Parking Brake Warning Chime

The parking brake warning chime sounds when the parking brake is applied and vehicle speed reaches approximately 2 km/h (1 MPH).

• The combination meter receives a parking brake applied signal from the parking brake switch.
• When the combination meter receives a vehicle speed signal from the ABS actuator and electric unit (control unit) (with ABS), vehicle speed sensor (without ABS or CVT) or the TCM (with CVT, without ABS), it sounds the buzzer.
