3. APPLICATION FOR APPROVAL
3.1. The application for approval of a vehicle type with regard to the specification for controls,
tell-tales and indicators shall be submitted by the manufacturer or his duly accredited
representative.
3.2. It shall be accompanied by the following documents and particulars in triplicate:
3.2.1. A description of the vehicle type;
3.2.2. A list of items specified by this Regulation in Table 1 and prescribed by the manufacturer for
the vehicle as controls, tell-tales or indicators;
3.2.3. Graphical design of symbols identifying controls, tell-tales and indicators; and
3.2.4. Drawings and/or photographs showing the layout of controls and location of tell-tales and
indicators in the vehicle;
3.3. A vehicle or representative part thereof fitted with a complete set of controls, tell-tales and
indicators, as prescribed in Paragraph 3.2.2. above, representing the vehicle type to be
approved shall be submitted to the technical service responsible for conducting approval
evaluation.
4. APPROVAL
4.1. If the vehicle type submitted for approval pursuant to this Regulation meets the
requirements of the Regulation, approval of that vehicle type shall be granted.
4.2. An approval number shall be assigned to each type approved. Its first two digits (at
present 01 corresponding to the 01 series of amendments to the Regulation) shall indicate
the series of amendments incorporating the most recent major technical amendments made
to the Regulation at the time of issue of the approval. The same Contracting Party shall not
assign this number to another vehicle type or to the same vehicle type submitted with
equipment not specified in the list referred to in Paragraph 3.2.2 above, subject to the
provisions of Paragraph 6 of this Regulation.
4.3. Notice of approval or of extension or refusal of approval or production definitively
discontinued of a vehicle type/part pursuant to this Regulation shall be communicated to the
Parties to the 1958 Agreement applying this Regulation, by means of a form conforming to
the model in Annex 1 to this Regulation.

5.1.3. The identifications of tell-tales, indicators and controls shall be placed on or adjacent to the
tell-tales, indicators and controls that they identify. In the case of multifunction control, the
identifications need not be immediately adjacent. Nonetheless, they shall be as close as
practicable to such multifunction control.
5.1.4. Notwithstanding Paragraphs 5.1.1, 5.1.2 and 5.1.3 the tell-tale for "passenger air bag off", if
fitted, shall be located within the interior of the vehicle and forward of and above the design
H-point of both the driver's and the front passenger(s)' seat in their forward most seating
positions. The tell-tale which alerts front seat occupants that the passenger air bag is
switched off shall be visible to the driver and front passenger(s) under all driving conditions.
5.2. Identification
5.2.1. Where fitted, the controls, tell-tales and indicators, listed under the heading Column 3 of
Table 1, shall be identified by symbols designated for them in Column 2 of Table 1. This
requirement does not apply to the horn (an audible warning signal) control, when it is
activated by a narrow ring-type control or by a lanyard. If a symbol is used for identifying a
control, tell-tale or indicator not listed in Table 1, it is recommended to use a symbol
designated for the purpose in Standard ISO 2575:2004 where one exists and where that
symbol is suitable for the application concerned.
5.2.2. To identify a control, a tell-tale or an indicator not included in Table 1 or ISO 2575:2004, the
manufacturer may use a symbol of its own conception. Such symbol may include
internationally recognized alphabetic or numeric indications. All symbols used shall follow
the design principles laid down in Paragraph 4 of ISO 2575:2004.
5.2.3. If necessary for clarity, supplementary symbols may be used in conjunction with any symbol
specified in Table 1 or ISO 2575:2004.
5.2.4. Each additional or supplementary symbol used by the manufacturer shall not cause
confusion with any symbol specified in this Regulation.
5.2.5. Where a control, an indicator or a tell-tale for the same function are combined, one symbol
may be used to identify such combination.
5.2.6. Except as provided in Paragraph 5.2.7., all identifications of tell-tales, indicators and
controls listed in Table 1 or ISO 2575:2004 shall appear to the driver perceptually upright. In
case of rotating control, this paragraph applies to it when such control is in its "off" position.
5.2.7. The identification of the following need not appear to the driver perceptually upright:
5.2.7.1. A horn control,
5.2.7.2. Any control, tell-tale or indicator located on the steering wheel, when the steering wheel is
positioned for the motor vehicle to travel in other than a straight forward direction, and
5.2.7.3. Any rotating control that does not have an off position.
5.2.8. Each control for the automatic vehicle speed system (cruise control) and each control for
heating and air conditioning system(s) shall have identification provided for each function of
each such system.

5.4.3. Each symbol used for identification of tell-tale, control or indicator shall stand out clearly
against the background.
5.4.4. The dark part of any symbol may be replaced by its outline.
5.5. Common Space for Displaying Multiple Information
5.5.1. A common space may be used to show information from any source, subject to the following
requirements:
5.5.1.1. The tell-tales and indicators in the common space shall provide relevant information at the
initiation of any underlying condition.
5.5.1.2. When the underlying condition exists for actuation of two or more tell-tales, the information
shall be either
5.5.1.2.1. Repeated automatically in sequence, or
5.5.1.2.2. Indicated by visible means and capable of being selected for viewing by the driver under the
conditions of Paragraph 5.6.2.
5.5.1.3. The tell-tales for the brake system malfunction, headlamp driving beam, direction indicator
and seat belt shall not be shown in the same common space.
5.5.1.4. If tell-tale for the brake system malfunction, headlamp driving beam, direction indicator or
seat belt is displayed in a common space it shall displace any other symbol in such common
space if the underlying condition exists for its activation.
5.5.1.5. With the exception of tell-tales for the brake system malfunction, headlamp driving beam,
direction indicator or seat belt, the information may be cancellable automatically or by the
driver.
5.5.1.6. Unless prescribed in a specific Regulation, the colour requirements regarding tell-tales do
not apply when tell-tales appear in a common space.
5.6. Conditions
5.6.1. The driver has adapted to the ambient light conditions.
5.6.2. The driver is restrained by the installed crash protection system, adjusted in accordance
with the manufacturer's instructions, and is free to move within constraints of that system.

10. NAMES AND ADDRESSES OF TECHNICAL SERVICES RESPONSIBLE FOR
CONDUCTING APPROVAL TESTS AND OF TYPE APPROVAL AUTHORITIES
The Parties to the 1958 Agreement applying this Regulation shall communicate to the
United Nations Secretariat the names and addresses of the technical services responsible
for conducting approval tests and of the Type Approval Authorities which grant approval and
to which forms certifying approval or extension or refusal or withdrawal of approval, issued
in other countries, are to be sent.
