Cadillac 2009 CTS-V Automobile User Manual


 
To replace the passenger compartment air filter:
1. Turn the ignition to ON/RUN with the engine off.
2. Turn on the windshield wipers and turn the ignition
off again when the wipers are straight up on the
windshield.
This allows access to the leaf screen.
The passenger compartment air filter is
located under the screen.
3. Open the hood to access the engine compartment.
See Hood Release on page 5-13 for more
information.
4. Remove the three screws that hold the screen in
place and lift off the screen by lifting and sliding it
toward the center of the vehicle.
5. Pull out on the two tabs located on each end of the
filter cover.
6. Lift the filter cover off by pulling it straight up.
7. Remove the old filter and insert a new one.
See Maintenance Replacement Parts on page 6-16
for the correct part number for the filter.
8. Reverse Steps 1 through 6 to reinstall the cover.
Warning Lights, Gages, and
Indicators
Warning lights and gages 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 gages could prevent injury.
Warning lights come on when there may be or 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.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages 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 gages shows there
may 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.
