1) Per-jo (with a soft "j" as in the word "je" in French)
Sit-ruhn or Sit-r'n
Jaguar is pronounced in the same way as the animal: Jag-you-er
Hyundai is pronounced by most people as: Hi-yuhn-die but some people use closer to the Japanese pronunciation of "Hyuhn-die". The difference is in the number of syllables. Those who use the first pronunciation give it three syllables, the second pronunciation has two syllables.
I don't do phonetic symbols. Someone will probably be able to put the pronunciations into symbols for you.
