Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Clean snow, ice, mud and heavy dirt from the rear-bumper sensor areas, then switch the ignition on.
- 02
Press the BSM switch and confirm the BSM warning light in the instrument cluster is off, indicating the system is enabled.
- 03
Above approximately 19 mph (30 km/h), watch for a steady warning light in the applicable outside mirror when another vehicle is detected.
- 04
If you activate the turn signal toward that vehicle, treat the flashing mirror light and audible alert as a warning not to change lanes.
- 05
Check the mirrors, look over your shoulder and change lanes only after confirming the path is clear.
Important limits
- The system normally does not operate below about 15 mph (25 km/h) or while Reverse is selected.
- BSM is an aid and never replaces mirrors, shoulder checks or driver judgment.
- Snow, ice, mud or damage around the rear-bumper sensors can reduce or prevent detection.
Quick checks.
- ✓Press the BSM switch again if the cluster's BSM warning light shows the system is off.
- ✓Clean both rear-bumper sensor areas and retry above the operating-speed threshold.
- ✓Have the system inspected if its warning light or fault indication persists with clean sensors.
