ISO 2575:2021/Amd 1:2024

Overview

ISO 2575:2021/Amd 1:2024 is the latest amendment to the international standard that defines symbols for controls, indicators, and tell-tales used in road vehicles. Published by the International Organization for Standardization (ISO), this update enhances the clarity and safety of automotive interface elements by introducing new standardized symbols. These icons communicate essential vehicle functions and warnings to drivers, promoting ergonomic consistency across different vehicle makes and models globally.

Key Topics

• Standard Symbols Update
  This amendment adds new symbols to the existing ISO 2575 standard, including those related to manual steering controls and child seat installation warnings. These new pictograms are designed to comply with recognized visual safety standards such as ISO 3864-1 for color coding and ISO 7010 for safety signage.

• Manual Steering Indicator
  A newly introduced symbol (ISO 7000-J.15, registration number 3893) indicates when a driver must keep their hands on the steering wheel or when manual steering is required. This helps improve driver awareness and control especially in vehicles with advanced driver assistance systems.

• Child Seat Installation Warning
  A critical symbol (ISO 7010-P074) alerts that a passenger seat is not suitable for installing a child seat if the front airbag is active, reducing injury risk in the event of deployment. This symbol uses a red circular ring and diagonal line with black icons on a white background for high visibility and quick recognition.

• Safety and Ergonomics Collaboration
  The standard is maintained by ISO Technical Committee ISO/TC 22 on Road Vehicles and Subcommittee SC 39 on Ergonomics to ensure symbols meet the latest ergonomic and safety principles.

Applications

• Vehicle Manufacturing and Design
  Automotive manufacturers integrate these standardized symbols in vehicle dashboards, control panels, and indicator lights. This harmonization aids global consistency, making vehicle operation intuitive for users worldwide.

• Automotive Safety Compliance
  The addition of child seat installation prohibitions in specific seating positions aligns with safety regulations aimed at protecting young passengers, helping manufacturers comply with evolving legal safety requirements.

• Driver Assistance Systems
  The manual steering symbol supports effective communication in vehicles equipped with driver assistance or semi-autonomous features, ensuring drivers know when manual control is necessary.

• Manual and Instruction Materials
  Automotive manuals, training materials, and service documents use these standardized symbols to convey technical information efficiently and universally.

Related Standards

• ISO 3864-1 – Specifies safety colors and design principles for safety signs utilized within the symbols for high visibility and international understanding.

• ISO 7010 – Provides standardized safety signs including those referred to in ISO 2575 for instructing safe behavior and hazard awareness.

• ISO 7000 – Contains a database of graphical symbols including those related to machinery controls, of which new icons are registered for road vehicle use.

• ISO/IEC Directives, Part 1 and Part 2 – Outline the procedures and editorial rules that guide the development and maintenance of all ISO standards, ensuring consistency and quality.

The 2024 amendment to ISO 2575 further advances the standardization of essential vehicle symbols, reinforcing road safety and user ergonomics. Adopting these clear, internationally recognized pictograms supports manufacturers, regulators, and drivers alike by fostering a safer, more comprehensible driving environment.
