Engine Air Cleaner/Filter
(Gasoline Engines)
Your engine air cleaner/filter is located between the
battery and coolant recovery tank. See ªEngine
Compartment Overviewº in the Index for more
information on location.
The engine air cleaner/filter
assembly has an indicator
that lets you know when
the engine air cleaner/filter
is dirty and needs to
be serviced.
The indicator is located in the air intake tube between
the engine air cleaner/filter and the engine. See ªEngine
Compartment Overviewº in the Index for more
information on location.
See ªOwner Checks and Servicesº in the Index to
determine when to check the indicator.
If the area inside the clear section of the indicator is
green, no engine air cleaner/filter service is required.
When the area inside the indicator is orange and
CHANGE AIR FILTER appears, the filter should
be replaced.

6-34 Replacing Brake System Parts
The braking system on a vehicle is complex.
Its many parts have to be of top quality and work
well together if the vehicle is to have really good
braking. Your vehicle was designed and tested with
top
-quality GM brake parts. When you replace
parts of your braking system
-- for example, when
your brake linings wear down and you need new ones
put in
-- be sure you get new approved GM replacement
parts. If you don't, your brakes may no longer work
properly. For example, if someone puts in brake linings
that are wrong for your vehicle, the balance between
your front and rear brakes can change
-- for the worse.
The braking performance you've come to expect can
change in many other ways if someone puts in the
wrong replacement brake parts.
Battery
Your new vehicle comes with a maintenance free
ACDelco
battery. When it's time for a new battery,
get one that has the replacement number shown on the
original battery's label. We recommend an ACDelco
battery. See ªEngine Compartment Overviewº in the
Index for battery location.
WARNING: Battery posts, terminals and related
accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.

6-35 Vehicle Storage
If you're not going to drive your vehicle for 25 days
or more, remove the black, negative (
-) cable from
the battery. This will help keep your battery from
running down.
CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº in the Index
for tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Bulb Replacement
For any bulb changing procedure not listed in this
section, contact your dealer. See ªReplacement Bulbsº
in the Index for the proper types of bulbs to use.
Halogen Bulbs
CAUTION:
Halogen bulbs have pressurized gas inside
and can burst if you drop or scratch the bulb.
You or others could be injured. Be sure to read
and follow the instructions on the bulb package.
