■ Please read this entire installation guide before beginning the installation. The installation of this remote
start system requires interfacing with many of the vehicle’s systems. Many new vehicles use low-voltage or
multiplexed systems that can be damaged by low resistance testing devices, such as test lights and logic
probes (computer safe test lights). Test all circuits with a high quality digital multi-meter before making con-
nections.
■ Do not disconnect the battery if the vehicle has an anti-theft-coded radio. If equipped with an air bag, avoid
disconnecting the battery if possible. Many airbag systems will display a diagnostic code through their
warning lights after they lose power. Disconnecting the battery requires this code to be erased, which can
require a trip to the dealer.
■ Check with the customer on status LED location.
■ Remove the domelight fuse. This prevents accidentally draining the battery.
■ Roll down a window to avoid being locked out of the car.
■ Test all functions. The “Using Your System” section of the Owner's Guide is very helpful when testing.
■ When testing, don’t forget that this system is equipped with Nuisance Prevention Circuitry™(NPC™). NPC can
bypass trigger zones, making them appear to stop working. See the Nuisance Prevention Circuitry section.
■ Review and complete the Safety Check section of this guide prior to the vehicle reassembly.
