Re: aim headlight
the new bulb should "point" in the same direction as the original -
assuming it is fully - properly seated -
it is possible you missed one of the three tabs - and the bulb is sitting wrong -
what is the small gauge on top for
originally - it was a bubble-level - filled with a green liquid -
this - from page 6-40 of the Owners Manual -
Your vehicle has a visual optical headlamp aiming system
equipped with horizontal aim indicators. The aim has been
preset at the factory and should need no further adjustment.
This is true even though your horizontal aim indicators may
not fall exactly on the “0” (zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers flash their
high beams at you (for vertical aim). If you believe your
headlamps need to be re-aimed, we recommend that you
take your vehicle to your dealer for service. However, it
is possible for you to re-aim your headlamps as
described in the following procedure.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall or other
The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.
The vehicle should be placed so it is perpendicular to
the wall or other flat surface.
The vehicle should not have any snow, ice or mud
attached to it.
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs. (75 kg) on the
Tires should be properly inflated.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.
The headlamp aiming devices are under the hood near
If you believe your headlamps need horizontal
(left/right) adjustment, follow the horizontal aiming
procedure. If you believe your headlamps need only
vertical (up/down) adjustment, follow only the vertical
Adjustment screws can be turned with an E8 Torx
socket or T15 Torx screwdriver.
