Warning

•  Radiofrequency radiation exposure information:

?  This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.

?  This equipment should be kept with minimum distance of 20 cm {7.9 in} between the radiator (antenna) and your body at all times during adjustment.

?  This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

•  If the radar unit aiming adjustment is not completed, the Mazda radar cruise control (MRCC) system, Distance recognition support system (DRSS), and Smart brake support (SBS) will not operate normally which could lead to an unexpected accident. Therefore, when performing the following work, always perform the aiming adjustment so that the Mazda radar cruise control (MRCC) system, Distance recognition support system (DRSS), and Smart brake support (SBS) operate normally.

1.  Park the vehicle on level ground.

Caution

•  If the vehicle and reflector are set at different heights or different angles, accurate adjustment cannot be performed.

•  Level ground conditions must be within 1 degree for the front and back, and right and left.

•  Perform the work in an area where 8 m {26 ft} or more of space from the vehicle front and 4 m {13 ft} or more of width are available.

•  Perform the aiming adjustment in a place where there is no obstruction up to 1.2 m {3.9 ft} or more from the road surface at approx. 8 m {26 ft} from vehicle front.

•  Remove cargo from the cabin and trunk compartment so that the vehicle is in an unloaded condition.

•  Adjust the tire pressure of each tire to the specified value.

•  Do not let foreign material (metal, plastic material) get into the aiming implementation area to prevent radio wave interference.

•  Do not move or shake the vehicle during aiming adjustment (such as riding in or opening a door).

•  Remove dust or dirt from the radiator grille ornament.

•  Do not turn the power off during the aiming adjustment.

•  The voltage supplied to the radar unit must be 9.5—15.5 V.

•  The aiming adjustment must be performed under approx. -30—60 °C {-22—140 °F} conditions.

Note

•  The center of the brand emblem indicates the center position of the vehicle.

3.  Adjust the SST (plum-bob) so that it is aligned with the center of the brand emblem, determine the center position at the rear of the vehicle, and mark the center position (point B) on the floor surface.

Note

•  The center of the brand emblem indicates the center position of the vehicle.

4.  Secure the end of the leveling line over point B.

Note

•  Use a commercially-available leveling line.

5.  Pull the unsecured end of the leveling line over the vehicle and to the front and adjust it so that it passes over point A.

6.  Mark the line (position A) at the point 5 m {16 ft} from point A and in the direction forward of the vehicle.

Note

•  If the leveling line is secured at the vehicle front center point (point A), the leveling line may deviate. Therefore, secure the leveling line in the order of point B, point C, and point A.

7.  Install the SST (reflector and plum bob) to the SST (tripod).

8.  Adjust so that the height of the SST (reflector) from the floor surface is 710 mm {28.0 in}.

Note

•  A commercially-available tripod equipped with a level can be substituted for the SST (stand).

10.  Set the SST (stand) with the SST (plum-bob) and the marking aligned.

Note

•  Visually verify that the reflection surface of the reflector faces the vehicle.

11.  Visually inspect the surfaces of the radar unit and the radiator grille ornament for the following:

•  Dirt is adhering to radar unit surface

•  Dirt is adhering to radiator grille ornament surface

•  Foreign material (reflective object) is adhering to radar unit

•  Foreign material (reflective object) is adhering to radiator grille ornament surface

12.  Connect the M-MDS to the DLC-2.

Caution

•  If the engine is started, the aiming may not be performed correctly due to oscillation. Perform the aiming with the engine stopped.

13.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

(1)  Select "Electrical".

(2)  Select "SBS/MRCC".

(3)  Select "Radar Aiming".

14.  Perform the aiming adjustment following the instructions on the screen.

15.  If "Aiming has been unsuccessful." Is displayed on the screen, repair according to the error code in the following chart.

•  If verification and repair are completed, perform the aiming adjustment again.
