Thank you!
20-21 Automatic Engine Shut Off Feature
- Thread starter Saker
- Start date
Thank you!
i remember now when i went camping last july. i needed the internet for my daughter to work on her school work so i just switched it in acc mode for maybe more than 1 hour. so far it did not shutdown. i have a sr5 with the real key. it could be different on push button start 4runners.
I do all the time
I do all the time at work, sometimes my job involves monitoring work on large construction projects or landfills. We run the vechicles all day with the AC cranked or heat in winter.

FWIW - idle time is not good for engines. On my F250 it has an idle meter that you don't see. But it's counting. Ford says all of the following are equivalent: 5,000 miles of driving, 200hrs of idle, 350 gallons of fuel burn, or 3 months of time. For commercial service, the first to be reached is time for an oil changed. That translates to 1hr of idle time equaling 25 miles of driving.
There are some other studies that show idle time on newer engines is actually worse than highway driving. Some wear comparisons showed 1hr of idle time does more wear than 120 miles of highway driving. The reasons are complicated, but they basically are the result of inefficient fuel burn leaving residue on cylinder walls that reduces lubrication and more blow by from lower compression and heat not sealing the piston rings to the cyl walls well. So long idle times are not good for modern engines. Even warming up for more than a minute or two ("dozens of seconds" is what Toyota says) will cause more engine wear than driving.
I get that idling happens and is part of normal use. But extended idle times should be accounted for when thinking about maintenance. If you're idling a lot - I'd change to 5k mile oil changes. If you're idling all day like a service truck might - I'd change the oil ever 2-3 months regardless of miles.
Also - just one crazy point of reference - my F250 was from an oil field service company. It had only 105k miles on it. But it has 17,000 idle hours on the counter. So that's roughly the equivalent of 500k miles of engine wear! That's why ex fleet trucks are something to be cautious of. And it's why mine needed a cat and EGR system cleaning at relatively low odo miles.

Lately, like when I was waiting in line at Costco for gasoline Ive been shutting off my engine instead of idling. I wish my 4R had the automatic engine shutoff/restart feature to save some fuel. My wife’s 2018 TXL has it. Thats a big car with AWD and it gets “great” fuel economy. On the highway it will get 32mpg.
Well, if you look at the 4Runner on one end of a spectrum, and these 32mpg unibody SUVs on the other, the only significant point in between would be the newest Ford trucks around 25-26 mpg, in my opinion.
And to do that, Ford uses metals that are extremely expensive to replace, and tiny turbo engines.
Now, whether or not 4Runner type customers wouldn’t want expensive panels and tiny turbo engines is a question I can’t answer, but my hunch is that they would not. I do not.
The Japanese makers are having very interesting reactions to the EV craze and everything that is going on with it. They’re kinda all over the place. My point is that it’s hard to tell right now where they’re going, whereas with US makers we all know we’ll it’s going to EV as quickly as possible.
Mazda is really bucking the trend. They’re about to release a new line of straight 6 engines, including a diesel version and a hybrid version, that will be mounted longitudinally like a real performance car. The new engines are going in cars and even SUVs, which should be crazy interesting and compete directly with BMW on all fronts. Mazda is literally going backwards, back to a previous era of developing internal combustion engines and going away from EV as a brand. If you know anything about watches, I liken this to Mazda being like the Swiss and digging their heels in. Not out of surprise or ignorance, but more to have something special that enthusiasts will be able to love in the face of an EV industry that “has less soul”, if that makes sense.
All this said, it’s a very interesting question: what will my Japanese car be like in 5-10 years. Only a few cars do we know the answer right now. Personally I hope Toyota keeps the 4Runner “relatively ancient” and bullet proof with older tech like we have now. It could stand improvements, but keep it simple, rugged, and slightly overbuilt. I think economy could go up to 24-25 mpg, but I would not hope for more yet or the 4Runner is possibly ruined.

Laugh all you want. After hurricane Sandy the inverter in my Limited plus a 100’ extension cord gave me lights, tv and a heated mattress pad for almost two months! I did have to run downstairs every now and then to turn it all back on though

Not laughing but actually disappointed I didn’t get to buy one of these before my Chevy Volt got totaled with precisely zero body damage.

That is correct.
It happened to me without doing either or touching the brake pedal.
That is a feature that was not on my 2014, IIRC.

Few days a week I pick up my younger son in car line. I can choose to show up closer to actual dismissal time, then suffer through the stop and go slow roll through the parking lot, or I can get here a bit on the early side with my laptop and actually get work done. If it’s 80+ and sunny, or raining, you better believe I’m idling with the A/C on.
First time this happened to me in my ‘22 I wasn’t sure what to think. Later looked it up in manual and realized I can avoid it by shifting out of P and back after a while.
