2010 GMC YUKON DENALI air condition

United StatesCanada
The words ON and OFF, or the symbol for on and off,
will be visible during the system check. If you are using
remote start, if equipped, to start the vehicle from a
distance, you may not see the system check. When the
system check is complete, either the word ON or OFF,
or the symbol for on or off, will be visible. See
Passenger Airbag Status Indicator on page 4‑29.
The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbag, seat‐mounted side impact airbags
(if equipped) and the roof-rail airbags are not affected
by the passenger sensing system. The passenger sensing system works with sensors that
are part of the right front passenger seat and safety
belt. The sensors are designed to detect the presence
of a properly-seated occupant and determine if the right
front passenger frontal airbag should be enabled (may
inflate) or not.
According to accident statistics, children are safer when
properly secured in a rear seat in the correct child
restraint for their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing child
restraint; a child riding in a forward-facing child seat; an
older child riding in a booster seat; and children, who
are large enough, using safety belts.
A label on the sun visor says,
“Never put a rear-facing
child seat in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.

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.

R (Reverse) :Use this gear to back up.
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission, see If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑29.
N (Neutral) : In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed. Notice:
Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.
D (Drive) : This position is for normal driving. It provides
the best fuel economy for the vehicle. If you need more
power for passing, and you are:
.Going less than about 35 mph (55 km/h), push the
accelerator pedal about halfway down.
.Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
D (Drive) can be used when towing a trailer, carrying a
heavy load, driving on steep hills, or for off-road driving.
You may want to shift the transmission to a lower gear
selection if the transmission shifts too often.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
under Loss of Control on page 5‑11.
3-31

When temperatures are very cold, the Hydra-Matic®
Automatic Transmission's gear shifting may be delayed
providing more stable shifts until the engine warms up.
Shifts may be more noticeable with a cold transmission.
This difference in shifting is normal.
M (Manual Mode) :This position lets drivers select
the range of gears appropriate for current driving
conditions. See Range Selection Mode later in this
section.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck,
do not spin the tires. When stopping on a hill, use
the brakes to hold the vehicle in place.
The vehicle has a shift stabilization feature that
adjusts the transmission shifting to the current driving
conditions in order to reduce rapid upshifts and
downshifts. This shift stabilization feature is designed to
determine, before making an upshift, if the engine will
be able to maintain vehicle speed by analyzing things
such as throttle position, vehicle load, and hill grade. If the shift stabilization feature determines that a current
vehicle speed cannot be maintained, the transmission
does not upshift and instead holds the current gear.
In some cases, this may appear to be a delayed shift,
however the transmission is operating normally.
The vehicle's transmission uses adaptive shift controls.
Adaptive shift controls continually compares key shift
parameters to pre‐programmed ideal shift conditions
stored in the transmissions computer. The transmission
constantly makes adjustments to improve vehicle
performance according to the way the vehicle is being
used, such as with a heavy load. During this adaptive
shift controls process, some shifts may feel different as
the transmission determines the best settings for a
particular shift.

J. Rear Window Defogger K. Air Conditioning
L. PASS
M. Passenger Temperature Control
O(On/Off): Press to turn the climate control system
on or off. Outside air still enters the vehicle, and is
directed to the floor. This direction can be changed by
pressing the mode button. Recirculation can be
selected once you have selected vent or bi-level mode.
The temperature can also be adjusted using either
temperature button. If the air delivery mode or
temperature settings are adjusted with the system off,
the display illuminates briefly to show the settings and
then returns to off. The system can be turned back on
by pressing either
O,D,C,#, the defrost or the
AUTO button.
Driver and Passenger Side Temperature
Control
The driver and passenger side temperature buttons
are used to adjust the temperature of the air coming
through the system on the driver or passenger's side of
the vehicle. The temperature can be adjusted even if
the system is turned off. This is possible since outside
air always flows through the system as the vehicle is
moving forward unless it is set to recirculation mode.
See “Recirculation” later in this section.
4-18

Press the + or−buttons to increase or decrease the
cabin temperature. The driver side or passenger side
temperature display shows the temperature setting
decreasing or increasing.
The passenger's temperature setting can be set to
match the driver's temperature setting by pressing the
PASS button and turning off the PASS indicator. When
the passenger's temperature setting is set different than
the driver's setting, the indicator on the PASS button
illuminates and both the driver side and passenger side
temperature displays are shown.
When in defrost mode the passenger temperature
setting cannot be changed.
Automatic Operation
AUTO (Automatic) : When automatic operation is
active the system will control the inside temperature,
the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current temperature(s) and AUTO will be
lit on the display. The current delivery mode and
fan speed will also be displayed for approximately
5 seconds. When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over about
4°C (40°F). The air inlet will normally be set to
outside air. If it is hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down the vehicle. The light on the
button comes on in recirculation.
2. Set the driver's and passenger's temperature. To find your comfort setting, start with a 23°C
(74°F) temperature setting and allow about
20 minutes for the system to regulate. Use the
driver's or passenger's temperature buttons to
adjust the temperature setting as necessary. If a
temperature setting of 15°C (60°F) is chosen, the
system remains at the maximum cooling setting.
If a temperature setting of 32°C (90°F) is chosen,
the system remains at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Do not to cover the solar sensor located on the top of
the instrument panel near the windshield. This sensor
regulates air temperature based on sun load and also
turns on the headlamps. For more information on the
solar sensor, see “Sensors”later in this section.
