Unfortunately, it is likely any car's battery will go flat if it is left for a three-month period. The easiest way to get around this is to put the car on a trickle charger, although this is only really possible if you have a drive or garage. Your next option would be to ask someone to drive the car for 30 minutes each month – that'll be enough to keep the battery in good health.

If the battery does go flat, you should be able to jumpstart it like you do any other car, however I'd consult the dealer or the car's handbook in case there's a particular procedure to follow that is unique to the Yaris.

The traction battery is separate to the 12V battery and should have plenty of power left in it when you return from your holiday.
