Interesting Discoveries Thread (Good or Bad)

Cruise Control is great on motorways (freeways) and I use it all the time but with city driving where you're stopping and starting a lot the Limiter is better in my opinion because you can accelerate and brake as much as you like, even with foot flat down, and you won't go over the limit. If you go down a hill and the car picks up speed there is a constant 'ping' to let you know you're over the limit you set.

Perhaps only the European models have it.

We don't have it either.

Must be a UK thing! I read somewhere (this was years ago, it can't have improved) that average speed in and around London was 6 MPH. A speed limiter could save your butt and wallet; simple frustration suddenly met by a stretch of open pavement would tempt one too much: the limiter is a self imposed nanny wagging her finger, "No! Behave!"

On the US Stingers, and maybe others, have smart cruise control. I love using it in stop and go traffic as it can follow the car in front and come to a stop and (if longer than 3 seconds at stop) a flick of the resume switch or a tap of the gas pedal and it follows again. Under 3 seconds and it goes on its own. Awesomeness. Maybe that’s why no limiter as you describe?

It would be useful if it didn't leave enough space for anything, including an F350 to cut in front of me after re-starting.. Even on the "shortest" option, it's basically useless for me in rush hour traffic here in NorCal. I'd get 3-5 cars/minute squeezing in front of me.. Tried it a few times, but every time, have to give up on it.

I don't think there's any way they can safely program that feature to be useful in that sort of traffic.

I don't use it in 'gridlock' conditions either, but it works really nicely for me with more normal traffic - even without having to resort to the shortest following distances.

Hence the reason for both. We have Smart Cruise and Speed Limiter in the UK and both have their uses, Smart Cruise on steady moving traffic like motorways and Speed Limiter in Stop/Go slow moving heavy city traffic.

I’ve not experienced that but, maybe I didn’t have an issue. I don’t remember a cut in more than once. More so at speed as I use two boxes.

speed limiter is an EU thing I guess. I have it too. I had it in my civic too, but I would never use it. What if you have to accelerate hard to avoid some thing bad? You can't cause you are limited to the speed you set.

but @Silverfox I know fines for speeding are ridiculous in uk so I guess it's usefull for you. and plus I think it only limits when you have your foot on the accelerator. When you floating it doesn't notice. It's the same with trucks they are limited to ~90km/h but rolling downhill they can be a bit faster before the system notice it.
maybe try to step on the gas on the next big downhill

GT2 only maybe?

 

[Metalmania82]

Also, do we have rear collision warning? As in, something up behind you and the car thinks it will hit you, it will start beeping and flash a message on the dash?

The Limiter is for completely different driving conditions to when you would use the Smart Cruise.

Smart Cruise is no good for urban environments where there are junctions, bends, hazards, etc. where you have to often vary your speed accordingly. If you had nobody in front slowing and speeding up the car would just go at the set speed into bends and junctions which would be quite dangerous. If you were braking frequently for those things then the Smart Cruise would be continually disabling and you would have to enable it again. The Limiter doesn’t automatically disable at all, it is always on, so you drive normally but will not be allowed to exceed the speed set.

I've had this on rental cars in the UK, I figured it was something handy for countering speed cameras..

GT2 or the Drive Wise or whatever it’s called, option with the smart cruise control.

We had a few days of low pressure weather come through which dropped the cold tire pressure in my left front tire. I discovered that the TPMS warning light will not go off unless it thinks you have 35 PSI or more in the tires. (US measurements, sorry, I'm not familiar with the metric or bar equivs gang). 34 isn't good enough.

The way you said that, it sounds like if you go under 35 psi the TPMS stops reading from that wheel. Surely I am not understanding what you mean.

No, I don't think so, I think it's set to trigger the warning at a certain minimum pressure (I was at 29 PSI cold pressure after several days of not driving and the weather), and filling it back up to 34 cold didn't shut it up. The idiot light went off once the tire warmed up and went over 35 PSI. it was definitely reading the pressure because it knew I was at 29 on startup and 34 after I filled up, and then shut off once it hit 35, I just think the warning light trigger in the computer is set to 35psi.

Does that make it any clearer? Apologies if I'm still being obtuse. it makes sense in my head, but that doesn't always translate from "me" to "human beings".

 

[SteveCo]

There is definitely a 'low limit', several pounds below the recommended (sticker) pressure, that triggers the low tire alarm when the pressure drops below that. Once the alarm has been triggered, to clear it (in my case) just adding a few pounds won't do - the tire has to be filled back to the sticker pressure for that axle. It also has to be driven for a certain period, with the pressure at or above that value, before the alarm clears.

If you want to clear the alarm more quickly, fill it cold to a couple of pounds above the sticker pressure, drive until the warning goes out, then later reduce the (cold) pressure to the sticker pressure.

Because the recommended pressures differ substantially between 18 and 19 inch, RWD and AWD, I'm thinking these trigger and reset values must be specific to the factory supplied vehicle configuration.

My other car uses an earlier type of system where the anti-lock brake sensors are used by the computer to determine when a wheel loses pressure by how the revolution count changes relative to an 'initialized' full pressure reading recorded for that wheel/tire - so it doesn't use actual pressure readings (or in-wheel TPMS sensors) at all.

It hit 40f yesterday morning and my right side was parked in a puddle. Since I run my tires a bit low (first set developed terrible center wear at factory PSI), I started the car and the rear right tire was at 27 PSI. By the time I got to work, it had gone up to 33, but the light didn't go off.

The way it works is:
If you drop below 27 PSI, the warning comes on.
The warning light WILL NOT disappear until you hit 35+ PSI. (Not exactly 35 though, I had it reading 35psi for 5 minutes before it finally turned the light off)

Pain in the butt if you want to run below factory spec, you have to overfill, or fill and warm the tires. I ended up filling to 33psi cold, and just drove around. Gonna have to let some air out next week when we're back in the 90s and they're sitting at 40psi cold. Lol.

Note that these numbers are for the RWD GT, which recommends 36 all around, Likely the other versions will work similarly, though shifted to account for the wheel's recommended PSI.

 

[Metalmania82]

My tires are currently at 32 or 33, according to the display, no light. Usually the warning light won't go on until you're in the 20's. And it won't reset until you've driven a few miles, unless there's a reset feature in the car like the BMW's have, but we don't have those.
