Congratulations dear.
My advise which i give to all new swift owners based on my over 2 years of swift experience :):
1.Change the plugs to iridiums(NGK IFR6J11 or Denso IK20)use only these ones.
2.Use ZIC XQ 5W40 or any other good fully synyhetic oil.
3. Drive with care in running in period as per instructions in owner's manual.
4. Keep air pressure as recommended(33 front, 30 rear)
5.Keep on getting the AC air filter cleaned(located under front glove box) on every service and also keep the air filter clean.
Happy motoring.
