2005 SATURN L-SERIES climate control

The recirculation mode can be used with vent, bi-level,
or floor modes, but it cannot be used with the defog
or defrost modes. When you switch to the defog
or defrost modes the system will automatically move
from recirculation to outside air. When you move
the mode knob back to another mode, the system will
move back into recirculation. When the car is turned off
and back on the system will default to outside air
automatically.
AC (Air Conditioning):Press this button to turn the
air-conditioning system on or off. When A/C is pressed,
an indicator light above the button will come on to let
you know that air conditioning is activated.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the recirculation mode.
5. Select the coolest temperature.Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
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 your 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.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and half to the floor outlets with a small
amount directed to the side windows. When you select
this mode, the system turns off recirculation automatically
and runs the air-conditioning compressor unless the
outside temperature is at or below freezing. The
recirculation mode cannot be selected while in the
defog mode. Do not drive the vehicle until all the
windows are clear.

Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment air filter. It is located underneath the hood
just below the windshield wiper arm on the passenger’s
side of the vehicle.
The filter traps most of the pollen from air entering the
Climate Control System. Like your engine’s air
cleaner/filter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
filter, seeScheduled Maintenance on page 6-4.
For the type of filter to use, seeNormal Maintenance
Replacement Parts on page 6-14.
To change the passenger compartment air filter, use the
following steps:
1. Open the hood. Locate the passenger compartment
air filer access panel.
2. Peel back the hood weatherstrip from the
passenger’s side of the vehicle halfway to center.3. Use a tool to open the passenger compartment
air filter access door.
4. Remove any leaves or other debris from the
filter area.

Battery Warning Light
The battery warning light
will come on briefly as a
check, when you turn
on the ignition. Then it
should go out when
the engine is started.
If the light does not come on when you start your
vehicle, have your vehicle serviced right away. This
condition may indicate your battery warning light is not
functioning properly. If this light comes on while you
are driving, be sure to turn off accessories such as the
radio and climate control system. Have your vehicle
serviced right away.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can still
work and stop you. For good braking, though, you
need both parts working well.If the brake system warning light comes on, there is
a brake problem. Have your brake system inspected
right away.
The BRAKE light is
located in the instrument
panel cluster.
This light should come on briefly when you turn the
ignition key to RUN. If it doesn’t come on then, have it
fixed so it will be ready to warn you if there’s a
problem.
When the ignition is on, the BRAKE light will come on
when you set your parking brake. The light will stay on if
your parking brake doesn’t release fully. A chime will
also sound if the parking brake is not fully released and
the vehicle is moving. If it stays on after your parking
brake is fully released, it means you have a brake
problem.
The BRAKE light will also come on to indicate a low
brake fluid level. SeeBrakes on page 5-33for
more information.

Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance.
(This applies only to vehicles sold in the United States.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to 30 cm), or to some limited-production tires.
While the tires available on Saturn passenger cars and
light trucks may vary with respect to these grades,
they must also conform to federal safety requirements
and additional General Motors Tire Performance
Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
