Engine Coolant Heater
Your vehicle may be equipped with an engine
coolant heater.
In very cold weather, 0°F (−18°C) or colder, the
engine coolant heater can help. You will get easier
starting and better fuel economy during engine
warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
For the 3.6L V6 engine, the cord is located in
the engine compartment on the passenger’s
side of the vehicle in front of the fuse block.
For the 4.6L V8 engine, the cord is located in
the engine compartment on the driver’s
side of the vehicle near the inner fender and
above the strut.
For the 4.4L V8 engine, the cord is located in
the front of the engine compartment, on
the passenger’s side of the vehicle. The plug
will be inside the upper grille cutout.
3. You must remove the plastic cap to access
the plug.

4. 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.
5. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to listeverything here, we ask that you contact your
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.Automatic Transmission Operation
The shift lever is located on the center console
between the front seats.
There are several
different positions for
the shift lever.
PARK (P):This position locks the rear wheels.
It is the best position to use when you start
the engine because your vehicle cannot move
easily.
116

{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not leave your 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 your vehicle will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P). See
Shifting Into Park (P) on page 122.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 357.
Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transmission shift lock control system.You must fully apply your regular brakes rst and
then press the shift lever button before you
can shift from PARK (P) when the vehicle is
running. If you cannot shift out of PARK (P), ease
pressure on the shift lever and push the shift
lever all the way into PARK (P) as you maintain
brake application. Then press the shift lever button
and move the shift lever into another gear. See
Shifting Out of Park (P) on page 124.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage
the transmission. The repairs would not be
covered by your warranty. Shift to
REVERSE (R) only after your vehicle is
stopped.
REVERSE (R):Use this gear to back up.
At low vehicle speeds, you can also use
REVERSE (R) to rock your vehicle back and forth
to get out of snow, ice, or sand without damaging
your transmission. SeeIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on page 348for
additional information.
117

NEUTRAL (N):In this position, the engine does
not connect with the wheels. To restart when
you are already moving, use NEUTRAL (N) only.
You can also use NEUTRAL (N) when your
vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) with the engine running at high
speed may damage the transmission. The
repairs would not be covered by your warranty.
Be sure the engine is not running at high
speed when shifting your vehicle.DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
Going less than 35 mph (55 km/h), push
the accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
The transmission will shift down to a lower
gear and have more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
underLoss of Control on page 332.
118

If your vehicle has the V6 engine and 5-speed
transmission, when shifting manually, the number
displayed on the Driver Information Center (DIC)
indicates the highest gear allowed (1,2,3,4,5).
If First (1) or Second (2) gear is selected, the
transmission will stay in that gear. If a higher
gear position is selected, the transmission will
automatically shift between the Second (2) gear
position up to the selected gear.
If your vehicle has the V8 engine and 6-speed
transmission, when shifting manually, the number
displayed on the Driver Information Center (DIC)
indicates the gear that the transmission is in.
When starting the vehicle from a stopped condition,
only First (1) and Second (2) gear may be used.
While using the DSC feature the vehicle will
have rmer shifting and increased performance.
You can use this for sport driving or when
climbing/descending hills to stay in gear longer or
to down shift for more power or engine braking.The transmission will only allow you to shift into
gears appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission
will not automatically shift to the next higher
gear if the engine RPM is too high.
If shifting is prevented for any reason, the selected
gear will ash multiple times, indicating that the
transmission has not shifted gears.
The transmission will allow you to shift to the gear
selected and will automatically downshift when
the vehicle comes to a stop. This will allow
for more power during take-off and passing.
120

Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your 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 357.To shift into PARK (P), use the following steps:
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by
pressing the button on the front of the
shift lever while pushing the lever all the way
toward the front of the vehicle. Release
the button.
3. With your right foot still holding the brake
pedal down, set the parking brake with
your left foot. SeeParking Brake on page 121
for more information.
4. Turn the ignition off.
122

Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle
could move suddenly if the shift lever is
not fully in PARK (P) 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 your
vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P)
and your parking brake is rmly set before you
leave it. After you have moved the shift lever into
PARK (P), hold the regular brake pedal down.Then, see if you can move the shift lever away
from PARK (P) without rst pushing the button on
the shift lever. If you can, it means that the
shift lever was not fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you do not shift
your transmission into PARK (P) properly,
the weight of the vehicle may put too much force
on the parking pawl in the transmission. You
may nd it difficult to pull the shift lever out
of PARK (P). This is called “torque lock.” To
prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave
the driver’s seat. To nd out how, see “Shifting Into
PARK (P)” listed previously.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to
take some of the pressure from the parking pawl
in the transmission, so you can pull the shift
lever out of PARK (P).
123

Shifting Out of Park (P)
Your vehicle has an automatic transmission shift
lock control system. You have to fully apply
your regular brake before you can shift from
PARK (P) when the vehicle is running. See
Automatic Transmission Operation on page 116.
If you cannot shift out of PARK (P), ease pressure
on the shift lever – push the shift lever all the
way into PARK (P) and release the shift lever
button as you maintain brake application. Then
press the shift lever button and move the
shift lever into the gear desired.
If you ever hold the brake pedal down but still
cannot shift out of PARK (P), try this:
1. Press the regular bake.
2. Press the Acc. button twice to place the
ignition in accessory mode.
3. Apply and hold the brake until the end of
Step 4.
4. Shift to NEUTRAL (N).
5. Start the engine and then shift to the drive
gear you want.
6. Have your vehicle inspected by your dealer
as soon as possible.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
