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”
message to be displayed in the instrument cluster.

ParkSense should be disabled when the liftgate is in the

indication that an obstacle is behind the vehicle.
WARNING!
• Drivers must be careful when backing up even when

is behind the vehicle.
CAUTION!
• ParkSense is only a parking aid and it is unable to

Parking curbs might be temporarily detected or not
