The system does not offer a particular space
The sensors may be covered (for example, snow, ice or dirt buildup). Covered sensors can affect the system's functionality.
There is not enough room in the parking space for your vehicle to safely park.
There is not enough space for the parking maneuver on the opposite side of the parking space.
The parking space is farther than 5 ft (1.5 m) or closer than 16 in (0.4 m) away.
Your vehicle is going faster than 22 mph (35 km/h) for parallel and 19 mph (30 km/h) for perpendicular parking.
You recently disconnected or replaced the battery. After a battery disconnect, the vehicle must be driven on a straight road for a short
period of time.
The system does not position the vehicle where I want in the space
Your vehicle is rolling in the opposite direction of the transmission (rolling forward with reverse [R] selected).
An irregular curb along the parking space prevents the system from aligning your vehicle properly.
Vehicles or objects bordering the space may not be positioned correctly.
Your vehicle was pulled too far past the parking space.
The tires may not be installed or maintained correctly (not inflated correctly, improper size, or of different sizes).
A repair or alteration has changed detection capabilities.
