Make sure there are no black and white patterned objects in front of the vehicle.
Be sure to perform the measurement on a level surface that is free of obstacles and extends 1.5 m (4.92 ft.) or more in front of the vehicle.
Make sure that there is no wind when performing the measurement.
Check that there are no reflective materials in the surroundings or on the ground within a 3 m (9.84 ft.) x 3 m (9.84 ft.) area in front of the vehicle.
Perform the inspection in a bright area.
Prepare for beam axis learning.
Move the vehicle to a level surface.
Make sure the engine oil in the vehicle is at the specified level.
Make sure the engine coolant in the vehicle is at the specified level.
Make sure the fuel tank is full.
Make sure the spare tire is in the vehicle.
Make sure the standard tools are in the vehicle.
Make sure nobody is in the vehicle.
Make sure no extra loads are in the vehicle.
Adjust the tire pressures to the specified pressure.
Clean the windshield.

Note
Perform this procedure as accurately as possible.
Create a target sheet.
Print or copy the illustration . Check that the dimensions are within +/- 5 mm (0.197 in.) of the ones in the table below.
Dimension | ||||||||||
---|---|---|---|---|---|---|---|---|---|---|
|
Note
Make sure that the black areas of the target sheet are not glossy.
Make sure that the borders of the black and white areas on the target sheet are straight, and are not warped or blurry.
If the dimensions of the print or copy are not as specified, adjust settings and reprint or recopy so that the dimensions are as specified.
Attach the target sheet.
*1 | Target Sheet |
*2 | Cardboard |
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 secure the target sheet in place.
Note
Do not attach reflective tape, such as transparent adhesive tape, etc. to the target face, as this may affect target recognition.
*a | Pointed Tip Weight |
*b | Mark-off Line |
Hang a weight with a pointed tip from the center of the target sheet. Then, with double-sided tape, attach the target sheet to the reflector so that the weight aligns with the mark-off line of SST (laser radar adjusting reflector).
Note
Perform this procedure as accurately as possible.
Attach the target sheet so that it is horizontal with the ground.
Move the reflector up and down to position the center of the target at the height shown in the illustration and secure it in place.

1270 mm (4.17 ft.) |
Note
Perform this procedure as accurately as possible.
Measure the target placement point.
Note
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 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 the camera may have a recognition error.
*1 | Line |
*a | Approximately 2 m (6.56 ft.) |
*b | Point A |
*c | Point B |
From the center of the front and rear 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.
Draw a line that connects points A and B, and extend the line approximately 2 m (6.56 ft.) beyond the front of the vehicle.
Tech Tips
Secure the end of a string to point B. Then hold the other end of the string approximately 2 m (6.56 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.
Mark point C (placement point 1) 1120 mm (3.67 ft.) from the front bumper center point A.
*a | Point A | *b | Point B |
*c | Point C (Placement Point 1) | *d | Point D |
*e | Line E | *f | Point F |
*g | Place tape (gray area) approx. 400 mm from point C | *h | Point G (Placement Point 2) |
*i | Point H (Placement Point 3) | *j | Lane Departure Warning Camera Position |
From point C, move 300 mm (11.8 in.) towards the front bumper center point A and mark point D.
From point C, place marking tape at the point 400 mm (1.31 ft.) perpendicular to the line that connects points A and B.
Note
Place the tape so that there is plenty of surface area along the perpendicular line.
Using a measuring tape of 500 mm (1.64 ft.) or more, and point D as the center point, draw the part of a 500 mm (1.64 ft.) circle that overlaps the marking tape (line E).
Mark point F at the point where line E and the point that is 400 mm (1.31 ft.) from point C, and is perpendicular to the line that connects point A and B, intersect.
Set the measuring tape from point C to F. Then mark point G (placement point 2) 780 mm (2.56 ft.) from point C (line extending from point C to F).
Set the measuring tape from point F to C. Then mark point H (placement point 3) 780 mm (2.56 ft.) beyond point C.
Set a string between points G and H, and draw a line on the ground (target placement line).
Memorize camera/target position.
Note
Close all doors.
Perform the procedure with no one in the vehicle.
During the procedure, do not lean on the vehicle.
Do not turn on the headlights.
