3 Answers
Here is the method to reset the maintenance reminder for Infiniti QX50: 1. Press and hold the reset button "A" while stepping on the brake pedal. 2. Turn the ignition switch to "on" without starting the engine. 3. The characters "INSP" will flash or the display will blink. 4. Continue holding the reset button "A" until "..." appears on the display. 5. Release the reset button "A" and take your foot off the brake pedal. 6. Turn the ignition switch back to the "Off" position. The reset process is now complete. Here is additional information: 1. When the maintenance light comes on, it means the vehicle needs servicing. Some models cannot be reset manually and require professional diagnostic equipment. 2. Automotive technology better protects vehicle components. However, maintenance of some critical parts still needs to be performed on schedule to ensure the vehicle's safety, economy, and reliability. If the vehicle operates in harsh conditions, specific maintenance may be required even between regular intervals.
Last time I did the maintenance reset for my QX50 myself, and it was quite simple. First, completely turn off the engine, then sit in the driver's seat and locate a small button on the left side of the steering wheel, marked with an icon like mileage or something similar. Hold that button down without releasing it, then turn the ignition key to the ON position—this means the dashboard lights up fully but don't start the engine. At this point, keep an eye on the dashboard while holding the button for about 5-10 seconds. You'll see the wrench icon start flashing, then quickly release the button. Immediately press the button again for two or three seconds, and the maintenance light will go off. Remember to perform the steps smoothly without releasing the button midway, or you'll have to start over. I failed once before because I released the button too quickly. After completing the reset, take the car for a short drive to confirm the icon disappears, so you won't worry unnecessarily next time.
I've studied the maintenance light reset procedure for Infiniti vehicles, and it actually doesn't require a trip to the dealership. With the engine off, locate the small square button to the left of the steering wheel and hold it down. While keeping it pressed, use your other hand to turn the ignition to the ON position (don't start the engine). Watch the instrument cluster until the wrench service indicator starts flashing, then immediately release the button. Quickly press the button once more, wait two seconds, and you're done. The whole process takes less than 20 seconds - much faster than expected. However, I recommend resetting it promptly after each service, otherwise the warning light might cause misjudgment of vehicle condition at the next maintenance interval. Some older models may have slightly different procedures, but this method works for the current-generation QX50.
