The DRL system is available on models for the Canadian market and forces the headlights to turn on when the engine is running. You can turn off the headlights without turning off the engine by cocking the parking brake. After the parking brake is released, the headlights will remain on until the ignition is turned off, even if the brake is re-cocked.
When the DRL system is activated, the headlights operate in economy mode, which helps to avoid premature lamp failure.
