What does the Lexus READY light mean?
2 Answers
When the READY indicator appears on the dashboard of an electric vehicle, it means "the vehicle has completed all preparations, successfully started, and is ready to depart at any time." Here are some relevant explanations: 1. Display status: Both electric vehicles and hybrid new energy vehicles show this startup status. Since new energy vehicles produce no engine noise after starting, it's difficult for drivers to determine whether the vehicle has started normally. Hence, the READY indicator light is used to notify the driver. Icons on the car dashboard represent different meanings, and dashboard lights serve to inform the driver about the vehicle's status. 2. Precautions for electric vehicles: Periodically performing a deep discharge on the battery helps "activate" it and can slightly increase battery capacity. Generally, it's recommended to perform a complete discharge periodically. After the first under-voltage protection, the battery voltage may recover to a non-under-voltage state after some time. Using the battery again in this state can cause significant damage. After completing a full discharge, performing a full charge may result in a noticeable improvement in battery capacity.
I've been driving a Lexus hybrid for several years, and the READY light has become my signal that the vehicle is prepared. When this light illuminates, it indicates that the electric system, battery, and control modules are fully activated, meaning the car is ready to drive at any moment. It lights up after you press the brake and push the start button, showing that unlike traditional cars where the engine roars to life, the vehicle starts quietly via the electric motor. This feature is particularly useful in city driving—for instance, when stopped at a red light, the light remains on while the engine might be off to save fuel, and the car responds smoothly as soon as you press the accelerator. I always make sure the light is on before starting off during daily drives to avoid malfunctions or battery depletion, a habit that has saved me considerable fuel costs and hassle. In essence, the READY light signifies the hybrid system's efficient operation, helping reduce noise pollution and emissions.
