During lane changes, the design of the
blind spot assist feature detects vehicles
in, or approaching, your blind spot and
provides a warning, plus steering
assistance to direct your vehicle back into
your lane.
If a supported trailer is connected, the
function is reduced to only detecting
vehicles on both sides of your vehicle and
trailer, extending rearward from the
exterior mirrors to the end of your trailer.
See Blind Spot Information System
With Trailer Coverage (page 307).
When active, this system functions with or
without the use of direction indicators and
hazard flashers.
You must keep your hands on the steering
wheel at all times.
