Hello I will help you with your question,
You can go quite a while just check the fluids over to be sure nothing is low and visit the dealer as soon as you can. The warning is a reminder it does not shut off any systems.
Let me know how I can help you
Primarily the engine oil, if that is between the add and full lines you should be good to drive that distance.
Are you down to 0% on the oil life?
This means the computer has determined that the life of the oil has been used up and after 10 more Kms the warning will stay on until the service is done and the monitor is reset.
1000 miles is a lot and you really should have it changed before you drive that far but if you have to listen for abnormal noises and keep an eye on the warning indicators.
The reminder does not mean that the oil is low or the other fluids are either just that it is time for service.

Glad to help and thank you for using JA!!
