Ah yes, that old chestnut. It appears that Perodua owners are still pushing their start buttons more than once before actually turning over the engine, despite the national carmaker having already pointed out last year that this was not necessary. The company has now put out another Facebook post called the “Push Start Button Myth,” asking users whether to press the button once or twice.
The answer, as Perodua revealed in the comments, is just once – with the brake pedal depressed, of course – to start the engine immediately.
Where did this “myth” come from? It likely stems from the fact that on older cars (this is way before the advent of keyless entry and start systems), it was customary to turn the key to the accessory position and wait for the warning lights on the instrument cluster to turn off. Only then would users turn the key once more to start the engine. Even Perodua’s own salespeople have been guilty of teaching this to new owners.
The thinking behind this was that the pause before starting would give the car time to prime the fuel pump and run systems checks, ensuring a full and proper startup. There are also theories bandied about that starting the engine immediately would “shock” the electrical system or the engine and damage them – indeed, this was brought up in the comments.
As Perodua has previously explained, modern cars with their more advanced electronics do not work in the same way. When the start button is pressed in these vehicles, the engine isn’t cranked immediately – there is a delay, usually less than a second, for the car to perform its pre-start checks. The various computers are also able to cancel a startup if a critical issue is detected, preventing further damage.
Pressing the start button once to enter accessory mode before properly starting the engine does nothing to protect the car. There’s no harm in doing it, but there’s no benefit either. The same goes to having the air con turned off when starting a car these days – even if it’s been left on, the electronics will delay spinning up the compressor until the engine has already turned over, so there’s no added stress to the electrical system.
