Headlamp Alignment - Aston Martin DB 9 2010 Manual

Headlamp Alignment

Headlamp aim check and
adjustment must be
completed with the vehicle
parked on a flat surface with
the headlamps facing a
vertical wall at a distance of
25 ft (7.6 m) to the outboard
internal lens, with no
additional loads in the
vehicle.
Check
1. Set the dipped beam to ON, ensuring that only the outer lamp
each side is ON.
2. Measure the height of the left side of the beam pattern
projected onto the wall. This should measure 23.19 in. (0.60 m)
from the ground for a correctly aimed lamp. This must be
completed for both right and left headlamps.
Adjustment
Warning: Never allow anyone to turn the steering wheel
whilst working in the road wheel arch.
Warning: Never remove the bulb access caps without
reading the bulb replacement instructions.
Should either headlamp require adjustment:
1. Remove the access panel. Turn the
retaining screw 90°
counterclockwise using a flat
bladed screw driver or coin and
pull out the access panel.
