Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the frontal air bag system. The module records
information about the readiness
of the system,
when the sensors are activated and driver’s safety
belt usage at deployment.
Let only qualified technicians work on your air
bag systems. Improper service
can mean that an
air bag system won’t work properly. See your dealer
for service.
NOTICE:
If you damage the covering for the driver’s or
the right front passenger’s
air bag, or the air
bag covering on the driver’s and right front
passenger’s seatback, the bag may not work
properly. You may have
to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger’s air bag, or both the
air bag
module and seatback for the driver’s and right
front passenger’s side impact air bag.
Do not
open or break the
air bag coverings. Servicing
Your
Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the Catera Service
Manual have information about servicing your vehicle
and the air bag systems.
To purchase a service manual,
see “Service and Owner Publications” in the Index.
I
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still inflate during improper service.
You can be injured if you are close
to an air bag
when it inflates. Avoid wires wrapped with yellow
felt, wires wrapped with yellow tape or yellow
connectors. They are probably part of the air
bag systems. Be sure to follow proper service
procedures, and make sure the person
performing work for you
is qualified to do so.
The air bag systems do not need regular maintenance.

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem. The
system check includes the air bag sensors, the air bag
modules, the wiring and the diagnostic module. For
more information on the air bag system, see “Air Bag”
in the Index.
This light will come on
when you start your engine,
and
it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for
a few
seconds when you turn the ignition key to
ON. If the
light doesn’t come on then, have
it fixed so it will be
ready to warn you if there is a problem.
Charging System Indicator Light
El
When you turn the key
to START, this light will
come on briefly to show
that the generator and
battery charging systems are working.
If this light stays on, you need service and you should
take your vehicle to the dealer at once. To save the
battery until you get there, turn
off all accessories.
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 warning light comes on, there is a brake problem.
Have your brake system inspected right away.

Downloaded from www.Manualslib.com manuals search engine Low Coolant Warning Light
This warning light should
come on while
you are
starting the engine. If the
light doesn’t come on, have
it repaired.
I I
Your vehicle is equipped with a low coolant level sensor
(switch and float) that is designed to detect when your
vehicle’s coolant level drops below the set
limit. If the
low coolant level sensor (under the coolant surge tank)
detects that the level drops while the engine is running,
the low coolant indicator will light and remain lit until
the ignition switch
is turned off. Check the coolant level
and add coolant as needed.
The light should turn off as
soon as the coolant level
is at its proper operating range.
Malfunction Indicator Lamp
(Check Engine Light)
CHECK
ENGINE
Your vehicle is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called OBD
11 (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.

Downloaded from www.Manualslib.com manuals search engine Outside Temperature Display
The outside temperature is always displayed when your
vehicle's ignition is on. If the outside temperature
display begins to flash, this means that icy road
conditions
are possible. Adjust your driving if needed.
The display will flash for about
30 seconds and then
remain on steady.
Mode Button
Press this button to deliver air through the floor, middle
or windshield outlets. The climate control system will
stay in the selected ECC mode until the MODE button is
pressed again or until the TEMP/AUTO knob is pressed.
Press the up or down arrow to see the available modes.
EnglisWetric Display
You can change the temperature display from English
(degrees Fahrenheit) to metric (degrees Celsius) by
pressing and holding the driver's side TEMP/AUTO
knob for approximately three seconds. Repeat the
process to change back to English from metric.
Automatic Operation
Pressing the driver's side TEMP/AUTO knob sets the
system for automatic operation. Once the system is set,
sensors will control the air delivery mode. Air will come
from the floor, middle, side
or windshield outlets. The
fan speed will
vary as the system maintains the selected
temperature setting. (All previous manually set mode
settings will change back to a fully automatic mode
when the climate control system is turned on this way.)
Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.
To find your comfort zone, start with the
75 "F (24°C)
setting and allow about 20 minutes for the system to
regulate air temperature. Adjust the temperature if
necessary. If you choose
60 OF (1 6 " C), the system will
remain at that maximum cooling setting and will not
regulate fan speed. If you choose the temperature of
90" F (32"C), the system will remain at that maximum
heating setting and will not regulate fan speed. Choosing
either maximum setting will not cause the system to heat
or cool any faster.

Downloaded from www.Manualslib.com manuals search engine Brake Wear
Your vehicle has four-wheel disc brakes.
Your vehicle has electronic wear sensors that let you
know when the front brake pads are significantly worn
and new pads are needed. The brake pad wear indicator
light
will come on and stay on when the brake pads are
worn and need to be replaced. (See “Brake Pad Wear
Indicator Light” in the Index.)
I A CAUTION: I
The brake pad wear indicator light means that
soon your brakes won’t work well. That could
lead to an accident. When the brake pad wear
indicator light comes on and stays on, 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 first applied
or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel bolts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel bolts in the
proper sequence to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in the Maintenance
Schedule booklet under
Part C “Periodic Maintenance
Inspections.”
