With Chewbacca, this point is a bit of a Dymo-sore.
It can be amusing to put PCs in charge of a vehicle with controls that they have no idea how to operate. For extra fun, actually have the controls labelled. In a foreign/alien language. Or with incorrect labels.
The venerable roleplaying game Paranoia did a version of this in one of its published adventures. The PCs had to attempt to use a vehicle and were given a printout drawing of the vehicle's control panel, and no instructions other than to tell the GM what buttons they wanted to push or levers to pull.

C-3PO: Are you nervous about meeting your mother again?
Leia: No.
Luke: Yes.
Leia: She had me locked up on the old Peace Moon for days. She doesn't scare me any more.
Luke: Yeah, apparently she didn't feel the need to dissect you with a laser sword.
Chewbacca: I have a bad feeling about this.
Han: It'll be fun!
Luke: Storming a fully armed battle station to confront your evil psycho mother isn't exactly what I'd call fun.
Chewbacca: Entering hyperspace.
Chewbacca: By just pressing this button, which is elegantly engraved "Hyperspace". Instead of having to pull two wires out of a console and spark them.
Han: Hey, I labelled those wires!
