Starting a Lexus After Replacing the Battery
To start your Lexus after replacing the battery, follow these steps:
1. Disconnect the negative terminal: Before replacing the battery, it is crucial to disconnect the negative terminal first to ensure that there is no power flowing through your vehicle’s electrical system during the replacement process.
2. Replace the battery: Once the negative terminal is disconnected, you can proceed to replace the old battery with a new one. Make sure to use the correct battery type recommended for your Lexus model.
3. Reconnect the terminals: After installing the new battery, reconnect the terminals. It is important to reconnect the negative terminal last.
4. Wait for system reset: After reconnecting the terminals, it is recommended to wait for about 15 minutes before starting your Lexus. This allows the vehicle’s systems to reset properly without interruption, ensuring that all electronic components are properly initialized and functioning correctly when you start your Lexus again.
5. Start the vehicle: Once the waiting period is over, you can start your Lexus by pressing the start button with the key fob. If your Lexus doesn’t start, there are a few troubleshooting steps you can try:
