CAUTION:
{
If you spill fuel and then something
ignites it, you could be badly burned.
Fuel can spray out on you if you open
the fuel cap too quickly. This spray can
happen if your tank is nearly full, and is
more likely in hot weather. Open the fuel
cap slowly and wait for any hiss noise to
stop. Then unscrew the cap all the way.
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 541.
When replacing the fuel cap, turn it clockwise
until it clicks. It will require more effort to turn
the fuel cap on the last turn as you tighten it.
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 250.
The TIGHTEN GAS CAP message will be
displayed on the Driver Information Center (DIC)
if the fuel cap is not properly installed. See
DIC Warnings and Messages on page 267 for
more information.
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 250.
