Dear all,
I have purchased 97 S500 and out about 1000 miles into the car. Now the radiator light on and off when driving on the flyover, the light will off when cruising on the freeway,
I wuold like to know
1) How can i check if the coolant level is low?
2) Is it normal that these car drink coolant? I cannot find any leak
3) What is the normal temp for city driving? mine is a little bit lower then 100degree mark, when on freeway, slightly over 80

Thanks!
