Does this Car Push/Roll Start?

Well, yeah but you can do that just driving it.

Owner's manual should probably discourage that as well.

The point was they don't want you to blame them for screwing it up by push starting it. CYA on their part.

Oh, I know. Just yanking your chain.

Pretty sure the manual says no chains as well actually.

Yeah, but in other cases they just say that. E.g., "Do not adjust the position of the steering wheel, the seat, or the inside or outside rear view mirrors while driving. Doing so may result in a loss of vehicle control that can cause accidents, resulting in death or serious injury."


They could say the same for push-starts, but the say
"Do not pull- or push-start the vehicle as the three-way catalytic onverter may overheat and become a fire hazard"

I think you are confused about the nature of catalytic converter fires. The fires are not in the converters but caused by unburned fuel heating up the convertor and igniting materials outside of the convertor not inside it.
Here:

I can not find one single reference to fires in the convertors anyplace but if you have a link I would like to read about it (it has sparked my curiosity if even possible)


And if I am not mistaken the manual actually does reference not parking where the convertor could ignite materials.

Exactly this, liability, they don't want to be responsible in any way for suggesting that moving the car without steering or engine power is a safe way to start the car with little risk.

I was able to do it on my corolla the engine spins the same direction regardless, but you have to be careful the jerk when the engine kicks in is slightly worse in reverse.

Haha. Funny story I had to do this 2 weeks ago when my car wouldn't start . when my friend was taking pics of my car in a parking garage. Luckily I was facing down so I just threw it into first, popped the clutch and hit the start and it started first try. The pics were worth it.

Another funny story. I knew my battery was getting bad, but I was turning the car in (lease). That battery had finally died after 3 long years in the Arizona heat. Anyway ... the pre-turn lease inspection guy comes over to the house.

He turns on every item ... checking all the stuff without the car running. I'm thinking that when he finally goes to start it .... it probably won't start. He goes to start it .... and it "barely" starts. He didn't say a thing. I passed the inspection.

Here's the funny part. Drove it to the dealership to turn it in. Got my paperwork and watched as the attendants had to push start the car to start it.

Quite possible you are right, but I have already moved to another question.


That is, why push-starting might increase the likelihood of a converter fire (external, internal, whatever). What is different about push starting compared to using the electric starter, that it may cause the converter to overheat.


The manual pretty clearly associates fire danger with push starts, they don't mention loss of control. They warn about loss of control in other scenarios.
