NOTE: To prevent potential issues with the firmware update, connecting a maintainer to the 12V Battery is recommended.

Verify that network connectivity is available to the vehicle by the words "3G", "4G", "LTE", or the WiFi icon appearing in the upper right corner of the touchscreen.
Verify that there is an orange down arrow in the upper right corner of the vehicle touchscreen.
- If the down arrow is displayed, skip to step 5.
- If no down arrow is displayed, the vehicle firmware might be at the latest level for the vehicle, or no request for the latest vehicle firmware has been made. Continue to the next step.
Touch Controls (vehicle icon), touch Software , under Software Update Preference, touch STANDARD , and then touch ADVANCED .
Close the window, touch Controls and then touch Software again to request the latest vehicle firmware.
NOTE: If the text "Your car software is up to date as of...." appears above Software Update Preference, the vehicle is already configured with the latest firmware. However, if a replaced component only requires a firmware update, use "Software Reinstall - Touchscreen" instead. See Firmware Reinstall - Touchscreen .
