NO.

Get your car serviced and it should go off. It is time to change your oil.

this light can come on even thought service is not actually due. if the service was performed and the light was not on at the time, sometimes you cannot reset them if they are not actually lit, or 99% of the time the technician forgets if the light was not on. stop by your shop and they can reset it for you in just a few moments, and for no charge. good luck!

PRESS AND HOLD IN THE TRIPOMETER RESET BUTTON. WITH IT IN, TURN THE KEY TO THE ON POSITION WITHOUT STARTING THE ENGINE. THE DISPLAY WILL COUNT DOWN IN HASH MARKS FROM 6 TO 0. AFTER IT REACHES 0 RELEASE THE TRIPOMETER RESET, TURN THE KEY TO THE OFF POSITION. ONCE YOU RESTART THE LIGHT SHOULD BE OFF.
