2009 HUMMER H3 mileage

Speedometer and
Odometer
The speedometer shows the speed
in both miles per hour (mph) and
kilometers per hour (km/h).
The odometer shows how far the
vehicle has been driven, in
either miles (used in the United
States) or kilometers (used in
Canada).
The odometer mileage can be
checked without the vehicle running
by pressing the trip information
stem. See “Odometer” underDIC
Operation and Displays on
page 3-34for more information.
If the cluster is replaced the
new one will automatically detect
and update the vehicle’s
accumulated mileage.
Trip Odometer
The vehicle has a trip odometer that
indicates how far the vehicle has
been driven since the trip odometer
was last set to zero.
See “Trip Odometer” underDIC
Operation and Displays on
page 3-34for more information.
Tachometer
The tachometer displays the
engine speed in revolutions per
minute (rpm).
Notice:If the engine is operated
while the tachometer is in the
shaded warning area, the vehicle
could be damaged, and the
damages would not be covered
by the vehicle warranty. Do
not operate the engine with the
tachometer in the shaded
warning area.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
When the engine is started, a chime
sounds for several seconds to
remind the driver to fasten their
safety belt, unless it is already
buckled.
The safety belt light comes on and
stays on for several seconds,
then ashes for several more.
This chime and light are repeated if
the driver safety belt remains
unbuckled and the vehicle is in
motion. If the driver safety belt is
already buckled, neither the
chime nor the light comes on.

Your Driving, the
Road, and the Vehicle
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
Avoid fast starts and accelerate
smoothly.
Brake gradually and avoid abrupt
stops.
Avoid idling the engine for long
periods of time.
When road and weather
conditions are appropriate, use
cruise control, if equipped.
Always follow posted speed limits
or drive more slowly when
conditions require.
Keep vehicle tires properly
inated.
Driving Your Vehicle 4-1

If doing some of your own service
work, use the proper service manual.
It tells you much more about how to
service the vehicle than this manual
can. To order the proper service
manual, seeService Publications
Ordering Information on page 7-15.
This vehicle has an airbag system.
Before attempting to do your own
service work, seeServicing Your
Airbag-Equipped Vehicle on
page 1-58.
Keep a record with all parts receipts
and list the mileage and the date
of any service work performed. See
Maintenance Record on page 6-16.
Adding Equipment to the
Outside of the Vehicle
Things added to the outside of the
vehicle can affect the airow
around it. This can cause wind
noise and can affect fuel economy
and windshield washer performance.
Check with your dealer/retailer
before adding equipment to
the outside of the vehicle.
Fuel
Use of the recommended fuel is
an important part of the proper
maintenance of this vehicle.
To help keep the engine clean
and maintain optimum vehicle
performance, we recommend the
use of gasoline advertised as
TOP TIER Detergent Gasoline.
Gasoline Octane
Use regular unleaded gasoline with
a posted octane rating of 87 or
higher. If the octane rating is less
than 87, you might notice an audible
knocking noise when you drive,
commonly referred to as spark
knock. If this occurs, use a gasoline
rated at 87 octane or higher as
soon as possible. If you are using
gasoline rated at 87 octane or higher
and you hear heavy knocking, the
engine needs service.
Gasoline Specications
At a minimum, gasoline should
meet ASTM specication
D 4814 in the United States or
CAN/CGSB-3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeAdditives on
page 5-6for additional information.
California Fuel
If the vehicle is certied to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specications.
See the underhood emission control
label. If this fuel is not available
in states adopting California
emissions standards, the vehicle
will operate satisfactorily on
fuels meeting federal specications,
but emission control system
performance might be affected.
Service and Appearance Care 5-5

GM6094M
Use only an oil that meets
GM Standard GM6094M.
SAE 5W-30
SAE 5W-30 is best for the
vehicle. These numbers on an
oil container show its viscosity,
or thickness. Do not use
other viscosity oils such as
SAE 20W-50.
American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst symbol
on the container. This symbol
indicates that the oil has been
certied by the American
Petroleum Institute (API).Notice:Use only engine oil
identied as meeting GM
Standard GM6094M and showing
the American Petroleum
Institute Certied For Gasoline
Engines starburst symbol. Failure
to use the recommended oil
can result in engine damage not
covered by the vehicle warranty.
Cold Temperature Operation
If in an area of extreme cold, where
the temperature falls below−20°F
(−29°C), use either an SAE 5W-30
synthetic oil or an SAE 0W-30
engine oil. Both provide easier cold
starting for the engine at extremely
low temperatures. Always use
an oil that meets the required
specication, GM6094M. See “What
Kind of Engine Oil to Use” for
more information.
Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with
the starburst symbol that meet
GM Standard GM6094M are all that
is needed for good performance
and engine protection.
Engine oil system ushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and lter. This is based on
engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions,
the mileage at which an oil change
is indicated can vary considerably.
For the oil life system to work
properly, the system must be reset
every time the oil is changed.
Service and Appearance Care 5-15

Owner Checks and
Services
These owner checks and services
should be performed at the
intervals specied to help ensure
vehicle safety, dependability,
and emission control performance.
Your dealer/retailer can assist
with these checks and services.
Be sure any necessary repairs are
completed at once. Whenever
any uids or lubricants are added
to the vehicle, make sure they
are the proper ones, as shown
inRecommended Fluids and
Lubricants on page 6-12.
At Each Fuel Fill
It is important to perform these
underhood checks at each fuel fill.
Engine Oil Level Check
Notice:It is important to check
the engine oil regularly and
keep it at the proper level.
Failure to keep the engine oil
at the proper level can cause
damage to the engine not covered
by the vehicle warranty.
Check the engine oil level and
add the proper oil if necessary.
SeeEngine Oil on page 5-13.
Engine Coolant Level Check
Check the engine coolant level
and add DEX-COOL®coolant
mixture if necessary. SeeEngine
Coolant on page 5-23.
Windshield Washer Fluid
Level Check
Check the windshield washer uid
level in the windshield washer
uid reservoir and add the proper
uid if necessary.
At Least Once a Month
Tire Ination Check
Inspect the vehicle’s tires and make
sure they are inated to the correct
pressures. Do not forget to check
the spare tire. SeeInflation - Tire
Pressure on page 5-51. Check to
make sure the spare tire is stored
securely. SeeChanging a Flat Tire
on page 5-66.
Tire Wear Inspection
Tire rotation may be required for
high mileage highway drivers prior to
the Engine Oil Life System service
notication. Check the tires for
wear and, if necessary, rotate the
tires. SeeTire Inspection and
Rotation on page 5-57.
