452 STARTING AND OPERATING
3. There is no fuel filler cap. A flapper door inside the
pipe seals the system.
4. Insert the fuel nozzle fully into the filler pipe – the
nozzle opens and holds the flapper door while refuel-
ing.
NOTE: Only the correct size nozzle opens the latches
allowing the flapper door to open.
5. Fill the vehicle with fuel – when the fuel nozzle
"clicks" or shuts off the fuel tank is full.
6. Remove the fuel nozzle and close the fuel door.
NOTE: A funnel is provided (located in the trunk in the
spare tire area) to open the flapper door to allow for
emergency refueling with a gas can.
Fuel Funnel
CAUTION!
To avoid fuel spillage and overfilling, do not "top
off" the fuel tank after filling.
