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 brake fluid in your 2009 Kia Optima is easy and should be done once a month. On some Kias, the owners manual suggests pumping the brake pedal 25 times before looking at the fluid level, be sure to check your owners manual to see if this applies to your 2009 Optima. In addition to checking the brake fluid level, you want to look at the color of the brake fluid in your Optima - if it is dark in color or it has been more than 2 years since you have changed it, you should consider having it changed - this will help make the internal components (which are expensive) last much longer.If you need to add fluid to your Optima, it is important to check your owners manual for the correct type to add - it likely be either DOT 3, DOT 4 or DOT 5, also known as silicone brake fluid. Be sure to discard bottles of brake fluid that are over a year old - brake fluid sucks the moisture out of the air and the water vapor in the fluid can quickly rust out the brake lines in your Optima.

检查你的 2009 起亚 Optima 的制动液非常简单，建议每月进行一次。 在一些 起亚车型 上，用户手册建议在检查制动液液位之前，踩踏制动踏板 25 次，但请务必查阅您的 2009 Optima 用户手册，确认是否适用于您的车辆。 除了检查制动液液位，还应观察 Optima 中制动液的颜色。如果颜色发暗，或者距上次更换已超过 2 年，应考虑更换，以延长价格昂贵的内部部件的使用寿命。如果需要为 Optima 添加制动液，务必查阅车主手册，确认应添加的正确类型；可能是 DOT 3、DOT 4，或称为硅基制动液的 DOT 5。 请务必丢弃使用超过一年的制动液瓶装——制动液会从空气中吸收水分，液体中的水蒸气会迅速导致Optima的制动管路生锈。
