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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
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
Your automatic transaxle has a shift lever located on the
steering column.
PARK (P): This position locks your front wheels.
It's the best position to use when you start your engine
because your vehicle can't move easily.
CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
See ªShifting Into PARK (P)º in the Index. If
you're pulling a trailer, see ªTowing a Trailerº in
the Index.

2-43 Illuminated Entry (If Equipped)
Press the UNLOCK button on the remote keyless entry
transmitter (if equipped) and the interior courtesy lamps
will turn on and stay on for up to one minute. The lamps
will turn off immediately by pressing the LOCK button
on the remote keyless entry transmitter, starting the
engine or activating the power door locks.
Delayed Entry Lighting
When you open the door, the interior lamps will turn 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. Note that locking the
doors will override the delayed entry lighting feature
and the lamps will turn off right away.
Theater Dimming
This feature allows for a three to five-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
With this feature, the interior lamps will turn on and stay
on for up to 25 seconds after you remove the key from
the ignition. This will give you time to find the door pull
handle or lock switches.
Perimeter Lighting (If Equipped)
When the UNLOCK button on the remote keyless entry
transmitter is pressed, the headlamps, parking lamps,
back
-up lamps and cornering lamps will turn on if it is
dark enough outside according to the twilight sentinel.
If your vehicle is not equipped with twilight sentinel
and perimeter lighting is active, the lights will turn on
whenever the UNLOCK button on the transmitter
is pressed.
Personal Choice Programming
This feature can be programmed in the on or off mode
for each transmitter.
To turn the feature off:
1. Turn the ignition key to OFF.
2. Press and hold LOCK on the power door lock switch
throughout this procedure. All the doors will lock.
3. Press the instant alarm on the remote keyless entry
transmitter. Perimeter lighting remains on at this
time and the horn will chirp two times.

VENT: This setting directs outside air through the
middle instrument panel outlets. The air conditioning
compressor is not working when VENT is selected.
HTR: This button directs air out of the heater outlets.
Most of the air will come from the floor outlets while
some air will flow through the windshield and side
window outlets. The air conditioning compressor is not
working when HTR is selected.
BLEND: When BLEND is selected, the airflow will be
split between the windshield and the floor outlets. The
air conditioning compressor will be operating.
FRONT: This setting directs most of the airflow toward
the windshield.
OFF: The ventilation system always allows fresh air to
flow through your vehicle when it is moving. The
system will try to keep the air at a previously chosen
temperature. When the system is off, the blower fan is
also off.
MAX: This setting directs airflow through the middle
instrument panel outlets. The amount of outside air
entering your vehicle is limited with this setting. The air
conditioning compressor is on in this mode.NORM: This setting cools the outside air entering your
vehicle and directs it through the middle instrument
panel outlets. The air conditioner is on in this mode.
BI
-LEV: This setting directs warm air to the floor and
cooler air to the middle instrument panel outlets. The air
conditioner is on in this mode.
Dual Automatic Comfortemp
Climate Control (If Equipped)
If your vehicle has the Dual Automatic Comfortemp
Climate Control option, the following information tells
you how it works.
You will hear a beep each time a button is pushed and a
light on the button will indicate which function is active.
The lights are on all buttons except TEMP, FAN and
AIR FLOW. The display will show fan speed, comfort
level setting and airflow direction for a few seconds
whenever AUTO is selected, and then it will display the
outside temperature. The outside temperature reading is
most accurate when the vehicle is moving. During stops,
the display shows the previous temperature for best
accuracy and system control.

On sunny days, when the air is moderately warm or
cool, use BI
-LEV to deliver warm air to the floor and
cooler air to the middle instrument panel outlets. On
days like these, the sun may adequately warm your
upper body, but your lower body may not be warm
enough. To warm or cool the air delivered, adjust the
TEMPERATURE lever.
The amount of fresh air entering the vehicle is limited
when RECIRC is selected. This is helpful when you are
trying to cool the air in your vehicle or limit the air
entering the vehicle.
If your vehicle has the Dual Automatic Comfortemp
system and it is set for AUTO, on very hot days, the
system will automatically enter the RECIRC mode and
the temperature door will be positioned at the full cold
position for maximum cooling. If the system is not in
the AUTO mode, RECIRC should be selected to provide
maximum cooling. You can choose the extreme comfort
setting of 60
F (16
C), but the system will not cool any
faster by choosing the extreme comfort setting.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle's engine speed and
power. This is normal because the system is designed to
cycle the compressor on and off to keep the
desired temperature.Heating
If your vehicle has the electronic touch system, on
cold days, use HTR with the TEMPERATURE lever
toward WARM.
If your vehicle has the Dual Automatic Comfortemp
system, and on cold days, if the AUTO mode is selected,
the system will automatically direct the air toward the
floor and the temperature door will be positioned at the
full hot position. You can choose the extreme comfort
setting of 90
F (32
C) but the system will not warm up
any faster by selecting the extreme comfort setting. If
the outside temperature is cold, the fan will be delayed
to avoid blowing cold air. Pushing the FAN, AIR FLOW
or FRONT buttons will override this delay, turn off the
AUTO mode and change the fan speed.
With each system, 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.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

When the engine idles for a long time, the exterior
temperature sensor may cause the system to blow air
that is too cool. Once the vehicle is moving again,
the system will try to maintain the set temperature
inside your vehicle.

When you start your vehicle and the EXT display
flashes (Dual Automatic Comfortemp system only)
for some time, the system may need repair. See
your dealer.Steering Wheel Controls for Climate
Control (If Equipped)
G±43±2200±V
If your vehicle has this
feature, you can control the
temperature function by
using the button on your
steering wheel. Press the
TEMP up arrow to increase
the temperature and the
TEMP down arrow to
decrease the temperature.

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.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
You can tow your vehicle behind another vehicle for use
at your destination. Be sure to use the proper towing
equipment designed for recreational towing. Follow the
instructions for the towing equipment.
To tow your vehicle, follow these steps:
1. Put the front wheels on a dolly.
2. Put the vehicle in PARK (P).
3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight
-ahead position
with a clamping device designed for towing.
5. Release the parking brake.
