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 may
also lock the steering wheel and automatic transmission.
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 may 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,
see Shifting 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.
See Jump Starting on page 6-40 for 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. See
Audio Steering Wheel Controls on page 3-115 for 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.

The exterior lamps control has four positions:
9 (Off): Turns off the automatic headlamps and
daytime running lamps (DRL). Turning the headlamp
control to the off position again will turn the automatic
headlamps or DRL back on.
For vehicles rst sold in Canada, the off position only
works when the vehicle is shifted into the P (Park)
position.
AUTO (Automatic): Automatically turns on the
headlamps at normal brightness, together with the
following:
Parking Lamps
Instrument Panel Lights
Taillamps
License Plate Lamps
; (Parking Lamps): Turns on the parking lamps
together with the following:
Instrument Panel Lights
Taillamps
License Plate Lamps 2 (Headlamps): Turns on the headlamps together
with the following lamps listed below.
Parking Lamps
Instrument Panel Lights
Taillamps
License Plate Lamps
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.
3-17
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. See DIC
Warnings and Messages on page 3-56 .
