When starting your engine in very cold weather (below
0°F or -18"C), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up to
15 seconds. When the engine starts, let go of
the key.
2. 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. When the engine
starts, let go
of the key and accelerator. 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.
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
Your vehicle may have this feature. 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 (OOC), use of the coolant heater
is not
required.
2-20

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the driver’s side of the engine
compartment, behind the battery.
3. Plug it into a normal, grounded 1 IO-Volt AC outlet.
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
CAUTION: (Continued) three-prong 110-volt
AC
o-.-.et. If the cc. -
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.

connect with the wheels. To restart when you’re already
moving, use N ITRAL

“racing” (running at high speed) is dangerous.
Unless your foot is firmly on the brake pedal,
your vehicle could move very rapidly. You
could lose control and hit people or objects.
Don’t shift into a drive gear while your engine
is racing.
Nofice: Damage to your transmission caused by
shifting out
of PARK (P) or NEUTRAL (N) with
the engine racing isn’t covered by your warranty.
On cold days, approximately 32°F (OOC) or colder, your
transmission is designed
to shift differently until the
engine reaches normal operating temperature. This is
intended
to improve heater performance.
DRIVE (D): This position is for normal driving. If you
need more power for passing, and you’re:

You can also use SECOND (2) for starting the vehicle
from a stop on slippery road surfaces.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
Press this button
to turn
the rear window defogger
on or
off
An indicator light in the button will come on to let you
know that the rear window defogger is activated.
The rear window defogger will turn
off approximately 10
minutes after the button is pressed. If you need
additional warming time, press the button again.
Notice: Don’t use a razor blade or something else
sharp on the inside
of the rear window. If you
do, you could cut or damage the defogger and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape, a
decal or anything similar to the defogger grid.
Do not attach a temporary vehicle license, tape, a decal
or anything similar
to the defogger grid.
Outlet Adjustment
Use the air outlets located in the center and on the side
of your instrument panel
to direct the airflow.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the vent setting
to direct outside
air through your vehicle.
Your vehicle’s ventilation system supplies outside air
to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air inlet
grilles, through the vehicle and out the air exhaust
valves.
Outside air will also enter the vehicle when the heater
or the air conditioning compressor is running, unless you
have the recirculation button pushed in.
3-24

Operation Tips
e
e
e
Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such
as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the
fan knob all the way
to the right for a few moments
before driving. This helps clear the intake ducts
of snow and moisture, and reduces the chance of
fogging the inside of your window.
Keep the air path under the front seats clear of
objects. This helps air
to circulate throughout
your vehicle.
Adding outside equipment
to the front of your
vehicle, such as hood-air deflectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment
to the outside of your vehicle.
Rear Climate Control System
The lower buttons on the rear seat audio are used to
adjust the rear seat comfort controls. The temperature of
the air coming through the rear outlets is determined
by the front passenger’s temperature setting. The button
with the up and down arrows on
it regulates the fan
speed. The mode button is used
to change the direction
of airflow (upper, bi-level or floor) to the rear seat
area. To turn the rear comfort controls off, press the
lower
PWR button.

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. Snow can trap ~,,raust
,,ses u..,er 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.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid
to use. See Part D:
Recommended Fluids and Lubricants on page 6- 17.
Add fluid only after checking the transmission fluid while
it is hot.
(A cold check is used only as a reference.) If
the fluid level is low, add only enough of the proper fluid
to bring the level up
to the HOT area for a hot check.
It doesn’t take much fluid, generally less than one
pint (0.5 L).
Don’t overfill.
Notice: We recommend you use only fluid labeled
DEXRON@
-111, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON@
-111 is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How
to Check”.
When the correct fluid level is obtained, push the
dipstick back
in all the way; then flip the handle
down
to lock the dipstick in place.
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
Engine Overheating on
page 5-24.
A 50/50 mixture of clean, drinkable water and
DEX-COOL@ coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
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.
5-22

What to Use
Use a mixture of one-half clean, drinkable water and
one-half
DEX-COOLB coolant which won’t damage
aluminum parts.
If you use this coolant mixture,
you don’t need
to add anything else.
Ac,,ng only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture.
With plain water or the
wrong mixture, your engine could get too hot
but you wouldn’t get the overheat warning.
Your engine could catch fire and you or others could be burned. Use a
50/50 mixture of clean,
drinkable water and
DEX-COOL@ coolant.
Notice: If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty. Too much water
in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Nofice: If you use the proper coolant, you don’t
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
Checking Coolant
The engine coolant
recovery tank is
in the
engine compartment
on the passenger’s side of
the vehicle. See
Engine
Compartment Overview on
page
5-72 for more
information on location.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be
at FULL
COLD, or a little higher. When your engine is warm, the
level should be at the base of the filler neck or a little
higher.
5-23

If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. In heavy traffic, let the engine idle in neutral while
stopped.
If it is safe to do so, pull off the road, shift
to
PARK (P) or NEUTRAL (N) and let the
engine idle.
speed and open the window as necessary.
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 and you have not stopped, pull
over, stop, and park your vehicle right away.
2. Turn on your heater to full hot at the highest fan
If there’s still no sign of steam, you can push down the
accelerator until the engine speed
is about twice as
fast as normal idle speed for at least 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.
Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it
cools down. The vehicle
should be parked on a level surface.
