CAUTION / NOTICE / HINT

Note


  • The vehicle is equipped with a Supplemental Restraint System (SRS) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the precaution for Supplemental Restraint System Click here.

  • Inspect the fuse for circuits related to this system before performing the following inspection procedure.

PROCEDURE


  1. CHECK ILLUMINATION


    1. Check if the illumination for the multi-media module receiver assembly, multi-display assembly, steering pad switch assembly or others (hazard switch etc.) comes on when the light control switch is turned to the head or tail position.
