When I reset Trip B it resets Trip A also; not the behavior I was expecting nor did I want. I thought each Trip reset indepenently?

I don't know, but I discovered recently that apparently each trip odometer tracks average fuel economy separately.

 

I have an 11 and mine does not do that. I would call the dealer. Does it do it consistantly?

 

yup, a and b.

everytime you refil gas, it resets if you are on a or on b.

make sure when you fill gas, you are on a side of you want to reset a or vise verse..

 

Yes, it's a nice feature. I leave it on trip A when I refuel and that gives me MPG for that tank; I leave trip alone and that gives me my running average.

(I hope I'm not turning into a hyper-miler, but I find myself getting frustrated when in a lot of stop and go or highway congestion because I just know it's killing my MPG!)

 

I stand corrected. You are right! I did not know that it automatically does that. I always reset it manually before starting to move from the gas pump. Learned something. Thanks!

 

I believe they are programmable through MID. I did make trip A to reset everytime when I refill the gas, so I know what I got out of this tank. My trip B never got reset from day 1, so it is actually showing the mpg for the life of the car.

 

How does it know that your refilling the tank? That's genuis!!!!

 

its a TL, it knows everything....

but yea, my B side gets reset everytime i go in for an oil change.. so it tells me whats my overall mileage after every change.. and plus it tells me how much miles i have ran under B side so i can accurately calculate my oil changes.

 

LOL the TL does know everything!!!

How often do you recommend I get an oil change? every 5K?

 

That's a controversial topic... The car will tell when it thinks the oil needs changing but, you can change it every 3k miles, if you want. I just did my A1 (first oil change) and the it got to 15% @ roughly 7K miles.

 

Thanks for all the replies; but with all due respect, you have hijacked my question. I'm not asking anything about the MPG reset or oil changes.

1. I have the auto reset on refuel OFF.

2. I manually reset A; B does not reset.

3. I manually reset B; BOTH A and B reset.

Why does reseting B clear both A and B is my question.

No offense intended to contributors.

 

You're absolutely right -- we did hijack your thread. Very sorry.

As to your question, that's a stumper. I've always had my auto reset "on" for refuel, so I've not used your particular setting, but it does not seem logical that resetting trip B would also reset trip A.

 

Sorry man, didn't mean to do that.. I'd recommend taking it in to a dealer.

 

Mooring, that just doesn't sound right. I would definitely ask the dealership about it.

 

I have a 2011 and mine does not do that. Trip A is for tank average and trip B is for vehicle average.

 

Good question, though I can't (or won't) confirm, as I've never reset my trip B - it has about 3,200 miles (since I bought the car last October).
