Procedure notes
Where is the battery located in a Lexus LS400?
The video above shows you how to replace the battery in your 1998 Lexus LS400. We recommend changing the battery in Lexuss every 4 years. Although some batteries last much longer, most batteries begin breaking down chemically after four years, so you could experience dimmer headlights and other negative effects before you have a dead battery in your LS400 that you need to replace.
The battery location in a Lexus LS400 can typically be found in the engine bay, but may be in the trunk, fender or inside of the vehicle. You may need to remove the air filter housing, a plastic engine cover or parts of the cowl to find the battery in your LS400. See exactly where the battery is located in your 1998 Lexus LS400.
Replacing the battery in your LS400 involves removing the terminals. When you reconnect the terminals, your radio presets are likely to be cleared out. In some LS400s, you may need to re-enter a security code to get your radio to work again. Check for this code in your owners manual - it will usually be either a sticker or small card in the booklet. If you can't find it, call Lexus and they will give you the code for free. In many Lexuss, the transmission "learns" how you drive over time and makes adjustments, so you may experience altered driving dynamics as your car re-learns your driving style after changing the battery.

在 雷克萨斯 LS400 中，蓄电池位于何处？
上面的视频展示了如何更换您的 1998 雷克萨斯 LS400 车辆的电池。 我们建议每隔 4 年为 雷克萨斯车型 更换一次电池。 虽然部分蓄电池寿命更长，但大多数蓄电池在使用四年后会开始出现化学性能衰退。因此，在 LS400 的蓄电池彻底失效、需要更换之前，你可能就会先遇到前照灯变暗等问题。
在 雷克萨斯 LS400 车辆中，蓄电池通常位于发动机舱，但也可能位于后备箱、车门板或车内。 您可能需要拆除空气滤清器罩、塑料发动机盖或车头罩的某些部件，才能找到您的 LS400 车辆上的蓄电池。 请查看您的 1998 雷克萨斯 LS400 车辆中蓄电池的具体位置。
在您的 LS400 上更换电池需要拆除端子。 当你重新连接端子时，收音机的预设设置可能会被清除。 在某些 LS400s 车型中，您可能需要重新输入安全码才能让收音机恢复正常工作。 在您的用户手册中查找此故障码 - 它通常会以标签或书本内的小卡片形式存在。 如果找不到，请联系 雷克萨斯，他们将免费为您提供该代码。 在许多 雷克萨斯车型 车辆中，变速箱会随着时间推移学习你的驾驶习惯并进行相应调整，因此在更换电池后，车辆重新学习驾驶风格时，你可能会感受到驾驶动态的改变。
