Downloaded from www.Manualslib.com manuals search engine To Check Brake Fluid:
You can check the brake fluid without
taking off the cap. Just look at the brake
fluid reservoir. The fluid level should be
above the plastic seam
in the reservoir.
If it isn’t, have your brake system
checked to see
if there is a leak.
After work is done on the brake hydraulic
system, make sure the level
is above the
plastic seam, near the base of the filler
neck.
What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid
- such as Delco-
Supreme 1 l@ (GM Part No. 1052535).
Use new brake fluid from a sealed container
only, and always clean the brakt
fluid reservoir cap before removing it.
NOTICE:
0 Don’t let someone put in the
wrong kind
of fluid. For example,
just a few drops
of mineral-based
oil, such as engine oil, in your
brake system can damage brake
system parts
so badly that they’ll
have to be replaced.
0 Brake fluid can damage paint, so
be careful not to spill brake fluid
on your vehicle.
If you do, wash it
off immediately. See ”Appearance
Care”
in the Index.
Brake Wear
Unless you have the four-wheel disc
brake option, your Chevrolet has front
disc brakes and rear drum 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 may come and go or be heard all
the time your vehicle is moving (except when
you are
pushing on the brake pedal
firmly).
A CAUTION:
The brake wear warning sound
means that sooner or later your
brakes won’t 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 may
cause
a brake squeal when the brakes are
first applied or lightly applied. This does
not mean something is wrong
with your
brakes.

Halogen Bulbs Headlights
Headlight Aiming
Your
vehicle has a mini-quad headlight
system. These headlights have vertical
and horizontal indicators. When the
headlights are properly installed and
adjusted, and the vehicle is on level
ground, both indicators will read in the
:enter of the gage.
If they do not, you can
adjust the aim.
To adjust the aim of your headlights:
1. Move your vehicle to a level surface.
Use a spirit level to be sure. Be sure to
remove any items that are not part of
your original equipment from the
trunk and passenger areas.
No one
should be seated
in the vehicle and
your fuel tank should be about half
full. Check to be sure your tires are at
the correct pressure.

When to Check: Check your tires once a
month or more. Don’t forget your
compact spare tire. It should be at
60 psi
(420 kPa).
How to Check: Use a good quality
pocket-type gage to check tire pressure.
Simply looking at the tires will not tell
you the pressure, especially if you have
radial tires
- which may look properly
inflated even
if they’re underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture. Tire Inspection and Rotation
To make your tires last longer, have them
inspected and rotated at the mileages
recommended
in the Maintenance
Schedule. See “Scheduled Maintenance
Services” in the Index.
[f you don’t have P245/50ZR16 size tires
use the rotation pattern shown above for
your size tires.
4-
f you have P245/50ZR16 size tires, they
nust roll in
a certain direction for the best
werall performance. The direction is
hown by an arrow on both sidewalls.
3ecause these tires are directional, they
hould be rotated as shown
in the
:xample above. These tires should only
,e moved from front to rear and rear to
ront on the same side of the vehicle.
ifter the tires have been rotated, adjust
he front and rear inflation pressure as
.hown on
the Tire-Loading Information
abel. Make certain that all wheel nuts are
u-operly tightened. See “Wheel Nut
rorque” in the Index.

Downloaded from www.Manualslib.com manuals search engine When It’s Time for New Tires
One way to tell when it’s time for new
tires is to check the treadwear indicators,
which
will appear when your tires have
only
2/32 inch (1.6 mm) or less of tread
remaining.
You need a new tire if:
0 You can see the indicators at three or
more places around the tire.
0 You can see cord or fabric showing
through
the tire’s rubber.
The tread or sidewall is cracked, cut
or snagged deep enough to show cord
or fabric.
0 The tire has a bump, bulge or split. The tire
has a puncture, cut, or other
damage that can’t be repaired
well
because of the size or location of the
damage.
Buying New Tires
To find out what kind and size of tires you
need, look at the Tire-Loading
Information label.
The tires installed on your vehicle when it
was new had a Tire Performance Criteria
Specification (TPC Spec) number on each
tire’s sidewall. When you get new tires,
get ones
with that same TPC Spec
number. That way, your vehicle
will
continue to have tires that are designed to
give proper endurance, handling, speed
rating, traction, ride and other things
during normal service on your vehicle. If
your tires have an all-season tread design,
the TPC number
will be followed by a
“MS” (for mud and snow).
If you ever replace your tires with those
not having a TPC Spec number, make
sure they are the same size, load range,
speed rating and construction type (bias,
bias-belted or radial) as your original
tires.

Keep belts clean and dry.
A CAUTION:
Do not bleach or dye safety belts.

because they may cause scratches. Avoid
placing decals on the inside rear window,
since they
may have to be scraped off
later. If abrasive cleaners are used on the
inside of the rear window, an electric
defogger element may be damaged.
Any
temporary license should not be attached
across the defogger grid.

Washing Your Vehicle
The best way to preserve your vehicle’s
finish is to keep
it clean by washing it
often with lukewarm or cold water.
Don’t wash your vehicle
in the direct
rays of the sun. Don’t use strong soaps
or chemical detergents. Use liquid hand,
dish
or car washing (mild-detergent)
soaps. Don’t use cleaning agents that are
petroleum based, or contain acid or
abrasives.
All cleaning agents should be
flushed promptly and not allowed to
dry
on the surface, or they could stain. Dry
the finish
with a soft, clean chamois or
a
100% cotton towel to avoid surface
scratches and water spotting.
High pressure car washes may cause
water to enter your vehicle.
