2006 HUMMER H3 Owner ManualM

Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:

Ignition Positions
With the key in the ignition
switch, you can turn to
four different positions.
LOCK (A):This position locks your ignition. It also
locks your transmission on automatic transmission
vehicles. It will lock your steering wheel on manual
transmission vehicles when the key is removed. It is a
theft-deterrent feature. You will only be able to
remove your key when the ignition is turned to LOCK.
If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the shift lever
is in PARK (P).
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only
with your hand. Make sure the key is all the way in.If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.
ACC (ACCESSORY) (B):This is the position in which
you can operate your electrical accessories or items
plugged into the accessory power outlets. On automatic
transmission vehicles, this position unlocks the
ignition. On manual transmission vehicles, it unlocks the
ignition and steering wheel. Use this position if your
vehicle must be pushed or towed.
ON (C):This is the position that the switch returns to
after you start your engine and release the switch.
The switch stays in ON when the engine is running. But
even when the engine is not running, you can use
ON to operate your electrical accessories and to display
some instrument panel cluster warning and indicator
lights. The transmission is also unlocked in this position
on automatic transmission vehicles.
START (D):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch will return to ON for normal driving.
When the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the
radio or items plugged into the accessory power outlets.
A warning tone will sound if you open the driver’s
door when the ignition is in ACC or LOCK and the key
is in the ignition.
2-15

When in this mode you can also choose to lock the rear
axle, if equipped, for additional traction in extreme
off-road situations. SeeLocking Rear Axle on page 4-10.
Indicator lights in the buttons show which mode you
are in. The indicator lights will come on briey when you
turn on the ignition the mode the vehicle is in will stay
on. If the lights do not come on, you should take
your vehicle to your dealer for service. An indicator light
will ash while shifting the transfer case. It will remain
lit when the shift is complete. If for some reason
the transfer case cannot make a requested shift, it will
return to the last chosen setting.
If the SERV 4WD message stays on, you should take
your vehicle to your dealer for service. See Service 4WD
message underDIC Warnings and Messages on
page 3-44.
Shifting between Four-Wheel High and
Four-Wheel-High Lock
With the vehicle traveling less than 75 mph (120 km/h),
press and release the Four-Wheel High or
Four-Wheel-High Lock button. The indicator light will
ash while shifting. It will remain lit when the shift
is complete.
It may be necessary to drive backwards while turning
for a distance of 25 feet (7.5 m) to get the lock feature
to disengage.
Shifting into Four-Wheel Low Lock
Notice:Shifting the transmission into gear before
the indicator light stops ashing could cause
damage to the transfer case. Always wait until the
indicator light stops ashing before putting the
transmission back in gear.
To shift into Four-Wheel-Low Lock, the ignition must be
in ON and the vehicle must be stopped or moving
less than 3 mph (5 km/h) with the transmission in
NEUTRAL (N). The preferred method for shifting into
Four-Wheel Low is to have your vehicle moving
1 to 2 mph (1.6 to 3.2 km/h). Press and release the
Four-Wheel-Low Lock button. If your vehicle has
a manual transmission, the clutch pedal must be
pressed to the oor while you press the
Four-Wheel-Low Lock button, or the shift will not be
completed. You must wait for the Four-Wheel-Low Lock
indicator light to stop ashing and remain lit before

damage to the transfer case. Always wait until the
indicator light stops ashing before putting the
transmission back in gear.

deactivate and the light will turn off when the parking
brake is set and the vehicle is moving below 3 mph
(5 km/h). SeeBrake System Warning Light on
page 3-32.
2-27

To release the parking brake, hold the regular brake
pedal down. Pull the bottom edge of the lever, located
above the parking brake pedal, with the parking brake
symbol, directly rearward to release the parking brake.

Turn and Lane-Change Signals
The turn signal has one upward (for right) and
one downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is nished, the lever will automatically
return to the off position.
To signal a lane change, raise or lower the lever until
the arrow starts to ash. Hold it there until the change is
completed. The lever will return by itself when released.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
As you signal a turn or a lane change, if the arrows
ash more quickly than normal, a signal bulb may
be burned out and other drivers will not see your
vehicle’s turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when signaling
a turn, check for a burned-out bulb or a blown fuse.
For bulb replacement, seeTaillamps, Turn Signal,
Stoplamps and Back-up Lamps on page 5-50. For a
blown fuse or circuit breaker, seeFuses and Circuit
Breakers on page 5-96.
Turn Signal On Chime
If a turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each ash of the turn
signal and the message TURN SIGNAL will also appear
in the DIC. To turn the chime and message off, move
the turn signal lever to the off position.
See “TURN SIGNAL” underDIC Warnings and
Messages on page 3-44DIC Warnings and Messages
for more information.
Headlamp High/Low-Beam Changer
53(Headlamp High/Low Beam Changer):To
change the headlamps from low to high beam, push the
lever toward the instrument panel. To return to low-beam
headlamps, pull the multifunction lever toward you. Then
release it.
When the high beams are
on, this indicator light on
the instrument panel
cluster will also be on.
