Hello,
Wanted to ask if there's any hidden features on the smart key like rolling down the windows, opening the trunk with just a simple touch, turning on the engine . Is there any of those features? If there is , please teach me , thank you !

 

You dealership should do it for free . It's already built in to is

 

I tried holding the unlock button to roll the window down but it doesn't work, so I have I go to the dealer to program it?

 

The dealer has to do that feature. There's another thread about features you can get done and that's one of the ones the dealer has to do.

 

Here's a list of programmable features:

also the dealer has to set the times you want the turn signal to flash on first position left or right

factory set up is three times, I will have mine change to 5 flashes.

options are 3,5,7

 

Thanks so much guys! I'll be heading to my dealer

 

You can actually change turn signal setting yourself. See the thread from the attached link.
