CHIME DOES NOT SOUND
Description
INFOID:0000000003130130
The chime may not sound occasionally in the following cases even if the distance from the vehicle ahead is
short:
• When the speed difference from that of the vehicle ahead is small (both vehicles driving at similar speed).
• When the vehicle ahead drives at faster speed (the actual distance is increasing).
• When depressing the accelerator pedal.
• Chime does not sound when the vehicle ahead is not driving.
• Chime does not sound when the system does not detect any vehicle ahead. (Diagnose the conditions under
which the system is detecting the vehicle ahead and when the system is malfunctioning. If there is any mal-
function in detecting the vehicle ahead, check the system following the
