how many times do you have to push it. is it once to lock and twice to unlock.

Ah. The small pleasures in life. :tup:

Lock your car. Push the gas door and hit the unlock. The gas door will then pop open.

You are lucky old folks stick together, and my arms are still long enough to read and look this up for you.

Switching procedure:
To switch the hazard indicator and horn (chime)
operation, push the LOCK *1 and UN-

simultaneously for more than 2 seconds.

the horn chirps once.
