I'm sorry, torque wrench, but on this car it's a more serious issue.

The wrench light on your Five Hundred is coming on due to a fault with your drive-by-wire throttle system. Have a diagnostic test performed as soon as possible. The electronic throttle bodies on these cars are known issues and will render your engine powerless potentially.
wrench light is a service light, It will come on because service is due to the cars maintaince schedule. It needs to be reset with a scan tool.
