Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehi cle has a fuel tank opening that only accom-
modates the specia l nozzle on unleaded fuel pumps.
Opening the fuel tank cap Perform the following steps to open the fuel tank cap:
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 vehicle and before opening the fuel door, touch an unpainted metal
surface to discharge any static electricity. It is important to discha rge static electricity
before refueling because sparks resulting fr om 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 fu el 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 th at 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 pe rson 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 nozz le into the fuel filler neck.●
Stop filling the tank after the fuel nozzle automatically clicks off.●
Do not top off the fuel tank.

RC F_U NOTICE ■
Notice on fuel quality ●
Do not use improper fuels. If improper fuels are used, the engine will be damaged. ●
Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic converters
causing the emission control system to malfunction. ●
Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance problems. ●
Using unleaded gasoline with an octane numb er or rating lower than the level previ-
ously stated may cause pe rsistent heavy knocking.
At worst, this may lead to engine da mage and will void the vehicle warranty.■
Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is encoun-
tered after using a different type of fuel, discontinue the use of that type of fuel.■
When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.
