yellowblue 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. 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. 3. Now you can reach in behind the lamp housing and pull out the bulb. 6-35
