Engine Coolant Heater
Your vehicle may have 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. The cord is located on the driver’s
side of the engine compartment next to the
battery box facing the engine.
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.
116

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. 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 list everything here,
we ask that you contact your dealer in the area
where you will be parking your vehicle. The
dealer/retailer can give you the best advice for that
particular area.
Active Fuel Management™
Your vehicle’s V8 engine may have Active Fuel
Management™. This system allows the engine to
operate on either all or half of its cylinders,
depending on your driving conditions.When less power is required, such as cruising at a
constant vehicle speed, the system will operate
in the half cylinder mode, allowing your vehicle to
achieve better fuel economy. When greater
power demands are required, such as accelerating
from a stop, passing, or merging onto a freeway,
the system will maintain full-cylinder operation.
Automatic Transmission Operation
There are several different positions for your gear
shift lever.
117

To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of
the air to the instrument panel outlets; then directs
most of the remaining air to the oor outlets. A little
air is directed toward the windshield and the side
window outlets. Cooler air is directed to the upper
vents and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with a little air directed to the windshield
and the side window outlets. The recirculation
button cannot be selected while in oor mode.
@(Recirculation):Recirculation mode is used
to recirculate the air inside of your vehicle. When
this button is pressed, an indicator light in the
button will come on to let you know that it is active.
Use this mode to help prevent outside odors and/or
dust from entering your vehicle or to help cool the
air inside of your vehicle more quickly. The air
conditioning compressor will also come on when
this mode is activated. While in recirculation mode,the windows may fog when the weather is cold and
damp. To clear the fog, select either the defog or
defrost mode and increase fan speed.
Defog and defrost modes are described later in this
section.
Driver’s Side Temperature Lever:The lever on
the left side of the climate control panel is
used to raise or lower the temperature on the
driver’s side of the vehicle. Slide the lever up or
down to adjust the temperature.
Passenger’s Side Temperature Lever:The lever
on the right side of the climate control panel is
used to raise or lower the temperature on the
passenger’s side of the vehicle. Slide the lever up
or down to adjust the temperature. This lever also
adjusts the temperature to the rear seat outlets.
When the temperature outside is 0°F (-18°C) or
lower, use the engine coolant heater, if the vehicle
has one, to provide warmer air, faster to your
vehicle.
#(Air Conditioning):Press this button to turn
the air-conditioning system on or off. When the
button is pressed, an indicator light will come on
and the system will begin to cool and dehumidify

Outlet Adjustment
Use the air outlets located in the center and
on the side of the instrument panel to direct
the airow.
Operation Tips

Keep the hood and front air inlets free of
ice, snow, or any other obstruction, such
as leaves. The heater and defroster will work
better, reducing the chance of fogging the
inside of your windows.
When you enter a vehicle in cold weather,
set the fan speed to maximum airow for
a few moments before driving. This helps
clear the intake ducts of snow and moisture,
and reduces the chance of fogging the
inside of your windows.
Keep the air path under the front seats
clear of objects. This helps air to circulate
throughout your vehicle.
Adding outside equipment to the front of the
vehicle, such as hood-air deectors, may
affect the performance of the heating and
air conditioning system. Check with your
dealer before adding equipment to the
outside of your vehicle.

{CAUTION:
Snow can trap exhaust gases under
your vehicle. This can cause deadly
CO (carbon monoxide) gas to get inside.
CO could overcome you and kill you. You
cannot see it or smell it, so you might not
know it is in your vehicle. Clear away
snow from around the base of your
vehicle, especially any that is blocking the
exhaust pipe. And check around again
from time to time to be sure snow does
not collect there.
Open a window just a little on the side of
the vehicle that is away from the wind.
This will help keep CO out.Run your engine only as long as you must.
This saves fuel. When you run the engine, make it
go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat
that you get and it keeps the battery charged.
You will need a well-charged battery to restart the
vehicle, and possibly for signaling later on with
your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window
almost all the way to preserve the heat. Start
the engine again and repeat this only when you
feel really uncomfortable from the cold. But do it as
little as possible. Preserve the fuel as long as
you can. To help keep warm, you can get out of
the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.

Notice:Using coolant other than DEX-COOL®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
What to Use
Use a mixture of one-half clean, drinkable water
and one-half DEX-COOL®coolant. If you use
this coolant mixture, you do not need to add
anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will.
Your vehicle’s coolant warning system
is set for the proper coolant mixture.
With plain water or the wrong mixture, your
engine could get too hot but you would not
get the overheat warning. Your engine
could catch re and you or others could be
burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice:If you use an improper coolant
mixture, your engine could overheat and be
badly damaged. The repair cost would not be
covered by your warranty. Too much water
in the mixture can freeze and crack the engine,
radiator, heater core, and other parts.

If No Steam Is Coming From Your
Engine
If you get an engine overheat warning but see or
hear no steam, the problem may not be too
serious. Sometimes the engine can get a little
too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of
steam, try this for a minute or so:
1. In heavy traffic, let the engine idle in
NEUTRAL (N) while stopped. If it is safe to
do so, pull off the road, shift to PARK (P)
or NEUTRAL (N) and let the engine idle.
2. Turn on your heater to full hot at the highest
fan speed and open the windows as
necessary.If you no longer have the overheat warning,
you can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not
come back on, you can drive normally.
If the warning continues and you have not
stopped, pull over, stop, and park your vehicle
right away.
If there is still no sign of steam, you can push
down the accelerator until the engine speed
is about twice as fast as normal idle speed for
at least three minutes while you are parked. If you
still have the warning, turn off the engine and
get everyone out of the vehicle until it cools down.
You may decide not to lift the hood but to get
service help right away.
