Do not disconnect the battery if the vehicle has an anti-theft-coded radio. If equipped with an air bag, avoid discon-
necting the battery if possible.
IMPORTANT! Many airbag systems will display a diagnostic code through their warning light after they lose
power. Disconnecting the battery requires this code to be erased, a procedure that can require a trip to the
dealer.
Before beginning the installation:
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.
