2010 GMC YUKON change time

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 may 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. Headphones should be worn with
headband over the top of the head for best audio
reception. 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 the 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. See your dealer
for more information.
Battery Replacement
To change the batteries on the headphones:
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.

DVD Distortion
Video distortion can occur when operating cellular
phones, scanners, CB radios, Global Position Systems
(GPS)*, two-way radios, mobile fax, or walkie talkies.
It might be necessary to turn off the DVD player when
operating one of these devices in or near the vehicle.
*Excludes the OnStar
®System.
Cleaning the RSE Overhead Console
When cleaning the RSE overhead console surface, use
only a clean cloth dampened with clean water.
Cleaning the Video Screen
When cleaning the video screen, use only a clean cloth
dampened with clean water. Use care when directly
touching or cleaning the screen, as damage could
result.
Rear Seat Audio (RSA)
Vehicles with this feature allow the rear seat
passengers to listen to and control any of the music
sources: radio, CDs, DVDs, or other auxiliary sources.
However, the rear seat passengers can only control
the music sources the front seat passengers are not
listening to (except on some radios where dual control
is allowed). For example, rear seat passengers can
control and listen to a CD through the headphones,
while the driver listens to the radio through the front
speakers. The rear seat passengers have control of
the volume for each set of headphones.
The radio functionality is controlled by both the RSA
and the front radio. Only one band can be tuned to at
one time. Changing the band on the RSA or the front
radio will change the band on the other system, if they
are both sourced to the radio.
The RSA functions operate even when the main radio is
off. The front audio system will display the headphone
icon when the RSA is on, and will disappear from the
display when it is off.

Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing
down. If one of the wheels is about to stop rolling,
the computer will separately work the brakes at each
front wheel and at both rear wheels.
ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help the
driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the time needed to
get a foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, there will not be enough time to apply the
brakes if that vehicle suddenly slows or stops. Always
leave enough room up ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down firmly and let antilock work. The brakes might
vibrate or some noise might be heard, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more
than even the very best braking.
Brake Assist
This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle
speed in emergency driving conditions. This feature
uses the stability system hydraulic brake control module
to supplement the power brake system under conditions
where the driver has quickly and forcefully applied the
brake pedal in an attempt to quickly stop or slow down
the vehicle. The stability system hydraulic brake control
module increases brake pressure at each corner of
the vehicle until the ABS activates. Minor brake pedal
pulsations or pedal movement during this time is normal
and the driver should continue to apply the brake pedal
as the driving situation dictates The Brake Assist
feature will automatically disengage when the brake
pedal is released or brake pedal pressure is quickly
decreased.

Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, slow
down and adjust your driving to these conditions. It is
important to slow down on slippery surfaces because
stopping distance will be longer and vehicle control
more limited.
While driving on a surface with reduced traction,
try your best to avoid sudden steering, acceleration,
or braking, including reducing vehicle speed by shifting
to a lower gear. Any sudden changes could cause the
tires to slide. You may not realize the surface is slippery
until the vehicle is skidding. Learn to recognize warning
clues—such as enough water, ice, or packed snow on
the road to make a mirrored surface —and slow down
when you have any doubt.
Remember: Antilock brakes help avoid only the
braking skid.
Off-Road Driving
Vehicles with four-wheel drive can be used for off-road
driving. Vehicles without four-wheel drive and vehicles
with 20‐inch tire/wheel assemblies should not be driven
off-road except on a level, solid surface. The airbag system is designed to work properly under
a wide range of conditions, including off‐road usage.
Always wear your safety belt and observe safe driving
speeds, especially on rough terrain.
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 reflexes, 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.
Off-roading can be great fun but has some definite
hazards. The greatest of these is the terrain itself. When
off-road driving, traffic lanes are not marked, curves are
not banked, and there are no road signs. Surfaces can
be slippery, rough, uphill, or downhill.
Avoid sharp turns and abrupt maneuvers. Failure to
operate the vehicle correctly off‐road could result in loss
of vehicle control or vehicle rollover.
Off-roading involves some new skills. That is why it is
very important that you read these driving tips and
suggestions to help make off-road driving safer and
more enjoyable.

Controlling the vehicle is the key to successful off-road
driving. One of the best ways to control the vehicle is to
control the speed. At higher speeds:
.You approach things faster and have less time to
react.
.There is less time to scan the terrain for obstacles.
.The vehicle has more bounce when driving over
obstacles.
.More braking distance is needed, especially on an
unpaved surface.
{WARNING:
When you are driving off-road, bouncing and
quick changes in direction can easily throw you
out of position. This could cause you to lose
control and crash. So, whether you are driving on
or off the road, you and your passengers should
wear safety belts.
Scanning the Terrain
Off-road driving can take you over many different kinds
of terrain. Be familiar with the terrain and its many
different features.
Surface Conditions:Off-roading surfaces can be
hard-packed dirt, gravel, rocks, grass, sand, mud, snow,
or ice. Each of these surfaces affects the vehicle's
steering, acceleration, and braking in different ways.
Depending on the surface, slipping, sliding, wheel
spinning, delayed acceleration, poor traction, and
longer braking distances can occur.
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.
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?
.Will you have to stop suddenly or change direction
quickly?
When driving over obstacles or rough terrain, keep a
firm grip on the steering wheel. Ruts, troughs, or other
surface features can jerk the wheel out of your hands.

Towing a Trailer
If the vehicle has a two–mode hybrid engine, see the
Two–mode Hybrid manual for more information.
Do not tow a trailer during break‐in. SeeNew Vehicle
Break-In
on page 3‑27for more information.
{WARNING:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well —or
even at all. The driver and passengers could
be seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer for advice and information about
towing a trailer with the vehicle. Notice:
Pulling a trailer improperly can damage
the vehicle and result in costly repairs not covered
by the vehicle warranty. To pull a trailer correctly,
follow the advice in this section and see your dealer
for important information about towing a trailer with
the vehicle.
To identify the trailering capacity of the vehicle, read the
information in “Weight of the Trailer” that appears later
in this section.
Trailering is different than just driving the vehicle
by itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment,
and it has to be used properly.
The following information has many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers. So please read this section carefully
before pulling a trailer.

Manual Trailer Brake Apply
The Manual Trailer Brake Apply Lever is located on the
Trailer Brake Control Panel and is used to apply the
trailer’s electric brakes independent of the vehicle’ s
brakes. This lever is used in the Trailer Gain Adjustment
Procedure to properly adjust the power output to the
trailer brakes. Sliding the lever to the left will apply only
the trailer brakes. The power output to the trailer is
indicated in the Trailer Brake Display Page in the DIC.
If the vehicle’s service brakes are applied while using
the Manual Trailer Brake Apply Lever, the trailer output
power will be the greater of the two.
The trailer and the vehicle's brake lamps will come on
when either vehicle braking or manual trailer brakes are
applied.
Trailer Gain Adjustment Procedure
Trailer Gain should be set for a specific trailering
condition and must be adjusted any time vehicle
loading, trailer loading or road surface conditions
change.
Setting the Trailer Gain properly is needed for the
best trailer stopping performance. A trailer that is
over-gained may result in locked trailer brakes. A trailer
that is under-gained may result in not enough trailer
braking. Both of these conditions may result in poorer
stopping and stability of the vehicle and trailer. Use the following procedure to correctly adjust Trailer
Gain for each towing condition:
1. Make sure the trailer brakes are in proper working condition.
2. Connect a properly loaded trailer to the vehicle and make all necessary mechanical and electrical
connections. See Loading the Vehicle
on
page 5‑31for more information.
3. After the electrical connection is made to a trailer equipped with electric brakes:
.A TRAILER CONNECTED message will be
briefly displayed on the DIC display.
.The Trailer Brake Display Page will appear
on the DIC showing TRAILER GAIN and
TRAILER OUTPUT.
.In the Trailer Output display on the DIC,
“- - - - - -“ will disappear if there is no error
present. Connecting a trailer without electric
brakes will not clear the six dashed lines.
4. Adjust the Trailer Gain by using the gain adjustment (+ / -) buttons on the Trailer Brake
Control Panel.
