KEYS AND DOORS
Locking/Unlocking the doors
When you push the "LOCK" button on the key briefly, all
the doors can be locked from outside the vehicle.
At this time, you can hear one beep and turn signal lights flash
once.* However, when you push the "LOCK" button with any
door not closed securely, the buzzer sounds for 10 seconds.**
To stop the buzzer, close all the doors securely or push the
"UNLOCK" button. If the key is in the ignition switch, locking
cannot be done.
NOTE: *The turn signal lights can be set not to flash. **The
buzzer can be set not to sound if a door is not closed
securely. Ask your Lexus dealer for details.
If outer foot lights are illuminated, you can turn off the lights by
pushing the "LOCK" button on the key. (For details, see "Outer
foot lights" on page 125.)
NOTICE
Do not push the "LOCK" button any longer than 2 to 3
seconds. Pushing the button longer activates an alarm.
For details, see page 16.

When you push the "UNLOCK" button, the driver's door
is unlocked and outer foot lights come on. Pushing the
"UNLOCK" button once again within 3 seconds will
unlock all other doors.*

Ask your Lexus dealer for details.
At this time, two beeps sound and turn signal lights flash twice.*
Together with the activation of unlocking, the interior light
comes on for 15 seconds if the interior light switch is in "DOOR"
position.** However, this function does not work when the
ignition switch is in the "ACC" or "ON" position. For further
information, see "Interior lights" on page 71.
For outer foot lights, see "Outer foot lights" on page 125.
You have 30 seconds to open a door after using the wireless
remote unlock feature.*** If a door is not opened by then, all
the doors will be automatically locked again.
NOTE: *The turn signal lights can be set not to flash. **The
interior light can be set not to come on or the duration of
lighting can be changed. ***The time before automatic
re–locking can be changed. Ask your Lexus dealer for
details.
Even if the "LOCK" or "UNLOCK" button is kept pressed in, the
locking or unlocking operation is not repeated. Release the
button and then push again.
