Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate
control system is used properly. There are two
modes to choose from to clear fog or frost from the
windshield. Use the defog mode to clear the
windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog
or frost from the windshield more quickly.
-(Defog):Turn the mode knob to this position
to select the defog setting, which delivers air to the
oor and windshield outlets. Use this setting to
clear the windows of fog or moisture.
0(Defrost):Turn the mode knob to this position
to defrost the windshield. The system automatically
controls the fan speed if defrost is selected from
the AUTO mode. If the outside temperature is 40°F
(4°C) or warmer, the air conditioning compressor
automatically runs to help dehumidify the air
and dry the windshield. The air conditioning
indicator light blinks three times if the compressor
is turned off while in this mode.
The engine will not perform Auto Stops when the
defrost mode is on.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press this button to turn the rear
window defogger on or off. An indicator light above
the button comes on to show that the rear
window defogger is activated.
If driving below 50 mph (80 km/h), the rear window
defogger turns off about 15 minutes after the
button is pressed. If additional warming time is
needed, press the button again.
If the vehicle’s speed is maintained above 50 mph
(80 km/h), the rear window defogger remains
on once the button is pressed.
If your vehicle has heated outside mirrors, the
surface of the outside mirrors also heat when the
rear window defogger is activated. SeeOutside
Power Mirrors on page 126.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.

Outlet Adjustment
There are four main air outlets on the instrument
panel. Use the lever located in the center of
each outlet by moving it either side-to-side or up
and down, to change the direction and amount
of airow in the vehicle. The center thumbwheel
does not control the main outlets.
Dedicated Rear Seat Air Outlet
For vehicles with this feature, the dedicated rear
seat air outlet is located in the center of the
instrument panel above the two main center
outlets. This outlet is aimed to provide comfort to
the rear seat passengers, especially while
using air conditioning in warm weather.
Use the thumbwheel in the center of the outlet to
turn the airow on or off. This can be adjusted
to improve front seat passenger comfort if
there are no rear seat passengers. The direction
of airow cannot be adjusted since it is directed
towards the rear seat passengers.
Do not attempt to move the horizontal vent vane,
as breakage can occur.
Operation Tips
Clear away any ice, snow, or leaves from the
air inlets at the base of the windshield that
can block the ow of air into your vehicle.
Do not use non-GM approved hood deectors
as they could adversely affect the performance
of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside of
your vehicle more effectively.
When an objectionable odor outside the
vehicle is encountered, use the recirculation
mode, with the temperature knob at a
comfortable setting to prevent the odor from
entering the vehicle through the ventilation
system. This can be helpful when driving
through a long tunnel with poor ventilation.
However, extended usage of this mode in cold
or cool weather can cause window fogging.

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 and seat-mounted
side impact 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 airbags. SeeAirbag
Readiness Light on page 164.
Charging System Light
The charging system
light will come on for a
few seconds when
you turn on the ignition
as a check to indicate
it is working.
If the light stays on, or comes on while you are
driving and you hear a chime, there could be
a problem with the electrical charging system. This
could indicate that there is a loose generator
drive belt or another electrical problem. Have it
checked right away. Driving while this light
is on could drain the battery and result in the
engine and headlights suddenly shutting off.
If you must drive a short distance with this light
on, turn off accessories, such as the radio,
air conditioner and heater fan.

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and could damage the emission
control system on your vehicle. Diagnosis and
service might be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service might be
required.
If the Light is Flashing
The following can prevent more serious damage
to your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
the vehicle. Turn the key off, wait at least
10 seconds, and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps and see your dealer/retailer
for service as soon as possible.
If the Light Is On Steady
You might be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 258.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed. A
loose or missing fuel cap allows fuel to evaporate
into the atmosphere. A few driving trips with
the cap properly installed should turn the light off.

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 172. 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.
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.

Brake Wear
Your vehicle has 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
can 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 can cause a
brake squeal when the brakes are rst applied
or lightly applied. This does not mean something
is wrong with the 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 torque
specications inCapacities and Specications on
page 351.
Brake linings should always be replaced as
complete axle sets.Brake Pedal Travel
See your dealer/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
that brake service might be required.
Brake Adjustment
Every time you apply the brakes, with or without
the vehicle moving, the brakes adjust for wear.
