INSTRUMENT PANEL
Tell-Tales
A tell-tale is a display that indicates the actuation of a device, a correct or defective
condition, or a failure to function.
The operator should become familiar with these symbols in order to recognize and
react (if necessary) to the indicated condition. Tell-tale symbols are shown in the
instrument panel illustrations on the following pages.
Colors
To promote visual recognition internationally, specific colors for tell-tales have been
established. Unless governmental regulations (in the area where the vehicle is to be
used) or engineering directives specify otherwise, the standard colors are:
•
Blue
— high-beam headlights/engine maintenance
•
Flashing Green
— turn signals
•
Flashing Red — hazard condition involving the safety of personnel
•
Steady Green — system in operation
•
Steady Red — warning, immediate action required
•
Amber — early warning, such as low fuel or Anti-Lock Brake System (ABS)
