Lights Headlight Aiming The headlights were properly aimed when your car was new. You should check their aim if you regularly carry heavy items in the trunk or pull a trailer. Each headlight assembly has horizontal and vertical adjustment indicators. These are set to their "0" positions after the headlights are aimed at the factory. To check these settings: 1. Make sure the fuel tank is full. Park the vehicle on level ground. 2. The driver or someone who weighs the same should be sitting in the driver's seat for all checks and adjustments. Load the trunk with the items you normally carry. If you usually pull a trailer, load it as you would normally and attach it to the car. Push down on the front and rear bumpers several times to make sure the car is sitting normally. 3. Open the hood. 4. Check the horizontal angle gauge. The line on the adjustment screw indicator should line up with the mark on the gauge. HORIZONTAL GAUGE CONTINUED Maintenance
