Step-by-Step Instructions

Follow these steps carefully

1

Check pressures cold, before driving

Tire pressure must be measured cold — first thing in the morning, or after the Jetta has sat for a few hours. Unscrew each valve cap and keep the four caps together in your pocket so none go missing.

2

Read your numbers off the door-jamb placard

Open the driver's door and find the Tire and Loading Information label on the B-pillar — the door jamb. It lists the correct cold inflation pressures for your Jetta's original tire sizes, front and rear separately. Use those numbers.

3

Inflate each tire to the placard value

Press your gauge squarely onto each valve stem and read the pressure. Recheck with the gauge after every adjustment — gas-station gauges and built-in inflator gauges are often optimistic.

🔧 Mechanic's note — Tom Becker

I press my own gauge squarely on the stem and recheck after adjusting — I've seen gas-station gauges read optimistic by 5 PSI, and that's the difference between even and uneven wear.

4

Reset the tire-pressure monitor

The 2015–2018 Jetta uses an indirect monitoring system: it watches wheel speeds through the ABS sensors rather than using pressure sensors inside the tires, so after any pressure change you must teach it the new baseline.

5

Drive so the system can relearn

After the reset, drive normally for 10 to 20 minutes. The system needs real rolling data to learn the new baseline wheel speeds, and the warning light should go out during this drive.

6

Understand what the light is telling you

A solid tire-pressure warning light means one or more tires is significantly under-inflated — check pressures again right away. Knowing the difference saves you from chasing pressures when the electronics are the problem.

7

Make it a monthly habit

Tires naturally lose a little air every month, and every 10-degree Fahrenheit drop in temperature costs roughly 1 psi — which is why the light loves to appear on the first cold morning of fall.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

  • • Inflating to the sidewall maximum instead of the door-jamb placard
  • • Resetting the monitor before setting the pressures — the system learns whatever is in the tires at reset time
  • • Checking pressure right after highway driving and under-inflating as a result
