1. Add Gas: This is the most crucial step. Locate the nearest gas station and fill your tank with gasoline. It's a good idea to add at least 5 gallons to ensure the fuel pump is properly primed.
2. Turn the Ignition Key (or Press the Start Button): Once you've added gas, get back in your car and attempt to start it normally. If it doesn't start immediately, don't panic. The fuel pump may need a few seconds to prime the system.
3. Wait and Try Again: Give it a few seconds to a minute and try again. The fuel pump will push gas to the engine.
4. If it Still Doesn't Start: There could be additional issues, even if unrelated to running out of gas. Check these possibilities:
* Dead Battery: Running out of gas can sometimes drain the battery if you tried repeatedly to start it. Try jump-starting your Subaru.
* Fuel Pump Issues (Rare but Possible): In rare cases, running completely out of gas can damage the fuel pump. This is less likely with modern fuel-injected cars. If the problem persists, it would need professional diagnosis.
Important Note: Repeated attempts to start a car with an empty tank can strain the battery and possibly damage the starter motor. Avoid cranking the engine for extended periods.
