- Summary
- Some customers may notice an unexpected collision warning or automatic braking while reversing. This concern may be due to the parking assist unit software. The Smart Brake Support (SBS-R) system may be detecting an unintended obstruction at the lower rear end of the vehicle. To eliminate this concern, the parking assist unit control software has been modified.
