Engine Coolant Heater
The vehicle may have this feature. In very cold weather,
0°F (−18°C) or colder, the engine coolant heater can
help. The vehicle will start easier and get 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is attached to the underside of the vehicle’s
diagonal brace, which is located above the engine
air cleaner/lter 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 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. Unplug and store the cord as it was before to keep
it away from moving engine parts, before starting
the engine. If this is not done, the cord could
be damaged.
2-20

How long should the coolant heater be kept plugged in?
The answer depends on the outside temperature, the
kind of oil used in the vehicle, and some other
things. Instead of trying to list everything here, contact
your dealer in the area where the vehicle will be parking.
The dealer can give you the best advice for that
particular area.
Automatic Transaxle Operation
The shift lever, located on
the console between the
seats, operates the
automatic transaxle.The ignition positions are displayed on the instrument
panel cluster and will indicate the gear the vehicle is in.
Maximum engine speed is limited on the automatic
transaxle when the vehicle is in PARK (P) or
NEUTRAL (N) to protect driveline components from
improper operation.
2-21

Interior Lamps
Instrument Panel Brightness
The instrument panel lights can be brightened or
dimmed by turning the exterior lamp knob. Turning the
knob all the way clockwise turns on the courtesy
lamps.
Courtesy Lamps
When any door is opened, several courtesy lamps come
on to make it easier to enter and exit the vehicle.
These lamps can also be turned on by turning the
exterior lamps control clockwise to MAX.
Entry Lighting
The courtesy lamps will come on and stay on for a set
time whenever the UNLOCK button on the remote
keyless entry transmitter is pressed.
The lamps will stay on while a door is opened and then
turn off automatically about 25 seconds after it is
closed. If the UNLOCK button is pressed and a door is
not opened, the lamps will turn off after about
40 seconds.Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps do not turn off at
the end of the delay time. Instead, they slowly dim after
the delay time and then turn off.
The courtesy lamps turn off when the ignition key is
turned to RUN or START. They will come on again when
a door is opened.
Delayed Entry Lighting
Delayed entry lighting lights the vehicle’s interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. After all the doors have been closed, the
delayed entry lighting feature will continue to work until
one of the following occurs:
The ignition is in RUN.
The doors are locked.
Twenty ve seconds has elapsed.
If during the illumination period a door is opened, the
timed illumination period will be canceled and the interior
lamps will remain on.

VENT (Ventilation):This mode brings in outside air
and directs it through the instrument panel outlets.
BI-LEV (Bi-Level):This mode directs approximately
half of the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets.
Some air may be directed toward the windshield.
HTR (Heater):This mode directs most of the air to the
oor outlets, with some air directed to the outboard
outlets, for the side windows, and some air directed to
the windshield.
BLEND:This mode directs half of the air to go to the
oor outlets and half to the defroster and side window
outlets. The air-conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40°F (4°C).
The right knob can also be used for the defrost mode.
Information on defrosting and defogging can be
found later in this section.
9FAN:The left knob controls the fan speed.
OFF:Turn the knob all the way counterclockwise to
turn off the fan.
LO (Low Fan Speed):This setting creates the lowest
fan speed.HI (High Fan Speed):This setting creates the highest
fan speed.
DRIVER (Driver’s Side Temperature):The lever on
the left adjusts the air temperature for the driver’s
side outlets. Slide the lever up to raise the temperature
and down to lower the temperature.
PASSENGER (Passenger’s Side Temperature):The
lever on the right adjusts the air temperature for the
passenger’s side outlets. Slide the lever up to raise the
temperature and down to lower the temperature.
"(Air Conditioning):Press this button to turn the
air-conditioning on and off. An indicator light above the
button will come on when the air conditioning is on.
During daylight hours the interior lighting control might
need adjustment to the highest setting in order for the
indicator light to be seen. The system will cool and
dehumidify the air inside the vehicle when the A/C
indicator light is on.
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
For a quick cool-down on a very hot day, use MAX with
the temperature levers all the way in the blue area. If this
setting is used for long periods of time, the air in the
vehicle may become too dry.
For normal cooling on hot days, use VENT with the
temperature levers in the blue area. The system will bring
in outside air and cool it.
3-18

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
oor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
{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 can not 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 your 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.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle uid to use. SeeScheduled
Maintenance on page 6-4.
If the uid level is low, add only enough of the proper
uid to bring the level into the crosshatched area on the
dipstick. SeeRecommended Fluids and Lubricants
on page 6-12
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough uid at the
dipstick hole to bring it to the proper level.
It does not take much uid, generally less than one
pint (0.5 L). Do not overll.
Notice:Use of automatic transaxle uid labeled
other than DEXRON
®-III may damage your vehicle,
and the damages may not be covered by your
warranty. Always use DEXRON
®-III labeled automatic
transaxle uid.
3. After adding uid, recheck the uid level as
described under “How to Check,” earlier in
this section.
4. When the correct uid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs rst, if you add
only DEX-COOL
®extended life coolant.
The following explains the cooling system and how to
add coolant when it is low. If there is a problem
with engine overheating or if more coolant needs to be
added to the radiator, seeEngine Overheating on
page 5-29.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
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 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.
5-26

What to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOL®coolant which will not damage
aluminum parts. If this coolant mixture is used, nothing
else needs to be added.
{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 coolant needs to be added more than four times a
year, have your dealer check the cooling system.
Notice:If you use the proper coolant, you do not
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
Checking Coolant
The engine coolant recovery tank is located on the
passenger’s side of the vehicle at the rear of the engine
compartment. SeeEngine Compartment Overview on
page 5-12for more information on location.
The vehicle must be on a
level surface. When the
engine is cold, the coolant
level should be at the
COLD mark or a little
higher. When the engine is
warm, the level should
be up to the HOT mark or
a little higher.
5-27

If No Steam Is Coming From Your
Engine
An overheated engine warning can indicate a serious
problem. SeeEngine Coolant Temperature Warning
Light on page 3-34.
If there is an overheated engine warning, and no steam
is seen or heard, the problem may not be too serious.
Sometimes the engine can get a little too hot when
the vehicles:
Climbs a long hill on a hot day.
Stops after high-speed driving.
Idles for long periods in traffic.
Tows a trailer.
If the overheated engine warning appears 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. Adjust the heater to the highest temperature and
fan speed settings and open the window as
necessary.If the overheated engine warnings no longer exist, the
vehicle can be driven. Just to be safe, drive slower
for about 10 minutes. If the warning does not come back
on, continue to drive.
If the warning continues, and you have not stopped, pull
over, stop, and park the vehicle right away.
If there is still no sign of steam, idle the engine for three
minutes while parked. If the warning still exists, turn
off the engine and get everyone out of the vehicle until
it cools down. Also, see “Overheated Engine Protection
Operating Mode” listed previously in this section.
You may decide not to lift the hood but to get service
help right away.
5-31

If it is not, there may be a leak at the pressure cap or in
the radiator hoses, heater hoses, radiator, water
pump, or somewhere else in the cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them. If
you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine re, and you could be
burned. Get any leak xed before you drive the
vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fans are running.
If the engine is overheating, both fans should be
running. If they are not, the vehicle needs service.Notice:Engine damage from running your engine
without coolant is not covered by your warranty. See
“Overheated Engine Protection Operating Mode”
in the Index for information on driving to a safe
place in an emergency.
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 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.
