Maintenance When Trailer Towing
Your vehicle will need service more often when
you are pulling a trailer. SeeScheduled
Maintenance on page 391for 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 are 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 297.
Changing a Tire When Trailer Towing
If you get a at tire while towing a trailer, be
sure to secure the trailer and disconnect it from
the vehicle before changing the tire.

Manual Transaxle Fluid
It is not necessary to check the transaxle uid level.
A transaxle uid leak is the only reason for uid
loss. If a leak occurs, take the vehicle to your
retailer’s service department and have it repaired
as soon as possible. SeeRecommended Fluids
and Lubricants on page 402for the proper uid
to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives uid from the brake master
cylinder reservoir.
SeeBrakes on page 308for 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
150,000 miles (240 000 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 297.
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.

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 replace your coolant surge tank pressure
cap, a Saturn cap is required.
Engine Overheating
You will nd a coolant temperature gage on your
vehicle’s instrument panel. SeeEngine Coolant
Temperature Gage on page 173for more
information.You also have a check gage message and a
transaxle uid hot message. SeeCheck Gage
Message on page 184andTransaxle Fluid
Hot Message on page 183.
Notice:Driving with the CHK GAGE message
displayed in the message center and the
Engine Coolant Temperature Gage on your
instrument panel in the red zone could cause
your vehicle to overheat. Your vehicle could
be damaged and the damages might not
be covered by your warranty.

{CAUTION:
Heater and radiator hoses, and other
engine parts, can be very hot. Do not
touch them. If you do, you can be burned.
Do not run the engine if there is a leak.
If you run the engine, it could lose all
coolant. That could cause an engine re,
and you could be burned. Get any leak
xed before you drive the vehicle.
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 is not, your vehicle
needs service. Turn off the engine.Notice:Engine damage from running your
engine without coolant is not covered by
your warranty.
Notice:Using coolant other than DEX-COOL®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant could require changing sooner, at
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.

Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and where
to obtain service, see your Saturn Warranty
booklet for details. For additional information refer
to the tire manufacturer’s booklet included with
your vehicle.
{CAUTION:
Poorly maintained and improperly
used tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out and
a serious accident. SeeLoading Your
Vehicle on page 250.
CAUTION: (Continued)
CAUTION: (Continued)

Underinated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked when
your tires are cold. SeeInflation - Tire
Pressure on page 337.
Overinated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a
pothole. Keep tires at the
recommended pressure.
Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.
SeeHigh-Speed Operation on page 338for
ination pressure adjustment for high
speed driving.
