* Make sure that 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 (4.922 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 1.5 m (4.922 ft.) x 3 m (9.843 ft.) area in front of the vehicle.
* Perform the inspection in a bright area.
(a) Prepare for beam axis learning.
(1) Move the vehicle to a level surface.
(2) Make sure the engine oil in the vehicle is at the specified level.
(3) Make sure the engine coolant in the vehicle is at the specified level.
(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 windshield.
(11) If the lens of the lane recognition camera sensor is dirty, apply a small amount of lens cleaner to a clean and soft cloth, and clean the lens.
(b) Perform the front wheel alignment adjustment.
(1) Perform the front wheel alignment adjustment Front Wheel Alignment.
NOTICE:
Perform this procedure as accurately as possible.
(c) Perform the rear wheel alignment adjustment.
(1) Perform the rear wheel alignment adjustment Rear Wheel Alignment.
NOTICE:
Perform this procedure as accurately as possible.
(d) Create a target sheet.
(1) Print or copy the illustration. Check that the dimensions are +/- 5 mm (0.197 in.) of the ones in the table below.
Dimension:
NOTICE:
* 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.
(1) If the print or copy's dimensions are not as specified, adjust settings and reprint or recopy so that the print or copy's dimensions are as specified.
(e) Attach the target sheet.

(1) Place the prepared target sheet on a piece of cardboard of the same size, position 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 transparent adhesive 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.
(3) Attach the target sheet to SST (radar adjusting reflector) with double-sided tape so that the tip of the weight aligns with the mark-off line.

NOTICE:
* Perform this procedure as accurately as possible.
* Attach the target sheet so that the bottom edge is parallel with the ground.
(4) Move the reflector up and down to position the center of the target at the height shown in the illustration, and fix it in place.
Dimension A:
1016 mm (3.333 ft.)

NOTICE:
Perform this procedure as accurately as possible.
(f) Measure the target placement point.
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 the target is within 3 m (9.843 ft.) of the wall.
* Make sure the target's shadow is not on the wall, as the camera may have a recognition error.
(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 on the ground as point A and the rear bumper center on the ground as point B.
Text in Illustration
(2) Draw a line that connects points A and B, and extend the line approximately 2 m (6.562 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 2 m (6.562 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 1145 mm (3.757 ft.) from the front bumper center point A (this is placement point 1).
Text in Illustration
(4) From point C, move 300 mm (11.811 in.) toward the front bumper center point A and mark point D.
(5) From point C, place marking tape at a point 400 mm (1.312 ft.) perpendicular to the line that connects points A and B.
NOTICE:
Place the tape so that there is plenty of surface area along the perpendicular line.
(6) Using a measuring tape of 5 m (16.41 ft.) or more, with point D as the center point, draw the part of a 500 mm (1.641 ft.) circle that overlaps the marking tape (line E).
(7) Mark point F where the following intersect: 1) from point C, the point that is 400 mm (1.312 ft.) perpendicular from the line that connects point A and B; and 2) line E.
HINT
The purpose of the above step is to ensure that point F is placed exactly perpendicular to the line that passes through points A and B.
(8) Set the measuring tape from point C to F. Then mark point G 780 mm (2.559 ft.) from point C (on a line extending from point C through F) (this is placement point 2).
(9) Set the measuring tape from point F to C. Then mark point H 780 mm (2.559 ft.) beyond point C (this is placement point 3).
(10) Set a string between points G and H, and draw a line on the ground (target placement line).
(g) Measure the lane recognition camera sensor height.
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 the target is within 3 m (9.843 ft.) of the wall.
* Make sure the target's shadow is not on the wall, as this may cause the camera to have a recognition error.
(1) Measure the distance (X mm or in.) from the ground to point H for the front left wheel arch.
(2) Measure the distance (Y mm or in.) from the ground to point H' for the front right wheel arch.
(3) The average of the 2 distances (X mm or in, Y mm or in.) plus 681 mm (2.234 ft.) is the height of the lane recognition camera sensor.
(h) Memorize camera/target position.
NOTICE:
* Close all doors.
* Perform the procedure with no one in the vehicle.
* During the procedure, do not lean on the vehicle.
* Turn on the clearance lights.

2. ROAD TEST
HINT
The system may not operate normally under the following conditions:
* The lane markers are difficult to see because they are blurry, backlit, or because of bad weather or puddles.
* There are ruts in the snow on a road, or strips of snow on the road.
* There are streaks of light from street lights or headlights of oncoming vehicles that are reflected by a wet road.
* There are patches of sunlight and shade on the road.
* There is a stretch of guardrail or curb.
* There are traces of old lane markers on the road.
* The width of the lane markers is less than 150 mm (5.91 in.).
* The vehicle-to-vehicle distance is extremely short.
* The temperature of the lane recognition camera sensor body is -20°C (-4°F) or less or 60°C (140°F) or more.
(a) Road Test
CAUTION:
Drive very carefully.
NOTICE:
Make sure to perform a road test and check for proper operation of the system after performing beam axis learning.
(1) Turn the lane keeping assist main switch on, and turn the cruise control off using the cruise control main switch (this actuates the lane departure warning function).
NOTICE:
Perform the road test with the lane departure warning function activated.
HINT
The lane keeping assist function is activated when the lane keeping assist main switch is turned on while the cruise control system is operating and the vehicle is in vehicle-to-vehicle distance control mode.
(2) Drive the vehicle near the center marker at a speed of 60 km/h (37 mph ) or more for 3 seconds or longer on a safe straight road with white or yellow center and side lane markers.
NOTICE:
* Select an appropriate road or freeway where the vehicle can be safely driven at a speed of 60 km/h (37 mph ) or more. The road that is selected should not be in use by pedestrians or bicycles.
* Perform the road test on a flat straight road.
* Exercise caution when steering the vehicle.
* Avoid abrupt steering inputs.
* Obey the speed limit.
HINT
* The lane recognition camera sensor can recognize dashed lane markers (the distance between markers should be 12 m (39.372 ft. ) or less).
* Lane departure warning mode operates when the vehicle speed is between 48 and 200 km/h (30 and 125 mph ).
(3) Check that the recognition indicator on the combination meter display comes on.
HINT
If the indicator does not come on, check the following:
* Installation condition of the lane recognition camera sensor
* Wheel alignment
* Location of the target
