Quick Answer

To reset the TPMS on your Hyundai H350, inflate all tires to the recommended pressure (typically 65 psi front, 80 psi rear when loaded), then drive above 25 mph for 10–20 minutes. The system automatically relearns and the warning light turns off. If it stays on, locate the TPMS reset button under the steering column or in the glove box, press and hold until the light blinks three times, then release.

Understanding TPMS in the Hyundai H350

The Hyundai H350 uses a direct TPMS system, meaning each wheel has a dedicated pressure sensor mounted inside the tire. These sensors transmit real-time pressure data to the vehicle’s ECU. Unlike indirect systems that rely on wheel speed sensors, direct TPMS gives you exact psi readouts for each tire.

Common Warning Light Triggers

Seasonal temperature drops – Cold weather reduces tire pressure by roughly 1–2 psi per 10°F drop, often triggering the light.
After tire rotation or replacement – Sensors may need to be re-registered to their new positions.
New sensor installation – Must be programed to the H350’s ECU.
Punctured or leaking tire – A slow leak can cause the light to come on intermittently.

Sensor Battery Life

The TPMS sensors in the H350 are powered by internal batteries that typically last 5 to 10 years. When the battery is low, the light may blink for 60–90 seconds at startup, then stay solid. If you see this pattern, sensor replacement is likely needed.

Step-by-Step Reset Procedure

Method 1: Automatic Relearn (Most Common)

Check and adjust tire pressures to the values printed on the driver’s door jamb sticker. For the H350, front tires usually need 65 psi and rears 80 psi when fully loaded. Use a reliable digital gauge.
Drive the vehicle at a steady speed above 25 mph (40 km/h) for 10–20 minutes. The sensors will transmit updated readings, and the ECU will automatically relearn the correct pressure.
Verify – The TPMS light should turn off after a few minutes of driving. If it doesn’t, move to the next method.

Method 2: Manual Reset Button

Locate the TPMS reset button – On the H350, this button is typically found under the steering column, inside the glove box, or behind the fuse box cover. Look for a small button labeled “TPMS,” “SET,” or with a tire icon.
Turn the ignition to the ON position (engine off). Do not start the engine.
Press and hold the reset button for 3–5 seconds until the TPMS light blinks three times.
Release the button, start the engine, and drive for a few minutes. The light should remain off if pressures are correct.

Tip: If you can’t find the button, check the owner’s manual. Some H350 fleet models omit the button entirely.

Method 3: Infotainment System (2018+ Models)

Newer H350 models (2018 and later) allow you to reset the TPMS through the touchscreen:

Press the Setup button on the infotainment system.
Navigate to Vehicle Settings → Tire Pressure.
Select Reset or Relearn TPMS.
Confirm the action. The system will indicate when the reset is complete.

This method is especially convenient if you’ve just finished inflating the tires and are still parked.

Method 4: OBD-II Tool or Professional Scan Tool

When the manual methods fail—for example, after replacing sensors or if the button is missing—use a TPMS diagnostic tool. These tools plug into the vehicle’s OBD-II port and can trigger a relearn remotely. Many tire shops have these tools and can perform the procedure in minutes.

Troubleshooting: When the Reset Doesn’t Work

TPMS Light Stays On After Reset

If you’ve followed the steps above but the light remains on, check these possibilities:

Incorrect tire pressure – Double-check with a quality gauge. Don’t forget the spare tire if it has a sensor (common on full-size spares).
Faulty sensor – A sensor may be dead or damaged. Watch for a blinking light followed by a steady light—this is the classic sign of a sensor fault.
Sensor not recognized – After tire rotation, the vehicle may need a sensor ID relearn using a TPMS tool. The H350’s ECU stores the IDs of each sensor in a specific position (front-left, front-right, rear-left, rear-right). When you rotate tires, those positions change.
Battery drained – In cold climates, sensor batteries discharge faster. Extreme cold combined with an older sensor can trigger the light even if pressures are okay.

TPMS Light Blinks Then Stays On

A blinking light at startup (60–90 seconds) that then stays solid indicates a system fault. Common causes on the H350:

Sensor ID not programed to the ECU
Corrosion on sensor mounting bands (especially with steel wheels, which are common on the H350)
Aftermarket wheels installed without TPMS sensors

What to do: Use a TPMS diagnostic tool to read the sensor IDs from each wheel. If a sensor is missing or unreadable, replace it.

What to Do If the Button is Missing

Some H350 models, particularly fleet or cargo versions, do not include a physical TPMS reset button. In this case:

Use Method 1 (drive cycle) – it works if all sensors are functioning.
Use Method 4 (OBD-II tool) – a professional scan tool can force the relearn.

Tire Rotation and TPMS

Rotating tires on the H350 can confuse the TPMS because the sensors move to different positions. Without a reset, the light may come on even if pressures are correct. The solution: perform a sensor ID relearn using a TPMS tool that can map each sensor to its new location. Many tire shops include this service with rotation.

Comprehensive FAQ

How long does it take for the TPMS light to go off after reset?

Usually within 10–20 minutes of driving above 25 mph. In rare cases, it may take up to two drive cycles (starting and stopping the engine). If it stays on longer, recheck pressures or try the manual reset button.

Can I reset TPMS without a button or tool?

Yes. Inflate all tires correctly and drive above 25 mph for 20 minutes. The system will automatically relearn if all sensor signals are strong. This works for most pressure-related alerts.

Why does my TPMS light come on in cold weather even after reset?

Cold temperatures drop tire pressure by 1–2 psi per 10°F drop. Even if you reset it, the light may return when temperatures fall further. Add air to compensate—every 10°F drop requires roughly an extra 1 psi.

Does the spare tire affect TPMS on the H350?

Only if the spare is equipped with a sensor. Full-size spares on the H350 often have sensors. When the spare is used, its sensor must be programed to the vehicle. Check and adjust its pressure during regular maintenance.

How do I know if a TPMS sensor is failing?

The TPMS light blinks for 60–90 seconds when starting the engine, then stays on solid. This pattern indicates a sensor fault, dead battery, or missing sensor. Use a TPMS tool to identify which sensor is failing.

Can aftermarket wheels cause TPMS issues?

Yes, if they lack sensors or use incompatible sensors. The H350 requires 433 MHz sensors. Installing 315 MHz sensors or none at all will cause the light to stay on. When buying aftermarket wheels, ensure they accept the original sensors or purchase compatible replacements.

Will disconnecting the battery reset TPMS?

No. Disconnecting the battery may clear temporary error codes, but the TPMS light will return once the ECU detects the underlying issue (low pressure, missing sensor, etc.) again. Battery disconnect is not a usable reset method.

What is the correct tire pressure for the Hyundai H350?

Check the sticker on the driver’s door jamb. Typical values:

Front: 65 psi (4.5 bar)
Rear (loaded): 80 psi (5.5 bar) Adjust for load—if the van is empty, you can reduce rear pressure slightly, but never below the minimum listed.

How much does a TPMS sensor replacement cost for an H350?

Aftermarket sensors: $30–$60 each plus installation. Dealer replacement: $80–$150 each plus labor. The H350 uses a band-type sensor on steel wheels and a valve-stem type on alloy wheels—confirm which you need before ordering.

Is it safe to drive with the TPMS light on?

Yes, but check tire pressures immediately. Low pressure increases the risk of a blowout, reduces fuel economy, and causes uneven tire wear. If the light is blinking (system fault), driving is still safe, but have the system diagnosed soon.

Actionable Checklist

Verify tire pressure with a digital gauge (don’t guess)
Check the driver’s door jamb for correct psi values
Complete a 20-minute drive above 25 mph to trigger automatic relearn
Locate and use the reset button (if available) – hold 3–5 seconds
Test with a TPMS tool if the light persists after the above steps

Summary

Resetting the TPMS on your Hyundai H350 is straightforward in most cases: adjust pressures and drive. For stubborn lights, use the manual button or infotainment method (2018+ models). If the light blinks or stays on, suspect a sensor fault and consider professional diagnosis. Regular pressure checks every few weeks prevent TPMS alerts and extend tire life.
