2008 HUMMER H2 turn signal

Headphones
The RSE includes two 2-channel wireless headphones
that are dedicated to this system. Channel 1 is dedicated
to the DVD player, while Channel 2 is dedicated to RSA
selections. These headphones can be used to listen to
the radio, CDs, DVDs, MP3s, DVDAs, any auxiliary
source connected to A/V jacks, or the auxiliary input jack,
if your vehicle has this feature. The wireless headphones
have an On/Off button, channel 1/2 switch, and a volume
control.
Push the power button to turn on the headphones.
An indicator light located on the headphones comes on.
If the light comes on but, there is intermittent soundand/or static on the headphones, or if the indicator
light does not come on, the batteries might need to
be replaced. See “Battery Replacement” later in
this section for more information. Switch the headphones
to Off when not in use.
Infrared transmitters are located at the rear of
the RSE overhead console. The headphones shut off
automatically to save the battery power if the RSE system
and RSA are shut off or if the headphones are out of
range of the transmitters for more than three minutes.
If you move too far forward or step out of the vehicle,
the headphones lose the audio signal.
The headphones automatically turn off after four hours
of continuous use.
To adjust the volume on the headphones, use the
volume control located on the right side.
For optimal audio performance, the headphones must
be worn correctly. The symbol L (Left) appears on
the upper left side, above the ear pad and should be
positioned on the left ear. The symbol R (Right) appears
on the upper right side, above the ear pad and should
be positioned on the right ear.
Notice:Do not store the headphones in heat or
direct sunlight. This could damage the headphones
and repairs will not be covered by your warranty.
Storage in extreme cold can weaken the batteries.
Keep the headphones stored in a cool, dry place.

If the foam ear pads attached to the headphones
become worn or damaged, the pads can be replaced
separately from the headphone set. Refer to your
dealer/retailer for more information.
Battery Replacement
To change the batteries on the headphones, do the
following:
1. Turn the screw to loosen the battery door located
on the left side of the headphones. Slide the
battery door open.
2. Replace the two batteries in the compartment.
Make sure that they are installed correctly,
using the diagram on the inside of the battery
compartment.
3. Replace the battery door and tighten the door
screw.
If the headphones are to be stored for a long period of
time, remove the batteries and keep them in a cool,
dry place.
Audio/Video (A/V) Jacks
The A/V jacks, located on the rear of the oor console,
allow audio or video signals to be connected from
an auxiliary device such as a camcorder or a video
game unit to the RSE system. Adapter connectors
or cables (not included) might be required to connect
the auxiliary device to the A/V jacks. Refer to the
manufacturer’s instructions for proper usage.
The A/V jacks are color coded to match typical home
entertainment system equipment. The yellow jack (A)
is for the video input. The white jack (B) is for the
left audio input. The red jack (C) is for the right audio
input.
Power for auxiliary devices is not supplied by the radio
system.
3-107

To use the auxiliary inputs of the RSE system, connect
an external auxiliary device to the color-coded A/V jacks
and turn both the auxiliary device and the video screen
power on. If the video screen is in the DVD player mode,
pressing the AUX (auxiliary) button on the remote control
switches the video screen from the DVD player mode to
the auxiliary device. The radio can listen to the audio of
the connected auxiliary device by sourcing to auxiliary.
SeeRadio(s) (MP3) on page 3-75for more information.
How to Change the RSE Video Screen

Audio Output
Audio from the DVD player or auxiliary inputs can be
heard through the following possible sources:
Wireless Headphones
Vehicle Speakers
Vehicle wired headphone jacks on the rear seat
audio system, if your vehicle has this feature.
The RSE system always transmits the audio signal to
the wireless headphones, if there is audio available.
See “Headphones” earlier in this section for more
information.
The DVD player is capable of outputting audio to the
wired headphone jacks on the RSA system, if your
vehicle has this feature. The DVD player can be
selected as an audio source on the RSA system.
SeeRear Seat Audio (RSA) on page 3-114for more
information.
When a device is connected to the A/V jacks, or the
radio’s auxiliary input jack, if your vehicle has this feature,
the rear seat passengers are able to hear audio from
the auxiliary device through the wireless or wired
headphones. The front seat passengers are able to
listen to playback from this device through the vehicle
speakers by selecting AUX as the source on the radio.

Video Screen
The video screen is located in the overhead console.
To use the video screen, do the following:
1. Push the release button located on the overhead
console.
2. Move the screen to the desired position.
When the video screen is not in use, push it up into its
locked position.
If a DVD is playing and the screen is raised to its locked
position, the screen remains on. This is normal, and
the DVD continues to play through the previous audio
source. Use the remote control power button or eject the
disc to turn off the screen.
The overhead console contains the infrared transmitters
for the wireless headphones and the infrared receivers
for the remote control. They are located at the rear
of the console.
Notice:Avoid directly touching the video screen,
as damage may occur. See “Cleaning the Video
Screen” later in this section for more information.
Remote Control
To use the remote control, aim it at the transmitter
window at the rear of the RSE overhead console and
press the desired button. Direct sunlight or very bright
light could affect the ability of the RSE transmitter to
receive signals from the remote control. If the remote
control does not seem to be working, the batteries might
need to be replaced. See “Battery Replacement” later in
this section. Objects blocking the line of sight could also
affect the function of the remote control.
If a CD or DVD is in the Radio DVD slot, the remote
control power button can be used to turn on the video
screen display and start the disc. The radio can also
turn on the video screen display. SeeRadio(s) (MP3)
on page 3-75for more information.
Notice:Storing the remote control in a hot area or
in direct sunlight can damage it, and the repairs
will not be covered by your warranty. Storage
in extreme cold can weaken the batteries. Keep
the remote control stored in a cool, dry place.
If the remote control becomes lost or damaged, a
new universal remote control can be purchased. If this
happens, make sure the universal remote control uses a
code set of Toshiba
®.

Surface Obstacles:Unseen or hidden obstacles can
be hazardous. A rock, log, hole, rut, or bump can startle
you if you are not prepared for them. Often these
obstacles are hidden by grass, bushes, snow, or even
the rise and fall of the terrain itself. Here are some
things to consider:
Is the path ahead clear?
Will the surface texture change abruptly up ahead?
Does the travel take you uphill or downhill?
There is more discussion of these subjects later.
Will you have to stop suddenly or change direction
quickly?
When you drive over obstacles or rough terrain, keep
a rm grip on the steering wheel. Ruts, troughs, or other
surface features can jerk the wheel out of your hands
if you are not prepared.
When possible, it is a good practice to survey the
landscape ahead on foot prior to driving to observe
hidden obstacles.When you drive over bumps, rocks, or other obstacles,
the wheels can leave the ground. If this happens,
even with one or two wheels, you cannot control the
vehicle as well or at all.
Because you will be on an unpaved surface, it is
especially important to avoid sudden acceleration,
sudden turns, or sudden braking.
In a way, off-road driving requires a different kind of
alertness from driving on paved roads and highways.
There are no road signs, posted speed limits, or signal
lights. You have to use your own good judgment
about what is safe and what is not.
Drinking and driving can be very dangerous on any
road. And this is certainly true for off-road driving.
At the very time you need special alertness and driving
skills, your reexes, perceptions, and judgment can
be affected by even a small amount of alcohol.
You could have a serious — or even fatal — accident
if you drink and drive or ride with a driver who has
been drinking. SeeDrunk Driving on page 4-2.
4-20

Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you are turning with a trailer, make wider turns
than normal. Do this so your trailer will not strike
soft shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
The arrows on your instrument panel will ash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also ash, telling other drivers
you’re about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It is
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift down,
you might have to use your brakes so much that they
would get hot and no longer work well.
You can tow in DRIVE (D). You may want to shift the
transmission to THIRD (3) or, if necessary, a lower gear
selection if the transmission shifts too often (e.g., under
heavy loads and/or hilly conditions).
You may also want to activate the tow/haul mode if the
transmission shifts too often. See “Tow/Haul Mode”
earlier.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If you turn your
engine off immediately after towing at high altitude on
steep uphill grades, your vehicle may show signs similar
to engine overheating. To avoid this, let the engine run
while parked (preferably on level ground) with the
automatic transmission in PARK (P) for a few minutes
before turning the engine off. If you do get the overheat
warning, seeEngine Overheating on page 5-27.
