The system is designed to detect vehicles
that may have entered the blind spot zone

The system turns on when all of the
following occur:
You attach a trailer to your vehicle.
You have set up the trailer to work with
the system through the information
display.
You start your vehicle.
You shift into drive (D).
The vehicle speed is greater than
6 mph (10 km/h).
Note: If you switch the Blind Spot
Information System off, the Blind Spot
Information System with Trailer Tow
automatically turns off.
Note: If you connect a trailer to your vehicle
and do not set up the trailer through the
information display, the system turns off
and a warning message appears. See
Information Messages (page 125).
Note: When towing a trailer, the extended
blind spot zone range decreases to a short
fixed or non-variable distance behind the
trailer. The extended blind spot zone range
returns to 59 ft (18 m) when the trailer is
disconnected.
