How to Turn Off the Button Lights on an Older Model Buick LaCrosse?

[RyanAnn]

Turn off the engine and close all BI doors. Insert the ignition key and turn it to the RUN position. Press and hold the electric door lock switch. Release the electric door lock switch. These operations must be completed within 10 seconds, with no more than a 10-second interval between actions.

Last month, while driving my old Buick LaCrosse on a nighttime mountain road trip, I noticed the backlighting of the buttons on the center console was glaringly bright and somewhat distracting. After fumbling around for a while, I finally found the brightness adjustment knob near the instrument panel, usually marked with a small sun icon. A gentle turn of this knob allowed me to dim or even turn off the button backlights, simultaneously reducing the brightness of the instrument panel backlighting as well. Older car models don’t have as many electronic settings—this physical knob controls all the interior lighting. After adjusting it, driving became much more comfortable, though I had to be careful not to set it too dim, as operating the buttons in the dark could become difficult. I also tested it a few times before setting off to ensure its reliability, since nighttime driving safety comes first—no distractions allowed.

Having driven the old LaCrosse for over a decade, I'm familiar with every button in the car. Turning off the button lights is quite simple: after getting in, locate the illumination control knob - that round dial either below the left side of the steering wheel or on the center console. Just rotate it to dim all interior lights, including the button backlights. I remember when I first bought it, the lights were too glaring, so I turned them down to the minimum - made nighttime driving much more focused. That's how the older models were designed - no separate menu for button lights, adjusting brightness handles everything at once. After a few practices, it becomes second nature. I'd recommend doing this while parked rather than fiddling with it while driving to prevent accidents.

After playing with cars for a long time, I found that the button lights on the old LaCrosse are actually integrated with the overall lighting system. After getting in the car, just locate the brightness knob in the instrument panel area and give it a gentle turn to dim or turn off the button lights, saving power and reducing distractions. This is basic circuit design—when the brightness is turned down, the lights will naturally go out. It's a simple and safe operation that you can do yourself without needing to visit a repair shop.

When driving an older LaCrosse at night, the overly bright button lights can be distracting, so I prefer adjusting them to a lower brightness for safety. I usually use the dashboard brightness control knob: start the car first, then rotate the knob to the dimmest setting to turn off the lights. The operation is quick and doesn't interfere with driving. One advantage of older models is that the brightness doesn't automatically reset, so once set, the dim lighting stays throughout the trip, preventing eye strain. If you turn them off completely, remember to leave a little glow for easier button location, avoiding dangerous blind operation.

The other day, I was test-driving my old LaCrosse in the garage, and the button lights were glowing like little nightlights, which was quite amusing. I recalled the method mentioned in the user manual: simply turn the brightness control knob next to the instrument panel, and with a gentle twist, the lights dimmed. Turning it all the way down basically turned off the button lights—pretty straightforward for an older model, no need to dive into any electronic menus. After the adjustment, I was delighted; with the lights off, the interior felt cleaner, making nighttime driving more relaxing. I even recommended it to my friends, and they all said it worked great, especially during road trips to avoid distracting from the beautiful scenery.
