ISO (the International Organization for Standardization) is a worldwide federation of national

standards bodies (ISO member bodies). The work of preparing International Standards is normally

carried out through ISO technical committees. Each member body interested in a subject for which a

technical committee has been established has the right to be represented on that committee.

International organizations, governmental and non-governmental, in liaison with ISO, also take part in

the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

ISO 3864-1, Graphical symbols — Safety colours and safety signs — Part 1: Design principles for safety

ISO 15008, Road vehicles — Ergonomic aspects of transport information and control systems —

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

visually perceptible figure used to transmit information independently of language, produced by

display that indicates, by means of a light-emitting device, the actuation of a device, a correct or

visually perceptible graphic, generally larger in size than a symbol, designed for a label, tag or sticker

modification of symbol originals in order to maintain visual clarity and overall consistency

4.1 The symbols and signs shall be as given in Annexes A to N and Annex X. Additional symbols are

given in Annexes W, Y and Z. Minor deviations to the symbols and signs are permitted, provided they

are necessary to reproduce an accurate representation to the driver's line of sight.

NOTE Additional annexes can be included in future editions of this document if necessary.

4.2 In developing the symbols and signs shown in Annexes A to Z, legibility factors such as line

thickness, gaps between lines, symbol and arrow shapes, etc. were carefully considered. Modifications

that improve legibility are permitted in the circumstances specified in 4.2.1, 4.2.2 and 4.2.3. When

modifying symbol elements, the graphic designer should consult IEC 80416-1, ISO 80416-2, IEC 80416-

4.2.1 Limitations inherent in some reproduction and display technologies can require increased line

thickness or other minor modifications of symbols. Such modifications are acceptable provided the

symbol remains unchanged in its basic graphical elements and is easily discernible by the operator.

4.2.2 Additionally, to improve the appearance and perceptibility of a graphical symbol or to

coordinate with the design of the equipment to which it is applied, it can be necessary to change the line

thickness or to round off the corners of the symbol. The graphic designer is normally free to make such

changes provided that the essential perceptible characteristics of the symbol are maintained.

4.2.3 The graphic designer may render a symbol in either outline or solid form unless this is otherwise

4.3 The shapes of the vehicle, seat and steering wheel shown in this International Standard are not

intended to be restrictive but are the recommended shapes. Modifications to these shapes may be

introduced by designers in order to better represent the true shape of a given element. Except for the

aforementioned shapes, no other symbol elements shall be changed, except as provided in 4.2 or in the

4.4 If a symbol shows a vehicle or parts of a vehicle in a side view, a vehicle moving from right to left

in the symbol area shall be assumed. If a symbol shows a vehicle or parts of a vehicle in a top, plan view,

4.5 For actual use, all symbols shall be reproduced large enough to be easily discernible by the

operator. See IEC 80416-3 for guidelines on the proper sizing of symbols. Symbols shall be used in the

orientations shown in this document unless otherwise noted for individual symbols.

4.6 Symbols on controls and displays shall contrast well with their background. For most controls, a

light symbol on a dark background is preferred. Displays may use either a light symbol on a dark

background or a dark symbol on a light background, depending on which alternative provides the best

visual perception. When a symbol image is reversed (for example black to white and vice versa), it shall

4.7 For symbols that are displayed using pixel matrices, the character matrix shall be as stipulated in

4.8 Letters and numerals may be used as symbols. For example, the letters P, R, N, D, have the

meaning indicated when used in association with transmission gear controls and displays on road

vehicles. The fonts shown in this document are not intended to be restrictive; other fonts may be

The grid marks “∟” denote the corners of the original 75 mm square. The grid marks are not part of the

symbol but are provided to ensure consistent presentation of all symbol graphics.

or elements of symbols from this document in a logical manner, keeping the coherence with other

5.1 When used on optical indicators or tell-tales, the following colours have the meanings indicated:

— red: danger to persons or very serious damage to equipment, immediate or imminent;

— yellow or amber: caution, outside normal operating limits, vehicle system malfunction, damage to
