Kia Check BRAKE SWITCH fuse in car: LCD message and EV start
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
The "Check BRAKE SWITCH fuse" message means the brake switch fuse is disconnected or blown. Replace the fuse with a new one before starting, or hold the EV button for 10 seconds in POWER ON and visit an authorised Kia workshop.
Safety first
Stop and check this first
- Never bypass the BRAKE SWITCH fuse or fit a fuse with a higher rating: if a new fuse does not clear the fault, have an authorised Kia workshop inspect the circuit.
- Starting the car by holding the EV button for 10 seconds is only an emergency measure when you cannot replace the fuse first; have the brake switch circuit checked promptly.
Safe checks you can perform

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Brake switch circuit and fuse box inspection
What they doThe authorised Kia dealer or service partner inspects the BRAKE SWITCH fuse terminal, the brake pedal switch and the wiring harness to find why the fuse disconnected or blew.
They must show youthe condition of the fuse and fuse holder, the live brake switch signal in the diagnostic tool and working brake lamps.
In writingthe root cause of the fuse failure, any replaced switch or fuse and confirmation that normal starting works.
Diagnostic scan if the LCD message stays on constantly
What they doIf the message remains displayed with an intact fuse, the workshop scans the body and start control modules and clears the stored fault after repair.
They must show youthe stored fault codes and the cluster with both the LCD warning and the Master warning light extinguished.
In writingthe fault codes read, the repair performed and the final start-up check result.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Read the exact LCD message alongside the Master warning light
- Who:
- you, with the vehicle parked when attempting to start.
- How:
- check the instrument cluster LCD display; Kia explains that the Master warning light illuminates whenever a malfunction occurs in various functions and points you to the LCD warning message for details.
- Result that matters:
- confirming that normal brake-pedal starting is blocked by the BRAKE SWITCH fuse alert.
- If "Check BRAKE SWITCH fuse" is displayed:
- follow Kia's steps to replace the fuse or use the 10-second EV button start.
- If "Press start button again" is displayed instead:
- press the EV button once more, and if it appears every time, visit an authorised Kia dealer.
- Evidence to keep:
- photo of the LCD display message and the Master warning light on the cluster.

Replace the BRAKE SWITCH fuse with a new one
- Who:
- you if you have a matching spare fuse, or a workshop if you prefer not to open the fuse box.
- How:
- with the vehicle switched off, inspect the BRAKE SWITCH fuse and replace it with a new fuse of the exact same rating before starting the vehicle, as instructed in the Kia manual.
- Result that matters:
- restoring the brake pedal switch signal required for normal starting.
- If the message clears with the new fuse:
- verify that the car starts normally when pressing the brake pedal and EV button.
- If the new fuse blows again or the warning stays on:
- do not fit a higher-rated fuse; book an inspection at an authorised Kia workshop.
- Evidence to keep:
- photo of the removed fuse and a note of whether the replacement held.
Low risk with the vehicle switched off. Never fit a fuse of a higher rating or touch any high-voltage wiring.

Start the vehicle by holding the EV button for 10 seconds
- Who:
- you, only if replacing the fuse first is not possible and you need to move the vehicle to a workshop.
- How:
- set the vehicle to the POWER ON or DRIVE READY position and press the EV button for 10 seconds, which Kia provides as a fallback when you cannot replace the fuse before starting.
- Result that matters:
- starting the vehicle temporarily so it can be taken for service.
- If the vehicle starts:
- check that the brake lights work properly before moving and drive carefully to an authorised Kia dealer or service partner.
- If the vehicle still will not start or you notice any braking abnormality:
- do not drive and arrange recovery.
- Evidence to keep:
- note of whether the 10-second EV button start worked and when the message first appeared.

What it means
In the Kia SV1 2025 owner's manual (UK English edition), "Check BRAKE SWITCH fuse" is shown on the instrument cluster LCD display, accompanied by the Master warning light, when the brake switch fuse is disconnected. Kia instructs you to replace the fuse with a new one before starting the vehicle, and provides an emergency start method by pressing the EV button for 10 seconds in the POWER ON or DRIVE READY position if replacement is not immediately possible. If the message stays on constantly with no operating problem, Kia recommends inspection by a professional workshop. The message alone does not prove whether only the fuse failed or the brake switch circuit has a deeper fault.
