2009 GMC YUKON seat adjustment

Engaging the child restraint locking feature in the
right front seating position may affect the passenger
sensing system. SeePassenger Sensing System
on page 1-90for more information.
If the belt stops before it reaches the buckle, for
lap-shoulder belts with cinching latch plates, tilt the
latch plate and keep pulling the safety belt until
it can be buckled.3. Push the latch plate into the buckle until it clicks.
If you nd that the latch plate will not go fully into
the buckle, see if you are using the correct buckle.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough, seeSafety
Belt Extender on page 1-53.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. See
“Shoulder Belt Height Adjustment” later in this
section for instructions on use and important safety
information.
1-46

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. SeeReplacing Restraint System Parts
After a Crash on page 1-99.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide positions the belt
away from the neck and head.

2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START
for up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, do the same thing. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms
up and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.Adjustable Throttle and Brake Pedal
On vehicles with this feature, you can change the
position of the throttle and brake pedals.
No adjustment to the pedals can be made when the
vehicle is in R (Reverse) or while using the cruise control.
The switch used to adjust
the pedals is located on the
instrument panel 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.
Before you start driving, fully press the brake pedal to
conrm the adjustment is right for you. While driving,
make only small adjustments.
The vehicle may have a memory function which lets
pedal settings be saved and recalled. SeeMemory Seat,
Mirrors, and Pedals on page 1-8for more information.

pad to move the mirror to the desired direction.
3. Adjust each outside mirror to see a little of your
vehicle, and the area behind your vehicle.
4. Press either (A) or (B) again to deselect the mirror.

works with the memory seats. SeeMemory Seat,
Mirrors, and Pedals on page 1-8for more information.Manually fold the mirrors inward to prevent damage when

Outlet Adjustment
Use the air outlets located in the center and on the side
of the instrument panel to direct the airow.
Operation Tips

Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of the windows.
When you enter a vehicle in cold weather, press
the fan up button to the maximum fan level
before driving. This helps clear the intake ducts of
snow and moisture, and reduces the chance of
fogging the inside of the window.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
the vehicle.
Adding outside equipment to the front of the
vehicle, such as hood-air deectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer/retailer before
adding equipment to the outside of the vehicle.
Rear Air Conditioning and Heating
System
For vehicles with this system, the rear controls are three
knobs located in the headliner. The system can also
be controlled with the front controls.

B. Temperature Control
