Why doesn't APA position the vehicle where I want in the space?
• The driver allows the vehicle to roll in the opposite direction of the
transmission (such as rolling forward when R (Reverse) gear is
selected.
• You may be driving in R (Reverse). APA can only look for a parking
space while moving forward.
• There may be an irregular curb along the parking space. APA might
not be able to align the vehicle to curbs that are damaged, very
shallow or covered with material such as debris, leaves, snow, or tarps.
• The vehicles or objects bordering the space may not be positioned
appropriately.
• 'The vehicle was steered more than usual while driving by the space.
APA performs best when you drive the same distance past the entire
length of the parking space whenever parking your vehicle.
• The tires may not be installed and maintained correctly. For example,
one or more tires may not be inflated correctly, may not be of the
same size, or may not be authorized for use on this vehicle.
• The vehicle had a repair or alteration that is not authorized by the
manufacturer.
• One of the parked vehicles has a high altitude attachment (i.e. salt
sprayer, snow plow, moving truck high bed, etc.) High altitude
attachments may not be detected by the system.
• The parking space length or parked objects position have changed
after the vehicle has passed the parking space.
• The temperature around your vehicle changes quickly, such as driving
from a heated garage into the cold or after leaving a car wash. As a
result, the outside air temperature displayed in the vehicle may not be
close enough to the actual temperature. APA relies on correctly
sensing the temperature outside for precisely positioning the vehicle.
