Congratulations on your new car 
.. Allah hifazat se rakhay aur acha naseeb karay
I really hope you bought car with verified auction sheet. What is the total milage uptil now ?
brother kamran zafar has answered all your questions perfectly.
I will just add a few points :
Changing of CVT, spark plugs etc depends on the total mileage , CVT is changed after atleast 40-50K. So mechanic ki baaton main aa ke CVT jaldi change na karana, (unless there is a real problem like the level of oil is lower than required)
Try using a mix of HOBC and Super petrol . maybee 50:50 or go all HOBC
for max mileage, drive with light foot .. meaning accelerate gradually instead of flooring the paddle. The car meter guides you when you are pushing more than required RPMs , it turns blue/violet . Keep it in green.
for tyre air pressure, for 155/65R114 the reccommended is 40psi , and for 165/55R15 recommended is 34psi.
mine is the first one, but I keep it aroundd 36-37 psi . good tyre pressure plays a lot of role in good fuel average.
I would strongly recommend you buy a spare tyre for driving on long route where puncture shop would not be available easily.
the standard according to manual is T115/70D14 . try to find the original japanese which is yellow rim colored. its very thin compared to normal. and recommended air pressure for this tyre is around 50psi . yes that feels too much but it is not. I filled mine with 46psi tho. I only keep it in the trunk for long route , out of city trips. for daily normal commute the emergency tyre puncture kit is enough.
in lahore, there is a shop "filter house" which has imported oil/air filters both malaysian and japanese. they are a bit costly but worth it. Don't know where you can get similar in rwp/isl tho. but do try to find and ask around may be you might find it. as last resort use guard filters (dont use lippon, or any other local)
liquiMoli 5w30 is also available in 4 Ltr package. may be the dealer in rwp/isl doesn't have it. the oil is a bit expensive compared to others but it also runs for more . it can go to atleast 7000+ Km , others need changing after just 4-4.5K .
rest kamran zafar covered almost everything
enjoy your ride
P.S:
before lahore's scorching summers, without AC my car was giving me 21+ km/ltr fuel avg . now in summers with AC its still giving me around 19 Km/Ltr Alhamdulillah (for AC , i turn the eco idle off bcz on stop it shutsdown the AC condenser , and so frequent on/off of condenser in my opinion is not good for its life)
