obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
Use the ParkSense switch to turn the ParkSense system off
if objects such as bicycle carriers, trailer hitches, etc. are
placed within 12 inches (30 cm) from the rear fascia/
bumper. Failure to do so can result in the system misinter-

“PARKSENSE UNAVAILABLE SERVICE REQUIRED”

ParkSense should be disabled when the liftgate is in the
open position. An opened liftgate could provide a false
indication that an obstacle is behind the vehicle.
WARNING!

Parking curbs might be temporarily detected or not

proximity.
