There are several ways to rest this light that all involve some level of dismantling your dashboard, the differences are based on the equipment package and the year of the vehicle. I'm hesitant to answer in detail because based on your vehicle specifics I may give you the info for the wrong model, so here is a quick answer;
One method involves moving the "timing belt screw" behind the instrument cluster from one position to another (it is marked and will be obvious when you see it) Another involve pushing a pin through a rubber grommet on the instrument cluster to reach a reset button, while another still is an electronic reset you can do with the trip meter reset on your instrument cluster. The steps to remove the dashboard, if necessary for your car vary by model since the cluster will be different. Do a Google search for Toyota hiace forum, then search timing belt reset. The good news,the Toyota hiace owners forum covers this in detail, with pictures and a detailed discussion that i could not fit here. When you find the information pertaining to your specific model, please share with others.
Good luck

Yes, there is an ABS light indicator in the 2004 Toyota Highlander model.
no the 4-cylinder model has a timing chain
A little more information please ( what year , what model of Toyota , what is the engine size )
As the owner of Toyota hiace standard cabin passenger van 2011 I found hiace is very powerful and fast acceleration then Mitsubishi L200 4by2 2012 but I don't know about Nissan because Nissan sunny has slow acceleration but Nissan pathfinder has fast. personally I prefer Toyota corolla then Nissan sunny but I prefer Nissan Altima then Toyota camry and I prefer Nissan pathfinder to Toyota prado and I prefer Nissan patrol then Toyota land cruiser but Nissan caravan which is also known as urvan in some countries the previous model was not better design then Toyota hiace but the new model I think its 2013 and 2014 is better look then hiace.i never drive caravan but you have to know a litter dirty secret of Toyota hiace its suck in cross wind even during the overtaking a bigger truck is also found difficult because of wind, body shape and light weight. about the top speed I reached 160km very easily but its handling suck also your will b feel huge impact on the humps because shock absorber are not fine specially when you the vehicle is not full loaded just check with some one about caravan,urvan because I never tested this vehicle I hear in some countries the maximum speed limit for hiace is drop from 120km/ph to 90km/ph for safety concern about its design.
