Headlight Aiming

WARNING: This page is about a different car, the 2012 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • If the headlight aiming is adjusted with cargo in the vehicle, it may not adjust correctly. Adjust the headlight aiming with the vehicle under the following conditions:

    • Cargo other than spare tire, jack, and tools not loaded
    • Tire pressure is at specification (See WHEEL AND TIRE SPECIFICATION .)
    • Park the vehicle on level ground
NOTE:
  • The reflectors for the low and high beams are an integrated unit. Therefore, perform the headlight aiming adjustment on only the low beam.
  1. Point the headlight beams to a wall and verify that the headlight beams are as shown in the figure.
