Deactivating 2011 Grand Marquis daylight running lamps (DRL)
To activate daylight running lamps, owner's manual says: 1. the key must be in the ON position; 2. the headlamp control is in the OFF or Parking lamps position; and 3. the vehicle is not in Park.
It doesn't say how to deactivate them. Can someone tell me how to do this. Thanks.
