2009 CHEVROLET HHR fuel pump

Fuel Gage
The fuel gage indicates
about how much fuel is left
in the fuel tank.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
Here are four things that some owners ask about. None
of these show a problem with the fuel gage:
At the service station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the fuel tank’s capacity
to ll it.
The gage moves a little when the vehicle turns a
corner or speeds up.
The gage does not go back to empty when the
ignition is turned off.
For the fuel tank capacity, seeCapacities and
Specifications on page 5-114.
Boost Gage
For vehicles with this gage, it indicates vacuum during
light to moderate throttle and boost under heavier
throttle.

TIRE PRESSURES:Displays the last gage tire
pressures recorded from each of the wheel mounted
tire pressure sensors.
Readouts #3
BAROMETER:Displays ambient air pressure as
measured by the engine’s ambient pressure sensor.
OUTSIDE TEMPERATURE:Displays ambient
temperature as measured by an outside air temperature
sensor.
BATTERY VOLTAGE:Displays the vehicle’s battery
voltage.
Readouts #4

sensor.
INLET AIR TEMPERATURE:Displays the
instantaneous temperature of the air at the inlet to the
induction system.
FUEL PRESSURE:Displays fuel pressure as
measured by a sensor on the output of the

INDICATORS
The indicators come on when the corresponding function
is actively working to stabilize or control the vehicle. Each
indicator light on the RPD display can be turned on and
off using the SETUP MENU. These indicators work
independently of the telltales on the instrument panel
cluster. Turning the indicator on the RPD display on or off
does not enable or disable the functions on the vehicle.
This indicator comes on whenever the vehicle
StabiliTrak
®is actively working.

Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines might be available in
your area. We recommend that you use these gasolines,
if they comply with the specications described earlier.
However, E85 (85% ethanol) and other fuels containing
more than 10% ethanol must not be used in vehicles that
were not designed for those fuels.
Notice:This vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in the fuel
system and also damage plastic and rubber parts.
That damage would not be covered under the vehicle
warranty.
Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. We recommend against
the use of such gasolines. Fuels containing MMT can
reduce the life of spark plugs and the performance
of the emission control system could be affected.
The malfunction indicator lamp might turn on. If this
occurs, return to your dealer/retailer for service.Fuel E85 (85% Ethanol)
The 8th digit of the Vehicle Identication Number (VIN)
shows the code letter or number that identies the
vehicle’s engine. The VIN is at the top left of the
instrument panel. SeeVehicle Identification Number
(VIN) on page 5-107.
If your vehicle has the 2.2L L4 engine (VIN Code B)
or the 2.4L L4 engine (VIN Code V), you can use either
unleaded gasoline or ethanol fuel containing up to
85% ethanol (E85). SeeFuel on page 5-5. In all other
engines, use only the unleaded gasoline described
underGasoline Octane on page 5-5.
Only vehicles that have the 2.2L L4 engine (VIN Code B)
or the 2.4L L4 engine (VIN Code V) can use 85% ethanol
fuel (E85). We encourage the use of E85 in vehicles
that are designed to use it. The ethanol in E85 is a
“renewable” fuel, meaning it is made from renewable
sources such as corn and other crops.
Many service stations will not have an 85% ethanol
fuel (E85) pump available. The U. S. Department
of Energy has an alternative fuels website
(www.eere.energy.gov/afdc/infrastructure/locator.html)
that can help you nd E85 fuel. Those stations that
do have E85 should have a label indicating ethanol
content. Do not use the fuel if the ethanol content
is greater than 85%.

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 the engine when you are
refueling. Do not smoke if you are near fuel or
refueling the vehicle. Do not use cellular phones.
Keep sparks, ames, and smoking materials away
from fuel. Do not leave the fuel pump unattended
when refueling the vehicle. This is against the law
in some places. Do not re-enter the vehicle while
pumping fuel. Keep children away from the fuel
pump; never let children pump fuel.To open the fuel door, push the rearward center edge in
and release and it will open.

The tethered fuel cap is located behind a hinged
fuel door on the passenger side of the vehicle. If the
vehicle has E85 fuel capability, the fuel cap will be
yellow and state that E85 or gasoline can be used.
SeeFuel E85 (85% Ethanol) on page 5-7.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, hang the tethered fuel cap from the
hook on the fuel door.
{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 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 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 5-103.
5-10

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 3-37.
The CHECK GAS CAP message displays on the Driver
Information Center (DIC) if the fuel cap is not properly
installed. SeeDIC Warnings and Messages on
page 3-50for more information.
To close the fuel door securely, push the door to the
closed position.
{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/retailer can get one
for you. If you get the wrong type, it may not t
properly. This may cause the malfunction indicator
lamp to light and may damage the fuel tank and
emissions system. SeeMalfunction Indicator Lamp
on page 3-37.
5-11

Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it is in the
vehicle. Static electricity discharge from the
container can ignite the fuel vapor. You can be
badly burned and the vehicle damaged if this
occurs. To help avoid injury to you and others:
Dispense fuel 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 fuel.
Do not use a cellular phone while
pumping fuel.
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.
