I have always seen this reading on my dashboard right below my odometer but don't know what it stands for.

GAZZUZZ:
e mean say your nissan don really waka

One is the overall mileage of the car, 200k while is the other is set to read short distances, in most cars it will not read more that 999km or miles once reset.

But wait o, who taught you to drive?

thank u boss. Although I no understand finish.
does it mean it won't read long distances? cos i have never really travelled with it in my 14months driving experience.....can it be reset without resetting the overall mileage??

Yes it can be reset without reseting your odometer. It is a trip counter and you can use it for whatever purpose you wish...say you want to measure the distance you travel between refills or the distance you travel in a day or week or month..then you use the trip counter...or that's what I use mine for.
