The Service Interval Indicator can only be reset with the VAS 5051 or similar diagnostic tool connected to the data link connector of the car.

All the different lights you get on the dash of any vehicle, have
been there since 1980. That is 31 years. Nothing has changed
since then ,unless you were on another planet

Repair system as necessary

The wrench light indicator is a reminder that you are do for your next service(For example:oil change, air filter change, trans fluid change and so on) base on the miles on your car. A lot of people just get a oil change and have the light reset. If you read your car manual book it will tell you what service you need to do. Note: light come on every 3,000 miles and you can reset any time you want.
How to reset light:
1.with headlight off, turn the key on. Do not start the car.
2. On the left side of th dash below the heat vent there is a button that says "sel reset". push that button until you see "oil life" and a percent on the gauge display screen.
3.Now while on the oil life display, push and hold the "sel reset" button until screen start to flash. you might have to hold for 45sec.
4.when the screen start flashing, release button and hold it down again. might have to hold for about 45sec.

if you did it right the percent should go up to 100% and the wrench light should go out.

With the key sitting in the ignition but NOT on (not even accessories...the key is in in there but literally just about to fall out) push and hold the wrench button. Count 5 seconds, start the car while still pushing the wrench button and then push the min button on your clock. You must be holding the wrench button and the min button at the same time to reset the service message.
To test if you've reset properly, turn the car off and start it again. If you've reset properly the 'SERVICE NOW' will not appear and is automatically reset for 5k miles.

HI there, this light has illuminated for a serious reason. It is instructing you to take this vehicle to the nearest service dealership for a computer diagnostic scan. there may be an issue within the engines normal operation cycle and, you will need to find the problem,via diagnostic scan. Once the scan is done, the service tech will be able to pin point the issue and shut off this warning light. i suspect a bad sensor of some sort or, a lose gas cap.

Please rate and god bless:)

Note: the Service Reminder Indicator displays 3 messages: OEL, IN 01, and IN 02. These display to alert the driver to follow the items listed under the manufacturer's service interval.

If needed, press the odometer reset button until "IN 01" appears and then press the clock reset button until five dashes appear. If needed, press the odometer reset button until "IN 02" is displayed and then press the clock reset button until five dashes appear. To exit reset mode, turn the ignition switch on and when "IN 01" appears, turn the ignition switch off

The negative number means the car should have had it's oil changed that many miles ago. Oil life starts at 100% for new oil & counts down every 10%. At 15% the display will always show, which means it's near time to change the oil.

usersteve83, your oil may have been changed but the timer not reset. Reset the timer as shown...
1. Turn ignition to the "ON" position. (do not start engine)
2. Press SEL/RESET repeatedly until the oil life indicator is displayed.
3. Press & hold the SEL/RESET for about 10 seconds until it blinks then let go of the button.
4. Press the SEL/RESET again for about 5 seconds or until the oil life indicator resets to 100%.
