(3) Make sure the engine coolant in the vehicle is at the specified amount.
(4) Make sure the fuel tank is full.
(5) Make sure the spare tire is in the vehicle.
(6) Make sure the standard tools are in the vehicle.
(7) Make sure nobody is in the vehicle.
(8) Make sure no extra loads are in the vehicle.
(9) Adjust the tire pressures to the specified pressure.
(10) Clean the front glass.

(e) Target sheet creation
(1) Print or copy the illustration below.
Dimension:
NOTICE:
* Make sure that the black areas of the target sheets are not glossy.
* Make sure that the borders of the black and white areas on the target sheets are straight, and are not warped or blurry.
If the print or copy's dimensions are not as specified, adjust settings and reprint or recopy the illustration so that the print or copy's dimensions are as specified.
(f) Target sheet attachment
Text in Illustration
(1) Place the prepared target sheet on a piece of cardboard of the same size with the black area on the top right as shown in the illustration. Then use double-sided tape to fix the target sheet in place.
NOTICE:
Do not attach reflective tape such as scotch tape, etc. to the target face as this may affect target recognition.
(2) Hang a weight with a pointed tip from the center of the target sheet. Then with double-sided tape, attach the target sheet to SST (laser radar adjusting reflector) so that the weight aligns with the mark-off line of SST.
SST : 09870-60000
09870-60010
09870-60020
Text in Illustration
NOTICE:
* Perform this procedure as accurately as possible.
* Attach the target sheet so that it is horizontal with the ground.
(3) Move the reflector up and down to position the center of the target at the height shown in the illustration, and then fix it in place.
Dimension A:
1192 mm (46.9 in.)

(g) Target placement point measurement
NOTICE:
* Do not place black and white patterned objects near the target.
* Face the vehicle toward a wall with no patterns, or make sure the background behind the target has no patterns.
* Perform this procedure as accurately as possible.
* Do not place reflective materials in the area behind the target.
* Make sure there are no patterns on the wall behind the target.
* Make sure the distance between the target and wall is within 3 m (9.84 ft.).
* Make sure the shadow of the target is not on the wall, as a recognition error may occur.
(1) From the center of the front and back bumpers (center of the emblems), hang a weight with a pointed tip, and mark the front bumper center point A and the rear bumper center point B on the ground.
(2) Draw a line that connects points A and B, and extend the line approximately 1.5 m (4.92 ft.) beyond the front of the vehicle.
HINT
Secure the end of a string to point B. Then hold the other end of the string approximately 1.5 m (4.92 ft.) in front of the vehicle, and move it to the left or right to align the string with point A to make a straight line.
(3) Mark point C 1147 mm (45.2 in.) from the front bumper center point A (placement point 1).
(4) From point C, move 300 mm (11.8 in.) towards the front bumper center point A and mark point D.
(5) From point C, place marking tape at a distance of 400 mm (15.7 in.) on the line perpendicular to the line that connects points A and B.
NOTICE:
Place tape so that there is sufficient surface area to clearly and accurately draw line E on the tape in the next step.
(6) Using a measuring tape of 5 m (16.41 ft.) or more and point D as the center point, draw part of a circle with a 500 mm (19.7 in.) radius that overlaps the marking tape (line E).
(7) Mark point F where the following intersect: 1) from point C, the point that is at a distance of 400 mm (15.7 in.) on the line perpendicular to the line that connects point A and point B; and 2) line E.
(8) Extend the measuring tape from point C to point F. Then mark point G 780 mm (30.7 in.) from point C (on the line extending from point C to point F) (placement point 2).
(9) Extend the measuring tape from point F to point C. Then mark point H 780 mm (30.7 in.) beyond point C (placement point 3).
(10) Set a string between points G and H, and use the string to accurately draw a straight line on the ground connecting points G and H (target placement line).
(h) Lane recognition camera sensor height measurement
NOTICE:
* Do not place black and white patterned objects near the target.
* Face the vehicle toward a wall with no patterns, or make sure the background behind the target has no patterns.
