Hi All I bought a Lexus RX400h (2006) for my son. This car is supposed to have Daytime Running Lights (DRL). But the headlights don't turn on with low intensity when engine is turned on (when "READY" is displayed on the dashboard). I've read on the internet that this DRL is only enabled on certain Lexus models in certain countries where DRL is mandatory. Does anybody know whether 2006 RX400h sold in Australia had DRL enabled or not? If not, has anybody managed to turn it on?
