The oil can usually means needs oil and the spanner means time for a service
you are low in oil and you need a service
The spanner symbol on the dashboard of a Peugeot 307 indicates that the vehicle is due for a service or maintenance check. It serves as a reminder for the driver to schedule an appointment for routine maintenance, such as an oil change or inspection. If the light remains on after servicing, it may require resetting to turn off the warning indicator.
Maintenance servicing is due (oil/air filter etc).
I have twice had this symbol become illuminated and on both occasions it related to low oil levels. Do not be fooled into thinking that you immediately need to have a CPU diagnostics check. This can become expensive and can be totally unnecessary.

The symbol of a wrench and an oil can on the dash of a Chevy Trailblazer means that your vehicle needs oil. If the light doesn't go away oil is added, you need to take your vehicle in for service.
