Is the S/S not like any other car I have driven where you just press the button and it disables it until the next time you start the car? Or do you have to press it repeatedly or something?

Mine does also have the button you’re talking about to disable it completely. But you have to push it everytime you drive the car.

Whenever the car is OFF and you start the engine THEN you have to push the disable button for auto S/S. When you shut off the engine it automatically turns the auto S/S back on...so when you restart the RAV you have to again press the disable button. It becomes a real annoyance when you are making several quick stops like for deliveries.

So its like every rental I have driven. By trip 3 I start the car and press the button. It becomes almost habit. For deliveries I can understand the annoyance.

Thanks for clarifying. Wouldn't bother me too much then. I suppose I would wear that button out eventually

i do not like the grinding on the starter on any of the cars and trucks at the stop lights...
standard starters have a defined life...

what happened to the idea of the inverter starting the ICE?
they were working on a 300+volt starter that was just a winding.
the reverse of the brake regen system.
they were working on decompression spin up on the ICE.

it may still be in engineering and development stage.
they were thinking 2024 would have it but that was
before the pandemic.
so it maybe be pushed back a few years.

I find it hilarious that the 2024 LE/XLE have the same MPG ratings as the Limited but the Limited doesn't have start/stop. Such a ridiculous feature that causes nothing but more cost upfront (more expensive battery and starter) and more/higher repair costs in the long run. Not to mention the ensuing damage and liability when you try to turn into busy traffic and that hesitation bites you in the butt because you forgot to turn off the start/stop. Government meddling at its finest.

It does becomes a habit. Yet if I became flustered during the day I occasionally forgot to push it.Then it would silently shut off the car at a stop light...you would only notice it if you happened to glance at the tach and saw it was at 0 RPMs. When the RAV turned on when you stepped on the gas it did so with a thump and shake that was startling and alarming to me and my wife. I was really happy to discover how to PERMANENTLY disable the auto S/S on this forum.

I saw somewhere that if you disconnect a wire by the hood latch it will disable the s/s function, but, it will show an occasional code on the dash. Further research needed.

Don't know whether this is a violation of the forum but I saw somewhere that if you disconnect a wire by the hood latch it will disable the s/s function, but, it will show an occasional code on the dash. Further research needed.

Here's what to do on 2019-2021 models. There will be NO DTC code. The MID auto S/S disabled notification can be easily removed with the steering wheel buttons.

The start/stop function is only on the ICE vehicles, not the hybrids. Thus this thread is about only the ICE vehicles. There is no inverter, or a high voltage battery (300+) on the ICE vehicles, only the 12 volt battery.

For the hybrids, the gas engine is started by MG1 using power from the HV battery. The DC to DC converter is in involved in that.

MG1 has three functions:
1. Start the gas engine
2. Select the gear rations for the eCVT
3. Generate electricity for storage in the HV battery. The power for that comes from the ICE, not the wheels (i.e. not regeneration)

Only MG2 and MGR (in the back) can generated electricity from the wheels to store in the HV battery. MG1 cannot (regeneration).

What did your further research find?

On my 2024 XLE, when at a stop, it will tell me to press the brake pedal in more to activate the stop/start. So I am in control of when the engine stops at all times (unless I happen push the brake pedal down more than normal by mistake). If I know it’s going to be a short wait for the light to change, I just don’t allow the engine to stop.

Please explain. So you only press the brake lightly and it won't activate. I don't like the feature because it causes a slight jolt like feeling every time I am at a light.

If you have the auto S/S turned on you can learn to modulate your foot pressure on the brake pedal when you come to a stop so the engine will not shut off--in other words so the Auto S/S doesn't operate. It only shuts down the engine when you press down on the brakes firmly. If you feather foot the brake pedal you can keep the engine running. Of course in many driving situations you won't be able to modulate the pedal pressure...for example, coming to a stop on a hill. If you don't like the auto S/S just try to remember to hit the switch to turn it off EVERY time you start the engine. You CAN delete the auto S/S with easily installed aftermarket gizmos and by disconnecting the hood latch wire on 2019-2021 cars.

I just picked up my 2024 Limited two days ago and it has a start stop button. I have only driven it home from the dealer so I'm not sure if it is always in that mode or not. I'll try it out today, it has an ICE engine.

 

[MarkyRAVE]

I'm not seeing any info that the 24 Rav4 hybrid is Japanese built only. Nor that the stop/start of the ICE has been eliminated.

Hello. Just to let you know, the Toyota RAV4 model is also built in Cambridge, Ontario, Canada. However, the PLUG-IN Hybrid RAV4 does come from Japan exclusively, for some reason. I just bought my 2025 RAV4 XLE Hybrid, and I'm very pleased with it. I like to know what my car's Switch Blanks are for. So far as I can tell, this particular button space is for disabling the Auto Start/Stop function, in the Chinese-market-only Toyota Wildlander (the sister model of the RAV4 there!). Fascinating!

 

[FKHeath]

The blank switch positions are for options on the higher trim levels that may not on the XLE, such as bird eye view, auto high beams, etc. The owners manual should show what they are.

 

[MarkyRAVE]

Thank you for that!

On the RAV4 Prime XSE it has a switch on the right side near the Synch button to turn the 120 volt power receptacle in the cargo area on and off.
