9-54 Driving and Operating
If the fuel cap is not installed
properly, the TIGHTEN GAS CAP
message will appear on the Driver
Information Center display. See
When reinstalling the cap, turn it
clockwise until it clicks once,
otherwise the Malfunction Indicator
Lamp could turn on. See
.
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.
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
When replacing the fuel cap, turn it
clockwise until it clicks once. 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
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.
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
