Aurion HandBreak/Auto Hold

[RoadRunner]

Hey guys, hope you are all well and had a great Christmas.

I am having an issue with the auto hold when on steep inclines sometimes when i take

my foot on the brake and go to accelerate in rolls back and does not hold and which

results in the traction control kicking in and than it goes.

It does not do it all the time only on real steep hills, does the brake need to be adjusted or is this a more serious underlining problem.

I should not have to but the " Hand Brake " on or am i doing it wrong? this is my first car with such a feature so i am not sure.

p.s: as always i did a search first but could not find an answer.

Hope you all have a good new year, AJ

As far as I know there is no auto hold feature on the Aurion

When you stop on a hill or incline and then take your foot off the brake it holds it there, might not be called auto hold but i did not what else to call it.

Do you engage the handbrake?

Left foot brake, problem solved.

Mate after reading this this morning I gave mine a try on a real steep hill and found the car started to roll back .So it proves the auto hold does'nt exist on the Aurion It wont roll on a flat surface and if you rev her slightly it would hold using revs and gear box .Thats why we use the left foot with a Auto

All automatics have some amount of hill-holding ability due to the torque converter not being able to 100% disconnect in drive - this is why the car can inch forwards on level ground without the accelerator. Exact same thing as slipping the clutch in a manual to hold it on a hill. This is not a "feature", simply a characteristic of a torque-converter automatic transmission.

Auto-hold/hill-hold as a designed "feature" is usually implemented as extra valving in the brake system which keeps the brakes applied on a hill until a certain amount of throttle is applied (or the clutch released enough etc) - it has nothing to do with the transmission at all. It is also usually found on 4WDs, often bundled in with a hill-descent control to keep at a crawl speed going down hill when off-roading.

Thanks for all the help and reply's in means a lot so it seems that i would have to keep my left foot on the brake and rev it a little and than go. So if i was to do a hill start how would it be better to use the hand brake as it will or foot brake?

Foot-operated parking brakes (which the Aurion has instead of a traditional handbrake) have almost no modulation and are useless for hill-starts - just learn to either left-foot-brake or heel-and-toe.

Seems i will have to put how would you get the parking brake off and than foot on brake?

Edit: i should go to my local toyota dealer and ask, wonder what the response would be!

?? I don't understand what you are trying to say...

The foot-operated parking brake (ie the "third pedal" in an Aurion) is used for parking only. When you are driving around and need to do a hill-start (that would normally require the use of a traditional handbrake), either keep your left foot on the brake pedal and accelerate a little with your right before lifting off the brake (aka left-foot-braking), or push the brake pedal with the ball/big-toe of your right foot and accelerate with the outside of your right foot (heel-and-toe, although you don't really use your heel any more).

If you're stopped/parked and need to do a hill-start, then hold the brake with your right foot whilst you deactivate the parking brake with your left. Then shuffle your left foot to the brake pedal (note how it is usually much wider in an auto than a manual) and your right foot to the accelerator.

Or just quickly move from the brake pedal to the accelerator, unless you're trying to drive straight up a cliff you won't slip back too far.

Simple driving techniques.

1) Get in car

2) Apply brake with right foot

3) Start car

4) Keep right foot on brake and release foot brake with left foot

5) Shift car into drive

6) Quickly move right foot from brake to accelerator, or if you can't manage that,

7) Move left foot over to brake pedal and apply pressure, then remove right foot from brake

8) Apply a bit of throttle with right foot then release left foot from brake
