Jeep Wrangler: Blind Spot Monitoring (BSM) — If Equipped / Entering From The Side
Vehicles that move into your adjacent lanes
from either side of the vehicle.

Side Monitoring
The BSM system uses two radar sensors,
located inside the taillights, to detect highway
licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot
zones from the rear/front/side of the vehicle...
Vehicles that come up from behind your vehicle
on either side and enter the rear detection zone
with a relative speed of less than 30 mph
(48 km/h)...
Other information:
During vehicle start up, when the ParkSense
Rear Park Assist System has detected a faulted
condition, the instrument cluster display will
actuate a single chime, once per ignition cycle,
and it will display the “PARKSENSE
UNAVAILABLE WIPE REAR SENSORS” or the
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message...
Turn Signals
Move the multifunction lever up or down to
activate the turn signals. The arrows on each
side of the instrument cluster flash to show
proper operation.
NOTE:
If either light remains on and does not flash, or
there is a very fast flash rate, check for a defective
outside light bulb...
