DETECTION RANGE MEASUREMENT
NOTICE:
Perform the following measurement and inspection with the shift lever in a position other than P. Be sure to apply the parking brake and depress the brake pedal firmly to prevent the vehicle from moving.
(a) Turn the engine switch on (IG).
(b) Turn the intuitive parking assist system on.
(c) Detection range measurement:

| Measurement Area | Shift Lever Position |
| Front Corner | In any position other than P |
| Front Center | In any position other than P or R |
| Rear Corner | R |
| Rear Center |
(2) Move a 60 mm (2.4 in.) diameter pole near each sensor to measure its detection range. When measuring the longest-range detection of the front center sonar and the rear center sonar, use a wall or equivalent.
NOTICE:
These detection ranges are applicable when positioning the 60 mm (2.4 in.) diameter pole parallel or perpendicular to the ground. The detection range varies depending on the measuring method and type of obstacle (such as walls).
HINT:
Have an assistant move the pole.
