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 about three seconds. If the vehicle starts
briefly but then stops again, do the same thing.
This time keep the pedal down for five or six
seconds to clear the extra gasoline from the engine.
After waiting about 15 seconds, repeat the normal
starting procedure.
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 (Option)
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.

2-24 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located behind the driver's side
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.
Automatic Transaxle Operation
Your automatic transaxle
has a shift lever located
on the console between
the seats.

If the LOW TRAC light comes on, slippery road
conditions may exist, so you should consider slowing
down and adjusting your driving accordingly.
Engine Coolant Temperature Gage
You have a gage that
shows the engine coolant
temperature. If the gage
moves into the shaded area
near the hot mark, your
engine is too hot.
That reading means the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
If this light comes on,
your system is low on
coolant, and the engine
may overheat.
This light will come on briefly when the ignition is
turned to ON. This is normal.
See ªEngine Coolantº in the Index for more
information, and have your vehicle serviced as
soon as possible.

(Recirculation): This button is used to recirculate
much of the air inside your vehicle. This setting is not
available in defogger or defroster. Operating the system
in recirculation may cause the windows to fog up when
the weather is cold and damp. To clear the fog, use the
defog or defrost modes and increase the fan speed. To
avoid refogging of the windows, use the outside air
mode.
(Outside Air): This button is used to bring
outside air into the vehicle.
Air Conditioning
On very hot days, open the windows long enough
to let hot inside air escape. This reduces the time
the compressor has to run, which should help with
fuel economy.
For quick cool
-down on very hot days, use the
vent outlets, recirculation with the temperature knob
turned all the way to the blue area, the air conditioner
on, and the fan on a high setting. If this setting is used
for long periods of time, the air in your vehicle may
become too dry.For normal cooling on hot days, use the vent outlets
with the temperature knob turned to the blue area. With
the A/C button and the outside air button pressed in, the
system will bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. To
remedy this, you can use bi
-level with the temperature
knob in the middle with the A/C button and the outside
air button pressed. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice the
temperature difference more at some times than others.
Heating
On cold days turn the fan on and use floor and the
outside air button pressed in with the temperature knob
turned all the way to the red area. The system will bring
in outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.

3-9
For normal cooling on hot days, use the vent outlets and
outside air with the air conditioning. The system will
bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
To remedy this, you can use bi
-level with the air
conditioning on. The system will bring in outside air and
direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice this
temperature difference more at some times than others.
Heating
On cold days use the floor mode and the temperature
turned toward red, with a high fan setting. The system
will bring in outside air, heat it and send it to the
floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine
coolant heater warms the coolant your engine and
heating system use to provide heat. See ªEngine
Coolant Heaterº in the Index.Ventilation
For mild outside temperatures when little heating or
cooling is needed, use the vent outlets, a fan setting,
ECON and outside air to direct outside air through your
vehicle. Your vehicle also has the flow
-through
ventilation system described later in this section.
Defogging and Defrosting
Your system has two settings for clearing the front
and side windows. To defrost the windows quickly,
use the defrost button. To warm passengers while
keeping the windows clean, select defog by pressing
the MODE button.

Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
ªRoadside Assistanceº in the Index. If you want to tow
your vehicle behind another vehicle for recreational
purposes (such as behind a motorhome), see
ªRecreational Vehicle Towingº in the Index.
Engine Overheating
You will find a coolant temperature gage and a warning
light about a hot engine on your instrument panel
cluster. See ªEngine Coolant Temperature Gageº in the
Index. You also have a low coolant light on your
instrument panel cluster. See ªLow Coolant Lightº in
the Index.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle
to be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an overheat
protection mode which alternates firing groups of
cylinders helps prevent engine damage. In this mode,
you will notice a significant loss in power and engine
performance. The low coolant light may come on
and the temperature gage will indicate an overheat
condition exists. Driving extended miles (km) and/or
towing a trailer in the overheat protection mode should
be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life system. See ªEngine Oilº in the Index.

6-24
Engine Coolant
The cooling system in your vehicle is filled with
DEX
-COOL
engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX
-COOL
extended 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 or if you need to add coolant to your
radiator, see ªEngine Overheatingº in the Index.
A 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant will:

Give freezing protection down to
-34F (-37C).

Give boiling protection up to 265F (129C).

Protect against rust and corrosion.

Help keep the proper engine temperature.

Let the warning lights and gages work as
they should.
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.

Scheduled Maintenance
7-14
100,000 Miles (166 000 km)

Replace spark plugs.
An Emission Control Service.
