2-23 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located behind the driver's side
headlamp assembly.
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 fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't 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. If you don't, 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'll be parking your
vehicle. The dealer can give you the best advice for
that particular area.

If the LOW TRAC light comes on, slippery road
conditions may exist, so you should consider slowing
down and adjusting your driving accordingly.
Engine Coolant Temperature Gage
You have a gage that
shows the engine coolant
temperature. If the gage
moves into the shaded
area near the hot mark,
your engine is too hot.
That reading means the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
If this light comes on,
your system is low on
coolant, and the engine
may overheat.
This light will come on briefly when the ignition is
turned to ON. This is normal.
See ªEngine Coolantº in the Index for more information,
and have your vehicle serviced as soon as possible.

3-4 Air Conditioning
On very hot days, open the windows long enough to let
hot inside air escape. This reduces the time the
compressor has to run, which should help fuel economy.
For quick cool
-down on very hot days, use RECIRC
with the temperature knob turned all the way to the blue
area and the A/C button pushed. If this setting is used
for long periods of time, the air in your vehicle may
become too dry.
For normal cooling on hot days, use UPPER with the
temperature knob turned to the blue area. With the A/C
button and the outside air button pushed in, the system
will bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. To
remedy this, you can use BI
-LEVEL with the
temperature knob in the middle with the A/C button and
the outside air button pushed in. The system will bring
in outside air and direct it to your upper body, while
sending slightly warmed air to your lower body. You
may notice the temperature difference more at some
times than others.
Heating
On cold days use FLOOR and the outside air button
pushed in with the temperature knob turned all the way
to the red area. The system will bring in outside air, heat
it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine
coolant heater warms the coolant your engine and
heating system use to provide heat. See ªEngine
Coolant Heaterº in the Index.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use UPPER and the outside air button
to direct air through your vehicle. Your vehicle also has
the flow
-through ventilation system described later in
this section.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob turned all the way
to the red area. To warm passengers while keeping the
windows clear, use DEFOG.

3-8
DEFROST: This setting directs most of the air
through the defrost and side window vents. Some of
the air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting unless
the outside temperature is below 38
F (3.3
C).
(Even when the compressor is running, you can control
the temperature).
RECIRC: This setting recirculates the air inside
of your vehicle. This setting is not available in defog or
defrost mode. When operating the system in the
RECIRC mode, the windows may fog up when the
weather is cold and damp. To clear the fog, select either
the DEFOG or DEFROST mode and increase the fan
speed. To avoid re
-fogging of the windows, use the
OUTSIDE AIR mode.
OUTSIDE AIR: This setting brings in outside air.
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time the
compressor has to run, which should help fuel economy.
For quick cool
-down on very hot days, use UPPER and
RECIRC. If this setting is used for long periods of time,
the air in your vehicle may become too dry.For normal cooling on hot days, use UPPER and
OUTSIDE AIR with the compressor on. The system will
bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. To
remedy this, you can use BI
-LEV with the compressor
on. The system will bring in outside air and direct it to
your upper body, while sending slightly warmed air to
your lower body. You may notice this temperature
difference more at some times than others.
Heating
On cold days use LOWER. The system will bring in
outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.

5-9
To disconnect the jumper cables from both vehicles, do
the following:
1. Disconnect the black negative (
-) cable from the
heavy, unpainted metal engine part on the vehicle
that had the dead battery.
2. Disconnect the black negative (
-) cable from
the negative (
-) terminal on the vehicle with the
good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº and ªRecreational Vehicle Towingº in
the Index.
Engine Overheating
You will find a coolant temperature gage and a warning
light about a hot engine on your instrument panel
cluster. See ªEngine Coolant Temperature Gageº in
the Index. You also have a low coolant light on your
instrument panel cluster. See ªLow Coolant Lightº in
the Index.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation.
Should an overheated engine condition exist, an
overheat protection mode which alternates firing groups
of cylinders helps prevent engine damage. In this mode,
you will notice a significant loss in power and engine
performance. The low coolant light may come on and
the temperature gage will indicate an overheat condition
exists. Towing a trailer in the overheat protection mode
should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life system. See ªEngine Oilº in the Index.

6-23
A 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant will:

Give freezing protection down to
-34F (-37C).

Give boiling protection up to 265F (129C).

Protect against rust and corrosion.

Help keep the proper engine temperature.

Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you use
only DEX
-COOL (silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX
-COOL is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half clean, drinkable water and
one
-half DEX-COOL coolant which won't damage
aluminum parts. If you use this coolant mixture, you
don't need to add anything else.
CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like 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 wouldn't
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a 50/50 mixture of clean, drinkable water
and DEX
-COOL coolant.

Scheduled Maintenance
7-14
100,000 Miles (166 000 km)

Replace spark plugs.
