What does the CH indicator in a car mean?
2 Answers
CH in a car refers to the coolant temperature indicator. CH is used to alert the temperature of the coolant inside the engine, with blue indicating the coolant is too cold and red indicating it is too hot. The car dashboard is a rigid panel or structural component used to install instruments and related devices. It can be categorized by form into: 1. Screen-type dashboard; 2. Frame-type dashboard; 3. Channel-type dashboard; 4. Cabinet-type dashboard. Other indicators on the car dashboard include: 1. Engine malfunction light; 2. Airbag indicator; 3. Coolant temperature indicator; 4. ABS warning light; 5. Seatbelt reminder light; 6. Car battery indicator; 7. Door ajar indicator; 8. Handbrake light; 9. Turn signal light.
When I first bought my car, I was also puzzled about what the CH button meant. Later, I learned that it's actually the channel button on the radio. There are CH-labeled buttons on the steering wheel or center console, and pressing them switches to the next station. For example, if you're listening to traffic radio and find it boring, a quick press on CH jumps to a music station. Some cars even have memory functions—holding down a number key can save your favorite station. If the CH button stops working, it's likely due to poor contact or a blown fuse; often, prying it open and cleaning the contacts will fix the issue. Nowadays, new cars use voice control, making it easier to just say "change station," but seasoned drivers know mechanical buttons are the most reliable.
