Yaris Hybrid 12V battery

It's under the back seat, but its panel is kept in place by a couple of these plastic pegs:

You'll need a little screwdriver to extract the peg and his surrounding ring.

Here is it, removed from its housing.

Now it's possible to remove the plastic cover.
I've found it easier to start from the side of the seat, pulling to detach the cover.

Here is the 12V battery:

Lesson learned: always keep a screwdriver in the car, in case you'll need to charge the 12V battery while on the road.
Shame on you Toyota: why not just use a tool-less retention mechanism?
Every car driver, hybrid or not, has some story to share about low batteries, so access to the 12V one should be as easy as possible.

    Well done! The salesman at the garage didn't even know the yaris hybrid could be jump started if the battery had depleted after standing for 10/12 days after non-use. He knew where the battery was but very little about the access. The result was to buy a Mazda3 1.6 A pity really as I would have bought the hybrid.

  2. Sorry about that. Competent salesmen are on the verge of extinction.
    Anyway the 12V battery should last more than 10 days. Older Priuses stood still for a month without requiring jump starting.

  3. What you wrote is WRONG: you don't need any screwdriver to extract the peg!
    Just push it in the middle, as stated in the manual... and it will pop out.
    The trick is pushing really hard, but not with your finger because it's too soft... you can use any tool made of any hard material. Plastic is perfect, because it doesn't scratch the peg.
    Push harder and it will work, believe me! :)

    1. I've tried that before resorting to the screwdriver, but I gave up fearing it would damage the peg since the pressure was too much.
      Anyway you'd still need a tool on the road.
