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. 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 ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
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 briey
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/retailer. If you do not, the engine
might not perform properly. Any resulting damage
would not be covered by the vehicle warranty.
Engine Coolant 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. An internal thermostat in
the plug-end of the cord may exist 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 passenger side of the
engine compartment, near the radiator.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a re.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts, to prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking the vehicle for the
best advice on this.

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,
seeTowing a Trailer on page 4-33.
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 4-12.
2-25

I (Intermediate):This position is also used for normal
driving. However, it reduces vehicle speed without
using the brakes for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If constant upshifting or downshifting occurs while
driving up steep hills, this position can be used to
prevent repetitive types of shifts. You might choose
I (Intermediate) instead of D (Drive) when driving on hilly,
winding roads and when towing a trailer, so that there is
less shifting between gears.
L (Low):This position reduces vehicle speed more
than I (Intermediate) without actually using the brakes.
You can use it on very steep hills, or in deep snow
or mud. If the shift lever is placed in L (Low), the
transmission will not shift into L (Low) until the
vehicle is going slowly enough.
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.Transmission Overheating
If the transmission uid temperature rises above
284°F (140°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-32for
more information. When the transmission overheats it will
go into a protection mode and will default shift into fth
gear if in the D (Drive) position, or second gear if in the
L (Low) position. Continue driving the vehicle in either
position depending on the required vehicle speed and
load. Once the uid temperature lowers to the normal
temperature range, the transmission will return to the
normal shift patterns. Towing or driving on long hills can
cause the transmission uid temperature to be higher
than normal. If the transmission uid temperature will
not cool, you may need to pull over and check the
transmission uid level. You should also check the
engine coolant temperature. If it is hot, seeEngine
Overheating on page 5-28.
2-26

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:
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 4-33.
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 is in ON/RUN.
2-27

If you cannot shift out of P (Park), ease pressure on the
shift lever and push the shift lever all 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.
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.
2-28

In manual shift mode all six forward gears can be
selected.
While using the MSM (Manual Shift Mode) feature
the vehicle will have operation similar to a manual
transmission. You can use this for sport driving or when
driving hilly roads to stay in gear longer or to downshift
for more power or engine braking.
The transmission will only allow you to shift into gears
appropriate for the vehicle speed:
The transmission will not automatically shift to the
next higher gear without moving the shift lever.
The transmission will not allow shifting to the next
lower gear if the vehicle speed is too high.
If the vehicle does not respond to a gear change, or
detects a problem with the transmission, the range
of gears may be reduced and the Malfunction Indicator
Lamp will come on. SeeMalfunction Indicator Lamp
on page 3-34.
Transmission Overheating
If the transmission uid temperature rises above
270°F (132°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-32for
more information. When the transmission overheats it
will go into a protection mode and will default into a
different shift sequence to help cool the transmission
uid. This shift sequence is the same for both D (Drive)
position and manual mode. Continue driving the vehicle
in either position depending on the required vehicle
speed and load. Once the uid temperature lowers to the
normal temperature range, the transmission will return to
the normal shift patterns. Towing or driving on long hills
can cause the transmission uid temperature to be higher
than normal. If the transmission uid temperature will
not cool, you may need to pull over and check the
transmission uid level. You should also check the
engine coolant temperature. If it is hot, seeEngine
Overheating on page 5-28.
2-30

Make sure to release the parking brake before driving
the vehicle.
If the parking brake is applied and the vehicle is moving
at least 4 mph (6 km/h), a chime will activate to
remind you to release the parking brake.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
Shifting Into Park
{CAUTION:
It can be 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.
CAUTION: (Continued)
CAUTION: (Continued)
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, use the steps that
follow. If you are pulling a trailer, seeTowing a
Trailer on page 4-33.
1. Hold the brake pedal down and set the parking
brake. SeeParking Brake on page 2-31for more
information.
2. Move the shift lever into P (Park) by pressing the
button on the shift lever and pushing the 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 key, the vehicle is in
P (Park).
2-32

Leaving the Vehicle With the Engine
Running
{CAUTION:
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 rmly set. And, if you leave the vehicle with
the engine running, it could overheat and even
catch re. 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
rmly 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 rst pressing the button on the
console shift lever. If you can, it means that the shift
lever was not fully locked into 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 nd
out how, see ‘‘Shifting Into P (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).
Shifting Out of Park
The 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.
