Blind Spot Monitor / Rear Cross Traffic Alert
Informational — For your awareness
What It Means
The blind spot monitoring or rear cross traffic alert system is temporarily unavailable or has a fault. These systems use radar sensors (usually behind the rear bumper) to detect vehicles in adjacent lanes.
Common Causes
- Radar sensors blocked by mud, snow, or ice (clean bumper corners)
- Heavy rain or snow interfering with radar signal
- Trailer attached (many vehicles disable BSM when towing)
- Radar sensor misaligned or faulty
- System turned off (check vehicle settings)
Can I Still Drive?
Yes — use mirrors and shoulder checks for lane changes. This is a driver assistance feature only.
