2007 HUMMER H2 trailer

Area Displayed On Screen
The image is provided by the camera located on
the rear bumper.The camera uses a special lens. The distance of
the image that appears on the screen differs
from the actual distance. The area displayed by
the camera is limited. The camera does not display
objects which are close to either corner of the
bumper or under the bumper. The spare tire and
carrier extends rearward of the rear bumper.
The area displayed on the screen may vary
according to vehicle orientation or road conditions.
Notice:The spare tire extends farther away
from rear of the vehicle than the trailer
hitch shown on rear vision camera display.
Your spare tire could hit an object even though
there appears to be enough distance on the
display between the trailer hitch and objects
behind you causing vehicle or property
damage. Do not use this system to judge the
distance between the spare tire and objects
behind you.
The following illustration shows the eld of view
that the camera provides.

At approximately 265°F (130°C), the Driver
Information Center (DIC) will display a
TRANSMISSION HOT message and the
transmission will enter a transmission protection
mode. When the transmission enters the protection
mode, you may notice a change in the transmission
shifting patterns. The transmission will return to
normal shifting patterns when the transmission uid
temperature falls below 260°F (125°C).
If the transmission uid reaches temperatures of
approximately 275°F (135°C) or greater, the DIC
will display a TRANS HOT IDLE ENGINE warning
message and a chime will sound. Pull the vehicle
off the roadway when it is safe to do so. Set the
parking brake, place the transmission in PARK (P)
and allow the engine to idle until the transmission
temperature falls below 260°F (125°C). If the
transmission continues to operate above 265°F
(130°C), please contact your nearest dealer or the
GM Roadside Assistance Center.
SeeDriver Information Center (DIC) on page 222
for further information.Notice:If you drive your vehicle with the
transmission temperature gage above normal
operating range, you can damage the
transmission. This could lead to costly repairs
that would not be covered by your warranty.
Do not drive your vehicle while the
transmission temperature gage reading is
above normal. See your dealer for service.
The following situations can cause the
transmission to operate at higher temperatures:
Towing a trailer,
hot outside air temperatures,
hauling a large or heavy load,
low transmission uid level,
high transmission uid level,
restricted air ow to the radiator.
A temporary solution to hotter transmission
operating temperatures may be to let the
transmission cool down. If the transmission is
operated at higher temperatures on a frequent
basis, seeScheduled Maintenance on page 517
for the proper transmission maintenance intervals.

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service as
soon as possible.

Cruise Control Light
The cruise light comes
on whenever you set
your cruise control. See
“Cruise Control”
underTurn
Signal/Multifunction
Lever on page 178.
Highbeam On Light
This light comes on
when the high-beam
headlamps are in use.
SeeHeadlamp High/Low-Beam Changer on
page 179.
Tow/Haul Mode Light
This light is displayed
when the tow/haul mode
has been activated.
For more information, see “Tow/Haul Mode” under
Towing a Trailer on page 374.

TRANSMISSION HOT
Notice:If you drive your vehicle while the
transmission uid is overheating and the
transmission temperature warning is displayed
on the instrument panel cluster and/or DIC,
you can damage the transmission. This could
lead to costly repairs that would not be
covered by your warranty. Do not drive your
vehicle with overheated transmission uid
or while the transmission temperature warning
is displayed.
This message displays if the transmission uid
temperature becomes high.
When the transmission enters the protection
mode, you may notice a change in the
transmission shifting patterns. When the
transmission uid temperature returns to normal,
the display turns off and the transmission
shifting patterns return to normal.If the vehicle has the Tow/Haul mode, use this
feature if the transmission is operating at higher
temperatures and/or the following situations
exist, which can cause the transmission to operate
at higher temperatures:
Towing a trailer
Hot outside air temperatures
Hauling a large or heavy load
Over-loading
Low transmission uid level
High transmission uid level
Restricted air ow to the radiator and the
auxiliary transmission oil cooler, if your vehicle
has this feature
A temporary solution to hotter transmission
operating temperatures may be to let the
transmission cool down. If the transmission is
operated at higher temperatures on a frequent
basis, seeScheduled Maintenance on page 517
for the proper transmission maintenance intervals
for the transmission on your vehicle. Also see
Transmission Temperature Gage on page 213for
more information.

Never use the front mounted receiver to tow
a trailer.
You can use the front mounted receiver to tow
your vehicle behind another. SeeRecreational
Vehicle Towing on page 369.
Power Winch Platform
You can use the power winch platform
(if equipped) with an aftermarket winch.
Connect the winch to the platform and wiring to
the vehicle following the winch manufacturer’s
guidelines.
Notice:Do not use the winch platform to
winch at a tension of more than 9,000 lbs.
(4 082 kg). This would damage your vehicle’s
frame. This damage would not be covered
by your vehicle’s warranty.If you are using a winch to pull out another
vehicle, follow the winch manufacturer’s guidelines
and observe the following to prevent damage to
your vehicle:
If possible, have your vehicle anchored from
the opposite side of the winch to a solid,
immovable object.
If winching from the front, use both of the rear
recovery loops. If winching from the rear,
use both of the front recovery loops.
Put your transmission in NEUTRAL (N).
Use your regular brakes to hold your vehicle
in place and block the wheels to keep the
vehicle from moving.
Notice:Using a power winch with the
transmission in gear to pull out another vehicle
may damage the transmission. When operating
a power winch, always leave the transmission
in NEUTRAL (N).

Steps for Determining Correct Load Limit
1. Locate the statement “The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs” on your
vehicle’s placard.
2. Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4. The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400−750 (5 x 150) = 650 lbs).5. Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
6. If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity of your vehicle.
SeeTowing a Trailer on page 374for important
information on towing a trailer, towing safety rules
and trailering tips.
