Procedure notes
This video shows you how to open the hood in your 2023 GMC Sierra 2500 HD. Popping the hood, or bonnet, on your Sierra 2500 HD is a two step process, you need to release the hood latch inside your Sierra 2500 HD and then you need to release the safety latch under your hood in the front of your Sierra 2500 HD. The video above shows you the location of both hood latches.
Sometimes, the hood on GMCs gets stuck and won't pop up after the interior latch is released. If you need to open the hood with a stuck latch on your Sierra 2500 HD, simply pull up on the hood and it should pop up for you to release the second latch. Another option is to pull the interior hood release, then bang on the hood to see if that pops it open.
If your hood still won't open, you may have a broken hood release cable. Opening the hood on your Sierra 2500 HD with a broken cable requires you to use a coat hanger to reach through the grille and release the latch on the bottom of the hood latch. Sometimes, especially on older Sierra 2500 HDs, you may have difficulty getting your hood to latch when you close it. In this case, the interior release lever on your 2023 GMC Sierra 2500 HD is probably stuck in the “open” position – push the release lever back and forth several times and then try to close your hood.

本视频演示如何在您的 2023 GMC Sierra 2500 HD 车辆上打开引擎盖。 打开Sierra 2500 HD的引擎盖是一个两步过程，你需要先在Sierra 2500 HD内部释放引擎盖的锁扣，然后需要在Sierra 2500 HD前方引擎盖下的安全锁扣处释放安全锁扣。 上述视频展示了两个引擎盖扣具的位置。
有时，GMC车型 的车顶会卡住，在释放车内锁扣后无法打开。 如果你需要在Sierra 2500 HD的引擎盖卡住的情况下打开引擎盖，只需向上拉引擎盖，它应该会自动弹起，以便你释放第二个锁扣。 另一种方法是拉起车内顶盖释放杆，然后敲击车顶，看看是否能将其打开。
如果车顶仍然无法打开，可能是百叶窗释放拉索断裂了。 在Sierra 2500 HD的引擎盖缆绳断裂的情况下，需要使用衣架从格栅处伸入，拨动引擎盖下方的锁扣以打开引擎盖。 有时，尤其是在较老的 Sierra 2500 HD 上，您在关闭引擎盖时可能会遇到引擎盖无法正常锁紧的问题。 在这种情况下，您的 2023 GMC Sierra 2500 HD 车辆内部的车盖释放手柄可能卡在“打开”位置——反复推拉释放手柄几次，然后尝试关闭车盖。
