Fog Lamp Aiming (Equinox)
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
Note:
Horizontal aim is not adjustable on this vehicle. Vertical aim is done by an adjusting screw located on the front of the fog lamp. Prior to aiming the headlamps, perform the following steps:
1. Completely assemble all of the components on the vehicle.
2. Place the vehicle on a level surface.
3. Stop all unnecessary operations or work that could affect the ride height of the vehicle.
4. Close the doors and verify that the luggage compartment is empty.
5. Stabilize the suspension by rocking the vehicle sideways.
6. Ensure that the fuel level is 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 lbs) is in the vehicle driver seat.
Aiming Procedure
1. Park the vehicle 7.6 m (25 ft) away from the target screen.
2. Measure from the center of the fog lamp to the ground line. Using this measurement, mark the horizontal centerline (2) of the fog lamp on the target screen directly in front of the vehicle.
3. Turn ON the fog lamps. The top of the fog lamp beam image (4) on the target screen should be 102 mm (4 in) below the center of the fog lamp lens height.
4. Adjust the fog lamp as required, using the adjusting screw (1) on the top of the fog lamp.
5. Turn OFF the fog lamps.
