Pressing clutch when starting

[luffin]

Mga sir sinearch ko sa net kung bakit ginagawa to, eto ung mga reason na nahanap ko, pakicorrect na lang po.
1. Para hindi umabante kung sakaling nakagear (obvious naman to).
2. Some cars have clutch safety switch, kailangan talagang ipress ang clutch para mastart.
3. Less strain sa starter.

May nagsabi naman na pag pinress mo ang clutch bago ka magstart may added stress sa crankshaft thrust bearings, specially pag cold engine.

Anu po ang totoo jan? Thanks

Iwas kadyot.

Just for the reasons you stated in #1 and #2.

It's just a safety feature. Iwas SUA.

I experienced this with my brother's car. I was wondering why it wouldn't start until he told me that I needed to depress the clutch pedal. He also showed me that it has an indicator.

I'm interested with this, why require the clutch pedal to be depressed before starting?

Been a while since I've driven a manual hehe. My dad also taught me that. Press on the clutch para iwas kadyot. I remember my ex would always get mad at me for this. I would sometimes drive her car. So when I park her car, I put the gear in 1st gear when I turn it off. She naman, was taught not to press on the clutch when starting the car. So palaging nag kadyot yung car niya when she starts it (after I park it) hehe.

Yes, it's an added precaution to ensure the gears won't engage when you start your vehicle.

The clutch is a mechanical switch that connects your wheels to the engine so it's purely mechanical not electrical

Walang silbi yan pag tapak mo sa clutch kung hindi mo din nilagay sa neutral yung kambyo.. kasi pag start mo for sure iaangat mo yung paa mo so kakadyot ka din...

Best practice pa din mag triple check kung naka neutral ka then press the brakes together with the clutch

Not a mechanical interlock, its actually an electrical switch just like the brake light switch under the pedal connected to the ECM that controls the IPDM and ignition switch. Depressing the pedal turns it to on position, a logic state needed to turn the starter. On most AT's you won't be able to start the engine without depressing the brake, these are some of safety features and written on the user manual.

to prevent surprise surge in case the car is in gear.
it's a precaution designed to take advantage of existing habits of owners of older cars that do not have "kadyot precautions". so as not to force old dogs to learn new tricks.
my opinion.

I personally do not press the clutch when I start my car. I just wiggle the stick shift before I put my key in, Put the key in RUN position, wiggle the stick shift once again just to be sure it's in neutral, then start my car. I believe that pressing the clutch when you start will just give the clutch extra unnecessary wear (That's what I believe haha I may be wrong). This has become a habit already, even though I drive our A/T car, I still tend to wiggle the shift lever, force of habit

Speaking of which, is there any aftermarket safety device available that we can install in old school cars? Para iwas kadyot din hehe. Parang okay din mag-install in my 96 Corolla.

meron kung meron. pasadya.
it's a simple mechanical switch that interrupts and connects the starter relay circuit.
it can be installed above the clutch pedal, the way some brake switches are strategically installed atop the brake pedal.
the difficult part would be fabricating a "holder" for the switch, to anchor it in the correct position.

Electronic brake & clutch switches, I think, are Hall Effect Sensor type.

but my design above not electronic. it is simple electromechanical. no electronics.

I prefer your D effect switch, too.[emoji106]

thank you.
i like it, too.
but i am still thinking it over, on how it might affect push-starting.

Hall Effect will just be more reliable w/o mechanical parts. It functions as a proximity sensor...& I've push-started those with the switch. Yours won't be any different & will work.... as the safety only cuts power to the starter, not the ignition system.

I read my Suzuki Ertiga's Owner's Manual and it instructs the user to push the clutch (while on neutral) before starting the engine. I have been doing that for four years and I think it's safe for the car since it's in the user's manual.

Although not everyone at the casa does that.

Thank you very much.

I grew up in a generation where we're taught to check and make sure that the stick is in neutral position before starting the engine. Never taught to step on the clutch pedal before starting. Now, I've never driven a modern manual... at least none of the M/T cars I've driven required the driver to press the clutch before starting, I do understand the concept behind the practice. It's just sheer force of habit to me not to step on the clutch once I'm sure the stick is in neutral.

That said, what can be your last defense would be the handbrake. Having the handbrake properly engaged would prevent the vehicle from surging, in case it was started while in gear. Make sure it's engaged all the time up until the moment you're about to drive away.

Bottom line, if your car came with this safety feature, use it. DON'T defeat it. If your car didn't come with it, chances are, you already have the muscle memory to do your safety checks before starting the vehicle.

Retrofitting this safety feature on a vehicle that doesn't have it is not a bad idea. However, it does take some skills and is not for everyone to do.
