How to Turn Off Lexus Auto Start-Stop?
3 Answers
Generally, vehicles equipped with an auto start-stop system have this function enabled by default. If you wish to turn it off, the owner can simply press the auto start-stop button (usually a circular arrow containing the letter A). The dashboard will then indicate that the system is turned off. To use this function again, simply press the button to reactivate it. Here is some additional information: Conditions for turning off the start-stop function: In extremely hot weather in the south when the air conditioner is running at full capacity, it is advisable to turn off the auto start-stop function. This is because the air conditioner requires significant power consumption, and the vehicle's electrical system might not be able to support the air conditioner's operation when the engine is off, which could make passengers uncomfortable.
When I first drove my Lexus, the auto start-stop feature gave me a real headache. The engine kept shutting off and restarting constantly, especially in traffic jams where the vibrations made it quite uncomfortable. After studying the manual, I found that every model has a deactivation button - usually labeled 'A OFF' or marked with a similar icon. It's typically located either below the steering wheel on the left side or near the gear shift. Just press it (the illuminated light indicates it's off). Note that the system resets to default ON status after each engine restart, so I have to remember to press it every time I drive. I sometimes keep it active on highways for fuel efficiency, but in dense urban traffic, I always deactivate it for comfort. Overall, it's a simple and quick operation. New owners should check their vehicle manual or familiarize themselves with the button location during test drives at dealerships.
As someone who frequently works on cars, I suggest Lexus owners the simplest way to disable the start-stop system is to locate the physical button, commonly found near the gear lever or on the upper side of the steering wheel, which can deactivate it with a single press. If the button isn't obvious, checking the powertrain options in the central display's settings menu might reveal a software switch option. Remember, the system relies on battery condition; frequent start-stop cycles may accelerate battery aging, especially as the vehicle ages and the battery weakens, so timely deactivation is advised for maintenance. During regular servicing, inform the technician to inspect related circuits and sensors to ensure proper functionality. Safety is paramount during operation—avoid distracted settings while driving to prevent accident risks.
