The DRL function in the new Fortuner are by design.
The DRLs in the headlamps will only turn on in the day-time, with the parking brake down, car out of Park and with daylight. The position lamps/clearance lamps have moved at the bottom and will turn on whether night-time or day-time (but with the parking brake down).
Previous model's DRLs functioned both as DRL and clearance lamp, that's why they remained on at all times.
