Driving and Operating

Trailering App System will not display a
Trailer Detection Alert to the user when a
trailer is connected.

When a trailer is connected and the ignition
is off, the Trailering App System will
periodically pulse the lighting circuits of the
trailer to verify if it still connected. The
trailer lights may periodically flash as a
result of this trailer connection detection.
These flashes may be more visible in dark
ambient light environments. The flashing or
flickering lights are a normal condition and
the Trailering App System has built-in
protections to prevent the battery from
draining. When Theft Alert is also enabled
the frequency and pattern of this flashing
will change.

If a connected trailer becomes disconnected,
a message about the trailer disconnect will
appear on the DIC immediately (if vehicle is
on) or upon next ignition cycle (if trailer
was disconnected while vehicle is off). Check
your trailer connection if needed.

Connection Problem

If any of the trailer connections are lost, a
message about the connection issue will
appear on the Driver Information Center

(DIC). The infotainment display will also
show the connection issue in the Lights
Status view.

Connection Trailer Lighting Faults Detected

The Trailering App System monitors for
electrical faults on the trailer lights.
A message about the lighting issue will
appear on the DIC. The infotainment display
will also show the lighting issue in the
Lights Status view. Repair your trailer lights
if needed. A trailer lighting issue is not
covered by your GM warranty.

The Running Lights connection may not
detect partial outages. Activate the light test
to check all trailer lamps. See

Light Test

following.
