Just got my 4x2 santa fe last week and oh boy its a joy to drive

have a couple of questions lang po on the features:
1. Are the led lights in the headlight parklights or DRLs? Cant seem to have them function as DRLs.
2. When you set the a/c to auto climate control, how do you configure it so that the recirculate air button doesnt turn off by itself?
3. Is the side mirror autoswivel feature during reverse available sa 4x2 local unit? Tried it kasi and it doesnt function as described.
Thanks po in advance.
