Aoa.
First of all congratulations. Allah naseeb kary.
First and Most important suggestion. Dont let mechanics to touch your Car Unless its really required.
As you were asking mechanics in Islamabad, than consult Toyota Capital Motors.
You need to check condition of Engine oil, oil Filter, Air Filter and CVT Fluid.
My suggestions for engine oil are
Zic 0w30 or Liqui Moly 5w30.
If CVT Fluid is needed to be change, than use Toyota CVT Fluid, Tin pack.
The first and basic maintenance required is engine oil, filters, and breaks service.
That's all. Dont let mechanics to touch your Car's engine or any other electronic equipment.
Have a safe drive.
