Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order
to help your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed to
evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and
your vehicle still does not pass the inspection for
lack of OBD system readiness, your retailer
can prepare the vehicle for inspection.
Oil Pressure Light
If you have a low engine
oil pressure problem,
this light will stay on after
you start your engine, or
come on when you are
driving.
This indicates that your engine is not receiving
enough oil.
The engine could be low on oil, or could have
some other oil problem. Have it xed immediately.

The oil light may also come on when the ignition
is on but the engine is not running, the light
will come on as a test to show you it is working,
but the light will go out when you turn the
ignition to START. If it does not come on with the
ignition on, you may have a problem with the
fuse or bulb. Have it xed right away.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others could
be burned. Check your oil as soon as
possible and have your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
Passlock®Warning Light
Your vehicle has a
Passlock®
theft-deterrent system.
With this system, the
security light will ash as
you open the door if your
ignition is off.
For more information, seePasslock
®on page 103.
Reduced Engine Power Light
This light will come on
briey when you start
the engine.
This light, along with the service engine soon light
will be displayed when a noticeable reduction in
the vehicle’s performance may occur. Stop the
vehicle and turn off the ignition. Wait for
10 seconds and restart your vehicle. This may
correct the condition.

The vehicle may be driven at a reduced speed
when the reduced engine power light is on
but acceleration and speed may be reduced.
The performance may be reduced until the next
time you drive your vehicle. If this light stays
on, see your retailer as soon as possible
for diagnosis and repair.
Highbeam On Light
This light comes on
when the high-beam
headlamps are in use.
SeeHeadlamp High/Low-Beam Changer on
page 145.
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 185for more
information.

If your vehicle has this gage, it is located on the
steering column.
This gage indicates vacuum during light to
moderate throttle and boost under heavier throttle.
This gage displays the air pressure level in the
intake manifold before it enters the engine’s
combustion chamber.This gage is automatically centered at zero every
time the ignition is turned to RUN. Actual
vacuum or boost is displayed from this zero point.
The boost gage has three pairs of lights that
are located on each side of the gage. These lights
are used to indicate three different engine rpm
levels. The default setting for the lower pair
of lights is 4,400 rpm, the middle pair of lights is
5,600 rpm, and the top pair of lights is 6,200 rpm.
These settings can be adjusted by turning the
stem behind each light. To have the light
pair come on at a higher rpm level, turn the stem
counterclockwise. To have the light pair come
on at a lower rpm level, turn the stem clockwise.
Each detent adjusts the settings by 100 rpm.
To restore the default settings, press and hold any
stem for three seconds. The lights will ash
three times.
To turn the lights off or on, press and release
any stem.

player, CB radio, mobile telephone, or two-way
radio, make sure that it can be added by
checking with your dealer/retailer. Also, check
federal rules covering mobile radio and
telephone units. If sound equipment can be
added, it is very important to do it properly.
Added sound equipment may interfere with the
operation of your vehicle’s engine, radio, or
other systems, and even damage them. Your
vehicle’s systems may interfere with the
operation of sound equipment that has
been added.
Your vehicle has a feature called Retained
Accessory Power (RAP). With RAP, the audio
system can be played even after the ignition
is turned off. SeeRetained Accessory
Power (RAP) on page 108for more information.Setting the Time (Without Date

Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic.
This is a mistake. The brakes may not have time to
cool between hard stops. The brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic
following distances, you will eliminate a lot of
unnecessary braking. That means better braking
and longer brake life.
If your vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the engine stops, you will still have
some power brake assist. But you will use it
when you brake. Once the power assist is used
up, it may take longer to stop and the brake pedal
will be harder to push.
Adding non-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 270.Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel will
come on briey
when you start your
vehicle.
When you start your engine, or when you begin to
drive away, your ABS will check itself. You may
hear a momentary motor or clicking noise
while this test is going on, and you may even
notice that your brake pedal moves or pulses a
little. This is normal.

Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction
System (ETS) that limits wheel spin. This is
especially useful in slippery road conditions. The
system operates only if it senses that one or
both of the front wheels are spinning or beginning
to lose traction. When this happens, the system
reduces engine power and may also upshift
the transaxle to limit wheel spin.
The LOW TRAC message will be displayed when
your ETS is engaged and limiting wheel spin.
SeeLow Traction Message on page 182. You may
feel or hear the system working, but this is normal.
If your vehicle is in cruise control when the ETS
begins to limit wheel spin, the cruise control
will automatically disengage. When road conditions
allow you to safely use it again, you may
re-engage the cruise control. SeeCruise Control
on page 147.
The ETS operates in all transaxle shift lever
positions. But the system can upshift the transaxle
only as high as the shift lever position you have
chosen, so you should use the lower gears
only when necessary.The ETS automatically comes on whenever you
start your vehicle. The light on the traction control
button will also come on to let you know the
system is on. To limit wheel spin, especially in
slippery road conditions, you should always leave
the system on. But you can turn the traction
control system off if you ever need to. You should
turn the system off if your vehicle ever gets
stuck in sand, mud or snow and rocking the
vehicle is required. SeeRocking Your Vehicle to
Get It Out on page 250andIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 249.
To turn the system on
or off, press the
enhanced traction
system button located
on the instrument panel.
226
ProCarManuals.com

When you turn the system off, the TRAC OFF
message will be displayed. If the ETS is limiting
wheel spin when you press the button to turn
the system off, the TRAC OFF message will be
displayed, but the system will not turn off until
there is no longer a current need to limit wheel
spin. You can turn the system back on at any time
by pressing the button again. The TRAC OFF
message will no longer be displayed.
Adding non-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 270for more information.
Limited-Slip Differential
Your vehicle may have this feature. A limited-slip
transaxle can give you additional traction on
snow, mud, ice, sand or gravel. It works like a
standard transaxle most of the time, but when one
of the front wheels loses traction, this feature
will allow the wheel with traction to move
the vehicle.
Steering
Electric Power Steering
If the engine stalls while you are driving, the
power steering assist system will continue
to operate until you are able to stop the vehicle.
If you lose power steering assist because the
system is not functioning, you can steer but it will
take much more effort.
If you turn the steering wheel in either direction
several times until it stops, or hold the steering
wheel in the stopped position for an extended
amount of time, you may notice a reduced amount
of power steering assist. The normal amount of
power steering assist should return shortly after a
few normal steering movements.
The electric power steering system does not require
regular maintenance.
If the PWR STR
message in the
message center is
displayed, see your
retailer for service.
SeePower Steering
Message on page 184.
