High - Beam Headlamp Bulbs
If you need to replace a high - beam headlamp bulb, do
the following:
1. Remove the headlamp assembly if you need more
hand clearance.
2. Pull up on the wiring harness. This unlocks the bulb.
3. Now you can reach in behind the lamp housing and
pull out the bulb.
4. To replace the bulb, angle the new bulb into the
empty socket.
5. Push the base of the bulb down to lock it into place.
6. If you removed the headlamp assembly, reassemble
it by aligning the pin and tightening the two bolts to
secure it.
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.
