Do you use the "auto-throttle" feature?
2 2

27 posts in this topic

I wonder if I should be using what I call the "auto-throttle feature", which is - when I start releasing the clutch, the car automatically increases revs, as if I'm pushing the gas pedal a little bit, but I'm not. So, when stationary, if I release the clutch gently, car will accelerate and not stall. You could also call it "one pedal take off" :) Not sure if it has official name..

I assume this is a feature to help ladies or inexperienced drivers not to stall the car when taking off.

Do you use this feature? Is it good to rely on it?

1.2 tce manual here, but I assume diesels are like this too.

I think there's something more that is added for this feature to work - I have a Peugeot 207 diesel, 2012, which has ecu controlled fueling but it doesn't work there. It will start stalling if I'm releasing the clutch - even if released very gently - without applying the appropriate revs.

I've only had the chance to try a Captur diesel and it also had this feature. Haven't seen it anywhere else.

I agree about clutch slipping - that was my main concern - obviously don't want to wear out the clutch too soon by using it this way on regular basis.

If this is a "Feature", then they didn't put it on our 1.2 manual Kadjar! In a previous post I mentioned taking 3 dabs of the clutch to get it moving on a gentle hill; I've now [after 5 months] got it down to two: one to release the auto-handbrake, the second to get the car going. The Bite-Point on the clutch on ours is set really high, maybe it needs adjusting?

Have you tried releasing the clutch slowly? Does your car stall then, instead of automatically adjusting RPMs accordingly until it takes off? Its what happens on mine - I can basically take off by just releasing the clutch a bit slower than usual. Its mostly useful on level or down hill roads, as up hill it feels like the car is not applying enough power to actually start moving and will eventually die (never pushed it that far though).

Clutch bite point on mine is also very high - almost at the point of fully releasing it, so for what I can tell thats normal. I believe its so by design. As on mine the point where the car starts to automatically power itself is from the very lower point of the clutch - just when I start releasing. So I'd say the car (or ecu) knows that you're releasing early on. 

Why don't you release the hand brake manually (with the button) instead of using the auto-handbrake feature? This might be the reason you haven't noticed the auto-throttling :) as you're always on hand brake when taking off. Maybe try that? And it will also save you the extra dab.

Thanks for that, good to know the clutch-position is typical. I must have tried slow-release, it seems I had to learn all over again; don't want to rev-it-silly to set off. I had a 2L 130 HP diesel Zafira with auto handbrake that you just drove away, probably this 1.2L petrol hasn't enough grunt at low revs for that. I'll try releasing the handbrake first, and if it makes life easier I'll persevere. Seems a bit silly to have an auto-feature that works best manually though LoL! One of the downsides of having a tiny petrol engine perhaps; but I'm happy with the way it warms-up quickly and steers well cos of the light-weight in the nose.

You should not have to release the handbrake manually! I have no issues with my 1.2L manual Kadjar when taking off up hills or on the flat and no need to rev it silly. Smooth as silk. Confirm the high bite point for the clutch, it was like that on my previous Scenic too. You'll probably get used to it all, eventually.

Exactly the same with my 1.5Dci manual . No need for any "special " techniques just drive as I was taught many moons ago :D

Thanks Guys, I suppose years of learning with low-power motors [1.1L Escort, 1.3L Marina... ] comes to nought and I need to go back to school. Going to cover my inadequacies and buy an auto next time, or perhaps the 1.6 petrol. Or maybe the wife will trade me in for a newer model...

Just to clarify , I found no lurching of the car when allowing the hand brake to release automatically , it operated as smoothly as my previous Scenics had . Living in a a hilly area ,I found it best to use it that way . Manually switching the hand brake off would cause the car to roll back  unless I "held " the car in gear , which is a no no for the clutch

Actually its quite the opposite - you can't manually disengage the handbrake unless you're pressing the foot brake - the car wont allow you. So there's zero clutch pressure when releasing hand brake manually as opposed to releasing it automatically, when its actually being released due to the clutch starting to slip. 

The way I see it both features (auto-throttling and auto-handbrake) are not to be used on each and every start, but are there to help just in case you either miss to apply enough revs, or to release the hand brake manually (which is preferred on my opinion).

Odd that , I could manually release the handbrake at any time . Maybe because I always put the car in neutral when stationary ?

You sure about that? If I push the hand brake button without applying foot brake the Kadjar wont release the hand brake and will alert on the dash "Apply foot brake first" or similar. Its a safety feature - they don't want you to accidentally release hand brake and roll down hill.

You may have the warning but you can still release the hand brake . As I said , I usually leave the handbrake do it's thing and put the car in neutral . Stopping the car on a hill without applying any form of brake would be just plain stupid :) .I'm driving an automatic now and I always use the foot brake when stationary , hand brake only used when parking

I can't - when the warning appears the hand brake is not released. Its mandatory that I press foot brake first. At least with manual gears it is so.

Yes, you can't. Same with mine. Boyko is correct. Unless it's different in different regions or different releases. For example a guy complained in our local forum, that his daytime light stops when a blinker is operating. It appears, the new releases of the Kadjars are made this way.

Maybe it's because mine was an October 2015 model ? I haven't driven it for more than a year so I can't pop out and double check  :)

Mine is from October 2017 and I can't release the hand brake without pressing the brake pedal. Tried pressing it multiple times or keeping it pressed. 

The daytime light stay on while blinkers are operating in my car.

Well again, I've never (in the 11 months I've had it) had an issue of any kind with the automatic handbrake  when taking off quickly or slowly, on the flat or on a hill, in busy car parks or on my driveway, in forward or reverse.  I'm baffled by some saying they sometimes need to control the handbrake manually.

There is a slight delay though when waiting for it to apply when stopping at say uphill traffic lights,. then it suddenly bites and can cause a jerk if the car isn't 100% stationary - but I avoid that by applying the footbrake for a second or two as I come to a halt.

There is definitely less fine control with these electronic handbrakes though, compared to manual ones, and when I first encountered one on my previous car a Scenic over 10 years ago, I HATED them with a passion. Maybe I get on fine with them now because of that decade of practice! ;)

Same here Dave, I've never had an issue with it. My first car with auto handbrake and I love it.  On the occasions when auto stop isn't available  I apply it manually. Driving away has always been problemless. I drove my mate's car the other day which hasn't got this feature and I forgot that I had to manually release the handbrake, stalled it twice.

This guy's car is brand new. January 2018 if I'm rught....

Who's that? Mine is one of the very first / oldest in BG - November 2015.

I have no issues with auto handbrake releasing - its smooth. But I'm still not using it. I prefer to operate it manually with the button, at least for releasing - applying is by itself when I turn off the engine. So I just suggested that @Johnbridge may release it manually too. Its a preference thing :)

I might try the manual release, just to see the Boyko-Boost, sorry Auto-Throttle at work!

I advice against using the auto-throttle regularly as I'm having clutch issues which may - or may not - be related to it.

As for handbrake - auto or manual release should be as per your personal preference :)
