You cannot actually turn off the lights while the car is driving or in any gear but park. If you would want to turn the lights off while you are parked for some reason, put the car in park, turn off the car completely, pull the emergency brake up, then restart the car. This overrides the headlights and they will stay off while the car is running-however, as soon as you release the emergency brake- the headlights turn back on.

If your car has daytime running lights (standard in Canada) then the only way to turn on just the parking lights is when the car is in park or neutral, the light switch is in the park light position and the parking brake is on. Then the headlights will turn off. Any other configuration means the headlights will be on. On this car, parking lights can truly only be used when parked!
