FRONT CAMERA ADJUSTMENT

CAUTION / NOTICE / HINT

Note

When replacing the windshield glass of a vehicle equipped with a forward recognition camera, make sure to use a Lexus genuine part. If a non-Lexus genuine part is used, the forward recognition camera may not be able to be installed due to a missing bracket, or the road sign assist system, LKA/LDA system, forward recognition camera system, dynamic radar cruise control system, pre-crash safety system. automatic high beam system or adaptive high beam system may not operate properly due to a difference in the transmissivity of the windshield glass or the shape of the black ceramic border.

      Park the vehicle on a level surface.

      Note


      • Make sure there are no black and white patterned objects in front of the vehicle.

      • Perform the following procedures indoors.

      • Perform the following procedures in an area with no wind.

      • Perform the following procedures in a bright area.

        Tech Tips

        Make sure that the area shown in the illustration in front of the vehicle is free of reflective or shiny objects.

    2. Check that the headlights are turned off.

    3. Adjust the tire inflation pressure to the specified pressure. Click here

    4. Clean the windshield glass.

  2. PERFORM FORWARD RECOGNITION CAMERA LEARNING


    1. Create a target sheet.


      1. Print the illustration.

        Text in Illustration
        *a 18 mm (0.709 in.)
        *b 90 mm (3.54 in.)
        *c 180 mm (7.09 in.)

        Check that the dimensions are within the values shown in the illustration.

        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.

        Tech Tips

        If the dimensions of the created target sheet are not within +/- 5 mm (0.197 in.) of the specified values, adjust the printer settings and reprint the target sheet so that the dimensions are as specified.

    2. Attach the target sheet.

        *a Target Sheet
        *b Cardboard

        Cut a piece of cardboard to the same size as the target sheet.

      2. Place the target sheet on the cardboard with the black area at the top right as shown in the illustration, and securely attach the target sheet using double-sided tape.

        Note

        Do not attach reflective materials, such as clear adhesive tape, to the target sheet surface as this may affect target recognition.

        *a String
        *b Weight
        *c Mark-off Line

        Hang a weight with a pointed tip from the top center of the target sheet as shown in the illustration.

        SST
        09870-60000   ( 09870-60010, 09870-60020 )
      4. Using double-sided tape, attach the target sheet to SST (reflector) so that the weight is aligned with the mark-off line of SST.

        Tech Tips

        Make sure that the points (A), (B) and (C) of the target sheet are aligned with the string.

        *a 1350 mm (53.15 in.)

        Move SST (reflector) up or down so that the center of the target sheet is at the height shown in the illustration, and secure SST (reflector) in place.

        Tech Tips

        If the center of the target sheet is not within +/- 6 mm (0.236 in.) of the height specified, adjust the position of SST (reflector) so that the height is as specified.

    3. Determine the target placement position.

      Note


      • Make sure the background behind the target has no patterns.

      • Make sure that there are no reflective or shiny objects around the target.

      • Make sure that the shadow of the target is not cast onto a wall as this may cause a target recognition error.


      1. Hang a weight with a pointed tip from the center of the rear emblem, and mark the rear center point of the vehicle (point A) on the ground.
