Toyota Prado 2016: How to fix problems?

Start with the owners manual and familiarise yourself with things like finding and using the jack, changing a tyre, checking the engine oil and coolant in the radiator. I wouldn’t worry too much about making temporary repairs on the trip; there are plenty of mechanics that can help you if you strike trouble. There will also be plenty of other tourists who would be only too happy to help a fellow traveller in trouble. Have your car checked before you leave, so everything is in fine working order when you hit the trail. Make a note of the Toyota dealers along your planned route, and if you are going to remote areas make a note of where you will be able to get fuel, and the mechanics along the way who might be able to help you in an emergency.
