But since your car is new, you may not need to check all of the above but no harm in doing all the checking though...
you might also want to check for hotline of your insurance, or towing service provided by your insurer or dealer.
And also you may want to check the weather(not necessarily from our very reliable PAGASA ), your possible pitstops (rest points).
