No. xxxxxxxxx Page 9 of 16 INTEGRATION AND MOUNTING GUIDELINES This chapter describes the characteristics relevant to the installation of NB-SRR sensors in the bumper. In addition general specifications are mentioned, which have to be followed for each position to enable sufficient sensor performance. Therefore the following guidelines are to be observed carefully. 6.1.

No. xxxxxxxxx Page 12 of 16 Effect Of Type- And Thickness Of Fascia Material Autoliv has examined various fascia material samples with a thickness of 2.5 – 4 mm. For those samples, the radar signal is attenuated by 0.5 – 2 dB (corresponds to reduction of the range of coverage of 2 – 11%). Impact reducing material (foam) causes additional attenuation, especially when water is absorbed.
Product Description, User Manual, Installation Guideline SENSOR MODULE, RADAR, SRR, NB 6.5. Doc. No. xxxxxxxxx Page 13 of 16 Feature installation guidelines The sensors should be located in the optimal location for best overall coverage and range performance. The optimal locations will be dependent upon the specific application and the bumper characteristics. 6.5.1 Sensor Connector Orientation The Sensor connector orientation must be oriented rearward. 6.5.
