Wrench light means "Service Engine Soon"

Service Required.

It is a service check. It means something is wrong and needs to be checked. You need to take it to a dealer or to a auto part store to have a free module check to see if it finds anything. What you do after that is up to you. I would take to get it fixed.

Wrench means, workshop needed. If it does not come back, no problem. If it keeps coming back, visit a repair shop.

diaconnect the battery for 2hrs so it loses its memory-the wrench symbol means service is due not something wrong -Denny

i'll bet there is an explanation in the owners manual, if not the dealer knows.

It means your car is due for service, oil change, etc.

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%.
