Headlight Aiming

WARNING: This page is about a different car, the 2018 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

If the following servicing is done, perform the headlight aiming adjustment.
- Front combination light replacement
- Suspension replacement and removal/installation, servicing requiring vehicle height to be changed
If servicing was done which changes the vehicle height, perform the headlight auto leveling system initialization first to record the vehicle height under the unloaded condition to the auto leveling control module/AFS control module, then perform headlight aiming. (See HEADLIGHT AUTO LEVELING SYSTEM INITIALIZATION .)

Empty the vehicle except for the spare tire, jack and vehicle tools.
Adjust the tire pressure to the specification. (See WHEEL AND TIRE SPECIFICATION .)
Move the vehicle to level ground.
Verify the headlight auto leveling system operation.
- Sit on the rear seat to verify that the leveling operates.
  - If it operates, go to the next step.
  - If it does not operate, refer to the "THE HEADLIGHT AUTO LEVELING SYSTEM DOES NOT OPERATE IN RESPONSE TO VEHICLE POSTURE". (See THE HEADLIGHT AUTO LEVELING SYSTEM DOES NOT OPERATE IN RESPONSE TO VEHICLE POSTURE [HEADLIGHT AUTO LEVELING SYSTEM] .)
Make an adjustment-use screen as shown in the figure below using double-weight, white paper.
