OEM ADAS Radar Optimized Color Resources

Changes in advanced driver assistance systems (ADAS) radar technology are introducing new refinishing considerations. Paint film thickness not only may affect the performance of ADAS radars, color formula selection may also be a contributing factor. What resources do repairers have available?

How can color affect the performance of advanced driver assistance systems (ADAS)? Aluminum flake size, shape, and concentration may influence the signal of the radar that may negatively affect its performance. A weakened signal may prevent a radar from detecting an object accurately which could lead to a potential collision.

This series dives into some resources offered by vehicle makers relating to radar optimized colors precautions and considerations. The type of information can be vehicle-specific, color-specific or radar component-specific. These OEM-specific resources include:

  • Position statements
  • Service bulletins
  • Vehicle-specific service information

Improper color selection may cause ADAS to malfunction and potentially fail. Check OEM repair information to identify what restrictions may apply to the repairs you are considering. Always verify that the ADAS is functioning properly after completing repairs.
