When programming a garage door,
park outside of the garage. Park
directly in line with and facing the
garage door opener motor-head
or gate motor-head. Be sure that
people and objects are clear of the
garage door or gate that is being
programmed.
It is recommended that a new
battery be installed in your
hand-held transmitter for quicker
and more accurate transmission
of the radio-frequency signal.
Programming the Universal
Home Remote System
For questions or help programming
the Universal Home Remote
System, call 1‐800‐355‐3515
or go to www.homelink.com.Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.
To program up to three devices:
1. From inside the vehicle,
press and hold down the two
outside buttons at the same
time, releasing only when
the Universal Home Remote indicator light begins to flash,
after 20 seconds. This step will
erase the factory settings or all
previously programmed buttons.
Do not hold down the buttons for
longer than 30 seconds and do
not repeat this step to program
the remaining two Universal
Home Remote buttons.
2. Hold the end of your hand-held transmitter about 3 to 8 cm
(1 to 3 inches) away from the
Universal Home Remote buttons
while keeping the indicator
light in view. The hand-held
transmitter was supplied by the
manufacturer of your garage
door opener receiver (motor
head unit).

8. Immediately return to thevehicle. Firmly press and hold
the Universal Home Remote
button, selected in Step 3 to
control the garage door, for
two seconds, and then release
it. If the garage door does
not move, press and hold the
same button a second time
for two seconds, and then
release it. Again, if the door
does not move, press and hold
the same button a third time for
two seconds, and then release.
The Universal Home Remote
should now activate the
garage door. To program the remaining two
Universal Home Remote buttons,
begin with Step 2 of
“Programming
the Universal Home Remote
System.” Do not repeat Step 1,
as this will erase all previous
programming from the Universal
Home Remote buttons.
Gate Operator and Canadian
Programming
If you have questions or need
help programming the Universal
Home Remote System, call
1-800-355-3515 or go to
www.homelink.com.
Canadian radio-frequency laws
require transmitter signals to time
out or quit after several seconds
of transmission. This may not be
long enough for Universal Home
Remote to pick up the signal during
programming. Similarly, some U.S.
gate operators are manufactured to
time out in the same manner. If you live in Canada, or you are
having difficulty programming a
gate operator or garage door
opener by using the
“Programming
Universal Home Remote”
procedures, regardless of where
you live, replace Step 3 under
“Programming Universal Home
Remote” with the following:
Continue to press and hold the
Universal Home Remote button
while you press and release
every two seconds (cycle) the
hand-held transmitter button
until the frequency signal has
been successfully accepted
by the Universal Home Remote.
The Universal Home Remote
indicator light will flash slowly
at first and then rapidly. Proceed
with Step 4 under “Programming
Universal Home Remote” to
complete the training procedure.

9-8 Driving and Operating
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy, find
a safe place to park the vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving—scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will
have to do all the work of slowing
down and they could get so hot

9-12 Driving and Operating
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
or stability system. Shift back and
forth between R (Reverse) and a
forward gear, spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that
could free the vehicle. If that
does not get the vehicle out after
a few tries, it might need to be
towed out. If the vehicle does
need to be towed out, seeTowing
the Vehicle on page 10‑87.
Vehicle Load Limits
It is very important to know
how much weight your vehicle
can carry. This weight is called
the vehicle capacity weight
and includes the weight of
all occupants, cargo, and all
nonfactory-installed options.
Two labels on your vehicle
show how much weight it may
properly carry, the Tire and
Loading Information label and
the Certification/Tire label.{WARNING
Do not load the vehicle
any heavier than the
Gross Vehicle Weight
Rating (GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
shorten the life of the vehicle.

Black plate (18,1)GMC Acadia/Acadia Denali Owner Manual - 2011
9-18 Driving and Operating
Ignition Positions
The ignition switch has four different
positions.
In order to shift out of P (Park),
the ignition must be in ON/RUN or
ACC/ACCESSORY and the brake
pedal must be applied.Notice:
Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer.
((STOPPING THE ENGINE/
LOCK/OFF): When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) on
page 9‑21.
This position locks the ignition
and transmission. The key can
be removed in LOCK/OFF.
Do not turn the engine off when the
vehicle is moving. This will cause
a loss of power assist in the brake
and steering systems and disable
the airbags. In an emergency:
1. Brake using a firm and steady
pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the
shift lever must be in P (Park) to
turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on
page 9‑30.

Black plate (19,1)GMC Acadia/Acadia Denali Owner Manual - 2011
Driving and Operating 9-19
The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from right to left while turning the
key to ACC/ACCESSORY. If this
doesn't work, then the vehicle
needs service.
ACC (ACC/ACCESSORY):This
is the position in which you can
operate the electrical accessories
or items plugged into the accessory
power outlets. This position unlocks
the ignition and steering wheel. Use
this position if the vehicle must be
pushed or towed.
R(ON/RUN): This position can
be used to operate the electrical
accessories and to display some
instrument panel warning and
indicator lights. The switch stays
in this position when the engine
is running. The transmission is
also unlocked in this position. If you leave the key in the
ACC/ACCESSORY or ON/RUN
position with the engine off, the
battery could be drained. You may
not be able to start the vehicle if
the battery is allowed to drain for
an extended period of time.
/(START):
This is the position
that starts the engine. When the
engine starts, release the key.
The ignition switch will return to
ON/RUN for driving.
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
Notice: Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped. Starting Procedure
1. With your foot off the accelerator
pedal, turn the ignition to START.
When the engine starts, let go
of the key. The idle speed
will slow down as the engine
warms. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently to allow
the oil to warm up and lubricate
all moving parts.
The vehicle has a
Computer-Controlled
Cranking System. This feature
assists in starting the engine
and protects components.
If the ignition key is turned to
the START position, and then
released when the engine
begins cranking, the engine
will continue cranking for a few
seconds or until the vehicle
starts. If the engine does not
start and the key is held in
START, cranking will be stopped
after 15 seconds to prevent
cranking motor damage.

Black plate (20,1)GMC Acadia/Acadia Denali Owner Manual - 2011
9-20 Driving and Operating
To prevent gear damage, this
system also prevents cranking
if the engine is already running.
Engine cranking can be stopped
by turning the ignition switch
to the ACC/ACCESSORY or
LOCK/OFF position.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
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 flooded with
too much gasoline. Try pushing
the accelerator pedal all the
way to the floor 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
briefly but then stops again,
repeat these steps. 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. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.Engine Heater
The engine coolant heater
can provide easier starting
and better fuel economy during
engine warm-up in cold weather
conditions at or below 0°F (−18°C).
Vehicles with an engine coolant
heater should be plugged in at
least four hours before starting.
Some models may have an internal
thermostat in the cord which will
prevent engine coolant heater
operation at temperatures above
0°F (−18°C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The cord is
located on the driver side of the
engine compartment. It is routed
around the windshield washer
fluid reservoir.
3. Plug the cord into a normal, grounded 110-volt AC outlet.

Black plate (22,1)GMC Acadia/Acadia Denali Owner Manual - 2011
9-22 Driving and Operating
2. Move the shift lever into P (Park)by holding in the button on the
shift lever and pushing the shift
lever all the way toward the front
of the vehicle.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can leave the vehicle
with the ignition key in your
hand, the vehicle is in P (Park).
Leaving the Vehicle with the
Engine Running
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set. And, if you leave the
(Continued)
WARNING (Continued)
vehicle with the engine running,
it could overheat and even catch
fire. You or others could be
injured. Do not leave the vehicle
with the engine running.
If you have to leave the vehicle
with the engine running, be sure
the vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved
the shift lever into P (Park), hold
the regular brake pedal down.
Then, see if you can move the
shift lever away from P (Park)
without first pushing the button.
If you can, it means that the shift
lever was not fully locked in
P (Park).
Torque Lock
Torque lock is when the weight
of the vehicle puts too much
force on the parking pawl in the
transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not
done properly and then it is difficult
to shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see “Shifting Into Park”
listed previously.
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).
