2006 Lexus GS430 Scheduled Maintenance Guide / LEXUS 2006 GS430/GS300 FROM JAN. 2005 PROD. OWNER'S MANUAL (OM30649U)

KEYS AND DOORS
36If a wrong key is used, the key cylinder rotates freely to isolate
inside
mechanism. So, door locking is protected from thieves.
The windows and moon roof can be opened and closed from
outside the vehicle using a mechanical key. For details, see
“Power window switches” on page 57 and “Moon roof” on page
132.

Push in the lock button to lock and unlock the door.
The front doors can be opened by pulling the inside handles
even if the lock buttons are in the locked position.

KEYS AND DOORS

Closing the door with the lock button pushed in will also lock
the door. If the electronic key is left in the vehicle, locking
cannot be done.
If the vehicle is subjected to a severe frontal, rear or side
impact with the engine switch in “IG
−ON” mode, all the doors
will unlock automatically after a few seconds.
CAUTION
Before driving, make sure the doors are closed and
locked, especially when small children are in the
vehicle. Along with the proper use of seat belts, locking
the doors helps prevent the driver and passengers from
being thrown out from the vehicle during an accident.
It also helps prevent the doors from being opened
unintentionally.

lights come on. To turn off the lights, push the power door lock
switch on the lock side. (For details, see “Outer foot lights” on
