ESP GMC YUKON XL 2007 Owners Manual

Memory Seat, Mirrors, and Pedals
Your vehicle may have the memory package.
The controls for this
feature are located on
the driver’s door
panel, and are used to
program and recall
memory settings for the
driver’s seat, outside
mirrors, and the
adjustable throttle and
brake pedal feature
if your vehicle has it.
To save your positions in memory, do the following:
1. Adjust the driver’s seat, including the
seatback recliner and lumbar, both outside
mirrors, and the throttle and brake pedals to a
comfortable position.
SeeOutside Power Mirrors on page 164and
Adjustable Throttle and Brake Pedal on
page 140for more information.
Some mirrors might not function with the
memory feature.2. Press and hold button 1 until two beeps
sound through the driver’s front speaker
to let you know that the position has been
stored.
A second seating, mirror, and throttle and brake
pedal position can be programmed by repeating
the above steps and pressing button 2.
To recall the memory positions, the vehicle must
be in PARK (P). Press and release either button 1
or button 2 corresponding to the desired driving
position. The seat, outside mirrors, and adjustable
throttle and brake pedals will move to the position
previously stored. You will hear a single beep.
If you use the remote keyless entry transmitter to
enter your vehicle and the remote recall memory
feature is on, automatic seat, mirror, and
adjustable pedal movement will occur. See
“MEMORY SEAT RECALL” underDIC Vehicle
Customization (With DIC Buttons) on page 264
for more information.
To stop recall movement of the memory feature at
any time, press one of the power seat controls,
memory buttons, power mirror buttons, or
adjustable pedal switch.

or the safety belts!
With safety belts, you slow down as the vehicle
does. You get more time to stop. You stop
over more distance, and your strongest bones
take the forces. That is why safety belts
make such good sense.
Questions and Answers About
Safety Belts
Q:Will I be trapped in the vehicle after an
accident if I am wearing a safety belt?
A:Youcouldbe — whether you are wearing a
safety belt or not. But you can unbuckle a
safety belt, even if you are upside down. And
your chance of being conscious during and
after an accident, so youcanunbuckle and get
out, ismuchgreater if you are belted.
Q:If my vehicle has airbags, why should I
have to wear safety belts?
A:Airbags are in many vehicles today and will be
in most of them in the future. But they are
supplemental systems only; so they workwith
safety belts — not instead of them. Every
airbag system ever offered for sale has
required the use of safety belts. Even if you
are in a vehicle that has airbags, you still have
to buckle up to get the most protection. That
is true not only in frontal collisions, but
especially in side and other collisions.
42

The frontal airbags (driver and right front
passenger) are not intended to inate during
vehicle rollovers, rear impacts, or in many side
impacts.
Your vehicle has a seat position sensor which
enables the sensing system to monitor the
fore and aft position of the driver’s seat. Seat
position sensors provide information that is used
to determine if the airbags should deploy at a
reduced level or at full deployment.
Your vehicle may or may not have a roof-mounted
rollover airbags and a rollover sensor. SeeAirbag
System on page 90. These “rollover capable”
airbags are intended to inate in moderate to
severe side crashes, during a rollover or in a severe
frontal impact. A roof-mounted rollover airbag will
inate if the crash severity is above the system’s
designed “threshold level.” The threshold level can
vary with specic vehicle design. Roof-mounted
airbags are not intended to inate in rear impacts.
Both roof-mounted rollover airbags will deploy when
either side of the vehicle is struck or during a
rollover, or in a severe frontal impact.In any particular crash, no one can say whether
an airbag should have inated simply because
of the damage to a vehicle or because of what the
repair costs were. For frontal airbags, ination is
determined by what the vehicle hits, the angle
of the impact, and how quickly the vehicle slows
down. For roof-mounted rollover airbags,
ination is determined by the location and severity
of the impact or a rollover event.
The airbag system is designed to work properly
under a wide range of conditions, including off-road
usage. Observe safe driving speeds, especially
on rough terrain. As always, wear your safety belt.
SeeOff-Road Driving on page 356for tips on
off-road driving.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially
children — can easily open the
doors and fall out of a moving vehicle.
When a door is locked, the handle will
not open it. You increase the chance of
being thrown out of the vehicle in a
crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A
child can be overcome by extreme heat
and can suffer permanent injuries or
even death from heat stroke. Always
lock your vehicle whenever you
leave it.
CAUTION: (Continued)
CAUTION: (Continued)

Outsiders can easily enter through an
unlocked door when you slow down
or stop your vehicle. Locking your
doors can help prevent this from
happening.
There are several ways to lock and unlock your
vehicle.
From the outside, use the remote keyless
entry (RKE) transmitter or the key in the
driver’s door.
From the inside, use the power door locks or
manual door locks. To lock or unlock the door with
the manual locks, push down or pull up on the
manual lock knob.
120

Windows
{CAUTION:
Leaving children, helpless adults, or pets
in a vehicle with the windows closed is
dangerous. They can be overcome by the
extreme heat and suffer permanent
injuries or even death from heat stroke.
Never leave a child, a helpless adult, or a
pet alone in a vehicle, especially with the
windows closed in warm or hot weather.
130

Sun Visors
Pull the sun visor down to block glare. Detach the
sun visor from the center mount and slide it
along the rod from side-to-side to cover the driver
or passenger side of the front window. Swing
the sun visor to the side to cover the side window.
It can be moved along the rod from side-to-side
in this position also.
Lighted Visor Vanity Mirror
Your vehicle may have lighted visor vanity mirrors
on both the driver’s and passenger’s sun visors.
Pull the sun visor down and lift the mirror cover to
turn the lamps on.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing we
put on it can make it impossible to steal.
Content Theft-Deterrent
Your vehicle may have a content theft-deterrent
alarm system.
To activate the theft-deterrent system, do the
following:
1. Open the door.
2. Lock the door with the Remote Keyless Entry
(RKE) transmitter. The security light should
come on and ash. The door does not need to
be open.
If the delayed locking feature is active, the
alarm will not be activated until all doors are
closed and the security light goes off.
3. Close all doors. The security light will stop
ashing and go off after approximately
30 seconds. The content theft deterrent alarm
is not armed until the security light goes off.
132

This will protect the transfer case from possible
damage and will only allow the transfer case to
respond to one shift per 10 seconds. The transfer
case may stay in this mode for up to three minutes.
Parking Brake
To set the parking brake, hold the regular brake
pedal down with your right foot. Push down
the parking brake pedal with your left foot.
A chime will activate and the warning light will
ash when the parking brake is applied and
the vehicle is moving at least 3 mph (5 km/h) for
at least three seconds.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, to release the
parking brake.
If the ignition is on when the parking brake is
released, the brake system warning light will go off.
Notice:Driving with the parking brake on
can overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and are parking on any
hill, seeTowing a Trailer on page 405.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional DRL are required on all
vehicles rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on
The exterior lamps control is in AUTO
The light sensor determines it is daytime
When the DRL are on, only your DRL lamps will
be on. The taillamps, sidemarker and other
lamps will not be on. The instrument panel back
lighting will not be on either.
When it begins to get dark, the automatic
headlamp system will switch from DRL to the
headlamps.
When you turn the headlamp switch off, the
headlamps will go off, and your DRL lamps will
illuminate, provided it is not dark outside.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on the headlamps at the
normal brightness, along with the taillamps,
sidemarker, parking lamps, and the instrument
panel lights. The radio back lighting will also
be dimly lit.
To turn off the automatic headlamp system, turn
the exterior lamps switch to the off position.
Turning off the automatic headlamp system with
the headlamp switch is not available for vehicles
rst sold in Canada.
Your vehicle has a light sensor located on the
top of the instrument panel in the defroster grille
that regulates when the automatic headlamps turn
on. Be sure it is not covered, or the system will
come on whenever the ignition is on.
The system may also turn on your headlamps
when driving through a parking garage, heavy
overcast weather, or a tunnel. This is normal.
There is a delay in the transition between the
daytime and nighttime operation of the Daytime
Running Lamps (DRL) and the automatic headlamp
systems so that driving under bridges or bright
overhead street lights does not affect the system.

If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
The airbag readiness light should ash for a few
seconds when you turn the ignition key to RUN.
If the light doesn’t come on then, have it xed so it
will be ready to warn you if there is a problem.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your overhead console has a passenger airbag
status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol to let you know the status of the
right front passenger’s frontal airbag.
