The vehicle should: • Be placed so the headlamps are 25 ft. (7.6 m) from a light colored wall. • Have all four tires on a perfectly level surface which is level all the way to the wall. • Be placed so it is perpendicular to the wall. • Not have any snow, ice, or mud on it. • Be fully assembled and all other work stopped while headlamp aiming is being done. Headlamp Aiming The optical headlamp aiming system has been preset at the factory and should need no further adjustment However, If the vehicle is damaged in a crash, the headlamp aim may be affected and adjustment may be necessary. If oncoming vehicles flash their high beams at you, this may also mean the vertical aim needs to be adjusted. • Have a full tank of fuel and one person or 160 lbs (75 kg) on the driver seat. • Have all tires properly inflated. 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. 5-39
