Accessories and Modications
When you add non-GM accessories to your vehicle
they can affect your vehicle’s performance and
safety, including such things as, airbags, braking,
stability, ride and handling, emissions systems,
aerodynamics, durability, and electronic systems
like anti-lock brakes, traction control and
stability control. Some of these accessories may
even cause malfunction or damage not covered
by warranty.
GM Accessories are designed to complement
and function with other systems on your vehicle.
Your GM dealer/retailer can accessorize your
vehicle using genuine GM Accessories. When
you go to your GM dealer/retailer and ask for
GM Accessories, you will know that GM-trained
and supported service technicians will perform
the work using genuine GM Accessories.

Checking Engine Oil (Except Z06)
If the CHECK OIL LEVEL message on the Driver
Information Center (DIC) comes on, check the
engine oil level right away. For more information,
seeDriver Information Center (DIC) on page 207.
You should check the engine oil level regularly;
this is an added reminder.
It is a good idea to check the engine oil level
every time you get fuel. In order to get an accurate
reading, the oil must be warm and the vehicle
must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 330
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few
minutes to drain back into the oil pan. If
you do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a
lint-free paper towel or a cloth, then push
it back in all the way. Remove it again,
keeping the tip down.

Brakes
Brake Fluid
The brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 330for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake system. If it is, you should have the
brake system xed, since a leak means that
sooner or later the brakes will not work well.So, it is not a good idea to top off the brake
uid. Adding brake uid will not correct a leak.
If you add uid when the linings are worn,
then you will have too much uid when you get
new brake linings. You should add or remove
brake uid, as necessary, only when work is
done on the brake hydraulic system.
{CAUTION:
If you have too much brake uid, it can
spill on the engine. The uid will burn if
the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake hydraulic
system. See “Checking Brake Fluid” in
this section.
Refer to the Maintenance Schedule to determine
when to check the brake uid. SeeScheduled
Maintenance on page 433.
361

Checking Brake Fluid
You can check the brake uid without taking
off the cap. Look at the brake uid reservoir.
The uid level should be above the MIN mark on
the reservoir. If it is not, have the brake system
checked to see if there is a leak.
After work is done on the brake hydraulic system,
make sure the level is between the MIN and
MAX marks.
What to Add
When you do need brake uid, use only DOT-3
brake uid. Refer toRecommended Fluids
and Lubricants on page 443. Use new brake
uid from a sealed container only.
Always clean the brake uid reservoir cap and
the area around the cap before removing it. This
will help keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake
system, the brakes may not work well.
This could cause a crash. Always use the
proper brake uid.
Notice:
Using the wrong uid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in the brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 411.

Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound can come and go or be heard all
the time your vehicle is moving, except when you
are pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.
Some driving conditions or climates can cause
a brake squeal when the brakes are rst applied
or lightly applied. This does not mean something
is wrong with the brakes.
Brake linings should always be replaced as
complete axle sets.
Brake Pedal Travel
See your dealer/retailer if the brake pedal does
not return to normal height, or if there is a
rapid increase in pedal travel. This could be a
sign that brake service might be required.
Brake Adjustment
As you make brake stops, the disc brakes
automatically adjust for wear.

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 brake parts. When you replace
parts of the braking system — for example, when
the brake linings wear down and you need new
ones put in — be sure you get new approved
replacement parts. If you do not, the brakes might
not work properly. For example, if someone puts
in brake linings that are wrong for your vehicle,
the balance between the front and rear brakes can
change — for the worse. The braking performance
you have come to expect can change in many other
ways if someone puts in the wrong replacement
brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that
has the replacement number shown on the
original battery’s label. We recommend an
ACDelco
®replacement battery.For battery replacement, see your dealer or the
service manual. To purchase a service manual,
seeService and Owner PublicationsinService
Publications Ordering Information on page 468.
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.
Vehicle Storage
If you are 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 are not careful. SeeJump
Starting on page 365for tips on working
around a battery without getting hurt.
364

Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start
your vehicle. Be sure to use the following steps to
do it safely.
{CAUTION:
Batteries can hurt you. They can be
dangerous because:
They contain acid that can burn you.
They contain gas that can explode
or ignite.
They contain enough electricity
to burn you.
If you do not follow these steps exactly,
some or all of these things can hurt you.
Notice:If you try to start your vehicle by
pushing or pulling it, you could damage your
vehicle. Do not push or pull your vehicleto start it; instead, use the jump starting
procedure in this manual to start your vehicle
when the battery has run down.
1. Check the other vehicle. It must have a
12-volt battery with a negative ground system.
Notice:If the other vehicle’s system is not
a 12-volt system with a negative ground, both
vehicles can be damaged. Only use vehicles
with 12-volt systems with negative grounds to
jump start your vehicle.
2. Get the vehicles close enough so the jumper
cables can reach, but be sure the vehicles
are not touching each other. If they are,
it could cause a ground connection you do
not want. You would not be able to start
your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling,
set the parking brake rmly on both vehicles
involved in the jump start procedure. Put
an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brakes.
