Filling the Tank
{CAUTION:
Fuel vapor burns violently and a fuel re
can cause bad injuries. To help avoid
injuries to you and others, read and follow
all the instructions on the pump island.
Turn off your engine when you are
refueling. Do not smoke if you are near fuel
or refueling your vehicle. Keep sparks,
ames, and smoking materials away
from fuel. Do not leave the fuel pump
unattended when refueling your vehicle.
This is against the law in some places.
Keep children away from the fuel pump;
never let children pump fuel.The fuel cap is located
on the driver’s side of
the vehicle.
Some vehicles may be equipped with a fuel door.
Open the door to access the fuel cap.
Some vehicles may be equipped with a locking
fuel cap. Use the fuel cap key to unlock the
fuel cap. If you ever need a replacement key,
your dealer can help you get one.

{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 overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon as
possible. SeeWashing Your Vehicle on page 495.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. SeeMalfunction Indicator Lamp
on page 215.
The TIGHTEN FUEL CAP message will be
displayed on the Driver Information Center (DIC)
if the fuel cap is not properly installed.
SeeDIC Warnings and Messages on page 226
for more information.

ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.

label.2. You can remove the coolant surge tank
pressure cap when the cooling system,
including the coolant surge tank pressure cap
and upper radiator hose, are no longer hot.
Turn the pressure cap slowly counterclockwise
about one full turn.
If you hear a hiss, wait for that to stop. A hiss
