Scheduled maintenance on a vehicle typically asks you to have some fairly basic work done: change the oil, top off the fluids, test the battery charge, and so on. As vehicles have incorporated more computer technology, however, software updates have also become an important part of a car's upkeep.

The infotainment systems in newer vehicles incorporate a number of technologies, from navigation to satellite radio. Vehicle software has also become essential for a number of advanced systems, such as automatic emergency braking.

Just as your smartphone will ping you with an alert about how a software upgrade is available, a vehicle's infotainment system may let you know when an update is available. Some of these enhancements can be made rather easily, while others may inconvenience you for awhile.

Automakers typically make a note of any software upgrades on their website, so you may want to get into the habit of checking the site once a month to see what is available. Rich Ellis, writing for the automotive site DriverSide, says an upgrade might add new features, correct flaws in the system or improve its security, or even boost the vehicle's performance. Brian Turner, writing for the Canadian automotive site Driving, says updates can also be for relatively minor issues, such as slight improvements to the HVAC system.

Since drivers may ignore these updates, they might not get regular notifications of changes being made to the vehicle's systems. However, an automaker will certainly send out word of an update if it relates to a recall or if the modification is otherwise considered critical to safety.

There are varying methods of updating a vehicle's software. Some automakers have sent USB drives to drivers. Others ask drivers to complete the update themselves by downloading information from a computer and transferring it to the vehicle system. Over-the-air updates are becoming increasingly common, allowing updates to happen automatically if the vehicle is in range of an open wireless network.

One inconvenience related to software updates is the fact that the download and installation can take a long time to complete. Turner says this can potentially lead to higher maintenance bills if you get an update done as part of a tune-up, since you'll be charged for the amount of time it takes for the software to be updated.

Automakers often say the vehicle needs to be running while the update is taking place. For this reason, they advise that the software upgrade should be done in a well-ventilated area to prevent exhaust fumes from building up.

Of course, it's easier to simply let the update proceed during your commute or on a long trip. You might be able to complete the process over a few different drives if the wireless download automatically pauses when the vehicle is turned off or the connection is lost. However, you may also not be able to drive the vehicle while the downloaded software is being installed.

It also helps to prepare for any potential loss of information that might occur when a system is upgraded. Make sure you have data points such as navigation destinations and favorite radio stations saved before you begin the update.
