In Case of an Emergency Emergency Starting Starting a Flooded Engine If the engine fails to start, it may be flooded (excessive fuel in the engine). Follow this procedure: 1. If the engine does not start within 5 seconds on the first try, turn the key to the LOCK position, wait 10 seconds and try again. 2. Depress the accelerator all the way and hold it there. 3. Turn the ignition switch to the START position and hold it there―for up to 10 seconds. If the engine starts, release the key and accelerator immediately because the engine will suddenly rev up. 4. If the engine fails to start, crank it without depressing the accelerator―for up to 10 seconds. If the engine still does not start using the above procedure, have your vehicle inspected by an Authorized Mazda Dealer. 7-16
