Park the vehicle on a level surface where the area in front of the vehicle shown in the illustration is free of metal objects.
Tech Tips
Metal objects with a height of 50 mm (1.97 in.) or less placed within the area shown in the illustration will not affect the adjustment.
Check the levelness of the ground.
*a | 3 m (9.84 ft.) |
Levelness Check Point |
Check the levelness of the ground at the 3 points shown in the illustration.
Place the level on each levelness check point and check that the air bubble of the level is centered.
Adjust the tire inflation pressure to the specified pressure.
Clean the front emblem or millimeter wave radar sensor assembly.
Visually inspect the front of the vehicle.
Tech Tips
Confirm that there is no damage or deformation.
Visually inspect the front bumper assembly, radiator grill and stays.
Tech Tips
Confirm that there is no damage or deformation.
MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY
*a | SST (reflector) |
Adjust SST (reflector) height.
Adjust SST (reflector) so that the center of SST (reflector) is the same height as the millimeter wave radar sensor.
Tech Tips
Make sure to align the center of SST (reflector) with the millimeter wave radar sensor (the center of the emblem).

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.
*a | String | *b | Weight |
*c | Center | *d | Bilateral Symmetry |
Tech Tips
Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.
Hang a weight with a pointed tip from the center of the front emblem, and mark the front center point of the vehicle (point B) on the ground.
*a | String | *b | Weight |
*c | Center | *d | Bilateral Symmetry |
Tech Tips
Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.
Using tape and a string, create a line that connects point B to point A and extends at least 3000 mm (9.84 ft.) beyond the front center point of the vehicle.
*a | String | *b | Tape |
*c | 3000 mm (9.84 ft.) | - | - |
Tech Tips
Make sure the string is taut when securing it with tape.
Lightly flick the string with your fingers several times to confirm that the string is aligned with point B.
Mark point C (SST (reflector) placement position) at a position 3000 mm (9.84 ft.) from point B.
Place SST (reflector) at point C.

MANUALLY CHANGE BEAM AXIS OF MILLIMETER WAVE RADAR SENSOR ASSEMBLY
Note
Manually change the beam axis when error code 12 (radar axis aiming failure upward), 13 (radar axis aiming failure downward) or 1 (no target abnormality) is displayed.
If the beam axis change mechanism is in the most upward or downward position, check for DTCs.
If no DTCs are output, repair or correctly install the front bumper assembly.
Tech Tips
The millimeter wave radar sensor assembly is installed to the front bumper assembly. If the front bumper is misaligned, the beam axis will be misaligned. Therefore, if the front bumper assembly is deformed or damaged, unless the front bumper assembly is replaced, Front Beam Axis Adjustment may not be able to be completed, even if the millimeter wave radar sensor assembly is replaced or its beam axis is adjusted manually.
Remove the engine room side cover.
Remove the cool air intake duct seal.
Turn the bolt to change the beam axis of the millimeter wave radar sensor assembly.
*a | Standard Position | *b | Most Downward Position |
*c | Most Upward Position | - | - |
Vertical axis change | Upward direction: Turn screwdriver to negative (-) side |
Downward direction: Turn screwdriver to positive (+) side |
Tech Tips
Make sure to set the beam axis to the most upward or downward position.
Manually change the beam axis to the position *b (most downward position) when error code 12 (radar axis aiming failure upward) is displayed.
Manually change the beam axis to the position *c (most upward position) when error code 13 (radar axis aiming failure downward) is displayed.
Perform Front Beam Axis Adjustment. (See page 2. MILLIMETER WAVE RADAR SENSOR ASSEMBLY VERTICALLY AND HORIZONTALLY (c) Front Beam Axis Adjustment)
Install the cool air intake duct seal.
Install the engine room side cover.
