@ kedarbendre Its nothing but a smart marketing ploy. To make a mountain out of a molehill. The car , through its on board diagnostics will tell you whether the pollution from your car has increased beyond a certain limit set by Maruti. If it has , a light will come on the dashboard and you'll need to take it to the dealer. Simple isnt it? Look at the hue and cry created over it being the first car compatible with OBD-II. This is what differentiates Maruti from FIAT. The Linea has more features than Maruti can ever dream of putting in the SX4 , yet see the difference in approach to marketing. If only FIAT marketed its stuff as well....... Gurjinder.
