15 GL8 date adjustment method: Turn on the radio power, locate the RPT button on the panel, press and hold for 3 seconds. When the screen display starts flashing, rotate the knob on the right to adjust the hours, then press the center button of the right knob to select and adjust the minutes. Turn off the radio, and the time and date will be set correctly. The Buick GL8 is a classic top-tier MPV under the Buick brand, with body dimensions of 5256mm in length, 1878mm in width, and 1776mm in height, and a wheelbase of 3088mm. The vehicle is equipped with a 3.0L VVT V6 engine, delivering a maximum horsepower of 178 and a top speed of 168 km/h.

I've been driving a 2015 GL8 for five years, and setting the date is actually quite simple. First, start the vehicle and power it on, then locate the control stalk on the left side of the steering wheel. There's a small button on the stalk head. Press and hold that button until the settings menu appears on the instrument cluster. Use the control stalk to scroll up and down to find the date option. Note that you need to press the button continuously to select the year, month, and day, with each item requiring individual adjustment. After adjusting, remember to save and exit, otherwise you'll have to start over if the power is cut. By the way, the date often resets when the battery is low, requiring you to set it again. It's recommended to keep a digital clock in the car for temporary reference.

Last year, I helped a friend adjust the date on his old GL8. The operation wasn't difficult, but you had to find the right spot. After getting in the car and turning on the power, don't press the brake, just press the ignition button to the ACC position. The key is the wiper control lever behind the steering wheel—the button on the side of the lever is crucial. Click to switch menu items, and when you see the date option, hold it for three seconds to enter edit mode. Adjust the numbers by rotating the control lever. After adjusting, wait for the system to save automatically—forcing a power-off will lose the data. It's recommended to check the date every month, especially before long trips, to avoid navigation and trip log time errors.

Adjusting the date on a 15-year-old GL8 is actually a three-step process: After powering on, locate the combination switch on the left side of the steering wheel, which has a button with an arrow. First, briefly press to switch to the time menu, then press and hold to enter settings. Rotate the lever to adjust the year and press to confirm; follow the same steps to adjust the month and day. I've noticed many people make the mistake of not switching to the correct gear—you must set it to ACC for the adjustments to take effect. If the display still doesn't show the changes after adjustment, you may need to visit a 4S shop to update the dashboard firmware.
