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,
but this time keep the pedal down for five or six
seconds. This clears 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.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See ªTowing
Your Vehicleº in the Index.
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.

2-18 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 vehicle's passenger side
headlamp fixture.
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 may have a shift lever on the
steering column or on the console between the seats.
Maximum engine speed is limited on automatic
transaxle vehicles, when you're in PARK (P) or
NEUTRAL (N), to protect driveline components from
improper operation.

2-55 Anti-Lock Brake System Active
Light (Option)
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the anti
-lock brake system
active light will come on.
Slippery road conditions may exist if this light comes
on, so adjust your driving accordingly. The light will
stay on for a few seconds after the system stops
adjusting brake pressure.
The anti
-lock brake system active light also comes on
briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
there to tell you when the system is active.
Engine Coolant Temperature Light
This light tells you that
your engine coolant has
overheated or your
radiator cooling fan(s)
are not working.
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.
In ªProblems on the Road,º this manual shows what to
do. See ªEngine Overheatingº in the Index.

yellowblue
2-56 Engine Coolant Temperature Gage
You have a gage that shows
the engine coolant
temperature. If the gage
pointer moves into the red
area, 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.
In ªProblems on the Road,º this manual shows what to
do. 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.
See ªEngine Coolantº in the Index and have your
vehicle serviced as soon as you can.

3-4 Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the A/C compressor
load, which should help fuel economy.
For quick cool
-down on very hot days, use MAX with
the temperature control all the way in the blue area. 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 A/C with the
temperature control in the blue area. 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. You
can use BI
-LEVEL with the temperature control in the
middle. 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 at others.
Heating
On cold days use FLOOR with the temperature control
all the way in 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'scold 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.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the
red area. To warm passengers while keeping the
windows clean, use DEFOG.
Rear Window Defogger
The rear window defogger
uses a warming grid to
remove fog from the
rear window. Press the area
labeled PUSH to turn the
defogger on.

With current trends in automotive styles and design, it is
essential that the correct towing equipment is used to
tow a vehicle. Your vehicle can be towed with wheel
-lift
or car
-carrier equipment. Additional ramping may be
required for car
-carrier equipment. Use safety chains
and wheel straps. Use the T
-slots for car-carrier
securing. To help avoid damage, install a towing dolly
for either front or rear towing and raise the vehicle until
adequate clearance is obtained between the ground
and/or the wheel
-lift equipment. Do not attach winch
cables or J
-hooks to suspension components when using
car
-carrier equipment. Always use T-hooks inserted into
the T
-hook slots.
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº in the Index.
Engine Overheating
You will find a coolant temperature gage and a warning
light about a hot engine on your instrument panel. See
ªEngine Coolant Temperature Gageº and ªEngine
Coolant Temperature Warning Lightº in the Index. You
also have a LOW COOLANT light on your instrument
panel. See ªLow Coolant Warning Lightº in the Index.
Overheated Engine Protection Operating
Mode (3100 V6 Engine Only)
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 three 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. 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.
