 Confirm the type of fuel. ■
Fuel types
→ P.408■
Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehi-
cle has a fuel tank opening that only accom-
modates the special nozzle on unleaded

Before refueling the vehicle
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 ve hicle and before
opening the fuel door, touch an
unpainted metal surface to discharge
any static electricity. It is important to
discharge static electricity before refu-
eling 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 of the filler neck and cause injury.
●
Do not allow anyone that has not dis-
charged 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 vehi-
cle.
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 elec-
tricity to build up, re sulting 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 noz-
zle 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, damaging fuel sys-
tem components or the vehicle’s painted
surface.
