I had this trouble with my Peugeot it was where the manual said but because it was in dark area and painted black couldn't see it but once found wrapped flourenscent tape around the handle. when you find it, some pull up, some push in or down. some pull out some pull left or right so try every which way.
An alternative nip in nearby garage workshop and plead with them as to where it is.
Sorry it's not more specific
