i have recently bought a second hand renault scenic, 1.6, y plate automatic. it did not come with any handbooks, i have purchased some by ebay which will duly arrive in a couple of days, however twice now when i have driven her when getting up to about 50mph she seems to rev up and the a yellow auto light comes on? i just wanted to know what it means?? nothing bad i hope! it goes off after i start her up again, please help!
