seats GMC YUKON DENALI 2010 Owner's Manual

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger positions.
Adjust the height so that the shoulder portion of the belt
is centered on the shoulder. The belt should be away
from the face and neck, but not falling off the shoulder.
Improper shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
Squeeze the buttons (A)
on the sides of the height
adjuster and move the
height adjuster to the
desired position.
The adjuster can be moved up just by pushing up on
the shoulder belt guide.
After the adjuster is set to the desired position, try to
move it down without squeezing the buttons to make
sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt pretensioners for front
outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the
safety belt assembly. They can help tighten the safety
belts during the early stages of a moderate to severe
frontal, near frontal, or rear crash if the threshold
conditions for pretensioner activation are met. And,
if the vehicle has side impact airbags, safety belt
pretensioners can help tighten the safety belts in a
side crash or a rollover event.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle's safety belt
system. See Replacing Restraint System Parts After a
Crash on page 2‑94.
Rear Safety Belt Comfort Guides
This vehicle may have rear shoulder belt comfort
guides. If not, they are available through your dealer/
retailer. The guides may provide added safety belt
comfort for older children who have outgrown booster
seats and for some adults. When installed and properly
adjusted, the comfort guide positions the belt away from
the neck and head.
2-43

To make the belt shorter, pull its free end as shown until
the belt is snug.
If the belt is not long enough, seeSafety Belt Extender
on page 2‑48.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the safety
belt quickly if necessary.
If you find that the latch plate will not go fully into the
buckle, see if you are using the correct buckle. Be sure
that the latch plate clicks when inserted into the buckle.
Safety Belt Extender
If the vehicle's safety belt will fasten around you, you
should use it.
But if a safety belt is not long enough, your dealer/
retailer will order you an extender. When you go in to
order it, take the heaviest coat you will wear, so the
extender will be long enough for you. To help avoid
personal injury, do not let someone else use it, and use
it only for the seat it is made to fit. The extender has
been designed for adults. Never use it for securing child
seats. To wear it, attach it to the regular safety belt. For
more information, see the instruction sheet that comes
with the extender.

Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.The manufacturer's instructions that come with the
booster seat, state the weight and height limitations for
that booster. Use a booster seat with a lap-shoulder belt
until the child passes the below fit test:
.Sit all the way back on the seat. Do the knees
bend at the seat edge? If yes, continue. If no,
return to the booster seat.
.Buckle the lap-shoulder belt. Does the shoulder
belt rest on the shoulder? If yes, continue. If no, try
using the rear safety belt comfort guide. See
“Rear
Safety Belt Comfort Guides” underLap-Shoulder
Belt
on page 2‑40for more information. If the
shoulder belt still does not rest on the shoulder,
then return to the booster seat.
.Does the lap belt fit low and snug on the hips,
touching the thighs? If yes, continue. If no, return
to the booster seat.
.Can proper safety belt fit be maintained for length
of trip? If yes, continue. If no, return to the
booster seat.
If you have the choice, a child should sit in a position
with a lap-shoulder belt and get the additional restraint
a shoulder belt can provide.

Securing an Add-On Child Restraint in
the Vehicle
{WARNING:
A child can be seriously injured or killed in a crash
if the child restraint is not properly secured in the
vehicle. Secure the child restraint properly in the
vehicle using the vehicle's safety belt or LATCH
system, following the instructions that came with
that child restraint and the instructions in this
manual.
To help reduce the chance of injury, the child restraint
must be secured in the vehicle. Child restraint systems
must be secured in vehicle seats by lap belts or the lap
belt portion of a lap-shoulder belt, or by the LATCH
system. See Lower Anchors and Tethers for Children
(LATCH)
on page 2‑59for more information. A child
can be endangered in a crash if the child restraint is
not properly secured in the vehicle. When securing an add-on child restraint, refer to the
instructions that come with the restraint which may be
on the restraint itself or in a booklet, or both, and to this
manual. The child restraint instructions are important,
so if they are not available, obtain a replacement copy
from the manufacturer.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and injure
people in the vehicle. Be sure to properly secure any
child restraint in the vehicle
—even when no child
is in it.
Securing the Child Within the Child
Restraint
{WARNING:
A child can be seriously injured or killed in a crash
if the child is not properly secured in the child
restraint. Secure the child properly following the
instructions that came with that child restraint.

Third Row—Three
Passenger
i(Top Tether Anchor):
Seating positions with top
tether anchors. There is
one top tether anchor that
can be used for either the
third row center or driver
side seating position but
not both at the same time.
For models with a three passenger third row seat, see
the information following for installing a child restraint
with a top tether in the third row, if your vehicle has one.
Never install two top tethers using the same top tether
anchor.
For models with 60/40 second row seating, the rear
right side passenger and center seating positions have
exposed metal anchors located in the crease between
the seatback and the seat cushion.
For models with second row bucket seats, both rear
seating positions have exposed metal anchors located
in the crease between the seatback and the seat
cushion.
Second Row Seat —Bucket
For models with bucket second row seating, the top
tether anchors are located at the bottom rear of the seat
cushion for each seating position in the second row. Be
sure to use an anchor located on the same side of the
vehicle as the seating position where the child restraint
will be placed.

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/retailer and the service
manual have information about servicing the vehicle
and the airbag system. To purchase a service manual,
seeService 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.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q: Is there anything I might add to or change about the vehicle that could keep the airbags from
working properly?
A: Yes. If you add things that change the vehicle's
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts of
the front seats, safety belts, the airbag sensing and
diagnostic module, steering wheel, instrument panel,
roof-rail airbag modules, ceiling headliner or pillar
garnish trim, overhead console, front sensors, side
impact sensors, rollover sensor module, or airbag
wiring can affect the operation of the airbag system.
In addition, the vehicle may have a passenger
sensing system for the right front passenger
position, which includes sensors that are part of the
passenger seat. The passenger sensing system
may not operate properly if the original seat trim is
replaced with non-GM covers, upholstery or trim,
or with GM covers, upholstery or trim designed for a

Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine from outside
of the vehicle. It may also start up the vehicle's heating
or air conditioning systems and rear window defogger.
Normal operation of the system will return after the key
is turned to the ON/RUN position.
If your vehicle has an automatic climate control system,
the climate control system will default to a heating or
cooling mode depending on the outside temperatures.
If your vehicle does not have an automatic climate
control system, the system will turn on at the setting the
vehicle was set to when the vehicle was last turned off.
During a remote start, if your vehicle has an automatic
climate control system and heated seats, the heated
seats will turn on during colder outside temperatures
and will shut off when the key is turned to ON/RUN.
If your vehicle does not have an automatic climate
control system, during remote start, you will need to
manually turn the heated seats on and off. SeeHeated
and Cooled Seats
on page 2‑5for additional
information.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require
a person using the remote start to have the vehicle in
view when doing so. Check local regulations for any
requirements on remote starting of vehicles. Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
If your vehicle has the remote start feature, the RKE
transmitter functions will have an increased range of
operation. However, the range may be less while the
vehicle is running.
There are other conditions which can affect the
performance of the transmitter, see
Remote Keyless
Entry (RKE) System
on page 3‑4for additional
information.
/ (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.

Center Console Storage
A console compartment is located between the bucket
seats.
Press the button on the front of the console and swing
the console cover to open it.
An accessory power outlet may be located inside the
console. SeeAccessory Power Outlet(s) on page 4‑16.
The rear of the console also has a cupholder that
swings down for the rear seat passengers.
Roof Rack System
{WARNING:
If something is carried on top of the vehicle that is
longer or wider than the roof rack— like paneling,
plywood, or a mattress— the wind can catch it
while the vehicle is being driven. The item being
carried could be violently torn off, and this could
cause a collision, and damage the vehicle. Never
carry something longer or wider than the roof rack
on top of the vehicle unless using a GM Certified
accessory carrier. For vehicles with a roof rack, the rack can be used to
load items. For roof racks that do not have crossrails
included, GM Certified crossrails can be purchased as
an accessory. See your dealer/retailer for additional
information.
Notice:
Loading cargo on the roof rack that weighs
more than 91 kg (200 lbs) or hangs over the rear or
sides of the vehicle may damage the vehicle. Load
cargo so that it rests evenly between the crossrails,
making sure to fasten cargo securely.
To prevent damage or loss of cargo when driving,
check to make sure crossrails and cargo are securely
fastened. Loading cargo on the roof rack will make the
vehicle’s center of gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may result in loss of control.
If driving for a long distance, on rough roads, or at high
speeds, occasionally stop the vehicle to make sure the
cargo remains in its place.

Entry Lighting
The vehicle has an illuminated entry feature.
When the doors are opened, the dome lamps will
come on if the dome override button is in the extended
position. If the dome override button is pressed in,
the lamps will not come on.
Exit Lighting
The interior lamps come on when the key is removed
from the ignition. They turn off automatically in
20 seconds. The lights do not come on if the dome
override button is pressed in.
Front Reading Lamps
The reading lamps are located on the overhead
console.
To turn the reading lamps on or off, press the button
located next to each lamp.
The lamps can be adjusted to a desired direction.
The vehicle may also have reading lamps in other
locations. To turn the lamps on or off, press the button
located next to the lamp. These lamps are fixed and
cannot be adjusted.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery's temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery's state of charge is low, the voltage is
raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at high
speed, heated seats, engine cooling fans, trailer loads,
and loads plugged into accessory power outlets.
4-15

The interior temperature sensors located in the
headliner above the driver side seat and if equipped, in
the headliner above the second row seats measure the
temperature of the air inside the vehicle.
There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside air
temperature and helps maintain the temperature inside
the vehicle. Any cover on the front of the vehicle could
cause a false reading in the displayed temperature.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the air
delivery mode. The system may also supply cooler air
to the side of the vehicle facing the sun. The
recirculation mode will also be used as needed to
maintain cool outlet temperatures.
Outlet Adjustment
Use the air outlets located in the center and on the side
of the instrument panel to direct the airflow. Use the
thumbwheels near the air outlets to open or close off
the airflow.
Operation Tips
.Clear away any ice, snow, or leaves from air inlets
at the base of the windshield that could block the
flow of air into the vehicle.
.Keep the path under the front seats clear of
objects to help circulate the air inside of the
vehicle more effectively.
.Use of non‐GM approved hood deflectors can
adversely affect the performance of the system.
Check with your dealer/retailer before adding
equipment to the outside of the vehicle.
