Well, I think you're right in your point about the extreme heat. It really needs attentionJean, you should probably begin by looking at the owners manual to see what the maintenance schedule recommends. It seems that your most likely problems, other then routine maintenance would come from the extreme heat in Dubai. When I was in Saudi Arabia the main things I checked most frequently were my air filter (because of dust storms), radiator fluid, and tire pressure. Other than those I don't think maintenance in Dubai would be any different than in any other country.
