This procedure relearns the Tire Pressure Monitoring System (TPMS) sensors after tire rotation, replacement, or pressure adjustment on the 2016-2024 Hyundai Tucson with 2.5L I4 AWD engine.

Warnings

Tools required

Preparation

1. Park vehicle on level ground and engage parking brake
2. Locate the tire pressure specification label on the driver's door jamb
3. Ensure the ignition has been OFF for at least 2 minutes before starting
4. Have the vehicle identification number (VIN) available if using a TPMS tool

Procedure

1. 1

   Verify and adjust tire pressures
   Using a quality tire pressure gauge, check the pressure in all four tires. Inflate or deflate each tire to match the specification on the driver's door jamb label (typically 35 PSI front and rear for this model). Ensure all tires are at the exact same pressure if the specification is uniform, or match front/rear specifications as labeled.
2. 2

   Check spare tire pressure (if equipped with TPMS spare)
   Some Tucson models monitor the spare tire pressure. If your vehicle is equipped with a full-size spare that has a TPMS sensor, verify and adjust the spare tire pressure to the specification on the door jamb label (typically 60 PSI for compact spare or same as other tires for full-size spare).
3. 3

   Turn ignition to ON position
   Insert the key and turn the ignition to the ON position without starting the engine (or press the start button twice without pressing the brake pedal for push-button start models). Verify that the TPMS warning light illuminates on the instrument cluster during the bulb check, then wait for it to turn off after a few seconds.
4. 4

   Drive vehicle to initiate auto-relearn
   Drive the vehicle at speeds above 20 mph for at least 10-15 minutes. The Tucson's TPMS system will automatically detect and relearn sensor positions during normal driving. Vary speeds between 20-60 mph and include some turns to help the system identify individual wheel positions.
5. 5

   Monitor TPMS warning light
   After driving, park the vehicle and turn the ignition OFF, then back ON. The TPMS warning light should remain off if the relearn was successful. If the light remains illuminated or flashes, proceed to the manual reset method in the next step.
6. 6

   Perform manual reset if needed
   If the TPMS light remains on after the drive cycle, turn the ignition to ON (engine off). Navigate to the User Settings menu on the instrument cluster using the steering wheel controls. Select 'Convenience', then 'Tire Pressure', then 'Reset'. Confirm the reset when prompted. This will clear stored pressure values and force a new baseline.
7. 7

   Complete final drive cycle
   After manual reset, drive the vehicle again for 10-15 minutes above 20 mph to allow the system to relearn all sensor positions and establish new baseline pressures. The TPMS system needs to receive signals from all sensors during active driving to complete the process.

Reassembly

1. No reassembly required for this procedure

Verification

• Turn ignition to ON position and verify the TPMS warning light illuminates briefly during bulb check, then turns off within 3-5 seconds
• Use the instrument cluster display to view individual tire pressures (if equipped with display feature) and confirm all four tires show correct readings
• Drive the vehicle and monitor that the TPMS light does not illuminate during normal operation
• If the light flashes for 60-90 seconds then stays solid, one or more sensors may be faulty or missing and require diagnosis with a TPMS scan tool
• Recheck tire pressures after 24 hours to ensure no slow leaks are present
