How to Check the Remaining Battery Level of the ES300h?
2 Answers
The ES300h does not allow you to view the remaining charge of the 12V auxiliary battery, but you can check the remaining charge of the hybrid battery. Below is some information about the ES300h: 1. The Lexus ES300h is a hybrid electric vehicle equipped with a 2.5-liter naturally aspirated engine and an electric motor. The 2.5-liter naturally aspirated engine, coded A25B-FXS, delivers a maximum power of 131 kW, a maximum torque of 221 Nm, with peak power achieved at 5,700 rpm and peak torque between 3,600 and 5,200 rpm. 2. The 2.5-liter naturally aspirated engine features hybrid fuel injection technology and utilizes an aluminum alloy cylinder head and block. The electric motor paired with this engine produces a maximum power of 88 kW and a maximum torque of 202 Nm. The Lexus ES300h employs a MacPherson strut front suspension and a multi-link independent rear suspension. 3. The vehicle's dashboard displays the remaining charge of the hybrid battery but does not show the remaining charge of the 12V auxiliary battery. The ES300h is not a plug-in hybrid but a conventional hybrid electric vehicle. Hybrid vehicles offer a longer driving range compared to pure electric vehicles and lower fuel consumption than traditional gasoline-powered cars. The Lexus hybrid delivers smooth power output and excellent fuel efficiency.
The most convenient way to check while driving is to look at the instrument panel. There are buttons on the right side of the steering wheel—press the arrow keys on the steering wheel to switch to the display area and find the "Power Flow" or "Energy Monitor" option. A battery icon and the remaining charge percentage will appear on the screen, usually indicated by a blue bar showing the charge level. When the battery is low, the car will automatically start the engine to recharge. When the charge is high, you can drive in pure electric mode for a while longer. I usually check it at red lights or when parked, adjusting my driving habits—like avoiding sudden braking—to recover more energy. Making it a daily habit to check helps extend battery life. If you frequently get low-battery warnings, remember to check the vehicle status or visit a service center for diagnostics.
