How do I change kilometers to miles on my U-Connect navigation system in Jeep Cherokee 2015?

Question edited for clarity.
Question moved to model category.

In the 2015 Jeep Grand Cherokee is is F08 Emissions Sensors

Jeep Grand Cherokee (WK2; 2011-2021) fuses

Fuse Box Diagrams https://fuse-box.info > jeep > jeep-grand-cherokee-wk...
But in your 2015 Jeep Cherokee, they are not listed, so they are likely a function of the ECM.

Hopefully our Electrical Tech Jeff Armer will be along with the factory data

Hi there's this website something like reliable-store and it is very amazing for manual for repairing servicing anything
someone on fixya recommended it to me and I thank him even today

Check with another dealer and see what he says. Ask for written statements confirming what was told to you.

There is usually a setting in the computer interface. You must be stopped to change the setting.

regular maintenance, should have been done long ago, plugs do wear and the gap changes, besides its cheap insurance

The information for this should be in your owners manual. If you don't have an owners manual I would call a dealership and ask them. Different engines require different maintenance. I personally change mine about every 50,000 miles in my gasoline vehicles.

access enter new destination menu, then add new or delete existing

Hi, The time is set threw your head unit. Go to the settings menu and find a country in the same time zone as you. To change to kilometers, it is set threw your instrument cluster, also threw the setting tab with your steering wheel buttons.
