The passenger sensing system may not operate
properly if the original seat trim is replaced with
non-GM covers, upholstery or trim, or with GM
covers, upholstery or trim designed for a different
vehicle. Any object, such as an aftermarket seat
heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric, could also
interfere with the operation of the passenger sensing
system. This could either prevent proper deployment
of the passenger airbag(s) or prevent the passenger
sensing system from properly turning off the
passenger airbag(s). SeePassenger Sensing
System on page 1-67.

Ignition Positions
The ignition switch has
four different positions.
In order to shift out of P (Park), ignition must be in the
ON/RUN or ACC/ACCESSORY and the regular
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/retailer.
9(LOCK/OFF):This position locks the ignition and
steering column, with the key removed. You will only be
able to remove the key when the ignition is turned to
LOCK/OFF
The ignition switch cannot be turned to LOCK/OFF
unless the shift lever is in P (Park).
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 does not work, then the vehicle needs service.

Automatic Transmission Operation
(3.4L V6 with 5-Speed)
The shift lever is located on the center console. When
you change gears, the different shift positions will display
on the instrument panel cluster.
There are several different positions for the automatic
transmission.
P (Park):This position locks the front wheels. It is
the best position to use when you start the engine
because the vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
rmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park on page 2-32. If you are pulling a trailer, see
Towing a Trailer on page 4-32.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must fully
apply the brake pedal and then press the shift lever
button before you can shift from P (Park) when the
ignition key is in ON/RUN. If you cannot shift out of
P (Park), ease pressure on the shift lever and push the
shift lever all the way into P (Park) as you maintain brake
application. Then press the shift lever button and move
the shift lever into another gear. SeeShifting Out of Park
on page 2-33.
2-24
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,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-19.
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.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is rmly 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.
Notice:Shifting to a drive gear from NEUTRAL (N)
while the vehicle is moving could damage the
transmission. Make sure the vehicle is stopped
before shifting from NEUTRAL (N) into a drive gear.
D (Drive):This position is for normal driving with
the automatic transmission. It provides the best fuel
economy. 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), push the accelerator
all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-11.
2-25
Automatic Transmission Operation
(3.6L V6 with 6-Speed)
The shift lever for the automatic transmission is located
on the console between the seats.
Maximum engine speed is limited when the vehicle is in
P (Park) or N (Neutral) to protect driveline components
from improper operation.
There are several different positions for the shift lever.
When using the MSM (Manual Shift Mode), a number
indicating the gear selected will appear on the instrument
cluster below the shift position display. For more
information on the manual shift option see “Manual
Shift Mode” in this section.
P (Park):This position locks the front wheels. It is the
best position to use when the engine is started
because the vehicle cannot move easily.
{CAUTION:

lever is not fully in P (Park) with the parking brake
rmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the

more power.
Downshifting the transmission in slippery road conditions
could result in skidding, see Skidding underLoss of
Control on page 4-11.
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.
