■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
●If the accelerator pedal is depressed for more than a certain period of time
●When the shift lever is shifted to a position other than D
■To protect the automatic transmission
If the automatic transmission fluid temperatur e is high, “Transmission Fluid High Temper-
ature” will be displayed on th e multi-information display and the vehicle will go into trans-
mission protection mode automatically. Have the vehicle inspected by your Lexus dealer.
■Downshifting restriction warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the engine switch is turned off after driving in
snow mode.
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control or dynamic radar cruise control
will not be canceled.
●8-speed models: While driving in the D posi tion, downshifting to 7, 6, 5 or 4.
(  P. 229, 233)
●6-speed models: While driving in the D position, downshifting to 5 or 4.
( P. 229, 233)
●When switching the driving mode to sp ort mode while driving in D position.
(  P. 2 7 8 )
■If the shift lever cannot be shifted from P
P. 5 8 9
■AI-SHIFT
●The AI-SHIFT automatically selects the suitab le gear according to driver performance
and driving conditions.
The AI-SHIFT automatically operates when the sh ift lever is in D. (Shifting the shift lever
to the M position cancels the function.)
●8-speed models: G AI-SHIFT automatically se lects a suitable gear for sporty driving
according to driver’s input and driving co nditions. G AI-SHIFT operates automatically
when the shift lever is in D and sport mode is selected for the driving mode. (Selecting
normal mode with the driving mode select sw itch or shifting the shift lever to the M
position cancels this function.)
WA R N I N G
■When driving on slippery road surfaces
Be careful of downshifting and sudden accele ration, as this could result in the vehicle
skidding to the side or spinning.

Louder
Lower
The indicator comes on when the ASC
system is on.
When the dial is turned to the lowest
volume, the ASC system will be turned
off and the indicator will go off.
■The ASC system can be operated when
The driving mode select switch is in normal mode or sport mode. (P. 2 7 8 )
■Temporary cancelation of the ASC system functions
The ASC system may be temporarily cancele d depending on the driving conditions,
such as when the tires slip due to sudden acceleration.
ASC (Active Sound Control) (RC350)
: If equipped
The ASC system is an electronic sound system that generates engine sound,
conveying the kinetic situations of the vehicle’s acceleration and deceleration
to the driver through the speake rs inside the instrument panel.
The vehicle’s response to the driver’s acceleration behavior and shift opera-
tions are also conveyed in sound.
When sport mode is selected, the sound co nveyed to the driver will be louder.

■The ASC system can be operated when
The driving mode select switch is in SPORT S+ mode. (P. 2 7 8 )
ASC (Active Sound Control) (RC F)
: If equipped
The ASC system sonically emphasizes the vehicle’s response to the driver’s
operation of the accelerator pedal and shift lever or paddle shift switches. The
dynamic engine sound enabled by this system helps the driver further enjoy
the feeling of unity with the vehicle, particularly when driving in M mode.

RC350 (vehicles without Adaptive Variable Suspension System)
Normal mode
Provides an optimal balance of fuel economy, quietness, and dynamic perfor-
mance. Suitable for city driving.
Press the switch to change the driving mode to normal mode when Eco drive mode or
sport mode is selected.
Eco drive mode
Helps the driver accelerate in an eco- friendly manner and improve fuel econ-
omy through moderate throttle characteristics and by controlling the opera-
tion of the air conditioning system (heating/cooling).
When not in Eco drive mode, if the driving mode select switch is turned to the left, the
Eco drive mode indicator will come on.
Sport mode
Controls the transmission and engine to provide quick, powerful acceleration.
This mode also changes the steering f eel, making it suitable for when agile
driving response is desired, such as wh en driving on roads with many curves.
When not in sport mode, if the driving mode select switch is turned to the right, the
“SPORT” indicator will comes on.

●When the steering wheel is operated for an extended period of time while the vehicle is
stopped or is moving very slowly
(on vehicles with LDH, DRS is disabled together with VGRS)
●When the steering wheel has been held fully to the left or right
The center position of the steering wheel may change when VGRS is disabled. However,
the position will return to normal after VGRS is reactivated.
■When the battery is disconnected (vehicles with VGRS)
The steering wheel may move fr om its straight forward position, but this will be corrected
automatically when driving. To select expert mode, press
