Maybe that's what they mean and have got their phrasing wrong.
Pressing the footbrake doesn't release the AH, pressing the accelerator does.
Don't mean to be argumentative, but this is what manual states and pressing on brake does also release auto hold (as well as accelerator pedal)

WARNING
To prevent, unexpected and sudden
vehicle movement, ALWAYS press your
foot on the brake pedal to cancel the
Auto Hold before you:
- Drive downhill.
- Drive the vehicle in R (Reverse).
(vehicle equipped with shift button)
- Park the vehicle.

Obviously I don't bother with the handbook - mainly because it's too generic.
Never had to turn it off going downhill before. I see that in the US the latest Santa Fe models have an option to have it always on, which is what I have had in previous cars - not Hyundai - so I don't understand why it needs to be turned off when going downhill.

The UK handbook also states that it should retain the last instruction between journeys but it appears it doesn't do that, but reverts to off between each journey so has to be applied at each start up.

Just read the quote from the book that you posted.
It means that you should put your foot on the brake when on a hill if you're about to switch off AH, otherwise the car will roll on its own.
Don't overthink it, just get some practice.

Yeah, will do. First car to have this on it so all new to me. too busy keeping my hands warm on the heating steering wheel to enjoy anything else. :D

I think it's fair to say that the handbook should be used as guide rather than a Bible.

"the parking brake will automatically engage when you switch off the ignition "

Only if you put it in P (Park) first.

Not if you have AH switched on.
I stop, turn off and the parking brake is automatically applied and it puts the gearbox into Park.

It’s apparent to me from comments I have read in both this forum and the KIA forum I joined in 2016 and of which I remain a member today, that some drivers of cars equipped with Autohold and an EPB have never mastered the skills required to extract the best from the system. Some, indeed, actually choose not to use Autohold and physically apply the EPB at almost every stop situation. Some also select neutral in their automatic/DCT whenever they come to a stop in traffic.

With regard to your point about not understanding the difference, it’s actually very easy to grasp.......Autohold, once selected, is a function that permits the car to be held in any situation, utilising the hydraulic brake circuit. It is the same as sitting at traffic lights or at any other stop situation with your foot on the brake.

The EPB operates on the rear brakes through a physical electro-mechanical arrangement, entirely separate from the hydraulics. The little switch permits, via a gentle, one-finger pull, the EPB to be engaged. It may also be pressed gently downwards to disengage the parking brake.

While driving the car, it is not necessary to physically disengage the EPB before setting off after a stop situation as the slightest application of the accelerator will automatically disengage the EPB. However, for the vast majority of stop situations, it is most practical to come to a halt with the footbrake and allow the car to remain exactly where it is, thanks to the Autohold feature.

There is the odd caveat which needs to be understood; For example, once the car is held stationary by Autohold, the brake lights will be on which isn’t much of a big deal during daylight hours but can be a nuisance in darkness to any following driver. If that is of concern to you, then a gentle lift of the EPB switch will change the arrangement from hydraulic hold to the electro- mechanical parking brake, extinguishing the brake lights.

There are many other beneficial features in our modern cars that some, (mainly the elderly) cannot or will not come to terms with. By way of example, fully synthetic oils were a game-changer when the scientists and chemists developed them many years ago. Even in this 3rd decade of the 21st century, there are still people who imagine that 10,000 miles is far too long between oil changes. Not only are they wrong but they are wasting money as oils (and filters) today are far superior to those of the mid-20th century. Allied to the incredibly improved machining tolerances possible today, there is no need for an early first service to collect and remove swarf or other impurities. It’s probably wise for track cars to have more frequent oil changes but those machines are a world away from our family cars, even the sportiest.

Sadly, it is almost impossible to change the views of the ‘belt & braces’ contingent with their WW2 mentality handed down from fathers and uncles.

Make no mistake though; I don’t subscribe to every element of new tech in our cars. Steering is something I want to control all the time I’m driving so I don’t make use of LDW, LKA, LFA or any other artificial assistance. Fortunately, for the present, there exists the means by which I can disable those aids. I doubt very much that I will be around to see mostly driverless cars on our roads but I have no doubt that the technology is there already and we are being gently introduced to it by the addition of these ‘driver aids’ now so that we become accustomed to their use.

Thanks Indalo, a very detailed and comprehensive explanation. I’ve been out today, and now knowing the benefits have used the AH and agree it is a decent system. I’m not that ‘old’ to be changed I just didn’t realise how useful it can be, and when getting a new car there are a thousand and one things to work out etc and the AH was maybe further down my list of priorities than it should have been, hence why I have been looking in to it today some 3 weeks after getting the car. Now I know what it does and the benefits I will switch in every journey. I remember when EPB first came out is was sceptical but soon came round to see the benefits. Anyway thanks again for the detailed response.
