Start/Stop behaviour contrary to owners manual
 

In the manual it says engine won't auto stop if not up to normal operating temperature and also on autos not until gearbox is at normal operating temp.

Mine stops way before this. First traffic lights on my work commute are only 2 or 3 mins away from home and if I forget to turn the stupid thing off it stalls the car at that point.

Anyone else see this behaviour from their start/stop? Car is a 65 plate XC60 D5.

I don’t see it as I instinctively turn the damn thing off immediately after starting.

if you monitor the coolant temp via the OBD port you will see they warm up incredibly fast.
does the engine stall you say or stop/start stops it?

Mine used to do it as well, I quite liked the stop start if I'm honest, it however wouldn't always do it like that, I think iirc there are various things that can stop it like the battery condition, outside temps, low fuel and a few others I can't remember right now,

The thing that did annoy me though was if you slightly reduce brake pressure it would fire back up, however it also worked out the other way round where I could roll up to the blockage using gentle braking and not need to even let it stop if I balanced the pressure right so she wouldn't crawl but I also didn't have full pedal down at the time, works a treat for wanting to get onto a roundabout or out of a side road and not have that mental lag waiting for the fire up.

Start stop stops it. No way it's up to temp after 3mins takes about 10mins to get to 85-90 degrees coolant temp.. I have monitored it. The dash indicator goes to normal position after 5-8 mins but real normal is 85-90C and that takes 9 or 10 mins even at this time of year.

May be normal behaviour but It's not what the manual says.

My previous V50 would shut off less than a mile from starting! It also had an incredibly slow warm up time so I doubt the coolant had much heat in it. The XC60 certainly warms up much faster but I'm still not happy with it shutting off so soon when the oil will still be quite cold.

I tend to turn off the feature unless I know the traffic light sequence so am sure I'll have a long wait

Ok thanks so it's not just mine doing this before engine has heated up and I now know I don't have a fault somewhere. Well other than than the designed in fault from Volvo stopping and starting cold engines that is!

Mine does this aswell within 50 yards of a cold startup and then like you I turn it off . In my opinion as long as the battery state of charge is above 80% the stop start will work even with a cold engine . It is a very poorly thought out system on an auto .

Yes and contrary to what the Volvo manual says should happen, it states start stop will not operate if...

> the engine does not have normal operating temperature. (M+A)
> the gearbox does not have normal operating temperature. (A)

Yes, this is my experience too (V60CC D4AWD). I have a junction half a mile from home, it always stops the engine, and there's no way it is up to temp.

Also, why does it need the footbrake applied? Why can't it work with the parking brake applied? According to the manual, it will restart if you release the footbrake, which means stopping at junctions with your foot on the brake rather than using the parking brake. That's not good practice.

It's nothing to worry about engine wise as the oil will be up to pressure and circulated fully by the time junction one arrives, it's an annoyance for those that dislike the function more than anything, personally I liked it, I didn't think I would having listened to others who've had it in the past but the serenity in addition to the smell of nearby Lavender really zoned me out into a calming alternative reality until trying to find a parking space brought me back to this reality, oh well it was nice while it lasted. :D

I like it on balance, but it does have its irritating aspects. I try to manage the energy when I drive, so minimise wasteful braking - a bit of anticipation for slowing down, and so-on, without inconveniencing other road users, obvs. That quite often means I approach a queue and come to a halt and immediately set off again. The car stops, coughs, restarts and off we go. It's not a problem, just a minor interruption to the smooth progress that would have happened without the stop-start. And, as I mentioned upthread, I don't like the idea of dazzling the car behind with my brake lights, just so I can use the stop-start system.

This is every single car I've driven with stop/start not just Volvo

I think the whole idea is case of ; just because you can, doesn’t mean you should!

I always switch mine off, press start, press disable, automatically.👍

Not saying I agree with it or that it's how it should be.

Personally my stop/start doesn't kick in very often but the first time it does I disable it. One advantage of having two dashcams with parking mode enabled

I really dont get the hate for stop-start

Not in my other car, a Tiguan. You brake with the foot pedal, when stopped the engine stops (and unlike the XC60, it waits a second or so, which I do prefer as it avoids that constant cutting-out in stop/start traffic). The hand brake automatically engages and you can take your foot off the brake pedal without the engine restarting - engine restarts when you touch the accelerator (or, if you have adaptive cruise control, which I do in that car, it starts when the car in front moves off).

It's definitely better than the volvo approach.

Aha, I've never had a car with an auto handbrake

I can see why Volvo don't do it that way . what if a pedestrian runs through the gap just as the stop start comes in and it pulls away? Does it have pedestrian detection ?

Car doesn't drive off automatically - it's just that the engine starts when the car in front moves off. Driver can either then touch the CC resume button, or use the accelerator. As I said, it works very well.

I had that in my 2015 Passat, worked perfectly.

when i stopped the brakes would essentially 'auto hold' and the brake indicator in the dash would go orange and it released when you went to move off.

if you manually set the handbrake the indicator would go red.

the only minor thing i found is when the brakes held the brake lights stayed on, which i imagine would annoy cars behind, when the handbrake was manually st they didnt
