This PDF is for Monty Owners who have the "CSI-300 Code Alarm System" (MY 2008-2010?)

Since every Monty only came with the Owner's Manual for the Security Alarm, they didn't provide the Installation Manual which has the Programming Guide

With this guide you can finally turn Off the Auto-Arming or Passive Arming Feature, this happens when you leave the car unlocked for 30 Seconds then it will engange so when you open the door the annoying alarm would sound.
Pls. refer to page 22.

Share this to other Monty owners with the same dilemna, since this is one of those annoyances that can be easily fixed...
You can now also customize your alarm and activate the features you want.
