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.
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 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.

Interior Lamps
Instrument Panel Brightness Control
The lever for this feature is
located to the left of the
steering column.
The brightness of the instrument panel lights can be
adjusted by sliding the INTERIOR lever from LO to HI.
The instrument panel lights will be on only when the
parking lamps are on. The interior courtesy lamps can
be turned on by sliding the INTERIOR lever all the
way to the top, to HI.
Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps go on. They make it easy for you to enter
and leave the vehicle. You can also turn these lamps on
by sliding the INTERIOR lever all the way to the top.
Illuminated Entry
If it is dark enough outside when you press the button
with the unlock symbol on the remote keyless entry
transmitter, the interior courtesy lamps will turn on and
stay on for approximately 40 seconds. The lamps will
turn off immediately by pressing the button with the
lock symbol on the remote keyless entry transmitter,
turning the ignition key to RUN or activating the
power door locks.
Delayed Entry Lighting
If it is dark enough outside 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
up to 25 seconds or until the ignition is turned to an on
position. When the lamps turn off as a result of the
25 second timer or the ignition switch being turned on,
the lighting will deactivate via the theater dimming
effect. Locking the doors will override the delayed entry
lighting feature and the lamps will turn off right away.

2-48 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
If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and
stay on for approximately 25 seconds. This will give
you time to find the door pull handle or lock switches.
Once the key is inserted into the ignition the exit
lighting will be cancelled and the lighting will fade out.
Perimeter Lighting
If it is dark enough outside when the button with the
unlock symbol on the remote keyless entry transmitter is
pressed, the DRL headlamps, parking lamps and
back
-up lamps will come on.Personal Choice Programming
This feature can be programmed in the on or off mode
for each transmitter.
If your vehicle is equipped with the Driver Information
Center (DIC), you must use it to program this feature.
See ªDriver Information Center (DIC)º in the Index.
To turn the feature off, do the following:
1. Close all the doors and turn the ignition on. Keep all
doors closed throughout this procedure.
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 transmitter. Perimeter
lighting remains on at this time and the horn will
chirp two times.
4. Press the instant alarm on the transmitter again.
Perimeter lighting is disabled and the horn will chirp
one time.
5. Release the door lock switch. The perimeter lighting
feature is now off.

3-3
VENT: This setting directs outside air through the
instrument panel outlets. The air conditioning
compressor is not working when VENT is selected. If
you select VENT while in FRONT defrost, the VENT
light will flash three times to let you know this is not
allowed. This is to prevent fogging.
HTR (Heater): This setting directs most of the air
out of the floor ducts 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 outlets and the floor ducts.
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 (Maximum Air Conditioning): This setting
directs airflow through the 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.
Also in this mode, the RECIRC function is activated
to create the maximum cooling effect in the vehicle. If
RECIRC was active before selecting MAX, the light in
the RECIRC button will go off. If RECIRC is selected
after MAX, the light in the RECIRC button will not
come on.
NORM (Normal): This setting cools the outside
air entering your vehicle and directs it through the
instrument panel outlets. The air conditioning
compressor is on in this mode.
BI
-LEV (Bi-Level): This setting directs warmer air
to the floor ducts and cooler air to the instrument panel
outlets. The air conditioning compressor is on in
this mode.

3-9
On sunny days, when the air is moderately warm or
cool, use Bi
-Level to deliver warm air to the floor ducts
and cooler air to the 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 Recirculation 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 Automatic Operation, on very hot
days, the system will automatically enter recirculation
mode and the temperature door will be positioned at the
full cold position for maximum cooling. If the system is
not in the automatic mode, recirculation 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 as a result.Heating
If your vehicle has the electronic touch system, on cold
days, use HTR with the TEMPERATURE lever toward
WARM and the fan speed toward HIGH.
If your vehicle has the Dual Automatic ComforTemp
system, and on cold days, if the automatic 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 as a result. 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 automatic mode and return the system to
manual operation.
With each system, outside air will be brought in and sent
through the floor ducts. 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)
If your vehicle has this feature, you can control the
temperature function by using the buttons located on
your steering wheel.
Press the TEMP
(Temperature) up arrow
to increase the temperature
and the TEMP
(Temperature) down
arrow to decrease
the temperature.

4-29

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 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 (
)
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 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.
You may decide not to lift the hood but to get service
help right away.

5-13
The coolant level should be at or above the FULL
COLD mark (if the engine is hot, the coolant level
should be at FULL HOT). If it isn't, 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. Don't touch them. If you
do, you can be burned.
Don't run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed 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 aren't, your vehicle needs service.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL
(silicate-free) coolant.
If coolant other than DEX-COOL is 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 first. Damage caused by the
use of coolant other than DEX
-COOL
is not
covered by your new vehicle warranty.
