Like the majority of modern cars the 500X only has front DRL (daylight running lights), there are no rear DRL's on the car. Annoyingly the car lights up front and rear lights when you unlock, but the rears quickly extinguish to front only. Worth being in mind if you are driving and daylight drops, you will see some light from the front of the car but nothing from the back. Not worth risking a fine.
There is no sidelight position, only dipped main/rear on and off. Sidelights are a bit of an overhang of the old days of motoring when streetlights were not as commonplace (and cars were not covered in reflective surfaces) and as such are largely obsolete on modern cars now.
Basically if you need to light up, it's the light dial to 1 (0 being front DRL only). Then toggle full beam if you need it. Just in case it helps, fog lights are within the light dial, top is front, bottom is rear. there is only one rear fog but dual front. Apologies if that's teaching you to suck eggs!
Hope that helps,
