The DRL system is available on models for the Canadian market and provides forcibly turning on the headlights 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.
In DRL mode, the headlights operate in economy mode, which avoids premature lamp failure.
