- To Activate: Press the button marked 'AUTO H'. An indicator light will illuminate, signifying that the Automatic Hold function is active.
- Functionality: When active, the vehicle will automatically hold the brakes when stopped (e.g., at a traffic light or in traffic), preventing it from rolling. The driver can remove their foot from the brake pedal.
- To Deactivate: Press the 'AUTO H' button again. The indicator light will turn off.
6. Maintenance
To ensure the longevity and reliable operation of your parking brake control switch, consider the following maintenance tips:
- Regular Cleaning: Keep the switch surface clean from dust and debris using a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Avoid Liquid Exposure: Prevent liquids from spilling onto the switch, as this can cause internal damage or malfunction.
- Periodic Inspection: Periodically check the switch for any signs of physical damage, loose connections, or unusual operation.
7. Troubleshooting

Image: Visual examples of common issues that may necessitate replacing a power window switch, including a stuck button, a loose or broken switch, and overall switch panel failure.
- Button Stuck or Unresponsive:
Cause: Debris under the button, internal mechanical failure, or electrical contact issue.
Solution: Ensure the area around the button is clean. If the issue persists, the switch may need replacement. - Switch Loose or Broken:
Cause: Physical damage, improper installation, or wear over time.
Solution: Check if the switch is properly seated in its housing. If physically broken, replacement is necessary. - Switch Panel Failure (No Functionality):
Cause: Electrical connection issues, fuse blown, or complete switch unit failure.
Solution: Verify all electrical connections are secure. Check the vehicle's fuse box for any blown fuses related to the parking brake system. If fuses are intact and connections are good, the switch unit likely requires replacement.
For complex electrical issues or if troubleshooting steps do not resolve the problem, consult a professional automotive technician.
