ENGINE
I
United States

Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called
OBD I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The CHECK
ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent.
This may prevent more
serious damage to your vehicle.
This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
I NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be
as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.

Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel. See “Engine Coolant
Temperature Gage” in the Index. You will also find a
LOW COOLANT level warning light on your vehicle’s
instrument panel. See “Low Coolant Warning Light” in
the Index.
If Steam Is Coming From Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn
it off and get everyone away
from the vehicle until
it cools down. Wait until
there is no sign
of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine
if
it overheats, and get out of the vehicle until the
engine
is cool.
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered
by your warranty.

L AUTION
-
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t do anything else until it cools down.
The coolant level should be at or above FULL COLD.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump
or somewhere else in
the cooling system.
5-18

, ,- CAUTION:
~ Heater and radiator hoses, and other engine
1 parts, can be very hot. Don’t touch them. If you
l do, you can be burned.
Don’t run the engine
if there is a leak. If you run
1 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.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fan is running.
If the
engine is overheating, the fan should be running.
If it
isn’t, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL@ coolant at
the coolant surge tank, but be sure the cooling system,
including the coolant surge
tank pressure cap, is cool
before you do it. (See “Engine Coolant” in the Index
for more information.)
5-19

3. Then fill the coolant surge tank with the proper
mixture, up
to FULL COLD, or just above the small
cylinder at the base
of the opening.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower.
If the level is lower, add
more
of the proper mixture to the coolant surge tank
until the level reaches
FULL COLD, or just above
the small cylinder at the base of the opening.

5. Then replace the pressure cap. Be sure the pressure
Check the level in the surge tank when the cooling
system has cooled down. If the coolant isn’t at the
proper level, repeat Steps

is tight.
If a Tire Goes Flat
It’s
unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If
air goes
out of a tire, it’s much more likely to leak out slowly.
But
if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck hnnel, add enough fluid at the
dipstick hole to bring
it to the proper level.
3. After adding fluid, recheck the fluid level as
described under “How to Check.”
4. When the correct fluid level is obtained, push
the dipstick back in all the way.
Engine Coolant
The cooling s stem 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.

Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little -- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the
FULL COLD mark.

engine coolant.
Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture at the surge tank, but only when the
engine
is cool.
A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn
if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
When replacing the pressure cap, make sure it is tight.

Part B: Owner Checks and Services
Listed below are owner checks and services which should be performed at the intervals specified to help
ensure the safety, dependability and emission control
performance of your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any fluids
or lubricants are added to your
vehicle, make sure they are the proper ones, as shown in
Part D.
At Each Fuel Fill
It is important for you or a service station attendant to
per$orm these underhood checks at each fuel
fill.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. See “Engine Oil” in the Index for
further details.
Engine Coolant Level Check
Check the engine coolant level and add DEX-COOL@
coolant mixture if necessary. See “Engine Coolant” in
the Index for further details.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the
windshield washer tank and add the proper fluid
if
necessary. See “Windshield Washer Fluid” in the Index
for further details.
At Least Once a Month
Tire Inflation Check
Make sure tires are inflated to the correct pressures. See
“Tires”
in the Index for further details.
Cassette Deck Service
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See “Audio Systems” in the
Index for further details.
