■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNITION ON
mode (the engine is not running) for more than an hour with the shift lever in P, the engine
switch will automatically turn off. However, this function cannot entirely prevent battery
discharge. Do not leave the vehicle with the engine switch in ACCESSORY or IGNI-
TION ON mode for long periods of ti me when the engine is not running.

■Steering lock
After turning the engine switch off and opening and closing the doors, the steering wheel
will be locked due to the stee ring lock function. Operating the engine switch again auto-
matically cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from over heating, operation of the motor may be sus-
pended if the engine is turned on and off repeat edly in a short period of time. In this case,
refrain from operating the engine switch. After about 10 seconds, the steering lock
motor will resume functioning.

■Operation of the engine switch
●When operating the engine switch, one short, firm press is enough. If the switch is
pressed improperly, the engine may not start or the engine switch mode may not
change. It is not necessary to press and hold the switch.
●If attempting to restart the engine immediately after turning the engine switch off, the
engine may not start in some cases. After tu rning the engine switch off, please wait a
few seconds before re starting the engine.

■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accelerator
pedal while starting the engine under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. Activation of the steering lock in this cir-
cumstance may lead to an accident, re sulting in death or serious injury.
■Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle, press and hold
the engine switch for more than 2 seconds, or press it briefly 3 times or more in succes-
sion. ( P. 5 2 3 )
However, do not touch the engine switch while driving except in an emergency. Turning
the engine off while driving will not cause lo ss of steering or braking control, but the
power assist to these systems will be lost. Th is will make it more difficult to steer and
brake, so you should pull over and stop the vehicle as soon as it is safe to do so.

NOTICE
■To prevent battery discharge
●Do not leave the engine switch in AC CESSORY or IGNITION ON mode for long
periods of time without the engine running.
●RC350: If “ACCESSORY” or “IGNITION ON” is displayed on the meters while the
engine is not running, the engine switch is not off. Exit the vehicle after turning the
engine switch off.
●RC F: If the analog speedometer is illum inated and the engine is not running, the
engine switch is not off. Exit the vehicle after turning the engine switch off.
However, if the welcome illumination is operating, the analog speedometer will be
illuminated even though the engine sw itch is off. (Welcome illumination: P. 1 0 1 )
●Do not stop the engine when the shift lever is in a position other than P. If the engine is
stopped in another shift lever position, the engine switch will not be turned off but
instead be turned to ACCESSORY mode. If the vehicle is left in ACCESSORY
mode, battery discharge may occur.
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to start or stalls frequently, have your vehicle checked
by your Lexus dealer immediately.
■Symptoms indicating a malfun ction with the engine switch
If the engine switch seems to be operating somewhat differently than usual, such as the
switch sticking slightly, there may be a malf unction. Contact your Lexus dealer immedi-
ately.

To drive using temporary shift range selection, operate the “-” or “+” paddle shift
switch.
When the “-” paddle shift switch is operated, the shift range will be downshifted
to a range that enables engine braking forc e that is suitable to driving conditions.
When the “+” paddle shift switch is operated, the shift range will be one gear
higher than the gear in use during normal D position driving.
Changing the shift range allows restriction of the highest gear, preventing unnec-
essary upshifting and enabling the level of engine braking force to be selected.
Upshifting
Downshifting
8-speed models: Th e selected shift
range, from D1 to D8, will be displayed
in the meter.
6-speed models: The selected shift
range, from D1 to D6, will be displayed
in the meter.
To return to normal D position driving,
the “+” paddle shift switch must be held
down for a period of time.
■Shift ranges and their functions
A lower shift range will provide greater engi ne braking forces than a higher shift
range.

To enter M mode, shift the shift lever to M. Gears can then be selected by oper-
ating the shift lever or paddle shift switches, allowing you to drive in the gear of
your choosing.
Upshifting
Downshifting
The gear changes once every time the
shift lever or paddle shift switch is oper-
ated.
8-speed models: Th e selected gear,
from M1 to M8, will be fixed and dis-
played in the meter.
6-speed models: The selected gear,
from M1 to M6, will be fixed and dis-
played in the meter.
When in the M position, the gear will no t change unless the shift lever or pad-
dle shift switches are operated.
However, even when in the M position, the gears will be automatically
changed in the following situation:
●When vehicle speed drops (downshift only).
●When a gear change is necessary to protect the engine or automatic trans-
mission when the engine coolant temperature or automatic transmission
fluid temperature is low, or other reasons.
In the following situations, the gear will not shift even if the shift lever or paddle
shift switches are operated.
●“1st Gear not available due to slippe ry road surface” is displayed on the
multi-information display.
●The vehicle speed is low (upshift only).

■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.

■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.)

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.
