How to Adjust the Headlights in a Jeep Grand Cherokeeby Contributor
Oncoming drivers typically only flash their lights at you if your headlights seem to be on high or to warn you of a hazard like a cop or a deer in the road up ahead. If you can't seem to come across any hazards, it probably means you need to adjust the headlights on your Jeep Grand Cherokee.
Pay attention to your normal driving conditions including the amount of cargo weight, the pressure in your tires and the level of your fuel tank. You want to use the same conditions for your Jeep Grand Cherokee when you adjust the headlights.
Park your SUV 10 to 15 feet behind a parked car. If you prefer, you can also use a wall or screen and measurements from the headlights to determine where the trajectory should hit on a properly adjusted SUV.
Allow the suspension to settle. You can gently rock the SUV a few times by pushing down on the bumper.
Remove the retaining screws for the turn signal mounting and gently remove the turn signal mounting and the bezel to expose the adjustment screws. Jeep puts the adjustment screws in the center of the mounting screws for the headlight, so make sure you don't accidentally loosen the headlight assembly.
Turn your headlights on. You may want to use the emergency brake to prevent any accidents.
Adjust the horizontal or vertical screws for each headlight. Keep an eye on the item you decided to use as a reference. If you use a parked car, you want the headlights to hit the bumper. You need to use a Phillips screwdriver, Torx tool head or Allen wrench to move the adjustment screws.
Allow a 2-inch variance from the center of the mark to the center of the trajectory path. You may only be able to get either the high beams or the low beams to hit the center. Pick the one you use the most often.
- The adjustment screws only change the trajectory for the headlight-they don't focus the light.
- Export models use an automatic leveling system with a gauge. To adjust, set the gauge to "0."
