Be careful not to spill fuel. Do not top off or overfill
the tank and wait a few seconds after you have
finished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon
as possible. See Washing Your Vehicle on
page 349.
When replacing the fuel cap, turn it clockwise until
it clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the fuel
cap has been left off or improperly installed.
This would allow fuel to evaporate into the
atmosphere. See Malfunction Indicator Lamp on
page 180.
CAUTION:
{
If a fire starts while you are refueling, do
not remove the nozzle. Shut off the flow
of fuel by shutting off the pump or by
notifying the station attendant. Leave the
area immediately.
Notice: If you need a new fuel cap, be sure
to get the right type. Your dealer can get
one for you. If you get the wrong type, it
may not fit properly. This may cause your
malfunction indicator lamp to light and
may damage your fuel tank and emissions
system. See Malfunction Indicator Lamp
on page 180.
