2007 Cadillac Escalade Owner's Manual - Page 442

The vehicle should be properly prepared as follows: • The vehicle should be placed so the headlamps are 25 ft. (7.6 m) from a light colored wall or other flat surface. • The vehicle must have all four tires on a level surface which is level all the way to the wall or other flat surface. • The vehicle should be placed so it is perpendicular to the wall or other flat surface. • The vehicle should not have any snow, ice, or mud on it. • The vehicle should be fully assembled and all other work stopped while headlamp aiming is being performed. • The vehicle should be normally loaded with a full tank of fuel and one person or 160 lbs (75 kg) sitting on the driver's seat. • Tires should be properly inflated. • The spare tire is in its proper location in the vehicle. Headlamp aiming is done with the vehicle's low-beam headlamps. The high-beam headlamps will be correctly aimed if the low-beam headlamps are aimed properly. To adjust the vertical aim, do the following: 1. Open the hood. See Hood Release on page 401 for more information. 2. Locate the center of the projector lens of the low-beam headlamp. 3. Measure the distance from the ground to the center of the projector lens of the low-beam headlamp. Record the distance. 442
