Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. SeeScheduled Maintenance on
page 6-4for more information. Things that are especially
important in trailer operation are automatic transaxle
uid (don’t overll), engine oil, axle lubricant, drive belt,
cooling system and brake system. Each of these is
covered in this manual, and the Index will help you nd
them quickly. If you’re trailering, it’s a good idea to
review this information before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating
on page 5-30.

Automatic Transaxle Fluid
(2.2L L4 Engine)
When to Check and Change
Automatic Transaxle Fluid
A good time to check your automatic transaxle uid
level is when the engine oil is changed.
Change the uid at the intervals listed inAdditional
Required Services on page 6-6, and be sure to use
the transaxle uid listed inRecommended Fluids
and Lubricants on page 6-14.
How to Check Automatic
Transaxle Fluid
If your vehicle is equipped with the 2.2L L4 engine,
you will have to have this procedure done at your
retailer’s service department.
Notice:Use of the incorrect automatic transaxle
uid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transaxle uid listed in
Recommended Fluids and Lubricants on page 6-14.
Automatic Transaxle Fluid
(3.5L V6 Engine)
When to Check and Change
Automatic Transaxle Fluid
A good time to check your automatic transaxle uid
level is when the engine oil is changed.
Change the uid at the intervals listed inAdditional
Required Services on page 6-6, and be sure to use
the transaxle uid listed inRecommended Fluids
and Lubricants on page 6-14.
How to Check Automatic
Transaxle Fluid
Because this operation can be a little difficult, you may
choose to have this done at your retailer’s service
department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
Notice:Too much or too little uid can damage the
transaxle. Too much can mean that some of the uid
could come out and fall on hot engine or exhaust
system parts, starting a re. Too little uid could
cause the transaxle to overheat. Be sure to get an
accurate reading if you check the transaxle uid.

Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The hydraulic clutch system does not
have its own reservoir. The system receives uid from
the brake master cylinder reservoir. It is lled with
DOT-3 brake uid. SeeBrakes on page 5-38for
more information.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 100,000 miles
(166 000 km), whichever occurs rst, 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, seeEngine Overheating
on page 5-30.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:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
5-27
ProCarManuals.com

What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL®coolant which will not damage
aluminum parts. If you use this coolant mixture, you
do not need to add anything else.
{CAUTION:
Adding 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 would not get the overheat warning.
Your engine could catch re 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 would not 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 retailer check your cooling system.
Notice:If you use extra inhibitors and/or additives
in your vehicle’s cooling system, you could
damage your vehicle. Use only the proper mixture
of the engine coolant listed in this manual for
the cooling system. SeeRecommended Fluids and
Lubricants on page 6-14for more information.

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. SeeEngine Overheating on page 5-30
for instructions on “How to Add Coolant to the Coolant
Surge Tank.”
{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. Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
If you need to replace your coolant surge tank pressure
cap, see your retailer.
Engine Overheating
You will nd a coolant temperature gage and a coolant
temperature warning light on your vehicle’s instrument
panel. SeeEngine Coolant Temperature Gage on
page 3-36andEngine Coolant Temperature Warning
Light on page 3-35.

If Steam Is Coming From Your Engine
{CAUTION:
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 re.
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 re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not
be covered by your warranty.
If No Steam Is Coming From
Your Engine
If you get an engine overheat warning, but see or
hear no steam, the problem may not be too serious.
Sometimes the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. If you have an air conditioner and it is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.
3. Try to minimize engine load. If you are in a traffic
jam, shift to NEUTRAL (N); otherwise, shift to the
highest gear possible while driving.

If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about ten minutes.
If the warning does not 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.
If there is still no sign of steam, you can idle the engine
for three minutes while you are 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 is safe to lift the hood, here is what
you will see:
A. Electric Engine Fan
B. Coolant Surge Tank with Pressure Cap
