FREQUENTLY ASKED QUESTIONS
Why is reverse braking assist unavailable?
• Make sure the reverse braking assist is
on. See Switching Reverse Braking
Assist On and Off (page 239).
• Make sure that all doors, liftgate or
tailgate and hood are closed. Drive the
vehicle on a straight road for a short
period. If the message remains, have the
system checked.
• If your vehicle has the cross traffic alert
system, make sure it is on. See Switching
Cross Traffic Alert On and Off (page 318).
• Make sure the rear parking aid system is
on. See Parking Aids (page 255).

activated.
• Your vehicle may have sustained a rear
end impact. Have the sensors checked
for proper coverage and operation.

stability control event may have occurred.
Reverse braking assist resumes
operation when the event is complete.
• Make sure the rear view camera and 360

the message still appears after cleaning
the camera, wait a short time for the
message to clear. If the message does
not clear, have the system checked.

parking aid and side parking aid sensors
are not blocked or faulty. See Locating
the Cross Traffic Alert Sensors (page
