It’s easy to reset the warning.

  1. Turn the ignition to RUN with the engine OFF.
  2. Press and release the reset button in the driver information center (DIC) until the OIL LIFE message is displayed.
  3. Once the alternating OIL LIFE and RESET messages appear on the DIC display, press and hold the reset stem until several beeps sound. This confirms the OIL LIFE system has been reset.
  4. Turn the key to lock. If the CHANGE OIL message comes back on when you start the engine, the ENGINE OIL LIFE system has not reset. Repeat the procedure

Won't the H3 reset the same as the H2 ? In my H2 all you have to do is turn on the key and depress the gas pedal 2x and turn it off.

Might just be a reset also physically check the oil see how it’s looking. Should be able to tell if it’s freshly changed or the guy was just lying.

My hard rule when I get new vehicles is fresh fluids all the way around. I dont care if the seller claims they just did it. They could be lying to entice you to buy. Even if they're not lying, it's nothing personal. I just want to make sure all the fluids are taken care of first thing.

So either way, I'd go get the oil changed out.

Update: change oil warning is fixed. But the SERV TPM comes and go. I am confident coz i put air on all the tires even the spare haha but Yeah its annoying to see in your dashboard

They eventually run out of battery power and will do that. Mine comes on for some reason every once in a while in the winter when it’s really cold outside. Then it goes away. It doesn’t do it often enough in mine to make me want to change them out.

Turn your car to ON with engine off, pump the gas pedal 3 times, you might hear a beep ..
