Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
or ACC/ACCESSORY and the regular brake pedal
must be applied.
A (LOCK/OFF):This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. The key can be removed in LOCK/OFF.
On vehicles with an automatic transmission, the shift
lever must be in P (Park) to turn the ignition switch
to LOCK/OFF.
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.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/retailer.
B (ACC/ACCESSORY):This position lets things like
the radio and the windshield wipers operate while
the engine is off. Use this position if the vehicle must be
pushed or towed.
C (ON/RUN):This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The
switch stays in this position when the engine is running.
The transmission is also unlocked in this position on
automatic transmission vehicles.
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.
D (START):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.

Retained Accessory Power (RAP)
The following vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
OnStar®System (if equipped)
Sunroof (if equipped)
These features work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from
ON/RUN to LOCK/OFF, the windows and sunroof
continue to work up to 10 minutes until any door
is opened. The radio continues to work for up to
10 minutes or until the driver door is opened.
Starting the Engine
If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
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 are 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 key to START. When the engine starts,
let go of the key. The idle speed will go down as
the engine gets warm. 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 for many seconds,
cranking will be stopped after 15 seconds to prevent
cranking motor damage. 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.

Torque Lock
If you are parking on a hill and you do not shift the
transmission into P (Park) properly, the weight of the
vehicle can put too much force on the parking pawl in the
transmission. It might be difficult to pull the shift lever out
of P (Park). This is called torque lock. To prevent torque
lock, set the parking brake and then shift into P (Park)
properly before you leave the driver seat. To nd out how,
seeShifting Into Park on page 2-36.
When you are ready to drive, move the shift lever out of
P (Park) before releasing the parking brake.
If torque lock does occur, you might need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transmission.
Then you should be able to pull the shift lever out
of P (Park).
Shifting Out of Park
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
Prevent ignition key removal unless the shift
lever is in P (Park) with the shift lever button fully
released, and
Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN or ACC/
ACCESSORY and the regular brake pedal is applied.The shift lock release is always functional except in the
case of an uncharged or low voltage (less than 9 volt)
battery.
If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting on page 6-40for more information.
To shift out of P (Park) use the following:
1. Apply the brake pedal.
2. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park):
1. Ease the pressure on the shift lever.
2. While holding down the brake pedal, press the shift
lever all the way into P (Park).
3. Move the shift lever to the desired position.
If you are still having a problem shifting, then have the
vehicle serviced soon.

OnStar®Virtual Advisor
OnStar
®Virtual Advisor is a feature of OnStar®
Hands-Free Calling that uses minutes to access
location-based weather, local traffic reports, and stock
quotes. Press the phone button and give a few
simple voice commands to browse through the various
topics. See the OnStar
®Owner’s Guide for more
information. This feature is only available in the
continental U.S.
OnStar®Steering Wheel Controls
This vehicle may have a Talk/Mute button that can be
used to interact with OnStar
®Hands-Free Calling.
SeeAudio Steering Wheel Controls on page 3-113for
more information.
On some vehicles, the mute button can be used to dial
numbers into voice mail systems, or to dial phone
extensions. See the OnStar
®Owner’s Guide for more
information.
How OnStar®Service Works
The OnStar
®system can record and transmit vehicle
information. This information is automatically sent to an
OnStar
®Call Center when the OnStar®button is pressed,
the emergency button is pressed, or if the airbags or
AACN system deploy. This information usually includes
the vehicle’s GPS location and, in the event of a crash,additional information regarding the crash that the vehicle
was involved in (e.g. the direction from which the vehicle
was hit). When the Virtual Advisor feature of OnStar
®
Hands-Free Calling is used, the vehicle also sends
OnStar®the vehicle’s GPS location so they can provide
services where it is located.
OnStar
®service cannot work unless the vehicle is in a
place where OnStar®has an agreement with a wireless
service provider for service in that area. OnStar®
service also cannot work unless the vehicle is in a place
where the wireless service provider OnStar®has hired
for that area has coverage, network capacity and
reception when the service is needed, and technology
that is compatible with the OnStar
®service. Not all
services are available everywhere, particularly in remote
or enclosed areas, or at all times.
Location information about the vehicle is only
available if the GPS satellite signals are
unobstructed and available.
The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
®
equipment to operate. There are other problems OnStar®
cannot control that may prevent OnStar®from providing
OnStar®service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.

To program up to three devices:
1. To verify that the garage door opener is a Fixed
Code unit, remove the battery cover on the hand
held transmitter supplied by the manufacturer of the
garage door opener motor. If there are a row of
dip switches similar to the graphic above, the
garage door opener is a Fixed Code unit. If you
do not see a row of dip switches, return to the
previous section for Programming Universal
Home Remote – Rolling Code.
Your hand held transmitter can have between
eight to 12 dip switches depending on the
brand of transmitter.The garage door opener receiver (motor head unit)
could also have a row of dip switches that can
be used when programming the Universal Home
Remote. If the total number of switches on the motor
head and hand held transmitter are different, or if
the dip switch settings are different, use the
dip switch settings on the motor head unit to
program the Universal Home Remote. The motor
head dip switch settings can also be used when the
original hand held transmitter is not available.

When the headlamps are turned on while the vehicle is
on, the headlamps will turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the vehicle is off, the headlamps will stay
on for 10 minutes before automatically turning off to
prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp on
position to make the headlamps stay on for an additional
10 minutes.
IntelliBeam®Intelligent High-Beam
Headlamp Control System
For vehicles with this feature, be sure to read this entire
section before using it.
IntelliBeam
®is an enhancement to the vehicle’s
headlamp system. Using a digital light sensor on the
rearview mirror, this system will turn the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam
®system turns the high-beam
headlamps on when it is dark enough, there is no other
traffic present, and the IntelliBeam
®system is enabled.
Turning On and Enabling IntelliBeam®
Press and release the IntelliBeam®button on the inside
rear view mirror. The IntelliBeam®indicator on the
mirror will turn on to let you know the system has been
turned on. Once the system has been turned on, it
will remain on each time the vehicle is started.
Additionally, the IntelliBeam
®system must be enabled.
To enable the IntelliBeam
®system, turn the exterior
lamp control to AUTO, with the turn signal/multifunction
lever in its neutral position. The High-Beam On Light
will appear on the instrument panel cluster when
the high-beams are on. SeeHighbeam On Light on
page 3-45.
Driving with IntelliBeam®
IntelliBeam®will only activate your high-beams when
driving over 20 mph (32 km/h).
The high-beam headlamps will remain on, under the
automatic control of IntelliBeam
®, until any of the
following situations occur:
The system detects an approaching vehicle’s
headlamps.
The system detects a preceding vehicle’s taillamps.
The outside light is bright enough that high-beam
headlamps are not required.
3-16

Reading Lamps
If the vehicle has reading lamps, press the button
located next to the lamp to turn it on or off.
The vehicle may also have reading lamps in other
locations. The lamps 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.
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. SeeDIC
Warnings and Messages on page 3-54.
