■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.
■If the shift lever cannot be shifted from P
First, check whether the brak e 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: The G AI-SHIFT is automa tically changed to a suitable gear step
while running in sport mode according to the driving operations and running condi-
tions.
The G AI-SHIFT automatically operates when the drive mode select switch is set to
sport mode with the shift leve r in the D position. (The function will be canceled, if the
drive mode is select switch is set to normal mode or shift lever is put in the M position.)

WARNING
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the vehicle
skidding to the side or spinning.
■To prevent an accident wh en releasing the shift lock
Before pressing the shift lock override butto n, make sure to set the parking brake and
depress the brake pedal.

1904-3. Operating the lights and wipers
IS350/300/200t_U (OM53D76U)
■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically whenever the engine is started with the headlight
switch off (for Canada) or in the or “AUTO” position and the parking brake
released. (Illuminate brighter than the par king lights.) Daytime running 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.
■Headlight control sensor
■Automatic light off system
When the light switch is in , or : The headlights and tail lights turn off 30
seconds after the engine switch is turned to ACCESSORY mode or turned off and a
door is opened and all of the doors and trun k are closed. (The lights turn off immediately
if on the key is pressed twic e after all the doors are closed.)
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn the
light switch off once and then back to or .
If any of the doors or trunk lid is left open , the lights automatically turn off after 20 min-
utes.
■Automatic headlight leveling system
The level of the headlights is automatically adjusted accordi ng 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. 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.

2024-3. Operating the lights and wipers
IS350/300/200t_U (OM53D76U)
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper is turned to AUTO mode wh ile the engine switch is in IGNITION ON
mode, the wipers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F (-30°C)
or lower, automatic operation may not occur. In this case, operate the wipers in any
mode other than AUTO mode.
■When the windshield wipers are in tempor ary operation (vehicles with rain-sensing
windshield wipers)
AUTO mode cannot be activa ted even if is pressed.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is adopted. It may not oper-
ate properly when sunlight from the rising or
setting of the sun inte rmittently strikes the
windshield, or if bugs etc. are present on the
windshield.
WARNING
■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibratio n in AUTO mode. Take care that your fingers or anything
else do not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fl uid until the windshield becomes warm. The
fluid may freeze on the windshield and cause lo w visibility. This may lead to an accident,
resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be cau sed if the lever is pulled toward you and
held continually.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
