Hi,
I recently got myself a SWIFT LDI. I noticed that in any gear, if I just take my foot off the clutch and do not press the accelerator, the cars till moves forward at a slow speed. Is this normal?

Does this also mean that if i am standing on a climbing slope with engine started, and need to move on, then I can simply take off my foot off the clutch and break, without the worry of the car rolling back?

its normal, in fact, if it doesnt, you should be worried. its a useful feature in traffic.
and yes, the car will climb without use of the accelerator up some serious inclines if the surface is smooth and provides enough traction.

You always should worry about the car rolling back, and be prepared for it. the car wont, not normally, but its best not to get caught out.

Absolutely normal. Enjoy the bumper to bumper traffic.

Go Shipra mall. Park your car there for 3 hours and try again.

Thats like that on most cars, it used to be same on higher cars from Maruti ESTEEM upwards pal. I had this same first time experience on an ESTEEM way back in 2000. But later learnt it to be normal. Enjoy the car pal.

It is so common in diesel cars due to low end torque. Even my Indica DLS used to move on releasing the clutch. Yes, on slopes, it used to be a charm.

its very normal. Once when my friend wanted to drive my car (that time he didnt know how to drive) instructed him not to touch accelerator and made him drive on first gear for couple of minutes without using the accelerator.

All diesels do this. Some of the later petrol mpfis too do this. In petrol, it is just that the idling speed is at a little higher RPM.

This is perfectly normal. No need to worry.

I too had not noticed that without using the accelerator I can move my Swift until recently when a friend informed me about this feature in MPFI vehicles. You put the vehicle in 1st or reverse and lift the foot half way on the clutch. Now use this regularly for getting out of my building parking and also in stop-start traffic !!

Nothing to do with MPFI, my Carb Esteem has it.

With the AC switched on, its more prominent, as the RPM increases.

And I guess it will be there in all cars, because even at idle position the engine does work, and once the gear is engaged and you disengage the clutch, then vehicle is supposed to move.

You can even change the gears, and it actually increases speeds. I have have around 30kmph on 3rd gear, without using accelerator.

On a carb engine?????

Must be set to rev at higher rpms

I at times go around my campus in 2nd gear without using the gas pedal. As you continue upshifting the speed also increases. But then ofcourse I drive a Diesel.

Traction isnt really an issue in this case IMO.
I would say it depends on the torque available from your engine at idle RPM, as well as how low the gearing is. (Not to mention the speed its set to idle at == torque available).

Deisels have much better low-end torque, and hence can lug much better in situations like this.

Also, you need to let go of the clutch fairly slowly to prevent stalling.

Well the MPFI has the advantage of the ECU sensing load and hence accomodating for it (slightly more power without pressing the accelerator).

Yeh its perfectly normal, I remember when my driving school instrutor told me so, I was so surprised.

I thought its just like the bikes whenre to make it move from stationary you need to release the clutch slowly & press the accelerator slowly in a synchronous way.
