Engine Coolant Temperature Gage
This gage on the left
measures the temperature
of the vehicle’s engine
coolant. If the pointer
moves into the shaded
area, your engine is
too hot!
If the engine coolant temperature reaches 253° (123°C)
the CHK GAGE message will appear and a chime
will sound to alert you to the engine coolant temperature
gage. SeeMessage Center on page 3-39. If you have
been operating your vehicle under normal driving
conditions, you should pull off the road and stop your
vehicle, be sure the air conditioning is off, let the engine
idle for a few minutes, then turn off the engine.
If your engine control system detects a failure in the
engine coolant temperature circuit, the malfunction
indicator lamp (service engine soon) light will come on.
The coolant gage may read all the way hot or cold.The engine cooling fan will be turned on to protect the
engine and transmission. SeeMalfunction Indicator
Lamp on page 3-33for more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (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.

Fuel Gage
When the ignition is on,
the fuel gage on the right
tells you about how
much fuel you have left in
your tank.
When the indicator nears empty, the LOW FUEL
message will come on. You still have a little fuel left, but
you should get more soon. SeeLow Fuel Warning
Message on page 3-43for more information.Here are four things that some owners ask about. None
of these show a problem with your fuel gage:At the service station, the fuel pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to
ll the tank.
The gage moves a little when you turn a corner or
speed up.
The gage takes a few seconds to stabilize after the
ignition is turned on, and will go back to empty
when you turn the ignition off.
For your fuel tank capacity, seeCapacities and
Speci cations on page 5-100.

Notice:Your vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in your fuel
system and also damage the plastic and rubber
parts. That damage would not be covered under
your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing additive
called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you buy
gasoline whether the fuel contains MMT. General Motors
does not recommend the use of such gasolines.
Fuels containing MMT can reduce the life of spark plugs
and the performance of the emission control system
may be affected. The malfunction indicator lamp
may turn on. If this occurs, return to your authorized
Saturn retailer for service.Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to nd. Never use leaded gasoline or any other fuel
not recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel would not
be covered by your warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you will be driving.

Brake Wear
Your vehicle has front disc brakes and may have rear
drum brakes or rear disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads
are worn and new pads are needed. The sound
may come and go or be heard all the time your vehicle
is moving, except when you are pushing on the
brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon your brakes will not work well. That
could lead to an accident. When you hear the
brake wear warning sound, have your vehicle
serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are rst applied or lightly
applied. This does not mean something is wrong with
your brakes.Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to Saturn speci cations.
The rear drum brakes do not have wear indicators, but
if you ever hear a rear brake rubbing noise, have
the rear brake linings inspected immediately. Also, the
rear brake drums should be removed and inspected
each time the tires are removed for rotation or changing.
When you have the front brake pads replaced, have
the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.Brake Pedal Travel
See your retailer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop, your
brakes adjust for wear. If you rarely make a moderate
or heavier stop, then your brakes might not adjust
correctly. If you drive in that way, then — very
carefully — make a few moderate brake stops about
every 1,000 miles (1 600 km), so your brakes will adjust
properly.
