warning GMC YUKON XL 2010 Workshop Manual

{WARNING:
A crash severe enough to inflate the airbags may
have also damaged important functions in the
vehicle, such as the fuel system, brake and
steering systems, etc. Even if the vehicle appears
to be drivable after a moderate crash, there may
be concealed damage that could make it difficult
to safely operate the vehicle.
Use caution if you should attempt to restart the
engine after a crash has occurred.In many crashes severe enough to inflate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur
from the right front passenger airbag..Airbags are designed to inflate only once. After an
airbag inflates, you will need some new parts for
the airbag system. If you do not get them, the
airbag system will not be there to help protect
you in another crash. A new system will include
airbag modules and possibly other parts.
The service manual for your vehicle covers
the need to replace other parts.
.The vehicle has a crash sensing and diagnostic
module which records information after a crash.
See
Vehicle Data Recording and Privacy
on
page 8‑17and Event Data Recorderson
page 8‑18.
.Let only qualified technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer for service.
2-93

{WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating airbag. A child in a
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
inflates and the passenger seat is in a forward
position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though the airbag is
turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint
in a rear seat.The passenger sensing system is designed to turn off
the right front passenger frontal airbag if:
.The right front passenger seat is unoccupied.
.The system determines an infant is present in a
child restraint.
.A right front passenger takes his/her weight off of
the seat for a period of time.
.Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger frontal airbag, the off indicator will
light and stay lit to remind you that the airbag is off.
See Passenger Airbag Status Indicator on page 4‑33.
The passenger sensing system is designed to turn on
(may inflate) the right front passenger frontal airbag
anytime the system senses that a person of adult size
is sitting properly in the right front passenger seat.
When the passenger sensing system has allowed the
airbag to be enabled, the on indicator will light and stay
lit to remind you that the airbag is active.
2-95

For some children, including children in child restraints,
and for very small adults, the passenger sensing
system may or may not turn off the right front passenger
frontal airbag, depending upon the person's seating
posture and body build. Everyone in your vehicle who
has outgrown child restraints should wear a safety belt
properly—whether or not there is an airbag for that
person.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. See Airbag Readiness Light
on page 4‑32
for more information, including important safety
information.
If the On Indicator is Lit for a Child
Restraint
If a child restraint has been installed and the on
indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets, cushions, seat covers, seat heaters,
or seat massagers.
4. Reinstall the child restraint following the directions provided by the child restraint manufacturer and
refer to Securing a Child Restraint in the Right
Front Seat Position on page 2‑79.
2-96

A thick layer of additional material, such as a blanket
or cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect
how well the passenger sensing system operates.
We recommend that you not use seat covers or other
aftermarket equipment except when approved by GM
for your specific vehicle. SeeAdding Equipment to
Your Airbag-Equipped Vehicle
on page 2‑100for more
information about modifications that can affect how
the system operates.
The on indicator may be lit if an object, such as a
briefcase, handbag, grocery bag, laptop or other
electronic device, is put on an unoccupied seat.
If this is not desired remove the object from the seat.
{WARNING:
Stowing of articles under the passenger seat
or between the passenger seat cushion and
seatback may interfere with the proper operation
of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer and the service manual
have information about servicing the vehicle and the
airbag system. To purchase a service manual, see
Service Publications Ordering Information
on
page 8‑16.
{WARNING:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualified to do so.
2-99

Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. SeeAirbag Readiness Light
on page 4‑32for more information.
Notice: If an airbag covering is damaged, opened,
or broken, the airbag may not work properly. Do not
open or break the airbag coverings. If there are any
opened or broken airbag covers, have the airbag
covering and/or airbag module replaced. For the
location of the airbag modules, see What Makes an
Airbag Inflate?
on page 2‑91. See your dealer for
service.
Replacing Restraint System Parts
After a Crash
{WARNING:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.
2-102

Keys
{WARNING:
Leaving children in a vehicle with the ignition key
is dangerous for many reasons, children or others
could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function with the keys in the ignition and children
could be seriously injured or killed if caught in the
path of a closing window. Do not leave the keys in
a vehicle with children.
The key is used for the ignition and all door locks.
The key has a bar-coded key tag that the dealer or
qualified locksmith can use to make new keys. Store
this information in a safe place, not in the vehicle.

Programming Transmitters to the
Vehicle
Only RKE transmitters programmed to this vehicle will
work. If a transmitter is lost or stolen, a replacement can
be purchased and programmed through your dealer.
When the replacement transmitter is programmed to
this vehicle, all remaining transmitters must also be
reprogrammed. Any lost or stolen transmitters will no
longer work once the new transmitter is programmed.
The vehicle can have a maximum of eight transmitters
programmed to it. See“Relearn Remote Key” under
DIC Operation and Displays (With DIC Buttons)
on
page 4‑48or DIC Operation and Displays (Without DIC
Buttons)on page 4‑55for instructions on how to
program RKE transmitters to the vehicle.
Battery Replacement
Replace the battery if the REPLACE BATTERY IN
REMOTE KEY message displays in the DIC. See
“REPLACE BATTERY IN REMOTE KEY” underDIC
Warnings and Messages
on page 4‑61for additional
information.
Notice: When replacing the battery, do not touch
any of the circuitry on the transmitter. Static from
your body could damage the transmitter.
To replace the battery:
1. Separate the transmitter with a flat, thin object, such as a flat head screwdriver.
.Carefully insert the tool into the notch located
along the parting line of the transmitter.
Do not insert the tool too far. Stop as soon
as resistance is felt.
.Twist the tool until the transmitter is separated.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing down. Replace with a CR2032 or equivalent battery.
4. Snap the transmitter back together.

/(Remote Start): This button will be on the RKE
transmitter if you have remote start.
To start the vehicle using the remote start feature:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter's lock button. The vehicle's doors will lock. Immediately press
and hold the transmitter's remote start button until
the turn signal lights flash. If you cannot see the
vehicle's lights, press and hold the remote start
button for two to four seconds. Pressing the remote
start button again after the vehicle has started will
turn the engine off.
When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.
If the vehicle is left running it will automatically shut
off after 10 minutes unless a time extension has
been done.
3. If it is the first remote start since the vehicle has been driven, repeat these steps, while the engine
is still running, to extend the engine running time
by 10 minutes. Remote start can be extended
one time.
After entering the vehicle during a remote start, insert
and turn the key to RUN to drive the vehicle. To manually shut off a remote start, do any of the
following:
.Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
.Turn on the hazard warning flashers.
.Turn the ignition switch on and then off.
The vehicle can be remote started two separate times
between driving sequences. The engine will run for
10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the first 10 minute remote start time
frame, and before the engine stops.
For example, if the lock button and then the remote start
buttons are pressed again after the vehicle has been
running for five minutes, 10 minutes are added, allowing
the engine to run for 15 minutes.
The additional ten minutes are considered a second
remote vehicle start.
Once two remote starts, or a single remote start with
one time extension has been done, the vehicle must be
started with the key. After the key is removed from the
ignition, the vehicle can be remote started again.
3-9

The vehicle cannot be remote started if the key is
in the ignition, the hood is not closed, or if there is an
emission control system malfunction and the check
engine light comes on.
Also, the engine will turn off during a remote vehicle
start if the coolant temperature gets too high or if the
oil pressure gets low.
Vehicles that have the remote vehicle start feature are
shipped from the factory with the remote vehicle start
system enabled. The system may be enabled or
disabled through the DIC. See“REMOTE START”
under DIC Vehicle Customization (With DIC Buttons)
on
page 4‑72for additional information. If your vehicle
does not have DIC buttons, see your dealer to enable
or disable the remote vehicle start system.
Remote Start Ready
If your vehicle does not have the remote vehicle start
feature, it may have the remote start ready feature.
This feature allows your dealer to add the
manufacturer's remote vehicle start feature.
See your dealer if you would like to add the
manufacturer's remote vehicle start feature to
your vehicle.
Doors and Locks
Door Locks
{WARNING:
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. The chance of being thrown
out of the vehicle in a crash is increased if
the doors are not locked. So, all passengers
should wear safety belts properly and the
doors should be locked whenever the vehicle
is driven.
.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 the vehicle whenever
leaving it.
