It is a total average, until you reset it. Try reseting it while you're on the highway going downhill. I had 110mpg for a little while.

 

It's a rubbish system, not displaying current usage is just as mind boggling as the absurd HVAC.

 

It's a little bit inaccurate but if you can get used to it, it gives a decent recording. The total that reads after a few days shows the average L/100KM. If you had previously been doing highway driving, it should give you a pretty low reading of around 7-.7.8 L/100KM. A mix of highway driving and city driving will give you that large number. Go to the setting and hold the clear button for a few seconds and it'll start recording your average mileage again, do it when you first begin driving in the city and by the time you've been going for a little while, you'll have a recording. You just have to clear it each time to get a display of actual present mileage.

 

ps. What kind of fuel consumption you guys get? What is a good number?

Is your car an auto or manual?
Mine is manual and in city traffic I get around 12.5lt/100Km by driving decently and normally. On the highway with cruise control and 100Km/h I get around 7.1Km/100Km.

When I reset the display, it takes around 8-10Km before I get a more accurate reading.
Immediately after the reset it always shows peculiar readings, e.g. when I drive out of my underground parking lot it shows 99lt/100Km !!!
Quirky Saab!

 

Just a mention..... don't rely on the DTE reading to get fill ups, more than one person has burned out a fuel pump going dry when the DTE said they had way more than several miles to go.

 

My DTE has been reliable. I think its foolish to drive so long on an obviously running on fumes quantity of fuel anyways. I never go longer than 30 km DTE.

 

Mine is automatic, 4 cylinders, turbo...

Thanx for the responses. After resetting it about 4 days ago finally it sort of stabilized yesterday at 16l/100kms, which is quite a lot (only city driving). Will try it manually next time. Fill it all the way up, drive for a 100kms then refill it again. Will compare it to the computer.

 

16 is bloody high, i get about 14 if really cold and i find that terrible given the advertised 10.7.

 

When you took off from gas station, after you press the CLR buttom. You were driving the first and second gear, that will use alot of gas. That is why the number so high.

BTW, the window sticker say highway 29MPG. I never able to do it on highway. Does it need to drive 55mph to get that number?

 

I can get up to 34 on long trips. City driving I get 24-26.

In my opinion, an instantaneous reading isn't all that useful. You can use the turbo gauge for that!

 

one more question. While at the subjects or resetting things...

How do I reset that distance driven on the main screen at the buttom on the right hand, next to the milage driven in total?

 

The Saab systems are "quirky", that is they f'ing suck.

My old 1998 Volvo has better, easy to read, real time and average numbers.

Saab? Yeah and for the small tank and poor mileage the yellow does not come on until the DTE is last moment. I suspect the gauge is a bit late in reading too because I often, often, often check on the ride home to see if I need gas. Next time I start the car it is low down and the light comes on.

The old Volvo is AWD and heavy but got 23, this thing is "more nimble" but can only do 19 with less weight, at least the Volvo has a large tank and gets about 400 miles. This Saab probably strains at the SAE mandated figure of 300.

 

I average around 30mpg combined (highway/city) over full tank of gas, I dont drive 55mph either
