Hill-Start Roll-Back

[Neopyrrhus]

Hi there, I've just realised that my 1995 GS300 rolls back if I try to do a hill start on a steep hill. Is this a fault? I assumed that all automatics have anti roll-back systems when in Drive Mode? Of course on a shallow hill the normal forward creep holds the car, but if its a fair incline its too much and the car rolls back. Any advice?

I think mine does if its really steep as well.

The newer Lexus cars do have a feature to help with hill starts, but it doesn't work every time and not sure if the older ones had it. Having said that it depends on the steepness of the hill as well, our 2005 Merc even will roll backwards (or forwards when in reverse) if the hill is a bit steep.

I'm not positive, but I think on mine if I am moving up an incline and come to a complete halt on that incline, then the car will hold. If I am parked up and start the car on that incline, I think it would roll back. Don't quote me on that though.

The only odd thing I find, is in the first scenario where I have come to a halt, if I have the aircon on and the compressor kicks in and the revs rise slightly, the car will actually move forward slowly, which can come as a bit of a surprise.

This is a fault and should be fixed immediately by a main dealership

No it isn't. It is normal for that vehicle on a steep incline.

the 96 gs i had just had the standerd auto creep which held it from rolling back, my new 450 has anti roll back it feels different
