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

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.
