In the next 2 weeks, your Model S will display an alarm clock icon in the status bar letting you know that new software is available. Model S updates its software wirelessly, providing new functionality throughout your term of ownership. The process to install these enhancements is outlined below.
The first time you enter your Model S after an update is made available, you will be shown a scheduling dialogue box. You can install immediately, confirm the suggested time, or schedule an alternate time. Once scheduled, the icon will change color from yellow (unscheduled) to white (scheduled). At any point before installation begins, you can re-schedule the installation.
IMPORTANT: Model S must be in Park and not driving when new software is being installed. A software update can take up to 2 hours to complete so be sure to select a time when the car can sit idle for this period.
If your car is charging when the update is scheduled, charging will temporarily stop and restart after the software is installed. If you are driving when the installation is scheduled, the installation will be cancelled.
