Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment air filter. There are two types of filters
available. There is a standard dust filter that traps small
particles including pollen. There is, also, a dust/odor
filter available that traps dust and pollen and uses a
charcoal element to help reduce many offensive odors
from entering your vehicle. The filter will need to be
changed periodically. For information on when to
change the passenger compartment air filter, see
Scheduled Maintenance on page 7‑3.
Notice:Driving without a passenger compartment
air filter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the old
filter with a new one.
The access panel for the passenger compartment air
filter is located under the hood near the windshield,
on the passenger side of the vehicle. See Engine
Compartment Overview
on page 6‑13for more
information on location. See Doing Your Own Service
Work
on page 6‑5for information on doing your own
service work.
To access the passenger compartment air filter:
1. Pull back the rubber hood seal from the edge of the leaf screen vent cover.
2. Remove the three fasteners that hold the filter cover in place and slide the cover off.
3. To access the filter, remove the water deflector by lifting the outboard edge of the deflector to release
the retention tab.
4-50

Black plate (51,1)Cadillac STS Owner Manual - 2011
4. Lift the inboard edge of the deflector to release theretention tab.
5. Lift and slide the water deflector toward the inboard side and remove it.
6. The top edge of the filter should be visible. Reachin and lift the filter out , pulling upward and toward
the front of the vehicle.
7. Insert the new air filter by sliding it back into place. Make sure the arrow on the filter is pointing toward
the passenger compartment.
Reverse steps 1 through 3 to reinstall the water
deflector, filter cover and the hood seal.
Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gauges could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle's functions. Some
warning lights come on briefly when the engine is
started to indicate they are working.
Gauges can indicate when there might be or there
is a problem with one of the vehicle's functions. Often
gauges and warning lights work together to indicate a
problem with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gauges shows there
could be a problem, check the section that explains
what to do. Follow this manual's advice. Waiting to do
repairs can be costly and even dangerous.

the front. See Engine Compartment Overview
on
page 6‑13for more information on locating the air
cleaner/filter.
6-21

Black plate (22,1)Cadillac STS Owner Manual - 2011
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the scheduled
maintenance intervals and replace it at the first oil
change after each 80 000 km (50,000 mile) interval. See
Scheduled Maintenance
on page 7‑3for more
information. If you are driving in dusty/dirty conditions,
inspect the filter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter remove the filter from the
vehicle and lightly shake the filter to release loose dust
and dirt. If the filter remains caked with dirt, a new filter
is required.
To inspect or replace the filter:
1. Remove the two screws located on the top of the cover.
2. Disconnect the coolant recovery hose so that it is not going across the top of the engine air cleaner/
filter.
3. Loosen the clamp and remove the duct from the passenger's side of the engine air cleaner/filter. 4. The two sides of the airbox are hinged at the
bottom. Open the airbox by pushing the top of the
airbox cover toward the engine.
5. Remove the air filter by lifting it straight up through the opening in the airbox.
6. Inspect or replace the engine air cleaner/filter. See Maintenance Replacement Parts
on page 7‑11for
the correct part number for the filter.
7. Reinstall the cover by reversing Steps 1 through 4.
{WARNING:
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. Use caution when
working on the engine and do not drive with the
air cleaner/filter off.
Notice: If the air cleaner/filter is off, dirt can easily
get into the engine, which could damage it. Always
have the air cleaner/filter in place when you are
driving.

Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take the vehicle to the dealer
service department and have it repaired as soon as
possible.
The vehicle is not equipped with a transmission fluid
level dipstick. There is a special procedure for checking
and changing the transmission fluid. Because this
procedure is difficult, it should be done at the dealer
service department. Contact the dealer for additionalinformation or the procedure can be found in the service
manual. To purchase a service manual, see
Service
Publications Ordering Information on page 8‑17.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7‑9.
Change the fluid and filter at the intervals listed in
Scheduled Maintenance
on page 7‑3, and be sure
to use the fluid listed in Recommended Fluids and
Lubricants on page 7‑9.
