adjacent vehicle, or a person or object
entering the parking space. APA does not
detect or avoid traffic that is behind or

prepared to stop the vehicle during the
parking maneuver.
How to Activate Automatic Parking
To activate APA, press on the center
stack for the system to begin searching for
a parking space while driving forward at no
greater than 30 km/h (18 mph). By default,
APA searches for parallel parking spaces to
the right of the vehicle up to 1.5 m (5 ft). To
search for a parking space to the left, turn
on the left turn signal or, if available,
change the side selection in the
infotainment display. To switch the parking
mode between parallel and perpendicular,
press and hold while searching for a
valid parking spot or, if available, change the
parking mode in the infotainment display.

comfortably.
Have an adjacent vehicle, wall, or pillar
for the system to align to.
After completely passing an eligible parking
spot, a beep sounds and a red stop symbol
is displayed in the Driver Information Center
(DIC). Generally, APA selects the nearest
empty parking spot behind the vehicle, but
under some conditions may select a space
that is further back. Slow down and bring
the vehicle to a complete stop to begin.
Follow the displayed instructions. When
prompted, shift to R (Reverse) while holding
the brake. The steering wheel will vibrate
briefly as a reminder to remove hands from
the steering wheel. Release the brake slowly
when the vibration stops to begin automatic
parking. As the vehicle automatically steers,
brakes, accelerates, and shifts gears into the

parking spot, check surroundings. Be
prepared to stop to avoid vehicles,
pedestrians, or objects.

parking maneuver. Once automatic parking
