| Hood and liftgate closed | The vehicle does not remotely start if the hood or liftgate is open. |
| Smart key within 32 ft. (10 m) | The Remote Start button may not operate if the key is farther away. |
| Remote Start pressed within 4 seconds of locking | The manual's steps require pressing Remote Start within 4 seconds of the door lock button. |

From the smart key, Driving Your Vehicle and software update sections of the 2027 Tucson owner's manual, read October 26, 2026.
After the engine starts
The 2027 Tucson manual says the engine turns off if you do not get in within 10 minutes after remotely starting the vehicle.
When you do get in, carry a registered smart key. If you get in without one, the engine turns off and the vehicle displays "Smart Key must be present to keep the vehicle running".
Using a phone digital key
| Phone | Per the 2027 Tucson manual |
|---|---|
| Ultra Wide Band phone | When the phone and vehicle are connected by Bluetooth, Remote Start, Door Lock/Unlock and Panic are available in the app provided by the phone maker. To start remotely, lock the vehicle with the door lock button in that app and press the remote start button within 4 seconds; the vehicle starts and the hazard warning lights blink. Press remote start again to turn it off. |
| Phone without UWB | Place the registered phone on the vehicle authentication pad (wireless charging pad), press the brake pedal and press the Engine Start/Stop button. The manual describes no remote start for these phones. |
The manual says this app function is only for Ultra Wide Band phone digital keys, the phone's Bluetooth must be on, and the Bluetooth range can vary with the surroundings.

Remote start through Bluelink
According to the 2027 Tucson manual, the vehicle can also be remotely started through the Bluelink subscription; it refers you to the Bluelink manual. Read more on our Blue Link page.
Vehicle auto-shut off (if equipped)
Separate from the 10-minute remote start limit, the 2027 Tucson manual describes a vehicle auto-shut off that turns the engine off if the vehicle is parked and left running for a long time, to help reduce fuel consumption and help prevent accidents.
The timer runs only when all of the manual's conditions are met, among them speed below 1.8 mph (3 km/h) in P (Park), neither pedal pressed, the driver's seat belt unfastened and the passenger seat empty. When it runs, the engine turns off after 60 minutes, and a timer appears on the cluster display 30 minutes before.
