You can also store an exit position for each driver.
The exit position is programmed by moving the seat
to the desired exit position and then holding the exit
symbol button for more than three seconds. The exit
position set will be for the most recently selected driving
position (1 or 2). A double beep will sound when the
memory is set.
To use exit, your vehicle must be in PARK (P). Push
and release the exit symbol button and the seat will
move to the exit position stored for the most recently
selected driver. You will hear one beep.
To stop recall movement of the seat at any time,
press one of the three memory buttons or one of the
power seat controls located on the outboard side of
the driver's seat.
If your vehicle is equipped with a Driver Information
Center (DIC), you can use it to program certain
functions of the memory seats. See ªDriver Information
Center (DIC) Vehicle Customizationº in the Index.Heated Front Seats (Option)
The heated seat switches
are located in the center
console switchbank.
This feature will quickly heat the lower cushions and
lower back of the driver's and front passenger's seat for
added comfort. The left switch is for the driver's seat
and the right switch is for the front passenger's seat.
Press the top of the switch to turn the heater on.
Press the bottom of the switch to turn the heater off.
The heated seat switch will turn off when the ignition
is turned to OFF and will resume operation when the

3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for a maximum of 15 seconds. This clears
the extra gasoline from the engine. If the engine still
won't start or starts briefly but then stops again,
repeat Step 1 or 2, depending on temperature.
When the engine starts, release the key and the
accelerator pedal.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
Engine Coolant Heater (If Equipped)
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.

2-32
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 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.
Automatic Transaxle Operation
Maximum engine speed is limited when you're 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's the best position to use when you start your engine
because your vehicle can't move easily.

3-2
Comfort Controls
This section tells you how to make your air system work
for you.
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has
a flow
-through ventilation system described later in
this section.
Dual Manual Comfort Control
Fan Knob
The left knob is used to select the force of air you want.
Turn the knob clockwise to increase fan speed and
counterclockwise to decrease fan speed. The fan must be
turned on for the air conditioning compressor to operate.Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn the knob clockwise
(toward the red area) for warmer air. Turn the knob
counterclockwise (toward the blue area) for cooler air.
Mode Knob
The right knob is used to select and determine the
direction of the air flowing into the vehicle.
(Upper): This setting directs air through the
instrument panel outlets and the rear console outlets.
(Bi-Level): This setting directs air into your
vehicle in two ways. Cooler air is directed toward your
upper body through the front instrument panel outlets
and the rear console outlets, while warmed air is
directed through the heater ducts at your feet.
(Lower): This setting brings in most of the air
through the floor ducts. It is also used to send air to the
rear of the vehicle. Keep the area under the front seats
free of objects that could obstruct airflow to the rear of
the vehicle.

3-4
Heating
Turn the temperature knob clockwise (toward the red
area) to warm the air.
In the lower mode, outside air will be brought in and
sent through the floor outlets. The heater works best if
you keep your windows closed while using it.
The bi
-level setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
For the best results, move the temperature knob to the
middle position, and then adjust it for comfort.
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35
F (2
C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed
until the engine is warmed up. This is a normal
condition designed to provide heat to the passenger
compartment and defrost the windows more quickly.
If your vehicle is equipped with an engine coolant heater
and you use it during cold weather, 0
F (
-18
C) or
lower, your heating system will provide heat more
quickly because the engine coolant is already warmed.
See ªEngine Coolant Heaterº in the Index.Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To rapidly defrost the windshield, turn the temperature
knob all the way clockwise (to the red area) and turn the
mode knob to defrost. Adjust the fan to the highest speed.
To keep the windshield clear and bring in heated air
through the heater ducts, turn the mode knob to defog.
When the temperature outside is above freezing, the air
conditioner compressor will run in these settings to help
remove moisture from the air.
Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
to the bi
-level setting and adjust the fan to the highest
speed. Aim the side vents on the instrument panel
toward the side windows. For increased airflow to the
side vents, close the center vents.
Operating the HVAC system in the recirculation mode may
cause fogging of the vehicle's windows when the weather is
cold and damp. To clear the fog, switch the HVAC system to
either the defog or defrost mode and increase the fan speed.
To avoid re
-fogging of the windows, operate the HVAC
system in the outside air mode.
For additional information, refer to ªRecirculationº
earlier in this section.

3-8
Heating
Turn the temperature knob to the desired interior
temperature to warm the air.
In the lower mode, outside air will be brought in and
sent through the floor outlets. The heater works best if
you keep your windows closed while using it.
The bi
-level setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.

Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To defrost the windows quickly, press the defrost button
and set the temperature to 90
F (32
C) and select a high
fan speed.
To warm passengers while keeping the window clear,
select the defog mode with the mode button (the defog
symbol will be lit). Select the fan speed for comfort and
windshield clearing performance.

3-10 Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
is running.
Your vehicle has air outlets that allow you to adjust
the direction and amount of airflow inside the vehicle.
Push the outlet up or down to direct the airflow.
Opening and closing the louvers will also direct airflow
from side to side.Ventilation Tips

Keep the hood and front air inlet free of ice, snow
or any other obstruction (such as leaves). This will
allow the heater and defroster to work much better,
reducing the chance of fogging the inside of
your windows.

When you enter a vehicle in cold weather, select the
lower mode and set the fan to the highest setting for
a few moments before driving off. This helps clear
the intake ducts of snow and moisture, and reduces
the chance of fogging the inside of your windows.

Keep the air path under the front seats and around
the base of the center console clear of objects.
This helps air to circulate throughout your vehicle.

If the airflow seems very low when the fan is
adjusted to the highest setting, your passenger
compartment air filter may need replacement.
See ªPassenger Compartment Air Filterº in the
Index for more information.

4-31

Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

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, floor
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.

5-11
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty. See ªOverheated
Engine Protection Operating Modeº in the Index
for information on driving to a safe place in
an emergency.
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're in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (D).
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, 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 vehicle until 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.
