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:
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor
coming from the front of the engine compartment.
This is normally a result of moisture from
rain, snow, or high humidity accumulating on
the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze)
to enter the radiator...
