Special Tools Required Radar aimer set 070AJ-SDA0100 Prepare the items shown:

- HDS
- Level (commercially available)

- Tape measure and scale
- String (about 10 m (33 ft) length)
- String with a plumb bob
- Ballpoint pen
- Tape

NOTE: If the millimeter wave radar unit is removed or replaced, or if a millimeter wave radar unit aiming error occurs, re-aim the millimeter wave radar unit. Incomplete aiming, an aiming error, or dust or dirt on the radar unit surface causes the adaptive cruise control (ACC) indicator to come on.

- Millimeter wave radar unit aiming incomplete: DTC 107
- Millimeter wave radar unit aiming error: DTC 63
- Millimeter wave radar unit or emblem surface is contaminated with dust, dirt, ice, or snow: DTC 105

Before Aiming:

- Aiming the millimeter wave radar unit requires the HDS.
- Clean the surface of the millimeter wave radar unit.
- Make sure the vehicle has no aftermarket suspension.
- Make sure all the tyre sizes are correct and that their pressure is correct.
- Make sure the fuel tank is full.
- Make sure the vehicle is not towing, and the front of the vehicle height is normal.
- Remove all baggage from the vehicle except the spare tyre and the tool kit.
- Make sure the steering wheel is directed straight ahead, and do not turn it after setting the vehicle.
- Shift the transmission lever into P or N, and apply the parking brake.
- Make sure the upper grille and the front bumper are installed correctly.
- Park the vehicle on level ground in a wide open space to avoid misadjusting caused by reflecting objects. The space needs to be 10 m (32.8 ft) in front, 4 m (13.1 ft) in width and 1.5 m (4.9 ft) in height.
- If NO TARGET is indicated even when there are no objects 10 m (32.8 ft) in front of the vehicle, check for reflecting objects in front of the vehicle.
- An iron pillar, a shutter, a tool box, a mirror, etc. in front of the vehicle may be detected as a reflector.
- When ‘‘NO TARGET'' is not displayed even after the reflector has been removed from the aiming space (millimeter wave radar detection range), perform aiming after stacking approximately five tyres behind the special tool (radar aimer set). Then ‘‘NO TARGET'' will be displayed comparatively easily.

NOTE: When the millimeter wave radar unit is adjusted on a surface that has more than 1 degree of horizontal slope (drainage slope), the vertical aiming cannot be adjusted correctly. Check the levelness of the surface, and adjust the angle of the millimeter wave radar unit to be parrallel to that of the surface, lay a ruler (at least 12'') or other flat straight object on the surface and put the level on top to confirm the levelness of the surface.
