Before driving
CAUTION
■
Refueling the vehicle
Observe the following precautions while refueling the vehicle.
Failure to do so may result in death or serious injury.
●Touch the vehicle or some other metal surface to discharge any static
electricity.
Sparks resulting from discharging static electricity may cause the fuel
vapors to ignite.
● 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 of the filler neck and cause
injury.
● Do not allow anyone that has not discharged static electricity from their
bodies 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 replacing the fuel cap
Do not use anything but a genuine Toyota fuel tank cap designed for your
vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.
