{WARNING
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 the 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.
Do not top off or overfill the tank and
wait a few seconds before removing
the nozzle. Clean fuel from painted
surfaces as soon as possible.
See Exterior Care on page 10‑92.
{WARNING
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 a new fuel cap is
needed, be sure to get the right
type of cap from your dealer.
The wrong type of fuel cap might
not fit properly, might cause the
malfunction indicator lamp to
light, and could damage the
fuel tank and emissions system.
See Malfunction Indicator Lamp
on page 5‑17.

Container
{WARNING
Never fill a portable fuel container
while it is in the vehicle. Static

and the vehicle damaged if this
occurs. To help avoid injury to
you and others:
.Dispense fuel only into
approved containers.
.Do not fill a container while
it is inside a vehicle, in a
