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.

●The AI-SHIFT automatically selects the suitab le gear according to driver performance
and driving conditions.

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

: If equipped
The ASC system is an electronic sound system that generates driving sound,
conveying the kinetic situations of the vehicle’s acceleration and deceleration
to the driver through the speakers behi nd the instrument panel. The vehicle’s
response to the driver’s acceleration behavior and shift operations are also
conveyed in sound. When sport mode is selected, the sound conveyed to the
driver will be louder.

■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.
