzzer
To help ensure safety and driving perfor mance, downshifting operation may some-
times be restricted. In some circumstance s, 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
Engine braking will not occur during shif t range selection in the D position or S
mode, even when downshifting to range 5 or 4. ( P. 181)

When driving
■If 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 suitable position according to the
driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D position. How-
ever, operating the “-” shift paddle switch will restrict the function’s operation. (Shift-
ing the shift lever to the S position 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.

■Gear position display
Indicates the current gear , and the range of gears
that is available when the shift lever is in the D or S
position. The gear range is shown by the number of
dots ( ) and the current gear is shown as a number.
The transmission automatically selects the gears
within the driver selected gear range.
In the illustration to the left , a range of 6 available gears
(1 through 6) has been selected by the driver. (The shift
lever is in the D or S position with 6 ranges enabled.) It is
possible for the transmission to automatically select
between all 6 of the gears. In this case, the transmission
has selected third gear.
■System check display
After switching the “ENGINE START ST OP” switch to IGNITION ON mode,
“CHECK” is displayed while system operation is checked. When the system check
is complete, “COMPLETED” is displayed before returning to the normal screen.
■Outside temperature display
In the following situations, the correct outside temperature may not be displayed, or
the display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 12 mph [20 km/h])
●When the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)
