WARNING  
When refueling the vehicle  
Observe the following precautions while refueling the vehicle. Failure to do  
so may result in death or serious injury.  
After exiting the vehicle and before opening the fuel door, touch an  
unpainted metal surface to discharge any static electricity. It is important to  
discharge static electricity before refueling because sparks resulting from  
static electricity can cause fuel vapors to ignite while refueling.  
Always hold the grips on the fuel tank cap and turn it slowly to remove it.  
A whooshing sound may be heard when the fuel tank cap is loosened.  
Wait until the sound cannot be heard before fully removing the cap. In hot  
weather, pressurized fuel may spray out the filler neck and cause injury.  
Do not allow anyone that has not discharged static electricity from their  
body to come close to an open fuel tank.  
Do not inhale vaporized fuel.  
Fuel contains substances that are harmful if inhaled.  
Do not smoke while refueling the vehicle.  
Doing so may cause the fuel to ignite and cause a fire.  
Do not return to the vehicle or touch any person or object that is statically  
charged.  
This may cause static electricity to build up, resulting in a possible ignition  
hazard.  
When refueling  
Observe the following precautions to prevent fuel overflowing from the fuel  
tank:  
Securely insert the fuel nozzle into the fuel filler neck.  
Stop filling the tank after the fuel nozzle automatically clicks off.  
Do not top off the fuel tank.  
NOTICE  
Refueling  
Do not spill fuel during refueling.  
Doing so may damage the vehicle, such as causing the emission control  
system to operate abnormally or damaging fuel system components or the  
vehicle’s painted surface.
