OEM DRLs only work when headlights are off (parking lights can be on), engine running, transmission in drive, perhaps reverse.

HIDs (Bi-xenon headlamps) were not available from the factory on the 2013 Laredo. HID DRLs are a separate bulb closest to the grill. DRLs were a Lareado option in the US market and only available in the All-Weather package I think, which also included the two speed transfer case. Depending on the market, the optional Laredo DRLs shared the high or low beam bulbs and were driven at a lower voltage.

There may be DRL relays in the power distribution center that affect its operation. If the relays are pulled, DRLs may be disabled.

Many have had their dealer activate the DRLs and its just a matter of checking the activate DRL box. You can also change it to Canada mode, but that has some other side effects.

If you have aftermarket or hacked headlights, dunno. I think there is a link in the FAQ sticky thread on how to get a build sheet and find out what was installed at the factory.

Doesn't make sense, may have been modified/hacked. OEM HIDs only use the inner lights for DRLs. Both high and low beams are controlled by the shutter and illuminated by the outer bulb. HIDs will also have a leveling motor and ballasts.
