2022 Hyundai Ioniq 5 EV Service — 12V Battery & Cabin Air Filter DIY Guide

The 2022 Hyundai Ioniq 5 has no engine oil to change — but it still needs regular maintenance that most EV owners overlook. The two most common DIY services are the 12V auxiliary battery replacement (typically needed every 3–5 years) and the cabin air filter swap (annual or 15,000 miles). Dealers charge $150–$250 for the 12V battery service alone. Both jobs are under 30 minutes combined.

Part 1: 12V Auxiliary Battery Replacement

Step 1: Power Down the Ioniq 5

Ensure the Ioniq 5 is completely powered off — not in "Ready" mode. Open the hood. The 12V auxiliary battery is located on the right side of the frunk area (passenger side), covered by a black plastic trim panel.

Step 2: Remove the Battery Cover

The battery cover is secured by two 10mm bolts. Remove them and lift the cover off.

Step 3: Disconnect the Negative Terminal First

Loosen the 10mm clamp bolt on the negative (-) terminal. Slide or twist the terminal off the post. Secure it away from the battery.

Step 4: Disconnect the Positive Terminal

Remove the plastic cover from the positive (+) terminal. Loosen the 10mm clamp bolt and remove the terminal.

Step 5: Remove the Battery Hold-Down

Remove the single 10mm bolt at the base of the hold-down bracket. Lift the bracket away.

Step 6: Remove the Old Battery

Lift the old battery straight out. H6 batteries weigh 40–50 lbs — use both hands.

Step 7: Install the New AGM Battery

Set the new AGM battery into the tray in the same orientation. Reinstall the hold-down bracket and tighten the 10mm bolt snugly (approximately 8–10 lb-ft).

Step 8: Reconnect Terminals

Connect positive first, then negative. Tighten the 10mm clamp bolts. Replace the positive terminal cover. Reinstall the battery cover.

Step 9: Power On and Verify

Press the start button. The Ioniq 5 should power on normally. Follow any prompts for driver preferences or window calibration.

Part 2: Cabin Air Filter Replacement

Step 1: Locate the Filter Housing

The cabin air filter is behind the glove box. Open the glove box fully and squeeze the side tabs inward — this allows the door to drop below its normal stop, exposing the filter housing.

Step 2: Remove the Filter Door

Slide the housing door to the right and pull it off. No tools required.

Step 3: Slide Out the Old Filter

Pull the Hyundai 97133-GI000 filter element straight out. Note the airflow direction arrow on the side of the old filter.

Step 4: Install the New Filter

Slide the new 97133-GI000 filter in the same orientation, with the airflow arrow pointing toward the blower.

Step 5: Reinstall the Housing Door

Slide the door back on. Push the glove box back up into its locked position.
