I don't think putting in R or D will work like in a manual car since it is all electronic from my assumption.

Hand brake wasn't disengaged. I unlocked the car and then opened its doors. Just when I was about to get in, the car started rolling, but slow enough so that I could get in. Very strange that the handbrake was not strong enough on a 4-days old car.

I asked them if putting in R or D will make the car act like a manual car with first gear engaged. But they were not sure.

Just when I was about to get back in, the car started rolling and I somehow jumped in and took control. This proves that leaving the car on A/D mode doesn't work like how it works on a manual car with first gear engaged.

This incident has left me scared to the bones and I now park only on level surfaces or on moderate inclines, even it means I have to walk a much farther distance. I am now thinking of getting a wheel stopper, the one which we used on ambassadors / premier padminis.

Don't worry you had not engaged the handbrake fully, or your new car needs to get the handbrake tensioner adjusted.

My driver sometimes doesn't engage the handbrake fully, when he parks my Nano in front of our gate, he has week hands, I told him to give it a good heave to engage,(he now uses both hands to engage) after which no issues.

Consider an AMT a manual with just the shifting automated and hence follow the same practice as you would in a manual. There are 2 AMT's in the family, an Alto & a Tiago and from day 1 we have parked it in D with 1st gear engaged.

Might sound basic, but make sure you shift to D when the ignition is on, so that the actuator has the power to actually engage the gear.

Just handbrakes holding the car is very risky.

Yes, R or D(which is basically 1st gear at standstill) in an AMT is just like a manual car.

Thanks brother. I might have shifted to D after the ignition was OFF, Not sure. I should definitely try it out again, may be in a safer environment. If it worked for you in a Tiago, it should definitely work in my Punch. Thank you.

In AMT, if someone switches of the car while being on "N" and then put R or D, the car will stay in N (even though the gear stick mas moved to R or D).

In that case, should one put in 'M' i.e. the manual mode and put the car in Gear# 1 and then kill engine and will that help?

I would agree on this, slotted in D in my Brother's Celerio in a ramp and switched off, thinking it won't go back, but it did.

As you say, only hand brake stops it.

Own an AMT car and paranoid about rolling back?

Park the car in N and pull the handbrake. Get out and try to push the car a bit to check if it's rolling back so that you are less worried. Place a stopper/blocker behind the rear wheels if need be.

[sagarpadaki]

The owners manual of all AMT cars mention to park in gear, ie, gear lever in 'A' position. Parking an AMT car in N is same as parking a manual car in 'N'. Expect same behavior. Ideally, the handbrake must be able to the hold back the car on its own. The handbrake mechanism at the rear wheel has toothed adjusters which determine the handbrake pressure that can be applied. The service center must be able to adjust that so that the car can hold still just on the handbrake even on an incline.

Thank you for this piece of information. I find the hand brake in our new Tiago (manual) a bit weak compared to our previous car (i10). Good to know that something can be done about it .

Both are parked in N with handbrake fully engaged, (as per the manual) and mind you both parking areas are at a slight incline, and never ever have they moved from their parked places.

Quoting my own quote,. No issues while parking in N, for both my AMT car's.

The manual says to park in N mode only

Get the adjustment done and do let us know.

I have Tata Zest XMA which is Diesel AMT. I was always skeptical about handbrake being effective enough to arrest any movement of car while parked.Thanks to TBHP, I learnt the perfect technique.
1. When you want to park , shift to A mode ( or D in few cars) .Ensure you see first Gear in MID gear indicator display.
2. Switch off the ignition.
3. Apply handbrake.

If you kill the engine while being in Neutral and then shift to A or D, it is of no use, car would be in neutral.

Assuming one parks the AMT vehicle in-gear or D/A, won't the vehicle de-clutch as soon as the driver puts the key in? It is like trying to push start an AMT vehicle , the clutch does not seem to be engaged in D mode unless the engine is on.

Nevertheless, it would be good to adjust the handbrake on all AMTs during every service. You cannot rely on the gearbox to hold the car in place.

As PSG has pointed out as well, put in D and then kill the engine. That will hold the gear. You can use Manual mode as well.

The whole point is that AMT transmission requires electronic intervention to shift gears, which requires the car battery to be supplying power.

Hi - I had a bad experience today. I parked my wife's AMT Dzire in D mode. I did not apply the hand brake. Surprisingly after about 20 minutes the car rolled down the ramp of our garage and there was severe damage to the bumper of the car. Thank God , no one was injured. I always thought that putting the Car on D mode was equivalent to slotting the car on to a gear in a manual car.

Is my thinking flawed ?
