How to adjust the time on an older model GL8?
3 Answers
Time adjustment method for older model GL8: Turn on the radio power (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 hour, then press the center button of the right knob to switch to minute adjustment. Turn off the radio to complete the time setting. The Buick GL8 has body dimensions of 5238mm in length, 1878mm in width, and 1776mm in height, with a wheelbase of 3088mm. It is equipped with a 2.0T turbocharged engine paired with a 9-speed automatic transmission. This engine delivers a maximum power of 174kW and a peak torque of 350Nm.
It's quite common to encounter the issue of adjusting the time on older GL8 models, especially those from around 2005. There's a clock button on the center console with a small clock icon—press and hold it for about three seconds until the time digits start flashing, then you can adjust it. When adjusting, pay attention to the left and right buttons: one adjusts the hours and the other the minutes, with each press moving the digit by one. After setting, remember to press the clock button again to lock it; otherwise, you'll have to redo it after powering off. Also, the buttons on older cars may not be very responsive, so lightly pressing with a fingernail or cleaning the dust off the buttons can help. If the clock doesn't respond at all, it might be a blown fuse—check the 7.5A fuse in the fuse box under the driver's seat on the left side.
From my recent experiences helping others adjust the time on older GL8 models, I've noticed slight operational differences between various model years. For example, early versions without navigation screens typically require operating through the central audio control panel - just locate and long-press the button labeled CLOCK or TIME. For some post-2008 models, you'll need to access the menu via steering wheel controls, using the MODE button to switch to time settings and volume keys for adjustments. Important: never attempt this while driving - always park and shift to P mode to avoid accidental activation of other functions. If the time keeps drifting after adjustment, it's likely due to unstable vehicle circuit voltage, in which case you should check the battery condition.
