Depends if you have DIS (driver information system) or not.
If you do, the display (in between the dials) will have 3 seperate bits, the top shows radio station/Cd track number (and any warnings: oil level, washer level, fuel low etc) the middle is outside temp (i think!!), and the bottom bit shows: average mpg, Current mpg, average speed, amount of time you've been driving, & number of miles left in the tank.
If you don't have DIS, then you won't have the bottom bit, and maybe not the middle (showing outside temp), and afaik there will be just 2 sections instead of 3 on the display.
Ff you have DIS, on the right column stalk there is a rocker switch on the end, you cycle through the bottom section with this.
hope this helps
