The optional Bridgestone Turanza EL 42 RFT "run-flat tires" on the 2002 Q45 are not repairable. If a run-flat tire has been punctured, it must be replaced.
If the low beam headlamp is inoperative, it may be repairable by replacing certain components rather than replacing the entire headlamp assembly. DO NOT REPLACE THE WHOLE HEADLAMP ASSEMBLY IF IT IS NOT NECESSARY.
2002 INFINITI Q45; IMPROPER GAP BETWEEN CASSETTE PLAYER FINISHER AND CENTER CONSOLE
If the gap between the cassette player finisher and center console is improper (i.e., too big) the cause may be an improperly adjusted cassette player. Use the Service Procedure on page 2 to adjust the cassette player to obtain the proper gap.
