The Renault Laguna is a French-made mid-size family car that debuted in the European market in 1994. After the 2000 model year, the Renault Laguna received a major chassis redesign and an all-new line of engine configuration options. If you decide to perform certain maintenance tasks required for your 2003 Renault Laguna, you may wish to reset the service light indicator after completing them. Resetting the service light is an easy task that you can complete without the aid of a mechanic or an authorised service centre.
