Headlamp Aiming
Your vehicle has a headlamp system equipped with
horizontal and vertical aim indicators. The aim has
been pre
-
set at the factory and should need no further
adjustment. This is true even though your vertical and
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 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 it to your dealer
for service; however, it is possible for you to re
-
aim your
headlamps as described in the following procedure.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
To check the aim, the vehicle should be properly
prepared as follows:
D The headlamps must be off for one hour prior to
aiming and must remain off during this procedure.
D The vehicle must have all four tires on a perfectly
level surface.
D If necessary, pads may be used on an uneven surface.
D The vehicle should not have any snow, ice or mud
attached to it.
D The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
D There should not be any cargo or loading of the
vehicle, except it should have a full tank of fuel and
one person or 160 lbs. (75 kg) on the driver’s seat.
D Close all doors.
D Tires should be properly inflated.
D Rock the vehicle to stabilize the suspension.
