2009 HUMMER H3 transmission fluid

Before Leaving on a
Long Trip
To prepare your vehicle for a long
trip, consider having it serviced
by your dealer/retailer before
departing.
Things to check on your own
include:
Windshield Washer Fluid:
Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All
levels checked?
Lamps:Do they all work and are
lenses clean?
Tires:Are treads good? Are tires
inated to recommended
pressure?
Weather and Maps:Safe to
travel? Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving. If
you become tired or sleepy, nd
a safe place to park your vehicle
and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on at or rolling terrain. Tips for
driving in these conditions include:
Keep the vehicle serviced
and in good shape.
Check all uid levels and brakes,
tires, cooling system, and
transmission.
Going down steep or long hills,
shift to a lower gear.
{CAUTION
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

Checking Engine Oil
It is a good idea to check the
engine oil every time you get fuel.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. SeeEngine
Compartment Overview on
page 5-10for the location of the
engine oil dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If you do not
do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it
with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the
tip down, and check the level.

Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
A good time to check the automatic
transmission uid level is when
the engine oil is changed.
Change the uid and lter at the
intervals listed inAdditional
Required Services on page 6-6, and
be sure to use the transmission
uid listed inRecommended Fluids
and Lubricants on page 6-12.
How to Check Automatic
Transmission Fluid
Because this operation can be a
little difficult, you may choose
to have this done at the
dealer/retailer service department.
If adding it yourself, be sure to follow
all the instructions here, or there
could be a false reading on the
dipstick.Notice:Too much or too little
uid can damage your
transmission. Too much can
mean that some of the uid could
come out and fall on hot engine
parts or exhaust system parts,
starting a re. Too little uid
could cause the transmission to
overheat. Be sure to get an
accurate reading if you check
your transmission uid.
Wait at least 30 minutes before
checking the transmission uid level
if you have been driving:
When outside temperatures are
above 90°F (32°C).
At high speed for quite a while.
In heavy traffic — especially
in hot weather.
While pulling a trailer.
To get the right reading, the uid
should be at normal operating
temperature, which is 180°F to
200°F (82°C to 93°C).Get the vehicle warmed up by
driving about 15 miles (24 km) when
outside temperatures are above
50°F (10°C). If it is colder than
50°F (10°C), drive the vehicle
in 3 (Third) until the engine
temperature gage moves and then
remains steady for 10 minutes.
A cold uid check can be made after
the vehicle has been sitting for
eight hours or more with the engine
off, but this is used only as a
reference. Let the engine run at
idle for ve minutes if outside
temperatures are 50°F (10°C) or
more. If it is colder than 50°F (10°C),
the engine might have to idle
longer. Should the uid level
be low during this cold check,
check the uid hot before adding
uid. Checking the uid hot gives
a more accurate reading of the
uid level.
5-18 Service and Appearance Care

Checking the Fluid Level
To prepare the vehicle:
1. Park the vehicle on a level place.
Keep the engine running.
2. With the parking brake applied,
place the shift lever in P (Park).
3. With your foot on the brake
pedal, move the shift lever
through each gear range,
pausing for about three seconds
in each range. Then, position
the shift lever in P (Park).
4. Let the engine run at idle for
three minutes or more.
Then, without shutting off the
engine:
1. Flip the handle up and then pull
out the dipstick and wipe it with
a clean rag or paper towel.The automatic transmission
dipstick handle with this symbol
on it is located in the engine
compartment on the passenger
side of the vehicle.
SeeEngine Compartment
Overview on page 5-10for more
information on location.
2. Push it back in all the way, wait
three seconds, and pull it back
out again.
3. Check both sides of the dipstick,
and read the lower level.
The uid level must be in
the COLD area, below thecross-hatched area, for a
cold check or in the HOT or
cross-hatched area for a
hot check. Be sure to keep the
dipstick pointed down to get
an accurate reading.
4. If the uid level is in the
acceptable range, push
the dipstick back in all the way;
then ip the handle down to
lock the dipstick in place.
How to Add Automatic
Transmission Fluid
Refer to the Maintenance
Schedule to determine what kind
of transmission uid to use.
SeeRecommended Fluids and
Lubricants on page 6-12.
Add uid only after checking the
transmission uid while it is hot.
A cold check is used only as
a reference. If the uid level is low,
add only enough of the proper
uid to bring the level up to the
HOT area for a hot check.
Service and Appearance Care 5-19

It does not take much uid,
generally less than one pint (0.5 L).
Do not overll.
Notice:Use of the incorrect
automatic transmission uid may
damage the vehicle, and the
damages may not be covered
by the vehicle’s warranty. Always
use the automatic transmission
uid listed inRecommended
Fluids and Lubricants on
page 6-12.
After adding uid, recheck the
uid level as described under
“How to Check Automatic
Transmission Fluid,” earlier
in this section.
When the correct uid level is
obtained, push the dipstick
back in all the way; then ip
the handle down to lock
the dipstick in place.
Manual Transmission
Fluid
When to Check
A good time to check the manual
transmission uid is when the
engine oil is changed. However,
the uid in the manual transmission
does not require changing.
How to Check
Because this operation can be a
little difficult, you may choose
to have this done at your GM
dealer/retailer service department.
If doing it yourself, be sure to follow
all the instructions here, or there
could be a false reading.Notice:Too much or too little
uid can damage your
transmission. Too little uid
could cause the transmission to
overheat. Be sure to get an
accurate reading if you check
your transmission uid.
To check the uid:
1. Park the vehicle on a level
surface, then shut the engine off.
Let the vehicle sit until the
transmission case is cool enough
to touch.
2. Remove the ller plug.
