CAUTION / NOTICE / HINT

NOTICE:: ·

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.

·

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

·

When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.

PROCEDURE

1.CHECK ILLUMINATION

Check if the illumination for the radio and display receiver assembly, steering pad switch assembly, heater control switch or others (hazard switch, transmission control switch, etc.) comes on when the light control switch is turned to the head or tail position.

Result:

Result	Proceed to
Illumination comes on for all components except steering pad switch assembly.	A
Illumination comes on for all components except radio and display receiver assembly.	B
No illumination comes on (radio and display receiver assembly, hazard switch, heater control switch, etc.).	C
