2009 HUMMER H3 fuel

Instrument Panel Cluster
The instrument panel cluster is designed to indicate at a glance how the vehicle is running. It tells how fast the
vehicle is going, about how much fuel is being used, and many other things needed to drive safely and economically.United States 3.7L L5 Automatic Transmission version shown, 5.3L V8, Canada and Manual Transmission similar

Tire Pressure Light
The tire pressure light should come
on briey as the engine is started.
If it does not, have the vehicle
service by your dealer/retailer. It
provides information about tire
pressures and the Tire Pressure
Monitoring System.
When the Light is On Steady
This indicates that one or more of
the tires are signicantly
underinated.
A tire pressure message in the
Driver Information Center (DIC),
may accompany the light. SeeDIC
Warnings and Messages on
page 3-37for more information.
Stop and check the tires as soon as
it is safe to do so. If underinated,
inate to the proper pressure.
SeeTires on page 5-44for more
information.When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System. The light ashes
for about a minute and stays
on steady for the remainder of the
ignition cycle. This sequence
will repeat with every ignition cycle.
SeeTire Pressure Monitor System
on page 5-52for more information.
Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures
that emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.This light comes on when the
ignition is on, but the engine is not
running, as a check to show it
is working. If it does not, have the
vehicle serviced by your
dealer/retailer.
If the check engine light comes on
and stays on, while the engine
is running, this indicates that there
is an OBD II problem and service
is required.
Malfunctions often are indicated by
the system before any problem
is apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system
assists the service technician in
correctly diagnosing any
malfunction.
Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
3-30 Instrument Panel

the vehicle’s fuel economy might
not be as good, and the engine
might not run as smoothly.
This could lead to costly repairs
that might not be covered by
the vehicle warranty.
Notice:Modications made to
the engine, transmission,
exhaust, intake, or fuel system of
the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle’s emission
controls and can cause this light
to come on. Modications to
these systems could lead
to costly repairs not covered by
the vehicle warranty. This
could also result in a failure to
pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications
on page 5-3.This light comes on during a
malfunction in one of two ways:
Light Flashing:A misre condition
has been detected. A misre
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
If the light continues to ash, when
it is safe to do so, stop the
vehicle. Find a safe place to park
the vehicle. Turn the key off, wait at
least 10 seconds, and restart the
engine. If the light is still ashing,
follow the previous steps and
see your dealer/retailer for service
as soon as possible.Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
An emission system malfunction
might be corrected by:
Make sure the fuel cap is fully
installed. SeeFilling the Tank
on page 5-7. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel
to evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn
the light off.
If the vehicle has been driven
through a deep puddle of
water, the vehicle’s electrical
system might be wet. The
condition is usually corrected
when the electrical system dries
out. A few driving trips should
turn the light off.
Instrument Panel 3-31

Make sure to fuel the vehicle
with quality fuel. Poor fuel
quality causes the engine not to
run as efficiently as designed
and may cause: stalling
after start-up, stalling when the
vehicle is changed into gear,
misring, hesitation on
acceleration, or stumbling on
acceleration. These conditions
might go away once the engine is
warmed up.
If one or more of these conditions
occurs, change the fuel brand
used. It will require at least
one full tank of the proper fuel to
turn the light off.
SeeGasoline Octane on
page 5-5.
If none of the above have made the
light turn off, your dealer/retailer
can check the vehicle. The
dealer/retailer has the proper test
equipment and diagnostic tools to x
any mechanical or electrical
problems that might have
developed.Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on the vehicle.
Failure to pass this inspection could
prevent getting a vehicle
registration.
Here are some things to know to
help the vehicle pass an inspection:
The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in the
ON/RUN and the light is not on.
The vehicle will not pass
this inspection if the OBD II
(on-board diagnostic) system
determines that critical emission
control systems have not
been completely diagnosed by
the system. The vehicle would be
considered not ready for
inspection. This can happen if
the battery has recently been
replaced or if the battery has rundown. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving. If
this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your
dealer/retailer can prepare the
vehicle for inspection.
Oil Pressure Light
{CAUTION
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches re.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
3-32 Instrument Panel

Notice:Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule in this manual for
changing engine oil.
The oil pressure light should come
on briey as the engine is started.
If it does not come on have the
vehicle serviced by your
dealer/retailer.
If the light comes on and stays on, it
means that oil is not owing
through the engine properly. The
vehicle could be low on oil and
might have some other system
problem.Security Light
For information regarding this light
and the vehicle’s security system,
seeContent Theft-Deterrent
on page 2-11.
Cruise Control Light
This light comes on whenever the
cruise control is set.
The light goes out when the cruise
control is turned off. SeeCruise
Control on page 3-9for more
information.
Highbeam On Light
This light comes on when the
high-beam headlamps are in use.
SeeHeadlamp High/Low-Beam
Changer on page 3-7for more
information.
Fuel Gage
The fuel gage indicates about how
much fuel there is remaining in
the fuel tank. The ignition must be
in ON/RUN.
United StatesCanada
Instrument Panel 3-33

An arrow on the fuel gage indicates
the side of the vehicle the fuel
door is on.
Here are three things that can
happen but do not indicate a
problem with the fuel gage:
At the gas 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 tank’s
capacity to ll the tank.
The gage moves a little when
turning a corner or speeding up.
When the fuel in the fuel tank is low,
a LOW FUEL message displays
on the Driver Information
Center (DIC). SeeDIC Warnings
and Messages on page 3-37
for more information.
