HINT: This setting is only valid for the buzzer which sounds at the 5 km/h (3 mph) or more.

2. SEAT BELT BUZZER ON/OFF SETTING (Procedure "A")

The seat belt buzzer ON/OFF setting, which is a setting of the buzzer function of the combination meter, can disable the driver and front passenger side seat belt buzzers.

NOTICE:

• These buzzers should be on for safe driving.

Perform these procedures only if it is necessary to set the buzzer off (disabled).

• When either the battery cable or the combination

meter connector is disconnected, these buzzers are set on (enabled).

• Odometer returns to 0 after starting this

procedure, although it is not displayed.

HINT: "b-oFF" indicates that the buzzer is OFF. "b-on" indicates that the buzzer is ON. The seat belt buzzer ON/OFF setting will be finished (the odometer will display "ODO") if the ODO/TRIP switch is not operated for 10 seconds or more. In this case, perform step 11 to check that the buzzer ON/OFF setting is complete. If it is not complete, start from step 1 again. (a) Driver and front passenger side seat belt buzzers

(1) Turn the ignition switch on (IG). (2) Press the ODO/TRIP switch until the odometer

displays "ODO". (3) Ignition switch off. (4) Turn the ignition switch on (IG). (5) Press the ODO/TRIP switch immediately (within

6 seconds) and hold it down for 10 seconds or

more. (6) Continue holding down the ODO/TRIP switch

and fasten the driver side seat belt.

(b) Front passenger side seat belt buzzer

(1) Turn the ignition switch on (IG). (2) Press the ODO/TRIP switch until the odometer

displays "ODO". (3) Ignition switch off. (4) Turn the ignition switch on (IG). (5) Sit in the front passenger seat. Press the ODO/

TRIP switch immediately (within 6 seconds) and

hold it down for 10 seconds or more. (6) Sit in the front passenger seat. Continue holding

down the ODO/TRIP switch and fasten the front

passenger side seat belt. (7) Check that the odometer displays either "b-on"

or "b-oFF". (8) Press the ODO/TRIP switch to change the

display to "b-oFF". (9) Ignition switch off. (10)Turn the ignition switch on (IG). (11)Check that no buzzer sounds.
