TEXT:

I have two automotive instrument panel telltale warnings I wish to confirm are legal in the views of the NHTSA Legal Council and FMVSS. The attached sheet shows my two proposals.

The first is a 4 wheel antilock brake application. Techically, I believe this telltale is legal due to the approved abbreviation "ABS" being present. I have seen the antilock brake ISO symbol which is similar to the one I have shown except the car and "skid marks" are replaced with the "ABS" abbreviation. My question here is, Will this telltale fullfil the requirements or do I need to replace the car and "skid marks" ISO symbol with the "ABS" ISO symbol?

The second telltale is used for warning against hazardous emissions from the vehicle. I have seen numerous telltales relating to this application. A few you may be familar with "SERVICE ENGINE SOON", "SERV ENG SOON", "CHECK ENGINE" or simply "CHECK". I would like to know two things concerning this application. One, is the word "CHECK" necessary with the engine outline? Two, is the engine outline an approved ISO symbol and if not yet will it be concidered at a later date?

Please respond on or before August 27 1990 as I must begin a production run with these telltales. Thank you for your assistance and if you need to contact us please call Mike Benoit at (313) 853-2266.
