How to Reset Low Washer Fluid Light Infiniti Qx80

Resetting the low washer fluid light on your Infiniti QX80 is easier than you think. This guide walks you through every step—from checking fluid levels to using the dashboard controls—so you can clear the warning and drive safely without confusion.

Key Takeaways

• Check washer fluid level first: Always confirm the reservoir is full before attempting a reset to avoid repeated warnings.
• Use the steering wheel controls: The reset process involves the trip odometer and menu buttons on the steering wheel.
• Turn ignition to “ON” position: The engine doesn’t need to be running, but the dashboard must be powered.
• Navigate to “Washer Fluid” in settings: Access the vehicle settings menu to find the reset option.
• Hold the reset button for 3–5 seconds: This clears the warning light and resets the system.
• Test the washer spray after reset: Ensure the system works properly and the light stays off.
• Use correct fluid type: Always use washer fluid rated for your climate to prevent freezing or clogging.

Why the Low Washer Fluid Light Comes On

The low washer fluid light in your Infiniti QX80 is designed to keep you safe. It alerts you when the windshield washer fluid level drops below a certain point. This small warning light on your dashboard might seem minor, but it plays a big role in maintaining visibility while driving.

Dirt, bugs, rain, and road grime can quickly obscure your windshield. Without enough washer fluid, you can’t clean it effectively. That’s why Infiniti built this reminder into the QX80. It’s not just about convenience—it’s about safety.

The system uses a sensor in the washer fluid reservoir. When the fluid level gets low, the sensor triggers the warning light. This usually happens after several uses of the washer spray. If you ignore it, you might run out of fluid when you need it most—like during a sudden downpour or when driving through a dusty area.

Some drivers think the light will go away on its own after refilling the fluid. But that’s not always true. In many Infiniti models, including the QX80, the system requires a manual reset. That’s why even after topping off the fluid, the light may stay on. This guide will show you exactly how to fix that.

Common Causes of the Warning Light

There are a few reasons why the low washer fluid light might appear:

• Low fluid level: The most common cause. You’ve used up the fluid and haven’t refilled it yet.
• Faulty sensor: Over time, the sensor in the reservoir can get clogged or malfunction, giving false readings.
• Evaporation in hot weather: In summer, washer fluid can evaporate faster, especially if the reservoir isn’t sealed properly.
• Leaking reservoir or hose: A small crack or loose connection can cause fluid to leak out unnoticed.
• Incorrect fluid type: Using water instead of proper washer fluid can lead to freezing or sensor issues.

Before resetting the light, it’s important to check the actual fluid level. Open the hood and locate the washer fluid reservoir. It’s usually a white or translucent plastic tank with a blue cap. You should be able to see the fluid level through the side. If it’s below the “MIN” line, fill it up with the correct type of washer fluid.

Why a Manual Reset Is Often Needed

Unlike some car systems that reset automatically, the Infiniti QX80’s washer fluid warning often requires a manual reset. This is because the system doesn’t just detect fluid level—it tracks usage and expects a reset after refilling.

Think of it like a digital counter. Every time you use the washer, the system logs it. When the fluid gets low, it triggers the light. But even after you refill, the system doesn’t “know” unless you tell it. That’s where the reset comes in.

This design helps prevent false alarms. If the light turned off automatically after a refill, it might not alert you again until the fluid was dangerously low. By requiring a manual reset, Infiniti ensures you’re actively maintaining the system.

It’s a small step, but it makes a big difference in long-term reliability.

Tools and Supplies You’ll Need

You don’t need any special tools to reset the low washer fluid light on your Infiniti QX80. Everything you need is already in your car. But having the right supplies on hand makes the process smoother.

Basic Tools

• Steering wheel controls: You’ll use the trip odometer button and menu navigation buttons on the left side of the steering wheel.
• Ignition key or push-button start: You need to turn the ignition to the “ON” position without starting the engine.
• Washer fluid: Make sure you have the correct type for your climate. Summer, winter, or all-season fluid—choose based on your region.

Recommended Washer Fluid Types

Using the right washer fluid is important. Water might seem like a cheap alternative, but it can freeze in cold weather or leave mineral deposits that clog the nozzles.

• All-season washer fluid: Works in most climates. Good for temperatures above 20°F (-7°C).
• Winter washer fluid: Contains antifreeze agents. Use when temperatures drop below freezing.
• Bug-resistant formula: Helps break down dried insects on the windshield. Great for highway driving.
• De-icer fluid: Designed to melt ice on the windshield. Use in extreme cold.

Avoid using household cleaners, glass cleaners, or detergents. These can damage the reservoir, hoses, or pump. Stick to fluids labeled for automotive use.

Optional but Helpful Items

• Funnel: Helps pour fluid without spilling.
• Clean cloth: Wipe up any spills to prevent damage to paint or engine components.
• Flashlight: Helps you see the reservoir and fluid level in low light.

Having these items ready saves time and prevents messes. Now that you’re prepared, let’s move on to the reset process.

Step-by-Step Guide to Reset the Low Washer Fluid Light

Resetting the low washer fluid light on your Infiniti QX80 is a straightforward process. Follow these steps carefully, and you’ll have the warning light turned off in under two minutes.

Step 1: Turn the Ignition to “ON”

First, get into your QX80 and sit in the driver’s seat. You don’t need to start the engine. Instead, turn the ignition to the “ON” position. If you have a key, turn it to the second position (before starting). If you have a push-button start, press the button once without pressing the brake pedal.

You’ll see the dashboard lights up. The instrument cluster will display various indicators, including the low washer fluid light if it’s on. This confirms the system is powered and ready for input.

Step 2: Locate the Trip Odometer Button

On the left side of your steering wheel, you’ll find a set of buttons. Look for the one labeled “TRIP” or marked with a small odometer icon. This button cycles through different trip meter readings.

Press this button repeatedly until you see “Washer Fluid” or “Washer” appear on the display. Depending on your model year, the exact wording may vary. Some QX80s show it under “Vehicle Settings” or “Maintenance.”

Step 3: Enter the Menu

Once you’ve found the washer fluid option, press and hold the “TRIP” button for about 3 to 5 seconds. You should see the display change, indicating you’ve entered a submenu.

On some models, you may need to use the “INFO” or “MENU” button instead. If the “TRIP” button doesn’t work, try pressing the “INFO” button on the steering wheel to access the main menu, then navigate to “Settings” > “Vehicle” > “Washer Fluid.”

Step 4: Reset the Warning

When you’re in the correct menu, you’ll see an option to reset the washer fluid level. It might say “Reset Washer Fluid Level” or simply “Reset.”

Press and hold the “TRIP” button (or the “OK” button if using the menu navigation) for 3 to 5 seconds. The display should flash or show a confirmation message like “Reset Complete” or “Washer Fluid Reset.”

At this point, the low washer fluid light on your dashboard should turn off. If it doesn’t, double-check that you’re in the right menu and try again.

Step 5: Turn Off the Ignition

Once the reset is complete, turn the ignition back to the “OFF” position. Remove the key or press the start button again to power down the system.

Wait about 10 seconds, then turn the ignition back to “ON” to confirm the light stays off. If it does, you’ve successfully reset the system.

Step 6: Test the Washer System

Now that the light is off, test the washer system to make sure everything is working.

Pull the windshield washer lever toward you. You should hear the pump activate and see fluid spray onto the windshield. If nothing happens, check the fluid level again or inspect for clogs in the nozzles.

If the light comes back on immediately after testing, there may be an issue with the sensor or a leak in the system. In that case, further inspection may be needed.

Troubleshooting Common Issues

Sometimes, the reset process doesn’t work as expected. Here are some common problems and how to fix them.

The Light Won’t Turn Off After Reset

If the low washer fluid light remains on after following the steps, there could be a few reasons:

• Fluid level is still low: Double-check the reservoir. Even a small dip below the sensor can trigger the warning.
• Sensor is dirty or stuck: Over time, dirt or dried fluid can coat the sensor. Try cleaning the reservoir and sensor with a soft cloth.
• Electrical issue: A loose wire or faulty connection could prevent the system from recognizing the reset. This may require a visit to a technician.

The Menu Option Isn’t Visible

If you can’t find the “Washer Fluid” option in the menu, your model year might use a different navigation path. Try these alternatives:

• Press the “INFO” button and go to “Settings” > “Vehicle” > “Maintenance.”
• Look for “Service” or “Reminder” options that include washer fluid.
• Consult your owner’s manual for the exact menu layout.

Some older QX80 models may not have a digital reset option. In that case, the light may turn off automatically after several uses of the washer system.

The Washer Pump Doesn’t Work

If the light resets but the washer doesn’t spray, the issue might be mechanical:

• Clogged nozzles: Use a pin or needle to clear debris from the spray holes.
• Faulty pump: Listen for a humming sound when you activate the washer. No sound could mean a dead pump.
• Blown fuse: Check the fuse box under the dashboard or hood. Replace any blown fuses.

Fluid Leaks Under the Car

If you notice fluid dripping after refilling, inspect the reservoir and hoses:

• Check for cracks in the plastic tank.
• Ensure the cap is tightly sealed.
• Look for loose or cracked hoses near the pump.

A small leak can cause the fluid to drain quickly, triggering the warning light again.

Maintenance Tips to Prevent Future Warnings

Keeping your washer fluid system in good shape helps avoid repeated warnings and ensures clear visibility.

Check Fluid Level Monthly

Make it a habit to check the washer fluid level every time you fill up your gas tank. This only takes a few seconds and can prevent unexpected issues.

Use Quality Washer Fluid

Invest in a good brand of washer fluid. Cheap fluids may contain impurities that clog the system or damage components over time.

Clean the Reservoir Annually

Once a year, drain the old fluid and rinse the reservoir with clean water. This removes sediment and prevents sensor buildup.

Inspect Nozzles Regularly

Every few months, check the spray pattern. If it’s weak or uneven, clean the nozzles with a pin or compressed air.

Replace the Cap if Damaged

A cracked or loose cap can let dirt in and cause evaporation. Replace it if it doesn’t seal properly.

Winter Preparation

In cold climates, switch to winter washer fluid before temperatures drop. This prevents freezing and ensures the system works when you need it.

When to See a Mechanic

Most issues with the low washer fluid light can be resolved at home. But sometimes, professional help is needed.

Persistent Warning Light

If the light keeps coming back even after refilling and resetting, there may be a deeper issue. A mechanic can diagnose sensor problems, wiring faults, or pump failures.

Electrical Problems

If the dashboard controls don’t respond or the menu is missing, there could be a software glitch or electrical fault. A dealership or certified technician can run a diagnostic scan.

Leaks or Damage

If you find cracks in the reservoir or damaged hoses, it’s best to have them replaced by a professional to avoid further issues.

Under Warranty?

If your QX80 is still under warranty, contact an Infiniti service center. They can perform the reset and check for related issues at no cost.
