Engine Coolant Heater
Your vehicle may be equipped with this feature. 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
cord is attached to the underside of the 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
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.
Automatic Transaxle Operation
Your automatic transaxle has a shift lever located on
the console between the front seats.
The above graphic is displayed on your instrument
panel cluster.
Maximum engine speed is limited on automatic transaxle
vehicles while you're in PARK (P) or NEUTRAL (N) to
protect driveline components from improper operation.
2-21

Entry Lighting
Your vehicle may have the entry lighting feature. Your
courtesy lamps will come on and stay on for a set
time whenever you press UNLOCK on the remote
keyless entry transmitter.
If you open a door, the lamps will stay on while it's open
and then turn off automatically about 25 seconds after
you close it. If you press UNLOCK and don't open
a door, the lamps will turn off after about 40 seconds.
Illuminated entry includes a feature called theater
dimming. With theater dimming, the lamps don't just
turn off at the end of the delay time. Instead, they slowly
dim after the delay time until they go out. The delay
time is canceled if you turn the ignition key to ON
or press the power door lock switch.
When the ignition is on, illuminated entry is inactive,
which means the courtesy lamps won't come on unless
a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. Immediately after both doors have been closed,the delayed entry lighting feature will continue to work
until one of the following occurs:
·The ignition is moved to ON,
·the doors are locked or
·an illumination period of 25 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.
Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the key is removed from the ignition.
The vehicle's ignition must be off for delayed exit
lighting to work.
When the key is removed, interior illumination will
activate and remain on until one of the following occurs:
·The ignition is moved to ON,
·the power door locks are activated or
·an illumination period of 25 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.

?(Recirculation):Press this button to turn the
recirculation mode on. When this mode is on, inside air
and a small percentage of outside air will recirculate
throughout your vehicle. This selection will reduce
the entry of outside air and odors from entering your
vehicle, it may also help heat or cool your vehicle more
quickly. When this button is pressed, an indicator
light in the button will also come on to let you know that
it is activated. During daylight hours, you may have
to adjust the instrument panel brightness control to the
highest setting in order to see the indicator light.
See
Interior Lamps on page 3-17for more information.
The recirculation mode can be used with vent and
bi-level modes, but it cannot be used with ¯oor, defog,
defrost or outside air modes.
This system will default back to the outside air setting,
so you will have to re-select this setting every time
that you start the vehicle.
If the weather is cold and damp, the system may cause
the windows to fog while using the recirculation
mode. If the windows do start to fog, do the following:
1. Select the defog or defrost mode.
2. Select the temperature.
3. Select the highest fan speed.
4. Operate the system in the outside air mode, to help
prevent a recurrence.
Heating
Adjust the air temperature by using the following levers:
D (Driver):Slide this lever up or down to raise or
lower the temperature on the driver's side of the vehicle.
P (Passenger):Slide this lever up or down to raise
or lower the temperature on the passenger's side of the
vehicle.
To warm your vehicle on cold days, do the following:
1. Select the ¯oor mode.
2. Select the warmest temperature.
3. Select the fan speed.
4. Select outside air mode, after the air has warmed,
to prevent it from becoming too stale.
When it's cold outside 0ÉF (-18ÉC) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
see
Engine Coolant Heater on page 2-20.

·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't 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
doesn't collect there.
Open a window just a little on the side of the
vehicle that's 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.

Notice:When adding coolant, it is important that
you use only DEX-COOLž(silicate-free) coolant.
If coolant other than DEX-COOLžis 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 ®rst.
Damage caused by the use of coolant other
than DEX-COOL
žis not covered by your new vehicle
warranty.
What to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOLžcoolant 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 such as alcohol, can boil
before the proper coolant mixture will.
CAUTION: (Continued)
CAUTION: (Continued)
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
ž
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.

If No Steam Is Coming From Your
Engine
An overheat warning along with a low coolant message
can indicate a serious problem.
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)l 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, 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. 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.
