It's probably not DRLs, but a headlight off delay feature.
If you turn of the ignition before the headlights, the headlights only are designed to stay on for up to a couple minutes. This was included on many of the upper trim level vehicles.
If you turn the headlights off before the ignition, the delay is bypassed. Likewise if you turn the headlights off then on again the delay is cancelled.
