Starting up/shutting off vehicle

Hi, I have owned my Tucson '22 SEL for 3 weeks and sat in it nightly with the manuals to learn it however I am still confused about how to turn engine on & off. Foot always on break pedal or not? Push button once or twice, three times? Sometimes the break pedal feels really stiff & I have to press hard, other times it feels looser. I have started it both ways and I see it goes through an accessory mode with one press of the button but also sometimes that one press starts it.

You need to put pressure on the brake pedal and hold the pressure, while you press the button once. So to start the car hold the brake pedal down, push the start/stop button. To turn off the car, hold pressure on the brake pedal, make sure the car is in PARK, then push the start/stop button. If that does not work, then you have an issue with the car. I admit, I got confused by this when I first got the car. Forget the manual for now search for the U-Tube Video's, there are dealerships who made some really good video's search google for "2022 Tucson SEL video"

Based on my own experience and experimentation...
  • WITH THE VEHICLE / ENGINE OFF
    • No Brake
      • Push Button once to enter accessory mode
      • Push Button a second time to turn the vehicle "on", without actually starting the engine
      • Push button a third time to turn the vehicle off
    • While Holding Brake
      • Push button to start the engine

  • WITH THE VEHICLE / ENGINE RUNNING
    • Push the button to turn the vehicle off (no brake needed)

One extra point. After you put it in park, keep slight pressure on the brake before applying the parking brake, as it says in the manual and online instruction video. It saves wear and tear on the parking brake actuators.
With the push button transmission, turning off the car (non-hybrid) while in gear appears to automatically switch to Park. I didn’t find anything in the manual to indicate if it’s acceptable to do this as standard procedure.

Yes, you can do this, but if you’ve configured the “auto-unlock in P” feature, it won’t work … all doors remain locked.

If I forget to turn off the car and walk away, will the car eventually turn itself off?
As far as the different stiffness feel of the brake pedal, that might have to do with how recently the car was driven. If the Hyundai power brake assist works the same as it has in cars for decades, it provides braking assist with engine vacuum. On an old SUV I owned years ago, there was a check valve on the vacuum hose between the intake manifold and the brake master cylinder that would hold vacuum in the cylinder for a while, but eventually (maybe a day) the vacuum would bleed down. So, if you started the car after sitting for a matter of hours, there would still be residual vacuum in the master cylinder that would let the brake pedal depress easier. If the car sat for a day or more, that vacuum would be gone and the pedal would feel stiffer.
