Engine Coolant Heater
If your vehicle has this feature, in very cold weather,
0°F (−18°C) or colder, the engine coolant heater can
help. You’ll 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on the
passenger’s side of the vehicle, above the 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 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. 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.

Interior Lamps
Instrument Panel Brightness
Adjust the instrument panel light brightness by turning
the exterior lamps control.
Courtesy Lamps
When any door is opened, several lamps go on.
They make it easy for you to enter and leave your vehicle.
You can also turn these lamps on by turning the exterior
lamps control clockwise all the way past the normal stop.
Entry Lighting
When you open either front door or press the unlock
button on the remote keyless entry transmitter, the lamps
inside your vehicle will turn on. These lamps will turn off
after about 40 seconds. These lamps will also turn off if
you start the engine or activate the power door locks.
Delayed Entry Lighting
When you open the door, the interior lamps will come on.
When you close the door with the ignition off, the interior
lamps will stay on for 25 seconds or until the ignition is
turned to an on position. Locking the doors with thepower door lock switch will override the delayed entry
lighting feature and the lamps will turn off right away.
Using the remote keyless entry transmitter to lock the
door will not cancel delayed lighting.
Theater Dimming
This feature allows for a three to ve-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
With this feature, the interior lamps will come on for
25 seconds after you remove the key from the ignition.
This will give you time to nd the door handle or
lock switches.
Parade Dimming
This feature prohibits the dimming of your instrument
panel displays during daylight while your headlamps are
on. This feature operates with the light sensor for the
Twilight Sentinel
®and is fully automatic. When the light
sensor reads darkness outside, you will be able to
dim your instrument panel displays once again.

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. SeePart D: Recommended
Fluids and Lubricants on page 6-25.
If the uid level is low, add only enough of the proper
uid to bring the level into the cross-hatched area on the
dipstick.
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:We recommend you use only uid labeled
DEXRON
®-III, because uid with that label is
made especially for your automatic transmission.
Damage caused by uid other than DEXRON
®-III is
not covered by your new vehicle warranty.
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 your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your 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 your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-28.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®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.
5-25

What to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOL®coolant which will not damage
aluminum parts. 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 wouldn’t be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice:If you use the proper coolant, you don’t
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
Checking Coolant
The coolant recovery tank is located in the engine
compartment on the driver’s side of the vehicle.
SeeEngine Compartment Overview on page 5-12for
more information on location.

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 window 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 doesn’t 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’s still no sign of steam, you can idle the engine
for three minutes while you’re parked. If you still
have the warning,turn off the engine and get everyone
out of the vehicleuntil it cools down.
You may decide not to lift the hood but to get service
help right away.

SeeEngine Compartment Overview on page 5-12for
more information on location.
The coolant level should be at or above the FULL
COLD mark. If it is not, you may have 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, your vehicle needs service.
Notice:Engine damage from running your engine
without coolant isn’t covered by your warranty.
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.
