2007 GMC YUKON XL DENALI four wheel drive

SERVICE THEFT DETERRENT SYSTEM
This message will display when there is a
problem with the theft-deterrent system. The
vehicle may or may not restart so you may want
to take the vehicle to your dealer before turning off
the engine. SeePASS-Key
®III+ Operation on
page 137for more information.
SERVICE TIRE MONITOR SYSTEM
If your vehicle has the Tire Pressure Monitor
(TPM) system, this message will display if a part
on the system is not working properly. If you
drive your vehicle while any of the four sensors
are missing or inoperable, the warning will
come on in about 20 minutes. A sensor would be
missing, for example, if you put different wheels
on your vehicle without transferring the sensors.
If the warning comes on and stays on, there
may be a problem with the TPM. See your dealer.
SERVICE TRACTION CONTROL
If your vehicle has StabiliTrak®, this message will
display when there is a problem with the traction
control system. When this message is displayed,
the system will not limit wheel spin. Adjust
your driving accordingly. See your dealer for
service. SeeStabiliTrak
®System on page 349for
more information.
STABILITRAK OFF
If your vehicle has StabiliTrak®, this message will
display when you turn off StabiliTrak®, or when
the stability control has been automatically
disabled. To limit wheel spin and realize the full
benets of the stability enhancement system, you
should normally leave StabiliTrak
®on. However,
you should turn StabiliTrak®off if your vehicle gets
stuck in sand, mud, ice, or snow and you want
to rock your vehicle to attempt to free it, or if you
are driving in extreme off-road conditions and
require more wheel spin. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 390.
To turn the StabiliTrak
®system on or off, see
StabiliTrak®System on page 349.

All-Wheel Drive (AWD) System
With this feature, engine power is sent to all
four wheels all the time.
This is like four-wheel drive, but there is no
separate lever or switch to engage or disengage
the front axle. It is fully automatic, and adjusts itself
as needed for road conditions.
Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning, you
can steer but it will take much more effort.
Steering Tips
It is important to take curves at a reasonable
speed.
A lot of the “driver lost control” accidents
mentioned on the news happen on curves.
Here is why:
Experienced driver or beginner, each of us is
subject to the same laws of physics when driving
on curves. The traction of the tires against the
road surface makes it possible for the vehicle to
change its path when you turn the front wheels. If
there is no traction, inertia will keep the vehicle
going in the same direction. If you have ever
tried to steer a vehicle on wet ice, you will
understand this.
The traction you can get in a curve depends on
the condition of your tires and the road surface, the
angle at which the curve is banked, and your
speed. While you are in a curve, speed is the
one factor you can control.

Towing
Towing Your Vehicle
Consult your dealer or a professional towing
service if you need to have your disabled vehicle
towed. SeeRoadside Assistance Program on
page 575.
If you want to tow your vehicle behind another
vehicle for recreational purposes (such as behind
a motorhome), see “Recreational Vehicle
Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your
vehicle behind another vehicle — such as behind
a motorhome. The two most common types of
recreational vehicle towing are known as “dinghy
towing” (towing your vehicle with all four wheels
on the ground) and “dolly towing” (towing
your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”).
Dinghy Towing and Dolly Towing
All-Wheel Drive Vehicles
Notice:Towing an all-wheel-drive vehicle with
all four wheels on the ground, or even with
only two of its wheels on the ground, will
damage drivetrain components. Do not tow an
all-wheel-drive vehicle if any of its wheels
will be on the ground.
Your vehicle is not designed to be towed with any
of the wheels on the ground. If your vehicle
must be towed, seeTowing Your Vehicle on
page 398.

Notice:
Using the wrong uid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in your brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 530.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound may come and go or be heard all
the time your vehicle is moving, except when you
are pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon your brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.
Some driving conditions or climates may cause
a brake squeal when the brakes are rst applied or
lightly applied. This does not mean something is
wrong with your brakes.

To avoid the possibility of the vehicles rolling,
set the parking brake rmly on both vehicles
involved in the jump start procedure. Put
the automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brake. If you have a
four-wheel-drive vehicle, be sure the transfer
case is in a drive gear, not in NEUTRAL.
Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged
into the cigarette lighter or the accessory
power outlets. Turn off the radio and all the
lamps that are not needed. This will avoid
sparks and help save both batteries. And it
could save the radio!4. Open the hood on the other vehicle and
locate the positive (+) and negative (−)
terminal locations on that vehicle.
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (−)
jump starting terminal. You should always use
these remote terminals instead of the
terminals on the battery.
The remote positive (+) terminal, if equipped, is
located under a red plastic cover at the positive
battery post. To uncover the remote positive (+)
terminal, open the red plastic cover.
The remote negative (−) terminal is a stud
located on the right front of the engine, where
the negative battery cable attaches.

Your vehicle’s TPMS can alert you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 496andTires on page 480.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
Resetting the TPMS Identication Codes
Each TPMS sensor has a unique identication
code. Any time you rotate your vehicle’s tires or
replace one or more of the TPMS sensors,
the identication codes will need to be matched
to the new tire/wheel position. The sensors
are matched to the tire/wheel positions in the
following order: driver’s side front tire, passengers
side front tire, passengers side rear tire, and
driver’s side rear tire using a TPMS diagnostic tool.
See your GM dealer for service.The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. If increasing the tire’s
air pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.
You will have two minutes to match the rst
tire/wheel position, and ve minutes overall to
match all four tire/wheel positions. If it takes longer
than two minutes, to match the rst tire and
wheel, or more than ve minutes to match all
four tire and wheel positions the matching process
stops and you will need to start over.
493

The TPMS sensor matching process is outlined
below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle information
button until the PRESS
VTO RELEARN
TIRE POSITIONS message displays.
4. Press the set/reset button. The horn will
sound twice to indicate the TPMS receiver
is ready, and the TIRE LEARNING ACTIVE
message will display.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the valve cap
stem. Activate the TPMS sensor by
increasing or decreasing the tire’s air pressure
for ve seconds, or until a horn chirp
sounds. The horn chirp, which make take up
to 30 seconds to sound, conrms that the
sensor identication code has been matched
to this tire and wheel position. To decrease
air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style
air pressure gage, or a key.7. Proceed to the passenger’s side front tire, and
repeat the procedure in Step 6.
8. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 6.
9. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 6.
10. After hearing the conrming horn chirp for the
driver’s side rear tire, the horn chirp will sound
two more times to signal the tire learning
mode is no longer active. Turn the ignition
switch to LOCK.
11. Set all four tires to the recommended air
pressure level as indicated on the Tire
and Loading Information label.
12. Put the valve caps back on the valve stems
The spare tire does not have a TPMS sensor.
If you replace one of the road tires with the spare,
the SERVICE TIRE MONITOR message will be
displayed on the DIC screen. This message should
go off once you re-install the road tire containing
the TPMS sensor.
