Push Button Start

[FLSteve]

I have never had the push button start feature on a motorhome and was just wondering how it worked. With the key start you have time to let the engine warm up light go out before starting it. How does this work on the push button start?

Are you talking diesel?
I installed push button start on my 1999 gas Dutch Star. Works great.

 

[FLSteve]

Yes … I meant to say diesel.

 

[Russsilber90]

Okay, sorry can't answer that.

I'd assume it won't crank until it's ready. That's what my ram would do when I'd jump in it and try to crank immediately forgetting I got in the diesel truck instead of the gas truck.

A month or 2 after selling the ram I'll get in the gas silverado and turn the key and wait, forgetting I don't need to.

My ram has push button start with a cummins diesel. Today I pushed to start and the display said preheating engine and a countdown started. At zero it auto started.

When it's warmer, it just starts right away.

We have the push button start on ours. I used it once just to see if it worked. Call me old school but I just don't see the point. I have electronic trust issues. Been around it too long and seen too many failures.

If you have push button start, then that is the only way to start the vehicle. The Push-to-Start system replaces a traditional key.

This is not the same as keyfob remote start.

Actually, there is a start button on the dash and a key switch. You have to have a fob in the driver proximity for it to work.

This is something that must have been added after the fact. No NEWMAR coach comes from the factory that way. You might want to check the service history on your coach, as this is not right.

I just realized the confusion I had with @Dona40 . The coach they own is not a newmar, which I assumed it was since we where discussing a newmar motorhome push to start operation. I guess THOR uses both systems.

If my coach had both systems, I would not see the point of the push to start either.

 

[Dona40]

Yeah, our DX40 came from the factory that way. They advertised the first coach with that feature. I say big deal I was just commenting on the system itself.

I haven't had a diesel with push to start...got me thinking....on my Escalade, one puts their foot on the brake, then pushes the Start button and the ECU takes over and starts the engine (gas). So, is the brake requirement also in place for diesels? And...when you push the Start button...does your foot have to remain on the brake until the pre-heater is hot and ready to crank? Or with air brakes...is there a brake push requirement needed at all? Questions, Questions....

The controls that go Digital provide less “feel”. Analog controls provide much more feel.
For instance the 2017 Vw controls the starter and other functions digitally. Once the battery reaches a certain low voltage the starter refuses to energize. No warning, no indication the battery is getting low. Just stops.

Push button things undoubtedly are run by a Chip of sorts.

Not a fan of loosing that “feel” regarding how things operate.

Other than a "key" that is smaller and less pointy to stab you in the pocket, I don't see much value to push to start. It would be a little bit more secure, but thankfully I live in the woods and don't worry too much about theft.
re: more "feel" for the start...the assumption is the vehicle is operating normally / correctly so not a whole lot of value to "feel".
Now if you were talking about autonomous driving vs. conventional...then yeah, lots off difference there.
For the majority who have no idea of how things work, then Push to start is nice...the ECUs are a whole lot smarter than most all drivers and are monitoring just about all the key systems - which all drivers aren't.
