Engine Coolant Heater
Your vehicle may have an engine coolant heater. In
very cold weather, 0ÉF (-18ÉC) 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 32ÉF (0ÉC), 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 electrical cord is located on the driver's side
of the engine compartment.
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.
Automatic Transaxle Operation
Maximum engine speed is limited when you are in
PARK (P) or NEUTRAL (N), to protect driveline
components from improper operation.There are several different positions for your shift lever.
PARK (P):This gear position locks your front wheels.
It is the best position to use when you start your engine
because your vehicle cannot move easily.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle
shift lock control system. You have to fully apply
your regular brakes before you can shift from PARK (P)
when the ignition key is in RUN. As you step on the
brake pedal while in PARK (P), you may hear a
click from the solenoid of the system. This ensures that
the system is operating properly.
If you cannot shift out of PARK (P), ease pressure on
the shift lever ± push the shift lever all the way into
PARK (P) as you maintain brake application. Then move
the shift lever into the gear you wish. See
Shifting Out
of Park (P) on page 2-41.

·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 Ð 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 Automatic Transaxle
Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle ¯uid to use. SeeRecommended Fluids
and Lubricants on page 6-12.
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 over®ll.
Notice:Use of automatic transaxle ¯uid labeled
other than DEXRONž-III may damage your vehicle,
and the damages may not be covered by your
warranty. Always use DEXRON
ž-III labeled automatic
transaxle ¯uid.
3. After adding ¯uid, recheck the ¯uid level as
described under ªHow to Check Automatic
Transaxle Fluidº.
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-COOLžengine 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
žextended 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, see
Engine Overheating
on page 5-25.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
žcoolant will:
·Give freezing protection down to-34ÉF (-37ÉC)
·Give boiling protection up to 265ÉF (129ÉC)
·Protect against rust and corrosion
·Help keep the proper engine temperature
·Let the warning messages and gages work
as they should
Notice:Using coolant other than DEX-COOLžmay
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
ž(silicate-free) coolant in your vehicle.
5-22

What Engine Coolant to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOLžcoolant 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
žcoolant.
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 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 do not
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.

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. If your air conditioner is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you are in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving ± AUTOMATIC OVERDRIVE (D) or
THIRD (3).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, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam, 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. Also, see ªOverheated
Engine Protection Operating Modeº listed previously
in this section.
You may decide not to lift the hood but to get service
help right away.
