While refueling, let the cap hang by the tether
below the fuel fill opening.
CAUTION:
{
Fuel can spray out on you if you open the
fuel cap too quickly. If you spill fuel and
then something ignites it, you could be
badly burned. 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 411.
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
326
has been left off or improperly installed. This would
allow fuel to evaporate into the atmosphere. See
Malfunction Indicator Lamp on page 200.
The CHECK 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 214 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/retailer 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.
