1. That plastic tag that came with my key actually has a unique code. I need to provide it to Hyundai if I need to order another key. The manual recommends not lose it.
  2. My warranty isn't really for 5 years. It's for 3 years + 2 from an insurance company. Couldn't find any info about this extended insurance policy.
  3. The suggested maintenance interval is not what is recommended in the car's manual.
  4. HARI has no written rule/statement about extending the 3 month interval. Be careful when your dealer says they are not very "strict" about this. Suggest you ask them to note or stamp on your service passport that you are still within warranty after every maintenance work.
