2007 PONTIAC GRAND PRIX fuel pump

When the indicator nears empty, there is still a
little fuel left, but you should get more soon.
Here are four things owners usually ask about the
fuel gage. All these situations are normal and
do not indicate a problem with the fuel gage:
At the gas station the pump shuts off before
the gage reads full.
It takes more or less fuel to ll up than the
gage indicates. For example, the gage
reads half full, but it took more or less than
half the tank’s capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate full when the
ignition is turned off.
Driver Information Center (DIC)
The Driver Information Center (DIC) gives
important safety and maintenance facts. When the
vehicle’s ignition is turned on, all of the DIC
lights illuminate for a few seconds and an
introductory message will appear. After this, the
DIC will begin working.
DIC Controls and Displays
(Base Level DIC)
The Driver Information Center (DIC) control
buttons and the message display screen are
located above the radio. The DIC gives important
safety and maintenance facts concerning the
vehicle. The status of many of the vehicle’s
systems along with driver personal programming
mode menus and warning messages about
the vehicle’s systems may display on the DIC
screen.
The vehicle’s transaxle position will also appear.
The buttons on the base level are trip odometer,
set/reset, and options.

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 tethered fuel cap is located behind a hinged
fuel door on the driver’s side of the vehicle.
To remove the fuel cap, turn it slowly
counterclockwise. The fuel cap has a spring in it; if
the cap is released too soon, it will spring back
to the right.
While refueling, let the fuel cap hang by the tether
below the fuel ll opening.

{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 453.
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 180.The CHECK GAS 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 200for more
information.
{CAUTION:
If a re starts while you are refueling, do
not remove the nozzle. Shut off the ow 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
t 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 180.

Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it
is in your vehicle. Static electricity
discharge from the container can ignite the
gasoline vapor. You can be badly burned
and your vehicle damaged if this occurs.
To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup
bed, or on any surface other than the
ground.
Bring the ll nozzle in contact with the
inside of the ll opening before
operating the nozzle. Contact should
be maintained until the lling is
complete.
Do not smoke while pumping gasoline.
Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start
up and injure you even when the engine
is not running. Keep hands, clothing,
and tools away from any underhood
electric fan.
{CAUTION:
Things that burn can get on hot engine
parts and start a re. These include
liquids like fuel, oil, coolant, brake uid,
windshield washer and other uids, and
plastic or rubber. You or others could be
burned. Be careful not to drop or spill
things that will burn onto a hot engine.
