GMC YUKON XL 2007 Owners Manual

Power Windows
The power window controls are located on each of
the side doors.
The driver’s door has a switch for the passenger
and rear windows also. The power windows
work when the ignition has been turned to
ACCESSORY or RUN or when Retained
Accessory Power (RAP) is active. See
Retained Accessory Power (RAP) on
page 138.
Press the switch to lower the window.
Pull up on the front edge of the switch to raise the
window.
Express-Down Windows
The driver and front passenger windows have an
express-down feature that allows the windows
to be lowered without holding the switch. Press
down fully on the window switch, then release,
to activate the express-down mode. The
express-down mode can be canceled at any
time by pulling up on the switch.
Window Lockout
o
(Window Lockout):The window lockout
switch is located with the power window switches
on the driver’s door armrest. This feature
prevents the passenger windows from operating,
except from the driver’s position. Press the
switch to turn on the lockout feature. An indicator
light will come on to show the lockout feature
is on. To turn the feature off, press the switch
again and the indicator light will go off.
131

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

If a door is opened without using the RKE
transmitter, a ten second pre-alarm will occur.
The horn will chirp and the lights will ash. If the
key is not placed in the ignition and turned to
START or the door is not unlocked by pressing the
unlock button on the RKE transmitter during the
ten second pre-alarm, the alarm will go off.
Your vehicle’s headlamps will ash and the horn
will sound for about two minutes, then will turn
off to save the battery power.
The theft-deterrent system will not activate if you
lock the doors with a key, the manual door lock, or
the power door lock switch. It activates only if you
use the RKE transmitter. You should also
remember that you can start your vehicle with the
correct ignition key if the alarm has been set off.
Here is how to avoid setting off the alarm by
accident:
If you do not want to activate the
theft-deterrent system, the vehicle should be
locked with the door key after the doors
are closed.
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off the
alarm if the system has been armed.If you set off the alarm by accident, turn off the
alarm by pressing unlock on the RKE transmitter or
by placing the key in the ignition and turning it
to START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.
If the alarm does not sound when it should, but
the vehicle’s headlamps ash, check to see if the
horn works. The horn fuse may be blown. To
replace the fuse, seeFuses and Circuit Breakers
on page 540.
If the alarm does not sound or the vehicle’s
headlamps do not ash, see your dealer for
service.
133

PASS-Key®III+
The PASS-Key®III+ system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry
Canada.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause harmful
interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.PASS-Key
®III+ uses a radio frequency
transponder in the key that matches a decoder in
your vehicle.
PASS-Key®III+ Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent
system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not
have to do anything special to arm or disarm the
system. It works when you transition the key
to RUN, ACCESSORY or START from the
OFF position.
When the PASS-Key
®III+ system senses that
someone is using the wrong key, it prevents
the vehicle from starting. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of
electrical key codes.
If the engine does not start and the security light
on the instrument panel comes on when trying
to start the vehicle, the key may have a damaged
transponder. Turn the ignition off and try again.
134

If the engine still does not start, and the key
appears to be undamaged, try another ignition key.
At this time, you may also want to check the fuse,
seeFuses and Circuit Breakers on page 540.Ifthe
engine still does not start with the other key, your
vehicle needs service. If your vehicle does start, the
rst key may be faulty. See your dealer who can
service the PASS-Key
®III+ to have a new key
made. In an emergency, contact Roadside
Assistance.
It is possible for the PASS-Key
®III+ decoder to
“learn” the transponder value of a new or
replacement key. Up to nine additional keys may
be programmed for the vehicle. The following
procedure is for programming additional keys only.
If all the currently programmed keys are lost or
do not operate, you must see your dealer or
a locksmith who can service PASS-Key
®III+ to
have keys made and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the
system.To program the new additional key do the
following:
1. Verify that the new key has a
1stamped on it.
2. Insert the original, already programmed, key
in the ignition and start the engine. If the
engine will not start, see your dealer
for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the new key to be programmed and turn
it to the RUN position within ve seconds of
removing the original key.
5. The security light will turn off once the key
has been programmed.
6. Repeat Steps 1 through 5 if additional keys
are to be programmed.
If you are driving and the security light comes on
and stays on, you may be able to restart your
engine. Your PASS-Key
®III+ system, however,
may not be working properly and must be serviced
by your dealer.
If you lose or damage your PASS-Key
®III+ key,
see your dealer or a locksmith who can service
PASS-Key
®III+ to have a new key made.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Keep your speed at 55 mph (88 km/h)
or less for the rst 500 miles (805 km).
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles
(805 km). Do not make full-throttle starts.
Avoid downshifting to brake, or slow,
the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 405for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.
136

Ignition Positions
Use the key to turn the ignition switch to four
different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the key when the ignition
is turned to LOCK.Notice:Using a tool to force the key from
the ignition switch could cause damage
or break the key. Use the correct key and turn
the key only with your hand. Make sure the
key is all the way in. If it is, turn the steering
wheel left and right while you turn the key
hard. If none of this works, then your vehicle
needs service.
B (ACCESSORY):This position lets you use
things like the radio and the windshield wipers
when the engine is off.
Notice:Lengthy operation of features such as
the radio in the accessory ignition position
and the RUN position may drain the battery and
prevent your vehicle from starting. Do not
operate your vehicle in the accessory ignition
position for a long period of time.
C (RUN):This is the position for driving. It is the
position the switch returns to after the engine
starts, and you release the key.
D (START):This position starts the engine.
137

Retained Accessory Power (RAP)
Your vehicle has a Retained Accessory Power
(RAP) feature which will allow certain features on
your vehicle to continue to work up to 10 minutes
after the ignition key is turned to LOCK.
The radio, power windows, and if the vehicle
has these features, the sunroof and OnStar
®
System, will work when the ignition key is in
RUN or ACCESSORY. Once the key is turned
from RUN to LOCK, these features will continue
to work for up to 10 minutes or until a door is
opened.
Starting the Engine
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position — that is a safety feature.
To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if
your vehicle is moving. If you do, you could
damage the transmission. Shift to PARK (P)
only when your vehicle is stopped.1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm.
Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects the electrical
system. If the ignition key is turned to the
START position, and then released when the
engine begins cranking, the engine will continue
cranking until the vehicle starts or until it
exceeds the maximum cranking time allowed,
approximately 15 seconds to prevent cranking
motor damage. To prevent gear damage, this
system also prevents cranking if the engine is
already running. The engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can
overheat and damage the cranking motor and
drain the battery. Waiting about 15 seconds
between each try, to allow the cranking motor to
cool down, will prevent damage due to
overheating.

2. If the engine does not start within 10 seconds,
push the accelerator pedal all the way to the
oor, while you hold the ignition key in
START. When the engine starts, let go of the
key and let up on the accelerator pedal.
Wait about 15 seconds between each try.
When starting your engine in very cold weather
(below 0°F or−18°C), do this:
1. With your foot off the accelerator pedal, turn
the ignition key to START and hold it there up
to 15 seconds. When the engine starts, let
go of the key.
2. If your engine still will not start, or starts but
then stops, it could be ooded with too much
gasoline. Try pushing your accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for about
three seconds.When the engine starts, let go of the key and
accelerator. If the vehicle starts briey but then
stops again, do the same thing, but this time
keep the pedal down for ve or six seconds.
This clears the extra gasoline from the engine.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.
139

Adjustable Throttle and Brake Pedal
If your vehicle has this feature, you can change
the position of the throttle and brake pedals.
The switch used to
adjust the pedals is
located on the center
console below the
climate control system.
Press the arrow at the bottom of the switch to
move the pedals closer to your body. Press
the arrow at the top of the switch to move the
pedals away from your body.
This feature is designed for shorter drivers, since
the pedals can not move farther away from
the standard position, but can move toward the
driver for better pedal reach.No adjustment to the pedals can be made when
the vehicle is in REVERSE (R) or while using
the cruise control.
Your vehicle may have a memory function which
allows pedal settings to be saved and recalled.
SeeMemory Seat, Mirrors, and Pedals on
page 13for more information.
Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the
coolant heater is not required. Your vehicle may
also have an internal thermostat in the plug end of
the cord. This will prevent operation of the engine
coolant heater when the temperature is at or above
0°F (−18°C) as noted on the cord.
