Source note on shared footage
We have a massive and growing video library, but we don't have everything...yet.
Car companies often use the same engines in different cars. They also slightly alter the styling and sell the same car by two different names (amongst other tricks to help offset development costs).
Our system selects the most applicable video for your car based, in part, on these characteristics. The video displayed may not look exactly like your car, but may be relevant enough for you to get a good idea how to do it.

我们有一个庞大且不断增长的视频资料库，但还没有全部内容……
汽车制造商经常在不同车型中使用相同的发动机。 它们还略微调整了外观设计，并以两个不同的名称销售同一款车（以及其他一些技巧，以帮助抵消开发成本）。
我们的系统会根据这些特性，部分地选择最适合您车辆的视频。 视频中显示的内容可能与您的车辆外观不完全相同，但可能足够相关，让您了解如何操作。
Procedure notes
Checking the oil in a Sonoma is fairly easy and should be done once a month. Note that most GMC have an oil pressure gauge next to the speedometer - this gauge does not tell you what your oil level is, but rather uses an oil sensor to indicate the oil pressure in the engine. If you have an oil light illuminate in your Sonoma, this means your oil pressure is either high or low. The video above will show you how to check the oil level in your 1991 GMC Sonoma by taking an accurate dipstick reading. Make sure your engine is cold when you check the oil in your Sonoma. Otherwise the dipstick will read slightly low. In addition to checking the oil level, you also want to look at the condition of the oil when you have the dipstick out. If the oil in your Sonoma is dirty or smells like gasoline, you probably need an oil change.
If you notice that the oil level in your Sonoma is extremely low or empty, fill it up and check it again the next time you drive. If it is extremely low again, have your mechanic take a look before driving it much more.

检查Sonoma的机油相当简单，应每月进行一次。 请注意，大多数 GMC 车型在车速表旁边都设有机油压力表，该表并不能显示机油液位，而是通过机油传感器来显示发动机内的机油压力。 如果你的Sonoma车辆中机油灯亮起，说明机油压力要么过高，要么过低。 上述视频将向您展示如何检查您的 1991 GMC Sonoma 的机油液位，通过准确读取油尺数值来完成。 检查Sonoma机油时，确保发动机处于冷态。 否则油尺的读数会略低。 除了检查机油液位外，当你取出油尺时，还应观察机油的状态。 如果您的Sonoma机油变脏或有汽油味，您可能需要更换机油。
如果发现您的 Sonoma 机油液位极低或为空，加注后下次驾驶时再次检查。 如果冷却液仍然极低，务必在继续驾驶前请技师检查。
