Mostly mildly scantly women, but it was very sexual. One must keep in mind, this was a different time. The Production Code for TV and motion pictures had just ended not too long before this movie (just 7 years prior in 1968). There were subliminal things that were common even in that time, that are actually R-rated. Calling woman "pu**ycats" for instance was common during the Code. "Gaylord" too.

This movie was likely an R, and maybe a hard one at that, edited somewhat to get a PG. It was like "Poltergeist" (which came 7 years later), which was a hard R originally, trimmed down to get a PG, except this movie has a code unlike the Jerry Goldsmith-composed production.

Some moderate violence, sometimes serious, but some scenes are more comical (such as one of Pilot's henchman being threatened by Sheba, to have his head messed up badly by the car washing machines, it's played for laughs). This is a comedy action movie, after all. Hence one reason this movie didn't outright become R-rated.

There's a very nasty scene where some racist Yankees rob the place of our protagonist's father. Fairly graphic shooting, borderline R-rated, but not too graphic. Her father is badly hurt.

Some bloodshed.

Some moderate language. Not too explicit. But again this is a product of a different time, not too long after the Code ended in 1968 (this movie was 1975). In the 1975, it was still common for men to say "p*ssycat" as a compliment and a pet name for women. Subliminal but true. "Gaylord" as a name could mean a man was gay, or metrosexual at least (sometimes gay-bashing). Anyways, in today's standard's "p...ycat" is vulgar and profane. Not in the old days even though it was controversial then.

The cursing is a reason this movie was originally R. R-rated cursing at times. One or two or three F-words. Also because of racial slurs. "N...r" is used at least twice, in a very nasty way too.

Some other curses as well, such as "slut" and "sh*t" and "son of a b**ch" and "bastard."

Some mild smoking, although this movie glorifies it, which could make it an R today.

Some intense moments, but being this was 1975, and technology wasn't as advanced, the situations come off as more comical than violent. Add to that, the comical nature of our main big bad (Pilot). And this is a funny movie at times. Nothing too serious, but still moderate
