Fog/Driving Lamp Bulb: Adjustments
FOG LAMP AIMING PROCEDURE
The front fog lamps must be aimed for proper illumination of the road. The front fog lamp aim should be checked when a new front fog lamp assembly is
installed, or if service or repairs in the front end area may have disturbed the front fog lamp mounting.
Preparation Procedure
IMPORTANT: Horizontal aim is not adjustable on this vehicle. Vertical aim is adjusted by an adjusting nut located on the rear of the fog lamp. Prior
to aiming the headlamps, perform the following steps:
1. Completely assemble all of the components on the vehicle.
2. Park the vehicle on a level surface.
3. Stop all unnecessary operations or work on the vehicle that affect the vehicle trim.
4. Close the doors and ensure that the vehicle has no load other than the driver.
5. Stabilize the suspension by rocking the vehicle sideways.
6. Ensure that the fuel level is 1/2 full.
7. Ensure that the tires are inflated to the proper pressure.
8. Ensure that the driver or a similar weight, approximately 75 kg (165 lb), is in the vehicle driver seat.
Aiming Procedure
1. Park the vehicle on a level surface 7.6 m (25 ft) away from a wall or other flat surface.
2. Measure the distance from the floor to the center of the fog lamp (5).
3. Using this measurement, mark the horizontal centerline of the fog lamp (1) on the flat surface directly in front of the vehicle.
4. Turn ON the fog lamps.
5. Reach under the rear lower edge of the front fascia in order to access the fog lamp vertical adjustment screw on the rear of the fog lamp.
6. Adjust the fog lamp so that the top edge of the fog lamp beam pattern is 100 mm (4 in) below the horizontal centerline.
7. Turn OFF the fog lamps.
