title: Paddock Quick Reference
description: One-click access to the pages most often needed in the paddock — debugging, torque values, fluids, alarms, and the latest service bulletins.
---

The pages a tech or driver hits most when the car is at the track. Links land on specific sections where possible.

:::note
**Offline / no signal in the paddock?** [Download the latest PDF edition of the manual](https://data.rush.sr/manual/rush-sr-manual.pdf) before you head to the track.
