The driver warning chime provides the driver with an audible warning for ignition on, key in ignition, driver door open and lamps on.

The system uses a number of inputs to provide the driver with audible warnings

Central Timer Module (CTM)

The central timer module (CTM) acts as the system monitor for the driver audible warnings. It receives inputs from the switches and triggers the warning chime.

Ignition Switch Lock Cylinder

A warning chime will sound continuously when the driver door is opened and the key is in the ignition, on removal of the key the warning chime will cease. The switch is an integral part of the ignition switch cylinder.

Headlamp Switch

A warning chime will sound continuously when the driver door is open and the vehicle lamps are on. This warning is provided whether the key is in or out of the ignition and will cease when the lamps are switched off.

Courtesy Lamp Switch

The driver door courtesy lamp switch activates the system to give a warning for key in ignition and lamps on, door open/ajar. Neither of the warnings will occur until the driver door is open.
