Lights Check the operation of your car's exterior lights at least once a month. A burned out bulb can create an unsafe condition by reducing your car's visibility and the ability to signal your intentions to other drivers. Check the following: Headlights (low and high beam) Parking lights Taillights Brake lights High-mount brake light Turn signals Back-up lights Hazard light function License plate light Side marker lights Daytime running lights (Canadian cars) If you find any bulbs are burned out, replace them as soon as possible. Refer to the chart on page 205 to determine what type of replacement bulb is needed. 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. 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 car 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. Maintenance
