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.

Clean the windshield.
Perform front wheel alignment adjustment.
Note:Perform this procedure as accurately as possible.
Perform rear wheel alignment adjustment.
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

160 mm (6.30 in.)
B
160 mm (6.30 in.)
C
80 mm (3.15 in.)
D
16 mm (0.630 in.)
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.

Cardboard
Attach the target sheet.
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.

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.

Target placement point measurement.
Note: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.).
Do not place black and white patterned objects near the target.
Make sure the target's shadow is not on the wall, as the camera may have a recognition error.
From the center of the front bumper (center of the emblem), hang a weight with a pointed tip, and mark point B on the ground.

Using a piece of string that uses point A as a starting point and that passes through point B, make a straight line on the ground ahead of the vehicle 2 m (6.56 ft.) or more from point B.
Tip:Make sure to secure the string (using tape, etc.) when it is taut.
Lightly flick the string with your fingers several times to confirm that the string is aligned above point B.
Mark point C at a position 640 mm (2.10 ft.) from point B.

Using the string, mark line F at a position 1000 mm (3.28 ft.) from point D.
Using the string, mark line I at a position 1000 mm (3.28 ft.) from point D.
Mark point G at the point where line E and line F intersect (placement point 2).
Mark point J at the point where line H and line I intersect (placement point 3).
Secure a string that connects point G and point J to the ground (target placement line).
