■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

■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

■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.
