If you drive a 2019 Jeep Grand Cherokee, you know how important good visibility is, especially in foggy or rainy weather. Many drivers are unsure how to use their fog lights correctly. These special lights can make a big difference in safety, but only if you know when and how to turn them on. Let’s walk through all you need to know about using fog lights on your 2019 Grand Cherokee, step by step.
Understanding Fog Lights On The 2019 Jeep Grand Cherokee
Fog lights are different from your regular headlights. They are designed to shine low and wide, helping you see the edges of the road in bad weather.
On the 2019 Jeep Grand Cherokee, the fog lights are mounted in the lower part of the front bumper.
They only work when your low beam headlights are on not the high beams.
Many owners overlook that the fog light controls are not on a separate switch but are built into the headlight stalk. If you’ve never used them before, their location can be confusing.
Steps To Turn On Fog Lights: 2019 Jeep Grand Cherokee
Let’s break down the process in simple steps:
1. Turn On Your Vehicle
Start your Jeep and ensure it’s in PARK mode for safety.
2. Locate The Headlight Control Stalk
Look to the left side of your steering wheel. You’ll see a stalk (lever) that controls your headlights and turn signals.
3. Turn On Low Beam Headlights
Rotate the outer ring of the stalk from “OFF” to the headlight symbol (two beams facing downwards). The fog lights will only operate with the low beams.
4. Activate The Fog Lights
Push the inner button or ring on the stalk (sometimes marked with a fog light symbol an oval with three horizontal lines). You should hear a click, and a green fog light icon will appear on your dashboard.
5. Check The Indicator
Look for the green fog light symbol on your instrument cluster. This confirms the fog lights are on.
6. Turn Off When Not Needed
To switch them off, press the same button again. The dashboard icon will go off.
Quick Reference Table: Fog Light Operation
Here’s a summary of the controls you’ll use:
| Step | Action | Control Location |
|---|---|---|
| 1 | Start the vehicle | Ignition (dashboard) |
| 2 | Switch on low beam headlights | Left stalk, outer ring |
| 3 | Press fog light button | Left stalk, center/inner button |
| 4 | Confirm dashboard indicator | Instrument cluster |
Important Safety Tips
Fog lights are powerful, but they should not be used all the time. Use them only in low-visibility conditions, such as:
- Thick fog
- Heavy rain
- Snowstorms
- Dusty roads
Using fog lights in clear weather can blind other drivers and is illegal in some places. Always turn them off when visibility improves.
Common Mistakes To Avoid
Many drivers make simple mistakes when using fog lights. Watch out for these:
- Trying to use fog lights with high beams: The 2019 Grand Cherokee disables fog lights when high beams are on.
- Forgetting to turn them off: Leaving fog lights on in good weather can annoy other drivers and drain your battery if the engine is off.
- Not checking for the dashboard icon: Always confirm the green symbol is lit to be sure fog lights are on.
Feature Comparison: Fog Lights Vs. Headlights
Here’s how fog lights are different from your main headlights:
| Feature | Fog Lights | Headlights |
|---|---|---|
| Beam Angle | Wide and low | Narrow and long |
| Best Use | Fog, rain, snow | Normal driving |
| Location | Bumper (low) | Front grille area |
| Control | Stalk button | Stalk ring |
Troubleshooting Fog Lights
Sometimes, your fog lights may not work even if you follow the steps. Here’s what to check:
- Blown fuse: Check your owner’s manual for the fog light fuse location.
- Burned-out bulb: If one side is out, the bulb may need replacement.
- Wiring issues: Rare, but possible if the lights flicker or don’t respond.
- Settings: Make sure the headlights are set to low beam, not AUTO or high beam.
If you’re not comfortable with electrical checks, visit your Jeep dealer or a trusted mechanic.
Practical Insights Most Owners Miss
- Fog lights do not adjust automatically. Unlike some headlights, your fog lights will not turn on by themselves, even in AUTO mode. You must manually activate them.
- Aftermarket changes may affect controls. If your Jeep has a custom bumper or aftermarket lighting, the fog light controls might behave differently or need re-wiring. Always check with the installer.
When To Use And Not Use Fog Lights
Use fog lights only when visibility drops below 100 200 feet due to weather. In light mist or drizzle, headlights alone are safer.
Misuse can get you a ticket in some states.
Quick Maintenance Table: Fog Light Care
Regular fog light care helps them last longer:
| Task | How Often | Why |
|---|---|---|
| Clean lenses | Monthly or after storms | Removes dirt for brighter light |
| Check bulbs | Every 6 months | Replace burned-out bulbs |
| Inspect fuse | Yearly | Prevents sudden failure |
