How to Reset the Maintenance Light on a 2015 Highlander?

Find and hold the "A" button while also pressing the brake pedal. Turn the ignition switch to "on" but do not start the car immediately. Keep holding the "A" button, and after a moment, you will see "..." appear on the dashboard. Release the brake pedal and the "A" button. Turn off the vehicle's power to complete the maintenance light reset. Sometimes, you may need to press and release the button several times to clear the maintenance light.

I remember spending quite a while figuring out how to reset the maintenance light on my 2015 Highlander for the first time. First, turn the key to the ON position without starting the engine, then press the ODO button on the dashboard to switch to the total mileage display. After turning off the power, here comes the crucial step: hold down the ODO button continuously while turning the key back to the ON position. Keep an eye on the dashboard without releasing the button, and in about five seconds, you'll see the odometer flash and reset to zero, with the little wrench icon disappearing immediately. Finally, turn off the power and restart the car to complete the process. The whole thing actually takes no more than 20 seconds, but it's important to operate while the power is on. Checking the manual beforehand to confirm the button location can save a lot of trouble. I recommend resetting it immediately after maintenance to avoid being distracted by constant reminders while driving.

Last time I got my car serviced at the 4S dealership, I specifically learned this reset method from the technician. Before starting the engine, power on the ignition first and use the TRIP button on the right side of the steering wheel to bring up the mileage page. After completely powering off, hold down the TRIP button while turning the ignition back on. At this point, the dashboard numbers will start flashing. Keep holding for about five seconds until the wrench symbol disappears, indicating success. The key is to perform the operations quickly and consecutively - pausing midway can easily lead to failure. After resetting, it's best to drive about ten kilometers to observe whether the warning light reappears. I remember one time I pressed the button too lightly and failed to reset it properly - it took me three more attempts to get it right. You need to press firmly all the way down.

Resetting the maintenance light for the 2015 Highlander requires several steps: 1. Turn on the power without starting the engine; 2. Press the ODO button on the dashboard to switch displays; 3. Turn off the power; 4. Hold the ODO button while turning on the power; 5. Keep pressing until the wrench icon disappears. Continuous finger pressure is required throughout the process, and success is confirmed when the odometer resets. It's more stable to perform this operation when the engine is cold to avoid misjudgment by the onboard computer. After completion, remember to test drive to confirm. If repeated attempts fail, it might be due to the maintenance cycle not being reset, and a visit to the repair shop for a computer diagnostic is recommended.

I've figured out some tricks for resetting my old Highlander. Turn the key to the ON position and immediately press the trip meter button - this action must be decisive. The most critical step is pressing both buttons after turning off the power: the left hand turning the key and the right hand pressing the buttons must be perfectly synchronized, even one second early or late won't work. While holding the buttons, you can feel a slight vibration in the instrument cluster - wait about five seconds until the indicator light goes off before releasing. Once during rainy weather, I found the buttons slippery and prone to mistakes, so now I always keep a dry cloth handy to wipe my hands. After resetting, I recommend driving on the highway for a while to let the system perform a more reliable self-check.

The method learned from the manual is actually quite simple: With the vehicle powered on but not started, navigate to the trip page. Power off to enter standby mode, then firmly press and hold the odometer button with your index finger without releasing. With the other hand, power the vehicle back on. At this point, the dashboard will provide ticking feedback—count about five ticks, and the yellow wrench indicator will disappear. For first-time attempts, it’s advisable to sit in the passenger seat and have someone assist with pressing the power button for added safety. If the light remains on after completion, it may indicate uncleared maintenance data from the last service, in which case a professional device will be needed to reset it. Regular resets are quite helpful for accurately recording the vehicle’s true condition.
