Filling Your Tank - Chevrolet 2003 Astro Owner's Manual

Filling Your Tank
Fuel vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don't smoke if you're near fuel or refueling
your vehicle. Keep sparks, flames and smoking
materials away from fuel.
The tethered fuel cap is behind a hinged door on the
driver's side of your vehicle.
