3 Answers
First, press the vehicle's one-touch start button, shift to P gear, and start the engine. Next, turn on the rear window defroster switch and press the brake pedal four times within 20 seconds. Then, turn off the rear window defroster switch and press the brake pedal four times within 20 seconds. Repeat this process several times. After that, press the menu button on the right side of the multifunction steering wheel. The LCD display will then show the vehicle's driving information, and the maintenance fuel injector prompt will disappear.
Having driven a Lexus for many years, I've learned the method to reset the fuel injector maintenance reminder light, and it's actually quite simple. First, don't start the engine when you get in the car—just turn the key to the ON position (power on without starting the engine). Then, locate the control button on the steering wheel, usually the Trip or Info button, and hold it down for a few seconds. The dashboard will then display the maintenance menu. Select the maintenance or fuel injector-related option in the menu and press the confirm button to reset. Once done, the light will turn off, and the next maintenance interval will be updated. This operation takes just a minute, but make sure the vehicle is parked safely and stably. Resetting the light is simply a reminder for owners to clean or inspect the fuel injectors promptly to prevent carbon buildup from affecting power and fuel efficiency. Regular maintenance can extend engine life, and I recommend checking every 5,000 kilometers to avoid sudden power loss while driving at high speeds. If unsure, consulting the vehicle manual or YouTube tutorials is a safer approach.
As a seasoned driver who has long owned luxury vehicles, I've handled numerous Lexus maintenance resets. The key to resetting the fuel injector indicator light lies in instrument cluster operations: Start the vehicle but don't engage the engine, use the left-side steering wheel buttons to navigate to the settings page, and locate the maintenance reset option. Different models like RX or ES may have slight variations – for instance, post-2015 models might integrate this function into the touchscreen, accessible through the infotainment system's vehicle information restart options. Resetting eliminates annoying warning lights, allowing for better driving focus. Importantly, fuel injector cleaning is essential to reduce fuel waste and emission issues – I always remind people to simultaneously check filters during maintenance to prevent minor issues from escalating into major repairs. The steps are simple but safety comes first; always test-drive after resetting to ensure system normalcy. If the light persists, it might indicate sensor issues requiring professional inspection.
