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, wait 10  
seconds and try again.  
2
Make sure the parking brake is on.  
3
Depress the accelerator all the way and hold it there.  
4
Depress the clutch pedal (Manual transaxle) or the brake pedal  
(Automatic transaxle), then press the push button start. If the  
engine starts, release the accelerator immediately because the  
engine will suddenly rev up.  
5
If the engine fails to start, crank it without depressing the accelera-  
tor.  
If the engine still does not start using the above procedure, have your  
vehicle inspected by your Toyota dealer.
