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.

2-47
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.

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot!
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull of the road, stop your
vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.

2-110 Traction Active Message (Option)
United States Canada
If your vehicle has the traction control system, the
TRACTION ACTIVE message will appear when the
traction control system is limiting wheel spin. You may
feel or hear the system working, but this is normal.
Slippery road conditions may exist if this message
appears, so adjust your driving accordingly. The
message will stay on for a few seconds after the traction
control system stops limiting wheel spin.
Engine Coolant Temperature
Warning Message
United States Canada
This message will come on when your engine
gets too hot.
If this message comes on, 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.

3-4 Heating
Turn the temperature knob clockwise (toward the red
area) to warm the air.
In the LOWER setting, 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, turn 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 you have the optional engine coolant heater and 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
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.

Engine Overheating
You will find an engine coolant temperature gage on
the instrument panel cluster. See ªEngine Coolant
Temperature Gageº in the Index. You also have an
engine coolant temperature warning message on the
instrument panel cluster. See ªEngine Coolant
Temperature Warning Messageº 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.
Should an overheated engine condition exist, 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 temperature gage will indicate an
overheat condition exists. 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 and change the oil.
See ªEngine Oilº in the Index.

6-23
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, 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 messages 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.

Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer's instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
The windshield washer fluid
reservoir is located on the
passenger's side of the
engine compartment, near
the fuse and relay center.
See ªEngine Compartment
Overviewº in the Index
for more information
on location.Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the tank is full.
NOTICE:

When using concentrated washer fluid,
follow the manufacturer's instructions for
adding water.

Don't mix water with ready
-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn't clean as well as washer fluid.

Fill your washer fluid tank only
three
-quarters full when it's very cold. This
allows for expansion if freezing occurs,
which could damage the tank if it is
completely full.

Don't use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.
