ZiC needs to be changed after 5-6000 km ,
I use LiquiMoli (german) according to company goes up to 8000 km , but i changed after 7000km .
At 43k you should not need to change CVT yet , but check the level and also the condition from a mechanic if its burnt out , then it will need changing but that is very rare that it gets bad before 70-80k km
Oil filter needs changing on every oil change , buy good one malaysian made . not local guard or any other.
Never ever put water in radiator "ever" , always use coolant , Use a good branded coolant like caltex etc . trust me its worth the money. it doesn't need changing for a very long time. The coolants 90% of the time come pre-mixed with water .. its written on it. no need to mix water yourself.
auto idle feature requires driver seat belt is buckled .. and also the batteries are sufficiently charged and powerful.
