 Adjust the Headlight
- Park the car on a hard, level surface. Check all tires to make sure they are inflated to at least 32 pounds per square inch, but no more than 38 PSI. Check all fluids, such as the transmission, oil and coolant, to make sure they are filled to proper levels. Remove any heavy items from the vehicle that could cause it to sit unevenly.
- Open the hood and raise the hood prop. Locate the headlight assembly on both sides of the vehicle. Look between the low and high beam headlights on the headlight assembly. Between the headlights, near the bottom of the assembly, you will find an adjustment screw.
- Tighten the adjustment screw completely using a ratchet with a 10 mm socket. Loosen the screw until the headlamp shines at the desired height. You can determine optimal height by placing a white screen 25 feet in front of the vehicle, and adjusting the screw until the brightest illumination is about even with the bottom of the headlight assembly.
- Repeat the process for the other headlight assembly. Close the hood.
