How to Put a Kia EV6 into EPB Service Mode

Quick Answer: How to Enter EPB Service Mode in a Kia EV6

To put the Kia EV6 into EPB Service Mode (required for rear brake pad replacement), turn the vehicle ON (READY mode). Navigate to Setup → Vehicle Settings → Convenience on the infotainment screen, then toggle “Auto Hold” OFF. Next, press and hold the “EPB” switch (pull up) until you hear a mechanical sound and the “AUTO HOLD” and “EPB” warning lights turn yellow on the instrument cluster. The rear calipers will retract, allowing brake service. To exit, push and hold the EPB switch down (release) until the lights turn green.

Understanding the Kia EV6 EPB System

What is EPB (Electronic Parking Brake)?

The Electronic Parking Brake (EPB) replaces the traditional handbrake lever with an electric motor mounted directly on the rear brake caliper. When you pull the EPB switch, the motor pushes the piston against the brake pads, clamping the rotor. Release the switch, and the motor retracts. The Kia EV6, like its platform siblings (Hyundai IONIQ 5 and Genesis GV60), uses this fully electric system — there is no mechanical cable or manual lever.

Why a Specific “Service Mode” is Required

Here’s the critical point: you cannot simply push the caliper piston back with a C-clamp or a wind-back tool. The EPB motor and the threaded piston assembly are not designed to be forced. Doing so can strip the internal gears, burn out the motor, or damage the caliper seals. The car’s ECU must command the motor to retract the piston electronically — that’s what Service Mode does.

Common Scenarios Requiring Service Mode

You’ll need to activate EPB Service Mode whenever you work on the rear brakes:

  • Replacing rear brake pads or rotors – The pads won’t slide out unless the piston retracts fully.
  • Performing a brake fluid flush – With the piston pushed back, old fluid can flow out of the caliper bleeder more easily.
  • Replacing the rear brake caliper assembly – The caliper must be in the fully retracted position before removal.

Step-by-Step Procedure to Activate EPB Service Mode

Prerequisites

Before you begin, make sure:

  • The vehicle is parked on a level surface.
  • The rear wheels are chocked (front and back) to prevent rolling.
  • The ignition is in “ON” mode — the READY indicator must be on. For an EV, this means pressing the Start button without your foot on the brake (or with foot on brake if you need to shift). The instrument cluster should show “READY.”
  • The transmission is in P (Park) .
  • All doors are closed.
  • Your foot is off the brake pedal — the procedure may not initiate if the brake is applied.

Step 1: Prepare the Infotainment System

  1. Press the “Setup” button on the dashboard (the gear icon on the touchscreen).
  2. Select “Vehicle Settings” from the menu.
  3. Navigate to “Convenience” (or “Driver Convenience” on some software versions).
  4. Locate the “Auto Hold” toggle — make sure it is turned OFF (slider to the left). If Auto Hold is on, the system will not enter Service Mode.

Note: On 2024 and later models with updated software, the Auto Hold toggle may be under Setup → Vehicle → Driver Convenience or Vehicle → Settings → Auto Hold. The name changes slightly, but the function is identical.

Step 2: Activate the Service Mode via the EPB Switch

  1. Find the EPB switch on the center console — it’s the small button labeled “P” with a brake icon, located just behind the gear selector.
  2. Pull the EPB switch UP (the same motion you use to engage the parking brake).
  3. Hold the switch in the UP position for 3–5 seconds. Don’t release it early.
  4. Watch for Confirmation:
    • You will hear a loud mechanical whirring or clunking sound from the rear of the vehicle — that’s the electric motor retracting the piston.
    • The “EPB” and “AUTO HOLD” warning lights on the instrument cluster will change from green to yellow/amber .
    • A message reading “EPB Service Mode” may appear briefly on the cluster or infotainment screen.

Step 3: Confirm Retraction

  • Walk to the rear of the vehicle and visually inspect the calipers.
  • The piston should be fully retracted into the caliper housing — you’ll see a gap between the piston face and the inner brake pad.
  • The brake pads will be loose and easily removable. You can slide them out by hand without excessive force.

If the piston is still protruding or the pads feel stuck, do not force them. Repeat the procedure from step 1, making sure Auto Hold is truly off.

Troubleshooting Common Activation Issues

Issue Cause Solution
Yellow light won’t appear Auto Hold is still ON. Re-check the infotainment Setup menu; ensure the Auto Hold slider is OFF.
No mechanical sound Transmission not in Park, or door is open. Shift to P, close all doors, keep foot off brake, and restart.
Lights flash but no retraction Low 12V battery voltage. Connect a trickle charger or jump starter to the 12V auxiliary battery. The EPB motor needs adequate voltage.
Message “Conditions Not Met” Brake pedal applied, or a door is open. Release the brake pedal and close all doors. Some models also require the driver’s seatbelt to be unbuckled.
Procedure works but won’t exit Caliper may be mechanically stuck. Gently tap the caliper with a rubber mallet while holding the EPB switch down. If still stuck, consult a service manual.

Deactivating EPB Service Mode (How to Return to Normal)

Once you’ve finished the brake work, you must exit Service Mode before driving. Driving with the EPB in Service Mode means the parking brake will not engage — a serious safety hazard.

  1. Ensure all brake work is complete and the rear wheels are installed and torqued to specification.
  2. Turn the vehicle ON (READY mode).
  3. Push the EPB switch DOWN (the same motion used to release the parking brake).
  4. Hold it down for 3–5 seconds.
  5. Confirmation:
    • You’ll hear the motor cycle again — the calipers will motor back into position, pushing the piston against the pads.
    • The warning lights on the instrument cluster will turn back to green.
    • The message “EPB Service Mode Off” may appear.
  6. Test the parking brake: pull the EPB switch up briefly — it should engage and hold the vehicle.

Important: If you turn off the vehicle without exiting Service Mode, the system may fault on the next startup. In that case, re-enter and properly exit Service Mode to clear the warning.

Why You Should NOT Use a Wind-Back Tool

Traditional brake calipers have threaded pistons that require a wind-back tool to retract. The Kia EV6’s rear calipers use an electronic actuator — a small motor that turns a screw mechanism. The piston has no cross-drilled slots for a wind-back tool. Attempting to force it will shear the plastic gear or strip the threads, requiring a full caliper replacement.

12V Battery Voltage

The EPB system runs off the small 12V auxiliary battery, not the high-voltage traction battery. A low 12V battery is the number one cause of Service Mode failure. If you get no response from the EPB switch, test the 12V battery voltage first — it should be at least 12.4V. If it’s below 12.0V, charge it or jump-start the 12V system before proceeding. For more details on maintaining the EV6’s 12V system, check out our guide on Kia EV6 battery maintenance.

Comparison to Hyundai IONIQ 5 / Genesis GV60

The Kia EV6 shares the E-GMP platform with the Hyundai IONIQ 5 and Genesis GV60. The procedure for entering EPB Service Mode is nearly identical on all three vehicles. The only difference is the infotainment menu path:

  • Kia EV6: Setup → Vehicle Settings → Convenience → Auto Hold OFF
  • Hyundai IONIQ 5: Setup → Vehicle → Convenience → Auto Hold OFF
  • Genesis GV60: Setup → Vehicle → Settings → Auto Hold OFF

The EPB switch location and the hold-up activation method are the same across the board. If you’re working on multiple E-GMP vehicles, the same steps apply.

Frequently Asked Questions (FAQ)

Do I need a special diagnostic tool (GDS) to do this?

No. Unlike some older Kia models (like the Stinger or certain Hyundai Genesis sedans), the EV6 allows Service Mode activation directly from the infotainment menu and EPB switch. A GDS (Generic Diagnostic System) is only needed if you’re replacing an EPB actuator or diagnosing a fault code — not for routine brake service.

Can I do this without the infotainment screen?

No. You must manually disable Auto Hold in the vehicle settings. If you skip this step, the system will ignore the EPB switch command. There is no workaround — you need the touchscreen functional.

How long does service mode stay active?

It stays active until you manually exit it by pushing the EPB switch down. However, if the 12V battery dies or the vehicle is turned off while in Service Mode, the system may fault. Always exit Service Mode before turning off the car. If the battery dies mid-service, you’ll need to jumpstart the 12V system and repeat the exit procedure.

Why are my rear brakes dragging after service?

This usually means you did not exit Service Mode properly. The calipers are still retracted, allowing the pads to float — but when you drive, the pads can shift and contact the rotor unevenly. Re-enter Service Mode and then properly exit it. Also check that the caliper slide pins are lubricated and not seized.

Is it safe to drive in service mode?

No. Service Mode disables the electronic parking brake. While the service brakes (hydraulic system) will still work normally, the parking brake will not hold the car when parked. Never drive with the EPB in Service Mode.

My 2024 EV6 doesn’t have the same menu. What changed?

Recent over-the-air (OTA) software updates may relocate the Auto Hold toggle. Look under Setup → Vehicle → Driver Convenience or Vehicle → Settings → Auto Hold. The toggle may be labeled “Auto Hold” or “Automatic Hold.” The underlying procedure — holding the EPB switch — remains the same. If you can’t find the setting, consult your owner’s manual or Kia’s official support site.
