If you see a red exclamation mark inside a red circle on the dashboard, it means the parking brake is on.
Always release the parking brake before driving your Spaceship.
Spaceships campervans use a foot-operated parking brake located next to the brake pedal (on the far left). Press it firmly with your foot to engage or release it.
Once the parking brake is released, the warning light will turn off and you can drive normally (make sure the gear is in D – Drive).
