SOFTWARE UPDATES

Over-the-Air (OTA) technology allows some vehicle software updates for certain vehicle components to be downloaded and installed over a wireless connection. This technology provides a convenient way to update your vehicle with some of the latest available software. This functionality is available on Connected Services equipped Cadillac electric vehicles in Europe.

1. Download: Updates are automatically downloaded in the background. 

2. Installation:  After the download is complete and your vehicle is parked, you’ll receive a notification on your center display to install the update. When you’re ready to begin, tap “install” and follow the on-screen prompts, which will instruct you to turn off the vehicle. This process can take up to 20 minutes to complete and can’t be stopped once started. Your vehicle will be disabled and cannot be driven during the installation. 

To help ensure that your vehicle software update is successful, your vehicle needs to be connected to a mobile device hotspot, home network or public network. Avoid locations with poor signal, such as underground car parks, under bridges, or enclosed structures, as they may interrupt the update or cause delays. 

The first step is to accept the download of the software. Download times will vary depending on the size of the update and the wireless signal strength. You can continue to use your vehicle normally during the software download.

Once the software is downloaded, you can begin the installation process. Your vehicle will be immobilized (i.e., will not be usable/drivable) during this portion of the process. This cannot be overridden once the installation has begun.

Vehicle software update installation times will vary depending on the component being updated and the contents of the update. The in-vehicle notice will provide the estimated completion time for the installation. Generally, the software installation is expected to take 20 minutes or less.

During the software download, you can continue to use your vehicle normally. The download will automatically pause and resume if you turn your vehicle off or lose network connectivity during the download (e.g., if you pull into a parking garage).

During the installation, the vehicle will be disabled and cannot be driven for most  updates: 

• Please park your vehicle in a safe and secure location
• You will not need to remain in your vehicle during the installation
• Features, such as door locks, windows and chimes, may not work during the installation
• If you leave the vehicle, do not lock occupants inside

 You may notice one or more system resets during the installation process.

To confirm if your vehicle supports Over-the-Air vehicle software updates, go to the "Settings" menu in your infotainment system and look for either of the following: 

• Under the "System" tab, go to the "Vehicle Software" section and look for "Updates"
• Choose "Software Information" and then look for "System Update"

If you see these options, your vehicle supports Over-the Air vehicle software updates. Steps may vary by vehicle. To be eligible for vehicle software updates for your vehicle, you must have subscribed to and activated Connected Vehicle Services for that vehicle.

Note: If you have not subscribed to and activated Connected Vehicle Services for the vehicle , the vehicle will not be eligible for vehicle software updates.

Depending on the specific message or error received, many vehicle software update situations will resolve on their own through natural use of the vehicle. For example, a message regarding a download or connection error may occur in situations where the vehicle has limited cellular connectivity. In that case, the situation will be resolved once the vehicle is moved back into an area with sufficient cellular connectivity. Another type of message that could result indicates the vehicle conditions for software update download/installation are not ideal at this time. In this case, a drive cycle could improve conditions, such as battery charge, by turning off autostop during your next drive cycle for more aggressive battery charging.

For remaining questions, you can contact Cadillac Support.

Yes, for both download and installation notifications, you can do any of the following:

• Select "Dismiss/Next Time" or dismiss the screen by pressing the "X" in the upper-right corner of the message. You will be reminded again after your next ignition cycle
•  Select "Remind Me Later"; you will have the option of being prompted about the update again after a duration of your choosing
• Select “Schedule” then select a time that you will not be using the vehicle when you’d like the update to install
• You can also choose to ignore the message and continue using your vehicle normally. You will be reminded again at a later time

Overall, the system will attempt to remind you about the update (dependent on the type of update) and then will stop presenting the download or installation notice. If you choose “Decline/Delete”, you will not be reminded again, and the update will not occur. Instead, you can take your vehicle to a Cadillac service partner to perform the update at a later time.

Go to "Settings" in your infotainment system and look for either of the following. Steps may vary by vehicle. 

• Under the "System" tab, go to the "Vehicle Software" section and look for "Updates."
• Choose "Software Information" and then look for "System Update.”

If you choose “Decline/Delete”, you will not be reminded again, and the update will not occur. Instead, you can take your vehicle to a Cadillac service partner to perform the update at a later time.
