When to Reset Hill Start Assist

You may need to reset your Hill Start Assist if:

  • You see a "Hill Start Assist Not Available" warning
  • The system isn't engaging on inclines
  • You've recently had brake work done
  • The battery has been disconnected

Troubleshooting

If the reset doesn't work, consider these steps:

  • Check your vehicle's manual for model-specific instructions

  • Inspect brake fluid levels and brake system components
  • Consider having a professional diagnose the issue if problems persist

Remember, a properly functioning Hill Start Assist system is crucial for safety when driving on inclines. If you're unsure about the reset process or continue to experience issues, it's best to consult with a certified mechanic.
