Automatic Engine Start Stop Button

I see this Button on some videos/photos but not others. Can someone explain? I live in a cold climate where having the engine shut off during a traffic stop=no good. Thanks!

The US LE model is the only '19 Rav4 with auto s/s, all other gas models do not have auto s/s.

Thanks, why is that? I have seen LE models without it as well so does not make sense. This would be a great feature to have.

I've seen many US LE videos and looked at a bunch of those at the local dealer, they all had it, haven't seen a Canadian LE with it tho.

Next time you see an LE without the S/S disable button, make sure it's not a hybrid, some members have made the mistake. If it is a gas LE, check the window sticker to see where it was made, Canada or Japan.

Looks like we still don't know why some have it and some don't. Hybrids obv have it but doesn't have the disable button because it defeats the purpose. Anyone know why some gas models have it and some dont? I hate staring at empty buttons/panels as well, cheapens the awesome look of the dash.

Thanks!!

I think most people donít like the automatic stop and start (as&s) feature because of what it does and not because of the presence and aesthetics of a dummy button on the dashboard.

as&s shuts off the engine to save gas depending on certain conditions when you come to a stop. The engine automatically restarts when you step back on the gas pedal. Some claim as&s will wear out the starter and battery sooner leading to costly repairs and negate any gas money saved.

I suspect all U.S. 2019 RAV4 gas models have the as&s featureís wiring and not just the LE model. For the non-LE models, the final connection between the wiring and the dash button to activate the as&s just wasnít done.

What was Toyota thinking? I donít know. Iíll hazard a few guesses though. Maybe Toyota wanted to test the as&s feature to judge consumer reaction before placing it on all the RAV4 models? Maybe the non-LE models will have as&s activated for them in 2020? Maybe the as&s feature is only a stop gap temporary feature that Toyota will replace with something else in the near future?

The only other gas saving feature that I know of is being used by Mazda and some other auto makers. Itís called cylinder deactivation (cd). With cd, half of the engineís cylinders get deactivated to save gas but the engine continues to run unlike as&s in which the engine shuts off completely.
