Stupid Question
 

Will push starting (rolling start) work with Push to start (ie Limited BRZ)? I will probably opt for the battery warmer. Sometimes in the north east it can get pretty cold and a battery will act dead, but once the temp goes up the battery will test perfectly fine. In my past cars I've only had to roll start once or twice a winter max. Just wondering if it is possible with this ignition system. I am guessing push start button once to get into ACC then roll start...??:iono:

Hmm I would like to know this too.

I read this somewhere, "electronics have nothing to do with it, its the pump location. Yes, certain 60s cars will work."

:iono:

I don't see why not.

Just roll the car in neutral, jump in, clutch in, second gear, hold start button, clutch out then right back in again.

If the car is "ON" it should start up.

I wouldn't count on a push start working. Newer cars are very dependent on the ECU to provide the right conditions to start. Also a battery that won't start the car in the cold is bad even if it tests good when warm. It's just a matter of time before it will start having problems all the time. This will be a new car, with a new battery, it should be at least a few years before you have to worry about any battey problems.

This is a good question. Anyone with a proximity push start know how to get your car into the ON II position without starting your car? You know where you can operate your power windows, ac fan, etc.

Oh to the OP, welcome. Glad you decided to make a new thread that's worthwhile.

lol he was a prevous senior member who just changed his name...

Explains the lack of noobiness in his post.

In Rhode Island?!? Synthetic oil alone would solve this, unless your battery is old then the obvious thing is to change it.

In push-start cars I've used, it's basically like in any other car. Push the start button twice to get to "On", then push start the car, just like if you turned your key to "On" and then push started it.

I've done it in my Lexus, only to see if it worked. I can't imagine ever having to do this if everything in the car is right, I mean maybe once the car is old and crappy, but in a new(er) car? Doubtful.

If the battery is dead, you can't turn a push start button to "ON" :slap:

I honestly don't see this working. The electronics aren't going to come on just because your pushing it (the car itself), and let the clutch out in a car that can't be turned on without the electrical part (the push button). With a key, you actually have to leave the key switched to the "on" position. You can't do that if you can't "turn" the key to that position when it relies on battery juice.


Meh but then I think, as long as someone is inside holding the button down while you let the clutch out... Then maybeeeeeeee. But the car is probably thinking its "off" the whole time, because it won't let juice feed to the battery while its "off".


Im lost.

You said you've done it in your Lexus, but your Lexus had a working battery. How are you going to push the button twice to get the switch "ON" if the battery were dead??

I think some people are confusing "Push-to-start" with "push starting" which is what the OP was asking about.

Looks like everyone is on the same page to me:iono:

Although I'm still trying to figure out this one:
Also yayforaddsion, a battery can have enough juice to power the accessories but not enough to start an engine.

I think we are all a bit confused now. We need to call "Push-to-start" something else... lol

But imagine if your battery were dead from maybe leaving some lights on in your car, or whatnot, and you have "Push-to-start". How would you "push start" the car if you can't get the "Push-to-start" button into the "ON" position (typically pushing the "Push-to-start" button without your foot on the break will turn it "ON" without starting the engine). How would you get the car started?

It sounds like you guys wanting "Push-to-start", may just need roadside assistance.

It CAN, but if it didn't have enough juice. Like Canibuz said, If its very cold and the battery acted dead. Or if the battery was literally dead from other reasons. Maybe you left ACC on overnight, would you still be able to push start a car with the Push-to-start button :iono:

In that situation, I'd have to defer to someone who has had that experience. I'd guess you'd be SOL.

Maybe instead of investing in a battery warmer get a portable jump stat kit. That way you're not wasting electricity heating a battery all winter for the rare extra cold day you would have a problem.

Would you still be able to even get inside the vehicle? If it's keyless and has no power running to it (I think it takes 9-10 volts or so minimum) how are you going to get the door open?

I know some cars handle this by having a hidden key inside the fob but haven't heard anything like that with the BRZ. I haven't been looking at the push button start too hard because I don't want it on my vehicle but I think if it was addressed I would have read it somewhere already.

When I started this thread I feared it would turn into the "touching" vs "holding" argument on the automatic door unlocking thread :lol:

I have not been the only one to experience this in RI, I know it doesn't get as cold as Canada but it has happened. Who knows maybe everyone in RI is retarded and all left our lights on the day it happened to be -10 outside. I would hope I don't have to worry about this with a new car, but you never know hence why I asked the question. And yes I did change my username!

Guess I will be making a youtube video with the results during the first winter it has to endure!

*Edit* Portable jump start kit sounds smarter, but if the battery is dead how can I "hold" or "touch" the door to get in and release the hood, which exactly what Alias questioned in his post. </endlessloop>

You only need enough juice to get the car to the "On" position, which is considerably less than required to actually start the car.

You are correct though, if you have a completely dead battery, it is not possible at all.

I don't think I've seen a car that didn't have some way to get into the car when the battery is dead. Usually a mechanical key in the fob that can open the driver's door. This is also important if the battery in the smart key fob dies, you can still start the car, but you need to be able to get into the car to do that.

You could also just make sure you have a good battery. I don't think I've had a car fail to start even on -15 degree days in years and that was with a battery that was at least 5 years old.

Synthetic oil is much more stable in varying temperatures. One of the biggest reasons a car doesn't start in the cold, aside from not having a battery that's up to the task, is that the oil is too viscus. Notice that I live in Nova Scotia, ie -10 degs C is pretty common in winter, -25 or even -30 isn't unheard of. I can tell you for certain that a lawn tractor battery will start a 2.0L four banger, that's running synthetic oil, in any of these temperatures. A proper car battery should have zero issues in Rhode Island, unless the battery is dying or the oil is WAY too old. Hense I suggested replacing the battery.

That is an understandable assessment. However, environmental factors aside. I am guessing that if the battery is dead via user error. That the rolling start technique might not actual work with a push start system. This was the theory behind the question I initially asked.

Yeah you need enough juice to get it into the "On" mode. If you can't, you have no hope of push-starting it.
