uuRefueling uHow to Refuel
Driving
How to Refuel
Your fuel tank is not equipped with a fuel filler cap. You can insert the filler nozzle
directly into the filler neck. The tank seal s itself again when you pull out the filler
nozzle.
1.Stop your vehicle with the service station
pump on the left side of the vehicle in the
rear.
2. Turn off the engine.
3. Press the fuel fill door release button.
u The fuel fill door opens.1How to Refuel
The fuel filler opening is designed to accept only
service station filler nozzles for refueling. Use of
smaller diamet er tubes (e.g., those used to siphon
fuel for other uses) or other non-service station
devices can damage the area in and around the filler
opening.
The filler nozzle automatically stops to leave space in
the fuel tank so that fuel does not overflow as a result
of changes in air temperature.
Do not continue to add fuel after the filler nozzle has
automatically stopped. Addi tional fuel can exceed
the full tank capacity.
3WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured
when handling fuel.
• Stop the engine, and keep heat, sparks,
and flames away.
• Handle fuel only outdoors.
• Wipe up spills immediately.

4. Place the end of the filler nozzle on the
lower part of filler opening, then insert it
slowly and fully.
u Make sure that the end of the filler
nozzle goes down along with the filler
pipe.
u Keep the filler nozzle level.
u When the tank is full, the filler nozzle will
click off automatically.
u If you do not fill up the tank to full,
always add a minimum of 3.5 US gal
(13.3 L) of fuel.
u After filling, wait about five seconds
before removing the filler nozzle.
5. Shut the fuel fill door by hand.1How to Refuel
If the filler nozzle keeps tu rning off when the tank is
not full, there may be a pr oblem with the pump’s fuel
vapor recovery system. Try fi lling at another pump. If
this does not fix the problem, consult a dealer.
If you repeatedly fill the tank with less than the
specified minimum amount of fuel, the malfunction
indicator lamp may come on. If this happens, have
your vehicle checked by a dealer.
If you have to refuel y our vehicle from a portable
container, use the funnel pr ovided with your vehicle.
