Q. Does Maruti Suzuki S-Presso has rear parking camera?

No. But from showroom itself they installed aftermarket item. There's no guiding red yellow lines you get. So you have to use it alongwith the sensors to identify how close you are from an object behind you.

Rearview camera can be installed in the infotainment system but doesn't support parking guidelines. RVC without guidelines does not serve any purpose

You can add as addl accessories. Costed around 3000 rs
