And about the MPG for the current tank..is there any way to reset that thing prior to a trip? Because on Benz's and BMW's that number can be reset or automatically resets for every drive cycle. Let's say I start my car in the morning and avg 25mpg to get to work. When I turn the car on it'll show w/ the same mpg but is there a way I can reset it without having to fill the tank? The only time I can get the MPG on the TANK display to reset is when I fill up. Is there a way to reset this display for every single trip?
You hold the DISP button and the tank avg clears

the tank avg should reset everytime after your fill-up.......

if you want it to reset it manually, you hold the button and it will reset.

I never trust the display....


I've gotten 30mpg driving 80% hwy and 20% city using curise control most of the time.

with a 60/40 mixture I usually get about 26MPG

I've been driving conservative and using cruise control more often now... and I do see the MPG slowly creep up. I'm basing all my #'s from my a log I have that keeps track of my MPG and not from my display.

right now I have about 27k on the 250 and it's 100% stock

I pumped in fremont for 49.09 for around 10 gallons. On the drive home the display read 32 mpg i was going roughly 65-75. Im sure when i go to LA i will get around the same MPG.
