I have no security light 2006 Buick lacrosse cxl 3.8l

Hi,

Here’s the owner manual for the vehicle.

Go through the manual in the following sequence to check if it has a content theft-deterrent alarm system, what occurs when it is activated and if it does have the system, how to enable it if it has been disabled.

The page numbering is easier to follow if you type the page number in the box at the top left of document header bar next to “of 438” and press the Enter key.

p167 of 438 shows the Security light indicator in the instrument panel and I assume that this is the one you meant or did you mean the other one - see next step?

p.92 of 438 shows the security light on top of the dashboard and explains what occurs if it is activated - see under Content Theft-Deterrent

p.195 of 438 show how to customize the Content theft setting so that it can be enabled or disabled - see DIC Vehicle Personalization & Entering the Personal Program Menu

p.199 of 438 Content theft is the section which just shows the options for the setting so that you can enable and disable the security light feature if it is available in your vehicle.
