How to adjust the time on an old Buick GL8?

Turn on the radio power (POWER), locate the RPT button on the panel, press and hold it for 3 seconds. When the screen display starts blinking, rotate the knob on the right to adjust the hour, then press the center button of the right knob to select and adjust the minutes. Turn off the radio to complete the time adjustment. More details are as follows: 1. The new Buick GL8 features a three-dimensional waterfall grille, multi-dimensional blue Bi-Xenon-HID headlights, a 360-degree wraparound integrated interior design, ice-blue ambient lighting, and other design elements that inherit the design language of the new generation Buick family. It also comes equipped with OnStar All-Time Online Assistant and Buick's high-standard Quiet-tuning noise reduction technology. 2. The new GL8 is equipped with a brand-new 2.0T turbocharged engine, which delivers a maximum power of 191 kW and a maximum torque of 350 Nm. The engine reaches its maximum power at 5400 rpm and its maximum torque between 2000 and 5000 rpm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. It is paired with a 6-speed automatic transmission.

I've been driving an older Buick GL8 for many years, a model from around 2010, and adjusting the time is mainly done on the dashboard. First, turn the key to the ON position without starting the engine. Then press the SET button near the dashboard, usually a small button in the lower left corner, and the time setting menu will pop up on the screen. Use the directional control buttons to adjust the hours and minutes, and press SET to confirm and exit. The system in older cars is very simple, with no high-tech features, so if the buttons don't respond, you might want to check if the fuse is blown—look for the relevant dashboard circuit fuse in the fuse box. I recommend adjusting the time during the day when there's good light to avoid any misoperations that could affect driving safety. Also, note that an inaccurate time can affect GPS and trip recording accuracy. Regular calibration helps maintain the vehicle's overall performance stability. I always check it twice a year to ensure everything runs smoothly.

Adjusting the time on my GL8 is pretty straightforward as a regular car owner. First, turn the key to the second position to power up the dashboard, then press the CLOCK button on the steering wheel or center console to enter the settings. The screen will display the current time flashing, and you can adjust the numbers using the rotary knob or +/- buttons. Confirm once you're done. During actual operation, I've encountered a few failures and realized it's because the car wasn't in P mode or the power was unstable—make sure the vehicle is parked safely. Setting the correct time is crucial for navigation synchronization, especially since older car navigation systems tend to drift, so accurate time improves reliability. If the buttons don't respond, try checking the manual or online video guides before attempting manual disassembly to avoid damaging the circuits. Regularly checking the settings during maintenance can prevent unexpected issues, saving both money and hassle.

I enjoy tinkering with older car models, so let me explain the Buick GL8's time adjustment from an electronic system perspective. With the vehicle power in ACC mode, press the INFO button to access the main menu and locate the clock option for editing. Use the control knob to adjust hours and minutes, then simply confirm. The button design in older models is basic - if the screen doesn't light up or buttons aren't responsive, it could indicate a circuit short or fuse issue; check if the instrument panel fuse is intact. Inaccurate time settings can affect onboard diagnostic data, so I recommend combining this adjustment with other settings like date to improve system efficiency. Be patient during operation - it typically takes just 2-3 minutes to complete.
