window GMC SIERRA DENALI 2010 Owner's Manual

.To carry long items, move the crossrails as far
apart as possible. Tie the load to the crossrails and
the siderails or siderail supports. Also tie the load
to the bumpers, but do not tie the load so tightly
that the crossrails or siderails are damaged.
.After moving a crossrail, be sure it is securely
locked into the siderail.
A Center High-Mounted Stoplamp (CHMSL) is located
above the rear window glass.
Make sure items loaded on the roof of the vehicle do
not block or damage the CHMSL.
Rear Seat Armrest
Vehicles with a rear seat armrest have two cupholders.
Pull the armrest down from the rear seatback to access
the cupholders.
Cargo Management System
For vehicles with a cargo management system, it is
located in the bed of the truck. The system contains
three rails located on the front and sides of the bed.
The system has four adjustable cargo tie-downs, that
can be placed on the upper and lower slides of the rail.
To adjust a tie-down, pull the locator pin out and move
the tie-down to another location making sure the locator
pin lines up with a locator hole on the rail. The tie-down
pin may not be installed correctly if the pin does not line
up, turn it over and reinstall. The tie-down will not move
when the pin is completely installed. The maximum load
for each rail is 500 lbs (227 kg).
The rails are notched at each end which allows the
tie-downs to be removed and placed on another rail. To
remove, pull the locator pin out and slide the tie-down to
the end of the rail and pull back.

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.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator's output
and the vehicle's electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER
ACTIVE, BATTERY VOLTAGE LOW, or LOW
BATTERY. If this message is displayed, it is
recommended that the driver reduce the electrical loads
as much as possible. See
DIC Warnings and Messages
on page 4‑57.
Battery Run-Down Protection
This feature shuts off the dome and reading lamps,
if they are left on for more than 10 minutes after the
ignition is turned off. The cargo lamp shuts off after
20 minutes. This prevents the battery from
running down.

Ashtray(s) and Cigarette Lighter
The vehicle may have a front ashtray located near the
center of the instrument panel. Pull on the door to open
it. The ashtray may have a cigarette lighter.
Notice:If papers, pins, or other flammable items are
put in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
the vehicle. Never put flammable items in the
ashtray.
To remove the ashtray, open the door and pull the
ashtray bin toward you. To replace the ashtray, insert
the ashtray bin inside the ashtray door and press down
until it engages. To use the cigarette lighter, push it in
all the way, and let go. When it is ready for use, the
lighter pops back out.
Notice: Holding a cigarette lighter in while it is
heating does not let the lighter back away from the
heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.

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 or passenger 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 cover the solar sensor located on the top of the
instrument panel near the windshield. This sensor
regulates air temperature based on sun load. For more
information on the solar sensor, see “Sensors”later in
this section.
To avoid blowing cold air in cold weather, the system
delays turning the fan on until warm air is available. The
length of delay depends on the engine coolant
temperature. Pressing the fan switch overrides this
delay and changes the fan to a selected speed.Manual Operation
D C(Fan Control): Press these buttons to increase or
decrease the fan speed.
Pressing either fan button while in automatic control
places the fan under manual control. The fan setting
remains displayed and the AUTO light turns off. The air
delivery mode remains under automatic control.
H G(Air Delivery Mode Control): Press these buttons
to change the direction of the airflow in the vehicle.
Repeatedly press either button until the desired mode
appears on the display. Pressing either mode button
while the system is off changes the air delivery mode
without turning the system on. Pressing either mode

6(Floor):Air is directed to the floor outlets, with some
to the windshield, side window outlets, and second row
floor outlets. In this mode, the system automatically
selects outside air.
-(Defog): This mode clears the windows of fog or
moisture. Air is directed to the windshield, floor outlets,
and side window vents. In this mode, the system turns
off recirculation and runs the air conditioning
compressor unless the outside temperature is close to
freezing. The recirculation mode cannot be selected
while in the defrost mode.
0(Defrost): This mode removes fog or frost from the
windshield more quickly. Air is directed to the
windshield and side window vents, with some directed
to the floor vents. In this mode, the system
automatically forces outside air into the vehicle and
runs the air conditioning compressor unless the outside
temperature is close to freezing. The recirculation mode
cannot be selected while in the defrost mode.
The passenger temperature control cannot be activated
while in defrost mode. If the PASS button is pressed,
the button indicator flashes three times and will not
work. If the passenger temperature buttons are
adjusted, the driver temperature indicator changes. The
passenger temperature will not be displayed. If vent, bi-level, or floor mode is selected again, the
climate control system displays the previous
temperature settings.
Do not drive the vehicle until all the windows are clear.
#(Air Conditioning):
Press to turn the air
conditioning (A/C) compressor on and off. An indicator
light comes on to show that the air conditioning is on.
If this button is pressed when the air conditioning
compressor is unavailable due to outside conditions, the
indicator flashes three times and then turns off. If the air
conditioning is on and the outside temperature drops
below a temperature which is too cool for air
conditioning to be effective, the air conditioning light
turns off to show that the air conditioning mode has
been canceled.
On hot days, open the windows long enough to let hot
inside air escape. This helps to reduce the time it takes
for the vehicle to cool down. It also helps the system to
operate more efficiently.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine. This
is normal.
