■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 fo r more than a certain period of time
●When the shift lever is shifted to a position other than D
■To protect the automatic transmission

■Downshifting restriction warning buzzer
To help ensure safety and driving performance, downshif ting operation may sometimes
be restricted. In some circum stances, downshifting may not be possible even when the
shift lever or paddle shif t switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the engine switch is turn ed 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 crui se 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. 245, 249)
●6-speed models: While driving in the D position, downshifting to 5 or 4.

■Shift lock system
The shift lock system is a system to prevent ac cidental operation of the shift lever in start-
ing.
The shift lever can be shifted from P only when the engine switch is in IGNITION ON
mode and the brake pedal is being depressed.

2184-2. Driving procedures
■If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may be a prob-
lem with the shift lock system. Have the vehi cle inspected by your Lexus dealer immedi-
ately.
The following steps may be used as an emergency measure to ensure that the shift lever
can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch to off.
Depress the brake pedal.
■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 selects 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/RC300/
RC200t)
∗: 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 conveyed to the driver will be louder.

brake is released with the he adlight switch off (for Canada ) or in the “AUTO” position.
(Illuminate brighter than the parking lights.) Daytime runnin g lights are not designed for
use at night.
●Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
●Vehicles with LED front turn signal lights: If a turn signal light is in use, the daytime run-
ning light, on the same side, is turned off. For emergency flashers, both are turned off.

The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

2264-3. Operating the lights and wipers
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■Light reminder buzzer
A buzzer sounds when the engine switch is turned off or turned to ACCESSORY mode
and the driver’s door is opened while the lights are turned on.
■Customization
Settings (e.g. light sensor se nsitivity) can be changed.
(Customizable features: →P. 673)
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than ne cessary when the engine is not running.

■The Automatic High Beam can be operated when
The engine switch is in IGNITION ON mode.
■Camera sensor detection information
●High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When oncoming or preceding vehicles are hidden from sight due to repeated curves, road dividers or roadside trees
●High beam may be turned off if an oncoming vehicle that is using fog lights without
using the headlights is detected.
●House lights, street lights, red traffic sign als, and illuminated billboards or signs may
cause the high beam to turn off.
●The following factors may affect the amount of time taken to turn high beam on or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and preceding
vehicles
• The movement and direction of oncoming and preceding vehicles
• When an oncoming or prec eding vehicle only has operational lights on one side
• When an oncoming or preceding vehicle is a two-wheeled vehicle
• The condition of the road (gradient, cu rve, condition of the road surface etc.)
• The number of passengers and amount of luggage
●High beam may be turned on or of f when unexpected by the driver.
●Small vehicles, such as bicycles, may not be detected.
●In the situations below, the system may not be able to correctly detect the surrounding
brightness levels, and may flas h or expose nearby pedestrians to the high beam. There-
fore, you should consider turning the high beams on or off manually rather than relying
on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to th ose of headlights, tail lights or fog lights.
• Vehicles ahead have headlights or tail lights that are either switched off, dirty, chang-
ing color, or have improperly adjusted aim.
• When driving through an area of intermittently changing brightness and darkness.
• When frequently and repeated ly driving ascending/descending roads, or roads with
rough, bumpy or uneven surfaces (such as stone-paved roads, gravel tracks etc.).
• When frequently and repeatedly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or titling, due to a flat tire, a trailer being towed etc.
• The driver believes that the high beam may be causing problems or distress to other
drivers or pedestrians nearby.

2304-3. Operating the lights and wipers
■Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
Turn the engine switch off while the following conditions are met.
• The headlight switch is in or .
• The headlight switch lever is in high beam position.
• Automatic High Beam switch is on.
Turn the engine switch to IGNITION ON mode.
Within 5 seconds after , repeat pulling th e headlight switch lever to the original
position then pushing it to the high beam po sition quickly 9 times, then leave the lever
in high beam position.
Automatic High Beam (head lights) may turn on even the vehicle is stopped.
WARNING
■Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Al ways drive safely, taking care to observe
your surroundings and turning high beam on or off manually if necessary.
