Estimated Time

30 minutes - 1 hour

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked on a stable surface when checking tire pressures.
•Avoid over-inflating tires; always adhere to the manufacturer's recommended pressure.

Symptoms

•Low tire pressure warning light on the dashboard
•Visual alert on the center display for specific tire(s)
•Decreased handling performance
•Increased tire wear
•Possible decrease in driving range

Diagnostic Steps

1
Check the tire pressure of all four tires using a tire pressure gauge.
2
Inspect tires visually for any visible signs of damage, punctures, or foreign objects.
3
Verify that the tire pressure monitoring system (TPMS) is functioning by observing if it resets after adjusting tire pressures.
4
Check the manufacturer’s recommended tire pressure, typically found on a sticker inside the driver’s door jamb.
5
Inspect for any leaks around the valve stems or bead areas of the tires.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, valve stem cap tool (if needed).
Park the vehicle on a level surface and ensure the tires are cool to the touch for an accurate reading.
Disconnect the vehicle from charging if applicable.

2. Check and Adjust Tire Pressures

Sub-step 1: Use the tire pressure gauge to measure the current tire pressure of each tire.
Sub-step 2: Compare the measured pressures against the manufacturer’s recommended PSI (pounds per square inch).
Sub-step 3: If any tire is below the recommended level, use an air compressor to inflate the tire to the correct pressure.
Sub-step 4: Recheck the tire pressure after inflation to ensure it is at the correct level.
Sub-step 5: Replace valve stem caps securely after checking or inflating.

3. Reset TPMS (if necessary)

Sub-step 1: Turn on the Model Y and navigate to the ‘Service’ menu on the center display.
Sub-step 2: Select the "Tire Pressure Monitoring System" option and choose "Reset."
Sub-step 3: Follow any additional prompts to confirm the reset.
