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.

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

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.

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.

It's a safety feature alright, and I'm sure they did extensive research to decide on choosing pressing clutch as a requisite start to machine, still my instinct tells me, the brake pedal is a better choice if we talk of safety

Then you won't be able to push start an MT vehicle.

the brake pedal is the better choice to step on, when starting an automatic.
when starting a MT, stepping on the brake pedal will still result in a rude shaking up, if the trans was in gear when the starter is activated. this will not happen, if it were the clutch pedal that was stepped on.
in either case, pulling on the handbrake before starting, is always a good move.
and yes, vehicles without a functioning handbrake should not be given permission to use public roads.

Passing LTO driving exam does not warrant safety over the basic operating principle of the car because technology evolves rapidly.

By reading the user manual before operating the machine, the manufacturer guarantees safety and functionality iff followed correctly. Ignorance and negligence by the operator is beyond the manufacturer's responsibility.

[dr. d]

what i do is to look for the specific topic in the booklet, and limit my readings to that couple of pages only.
some owners are not lucky. their used cars came without that owner's manual.

there is value to listening intelligently to the driving school's lecture series.
but it is not easy, because the pupils therein aren't yet versed with their cars and the road rules, and probably do not know what the lecturer is talking about, because they can't connect...
