Disabling the Daylight Running Lights in a 2005 XC90

[cec]

Does anyone know how to disable the DRLs in a 2005 XC90 V8 with HID headlights. The dealer tried and was able to disable the rear DRLs but not the front DRLs. Dealer said that up to 2004 models DRLs could be disabled but after 2005 this is no longer possible.

I have been told by Volvo service personnel that the DRL's cannot be disabled BUT you can control which lights come on ( I had a 2004 XC90 with BiXenon Headlamps). You can do that with the headlight selector switch. If the switch is placed in the upward ( on ) position, the BiXenons will come on during all driving conditions. If the headlight selector switch is placed in the full left ( off/automatic ) position, the DRL's will come on but it willa be the halogen lamps that illuminate during daytime running rather than the BiXenons. When the ambient light is below the threshold, the BiXenons will come on with the switch left in this position. However, you cannot engage the Hi Beam position on the BiXenons with that setting of the switch. If the headlight selector switch is turned to the up ( on ) position, then the BiXenons will be on and the Hi Beam selection can be made. The trick is to remember that when driving during daylight hours, the headlight selector switch should be in the full left ( off/automatic ) position and in the up ( on ) position during nighttime driving. I hope this helps

On '04 V70's you can have the DRL's illuminated. It does require a software download. Ask your dealer and see what they say.
