VEHICLE CARE 301
The brake master cylinder reservoir is
filled with GM approved DOT 4 brake
fluid as indicated on the reservoir cap.
SeeEngine Compartment Overview
0 289 for the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a level
surface, the brake fluid level should be
between the minimum and maximum
marks on the brake fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.Normal brake lining wear. When
new linings are installed, the fluid
level goes back up.
.A fluid leak in the brake hydraulic
system. Have the brake hydraulic
system fixed. With a leak, the
brakes will not work well.
Always clean the brake fluid reservoir
cap and the area around the cap
before removing it.
Do not top off the brake fluid. Adding
fluid does not correct a leak. If fluid is
added when the linings are worn,
there will be too much fluid when
new brake linings are installed. Add or remove fluid, as necessary, only when
work is done on the brake hydraulic
system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You or
others could be burned, and the
vehicle could be damaged. Add
brake fluid only when work is done
on the brake hydraulic system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning Light
0 108.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid at
the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0368.
What to Add
Use only GM approved DOT 4 brake
fluid from a clean, sealed container.
See Recommended Fluids and
Lubricants 0377.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the paint
finish can be damaged. Immediately
wash off any painted surface.
Battery - North America
The original equipment battery is
maintenance free. Do not remove the
cap and do not add fluid.
Refer to the replacement number
shown on the original battery label
when a new battery is needed. See
Engine Compartment Overview 0289
for battery location.

VEHICLE CARE 307
Electrical System
Electrical System Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is too
heavy, the circuit breaker opens and
closes, protecting the circuit until the
current load returns to normal or the
problem is fixed. This greatly reduces
the chance of circuit overload and fire
caused by electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be borrowed.
Choose some feature of the vehicle
that is not needed to use and replace
it as soon as possible.
To check a fuse, look at the band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure to
replace a bad fuse with a fuse of the
identical size and rating.
Replacing a Blown Fuse
1. Turn off the vehicle.
2. Locate the fuse puller in the enginecompartment fuse block.

(5) Tire Inf lation:The temporary
use tire or compact spare tire
should be inflated to 420 kPa
(60 psi). For more information on
tire pressure and inflation see Tire
Pressure 0325.
(6) Tire Size
:A combination of
letters and numbers define a tire's
width, height, aspect ratio,
construction type, and service
description. The letter “T”as the
first character in the tire size
means the tire is for temporary
use only.
(7) TPC Spec (Tire Performance
Criteria Specification)
:Original
equipment tires designed to GM's
specific tire performance criteria
have a TPC specification code
molded onto the sidewall. GM's
TPC specifications meet or exceed
all federal safety guidelines.
Tire Designations
Tire Size
The example shows a typical
passenger vehicle tire size.
Passenger (P-Metric) Tire
(1) Passenger (P-Metric) Tire:
The United States version of a
metric tire sizing system. The
letter "P" as the first character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire and
Rim Association.
(2) Tire Width
:The 3-digit
number indicates the tire section
width in millimeters from sidewall
to sidewall. (3) Aspect Ratio
:A 2-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size aspect
ratio is 75, as shown in item (3) of
the illustration, it would mean
that the tire's sidewall is
75 percent as high as it is wide.
(4) Construction Code
:A letter
code is used to indicate the type
of ply construction in the tire. The
letter "R" means radial ply
construction; the letter "D" means
diagonal or bias ply construction.
(5) Rim Diameter
:Diameter of
the wheel in inches.
(6) Service Description
:These
characters represent the load
index and speed rating of the tire.
The load index represents the load
carrying capacity a tire is certified
to carry. The speed rating is the
maximum speed a tire is certified
to carry a load.

Warning (Continued)
blowout and a serious crash. Never
attempt to re-inflate a tire that has
been driven on while severely
underinflated or flat. Have your
dealer or an authorized tire service
center repair or replace the flat tire
as soon as possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it
is designed only for changing a flat
tire. If it is used for anything else,
you or others could be badly injured
or killed if the vehicle slips off the
jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road, if possible. Turn on the hazard
warning flashers. See
Hazard Warning
Flashers 0132.
{Warning
Changing a tire can be dangerous.
The vehicle can slip off the jack and
roll over or fall causing injury or
death. Find a level place to change
the tire. To help prevent the vehicle
from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission in P (Park) or a manual
transmission in 1 (First) or
R (Reverse).
3. Turn off the engine and do not restart while the vehicle is
raised.
4. Do not allow passengers to remain in the vehicle.
5. Place wheel blocks, if equipped, on both sides of the tire at the
opposite corner of the tire
being changed. This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. To use the jacking
equipment to change a spare tire
safely, follow the instructions below.
Then see
Tire Changing 0346. To use
the tire sealant and compressor kit,
see Tire Sealant and Compressor Kit
0 340.
When the vehicle has a flat tire (2),
use the following example as a guide
to assist you in the placement of
wheel blocks (1), if equipped.

Tire Sealant and
Compressor Kit
{Warning
Idling a vehicle in an enclosed area
with poor ventilation is dangerous.
Engine exhaust may enter the
vehicle. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death. Never run the engine in an
enclosed area that has no fresh air
ventilation. For more information,
seeEngine Exhaust 0226.
{Warning
Overinflating a tire could cause the
tire to rupture and you or others
could be injured. Be sure to read
and follow the tire sealant and
compressor kit instructions and
inflate the tire to its recommended
pressure. Do not exceed the
recommended pressure.
{Warning
Storing the tire sealant and
compressor kit or other equipment
in the passenger compartment of
the vehicle could cause injury. In a
sudden stop or collision, loose
equipment could strike someone.
Store the tire sealant and
compressor kit in its original
location.
If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire or tire changing equipment,
and on some vehicles there may not
be a place to store a tire.
The tire sealant and compressor can
be used to temporarily seal punctures
up to 6 mm (0.25 in) in the tread area
of the tire. It can also be used to
inflate an underinflated tire.
If the tire has been separated from the
wheel, has damaged sidewalls, or has
a large puncture, the tire is too
severely damaged for the tire sealant
and compressor kit to be effective. See
Roadside Service 0388. Read and follow all of the tire sealant
and compressor kit instructions.
The kit includes:
1. Sealant Canister Inlet Valve
2. Sealant/Air Hose
3. Base of Sealant Canister
4. Tire Sealant Canister
5. On/Off Button
6. Slot on Top of Compressor
7. Pressure Deflation Button
