2004 HUMMER H2 2 wheel drive

Tow/Haul Mode
Your vehicle is equipped
with a tow/haul mode. The
button is located on the
instrument panel to
the right of the steering
wheel.
You can use this feature to assist when towing or
hauling a heavy load. See “Tow/Haul Mode” under
Towing a Trailer on page 4-75for more information.
All-Wheel Drive
All-wheel drive sends your engine’s driving power to all
four wheels for extra traction. To get the most
satisfaction out of all-wheel drive, you must be familiar
with its operation.
Notice:Driving on pavement in 4HI Lock or
4LO Lock for extended periods may cause
premature wear on your vehicle’s powertrain and
tires. Do not drive in 4HI Lock or 4LO Lock on
pavement for extended periods.
Transfer Case Buttons
The transfer case buttons
are located to the right of
the instrument panel
cluster. Use these switches
to shift into and out of the
different all-wheel drive
modes.
You can choose between four modes:
G(4HI):This setting is used for driving in most
street and highway situations. You can also use this
setting for light or variable off-road conditions.
H(4HI Lock):Use this mode when you need extra
traction in most off-road situations such as sand,
mud, snow or level, rocky trails.
2-25

I(4LO Lock):This mode delivers extra torque to all
four wheels and is used for extreme off-road conditions.
You might choose 4LO Lock if you are driving off-road,
deep sand, mud, or snow and climbing or descending
steep hills.
When in this mode you can also choose to lock the rear
axle for additional traction in extreme off-road situations.
SeeLocking Rear Axle on page 4-11.
Notice:Operating your vehicle in 4LO Lock above
50 mph (80 km/h) for any extended period of time
could cause damage to the transfer case. Do
not operate your vehicle in 4LO Lock above 50 mph
(80 km/h) for extended periods.
{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. SeeParking Brake on
page 2-29.N (NEUTRAL):Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page 4-65orTowing
Your Vehicle on page 4-65for more information.
Indicator lights in the buttons show which mode you are
in. The indicator lights will come on briey when you
turn on the ignition and one 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 illuminated 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 SERVICE 4WD message stays on, you should
take your vehicle to your dealer for service. See “Service
4WD message” underDriver Information Center (DIC)
on page 3-44.

{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
{CAUTION:
All-wheel drive vehicles with the transfer case
in NEUTRAL will allow the vehicle to roll, even
if your shift lever is in PARK (P). So, be sure
the transfer case is in a drive gear — not in
NEUTRAL. Always set your parking brake.Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) on page 2-30.
If you are pulling a trailer, seeTowing a Trailer on
page 4-75.

Off-Road Lamps
Notice:If you drive your vehicle through an
automatic car wash that does not have enough
clearance for any roof-mounted accessories (such
as off-road lamps or a roof basket) on your vehicle,
you can damage your vehicle. To avoid damaging
your vehicle in a car wash, remove any
roof-mounted accessories if you can, and do not
use an automatic car wash while roof-mounted
accessories are on your vehicle. SeeCleaning the
Outside of Your Vehicle on page 5-95for more
information.
The off-road lamps, if equipped, are designed to
enhance the appearance of your vehicle and to provide
auxiliary lighting when your vehicle is used off road.
The safety characteristics of these lamps are limited and
they are not intended to be used in conjunction with,
or in place of, existing vehicle lighting. The lamps are not
to be used on any public street or highway and are to
be covered when not in use. Check your state and local
laws before installing or using any auxiliary lighting.
In some states it may be necessary to remove the roof
lamps when operating the vehicle on the highway.
The button for the off-road lamps is located in the
overhead console.To use the lamps, be sure the engine is running.
Remove the covers form the lamps and press the button
to turn them on. Press the button again to turn them
off. An indicator light will glow near the button when the
lamps are on.
Notice:Turning on the off-road lamps before
removing the lamp covers could damage the
off-road lamps and the covers. Always remove the
covers before turning on the off-road lamps.
The off-road lamps will remain on even after the ignition
is turned off. The off-road lamps button must be
pressed to turn them off.
