What alarm would my car have

I'm not sure what they would've included on cars delivered to your area.

For North America it's nothing special; it notices if a door is opened without having been disarmed. Also it can be triggered from the remote as a panic button. There's an interface for optional extra sensors, and that's about it.

You can probably get more info from Toyota's website- again not sure how they do it for your area but we can get PDFs of the manuals that give all the details.
