This SAE Recommended Practice establishes guidelines for the operation of automotive keyless ignition systems with the goal of helping to minimize user instigated errors. For the purpose of this Recommended Practice, user instigated errors may include: the inability to start and stop the vehicle propulsion system, exiting the vehicle with the automatic transmission in a non-parking gear, exiting the vehicle while the vehicle propulsion system is enabled, exiting the vehicle while the vehicle propulsion system is disabled, but the accessory or electrical systems are active. To help minimize these errors, this Recommended Practice contains design recommendations pertaining to uniform labeling, operating logic, indication of vehicle ignition/control status, and physical control characteristics of keyless ignition systems. This Recommended Practice applies to keyless ignition controls permanently mounted in passenger cars, MPVs, and trucks 10 000 GVWR and under.

The purpose of this SAE Recommended Practice is to describe design criteria pertaining to the location and labeling of hand controls necessary to or frequently used during the operation of passenger cars, MPV, and trucks 10 000 GVW and under. The results of SAE human factors research have strongly influenced these recommendations, specifically in the areas of driver reach, control-locating performance, and control location expectancies. Deviations from this recommended practice should be made only after careful study of the various SAE publications on these subjects, as referenced here and in SAE J1139 (September, 1977), Supplemental Information—Driver Hand Controls Location for Passenger Cars, MPV’s and Trucks (10 000 GVW and Under).

This SAE Standard specifies symbols (i.e. conventional signs) for use on controls, indicators, and tell-tales applying to passenger cars, light and heavy commercial vehicles, and buses, to ensure identification and facilitate use. It also indicates the colors of possible optical tell-tales, which inform the driver of either correct operation or malfunctioning of the related devices.
