In many crashes severe enough to inate an
airbag, windshields are broken by vehicle
deformation. Additional windshield breakage may
also occur from the right front passenger
airbag.
Airbags are designed to inate only once.
After an airbag inates, you will need
some new parts for the airbag system. If you
do not get them, the airbag system will
not be there to help protect you in another
crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to
replace other parts.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection and
Event Data Recorders on page 418.
Let only qualied technicians work on the
airbag system. Improper service can mean that
the airbag system will not work properly.
See your retailer for service.
Passenger Sensing System
If your vehicle has one of the indicators pictured in
the following illustrations, then your vehicle has
a passenger sensing system. The passenger
airbag status indicator on the instrument panel will
be visible when you turn your ignition key to
RUN or START.
The words ON and OFF or the symbol for on and
off, will be visible during the system check.
When the system check is complete, either the
word ON or the word OFF, or the symbol for on or
the symbol for off will be visible. SeePassenger
Airbag Status Indicator on page 168.
The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.

A thick layer of additional material such as a
blanket, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers,
can affect how well the passenger sensing system
operates. Remove any additional material from
the seat cushion before reinstalling or securing the
child restraint and before a small occupant,
including a small adult, sits in the right front
passenger position. You may want to consider not
using seat covers or other aftermarket equipment
if your vehicle has the passenger sensing
system. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 83for more
information about modications that can affect how
the system operates.
The passenger sensing system may suppress the
airbag deployment when liquid is soaked into
the seat. If this happens, the off indicator in the
passenger airbag status indicator and the
airbag readiness light on the instrument panel will
be lit. The system should resume normal
operation after the seat is allowed to dry. If the
system operates incorrectly after the seat
has dried, have your retailer check the system.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system in
several places around your vehicle. You do
not want the system to inate while someone is
working on your vehicle. Your retailer and the
service manual have information about servicing
your vehicle and the airbag system. To purchase a
service manual, seeService Publications
Ordering Information on page 425.

{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 77for more on this,
including important safety information.If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your retailer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 167.

Engine Coolant Temperature Gage
This gage measures the
temperature of the
vehicle’s engine coolant.
If the pointer moves into the shaded area, your
engine is too hot, the CHK GAGE message
will appear and a chime will sound to alert you to
the engine coolant temperature gage. See
Check Gage Message on page 184for more
information. 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.On vehicles with the 2.2L engine, under severe
conditions – hot ambient temperature, steep
grades and towing – your vehicle may experience
more transaxle shifting to avoid engine coolant
overheating. This is temporary and normal under
these conditions. This does not require engine
or transaxle service.
If your engine control system detects a failure in
the engine coolant temperature circuit, the
malfunction indicator lamp 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 transaxle. SeeMalfunction
Indicator Lamp on page 174for more information.
Notice:Driving with the engine coolant
temperature gage indicator in the shaded area
could cause your vehicle to overheat. Your
vehicle could be damaged, and it might not be
covered by your warranty. Never drive with
the engine coolant temperature gage indicator
in the shaded area.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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.Notice:If you keep driving your vehicle with
this light on, after awhile, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead
to costly repairs that might not be covered by
your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 270.

If your vehicle has the 2.4L L4 engine (VIN Code B)
or the 2.0L Supercharged engine (VIN Code P), use
premium unleaded gasoline with a posted octane
rating of 91 or higher. You may also use regular
unleaded gasoline rated at 87 octane or higher, but
your vehicle’s acceleration may be slightly reduced,
and you may notice a slight audible knocking noise,
commonly referred to as spark knock. If the octane
is less than 87, you may notice a heavy knocking
noise when you drive. If this occurs, use a gasoline
rated at 87 octane or higher as soon as possible.
Otherwise, you might damage your engine. If you
are using gasoline rated at 87 octane or higher and
you hear heavy knocking, your engine needs
service.
Gasoline Specications
At a minimum, gasoline should meet ASTM
specication D 4814 in the United States or
CAN/CGSB-3.5 in Canada. Some gasolines may
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT). Saturn recommends against the use
of gasolines containing MMT. SeeAdditives on
page 273for additional information.
California Fuel
If your vehicle is certied to meet California
Emissions Standards, it is designed to operate on
fuels that meet California specications. See the
underhood emission control label. If this fuel is not
available in states adopting California emissions
standards, your vehicle will operate satisfactorily on
fuels meeting federal specications, but emission
control system performance may be affected. The
malfunction indicator lamp may turn on and your
vehicle may fail a smog-check test. SeeMalfunction
Indicator Lamp on page 174. If this occurs, return to
your authorized Saturn retailer for diagnosis. If it is
determined that the condition is caused by the type
of fuel used, repairs may not be covered by your
warranty.
Additives
To provide cleaner air, all gasolines in the United
States are now required to contain additives
that will help prevent engine and fuel system
deposits from forming, allowing your emission
control system to work properly. In most cases,
you should not have to add anything to your fuel.
273
ProCarManuals.com

Page 274 of 440

However, some gasolines contain only the
minimum amount of additive required to meet
U.S. Environmental Protection Agency regulations.
To help keep fuel injectors and intake valves
clean, or if your vehicle experiences problems due
to dirty injectors or valves, look for gasoline that
is advertised as TOP TIER Detergent Gasoline.
Also, your retailer has additives that will help
correct and prevent most deposit-related problems.
Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gasolines
may be available in your area. We recommend that
you use these gasolines if they comply with the
specications described earlier. However,
E85 (85% ethanol) and other fuels containing
more than 10% ethanol must not be used
in vehicles that were not designed for those fuels.
Notice:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in the fuel system and also damage
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.
We recommend against 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 retailer for service.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel might 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 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 the 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
specications.
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.
