Adding Washer Fluid
When the windshield washer uid
reservoir is low, a WASHER FLUID
LOW ADD FLUID message will be
displayed on the Driver Information
Center (DIC). SeeDIC Warnings and
Messages on page 3-48for more
information.
Open the cap with the washer
symbol on it. Add washer uid until
the tank is full. SeeEngine
Compartment Overview on
page 5-10for reservoir location.Notice:When using concentrated
washer uid, follow the
manufacturer’s instructions
for adding water.
Do not mix water with
ready-to-use washer uid.
Water can cause the solution to
freeze and damage your washer
uid tank and other parts of the
washer system. Also, water
does not clean as well as
washer uid.
Fill the washer uid tank only
three-quarters full when it is
very cold. This allows for uid
expansion if freezing occurs,
which could damage the tank if
it is completely full.
Do not use engine coolant
(antifreeze) in your windshield
washer. It can damage the
vehicle’s windshield washer
system and paint.
Brakes
Brake Fluid
The brake master cylinder reservoir
is lled with DOT-3 brake uid. See
Engine Compartment Overview on
page 5-10for the location of the
reservoir.
There are only two reasons why the
brake uid level in the reservoir
might go down:
The brake uid level goes down
because of normal brake lining
wear. When new linings are
installed, the uid level goes
back up.
5-24 Service and Appearance Care

A uid leak in the brake hydraulic
system can also cause a low uid
level. Have the brake hydraulic
system xed, since a leak means
that sooner or later the brakes will
not work well.
Do not top off the brake uid. Adding
uid does not correct a leak. If uid is
added when the linings are worn,
there will be too much uid when new
brake linings are installed. Add or
remove brake uid, as necessary,
only when work is done on the brake
hydraulic system.
{CAUTION
If too much brake uid 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 uid only when work is done
on the brake hydraulic system.When the brake uid falls to a low
level, the brake warning light comes
on. SeeBrake System Warning
Light on page 3-33.
What to Add
Use only new DOT-3 brake uid
from a sealed container. See
Recommended Fluids and
Lubricants on page 6-12.
Always clean the brake uid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering
the reservoir.{CAUTION
With the wrong kind of uid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake uid.Notice:
Using the wrong uid
can badly damage brake
hydraulic system parts. For
example, just a few drops
of mineral-based oil, such
as engine oil, in the brake
hydraulic system can damage
brake hydraulic system
parts so badly that they will
have to be replaced. Do not let
someone put in the wrong
kind of uid.
If brake uid is spilled on the
vehicle’s painted surfaces, the
paint nish can be damaged. Be
careful not to spill brake uid
on the vehicle. If you do, wash it
off immediately. SeeWashing
Your Vehicle on page 5-86.

4. Open the hoods and locate the
positive (+) and negative (−)
terminal locations on the other
vehicle. Your vehicle has a
remote positive (+) and a
remote negative (−) jump
starting terminal. SeeEngine
Compartment Overview on
page 5-10for more information
on the terminal locations.
{CAUTION
Using a match near a battery can
cause battery gas to explode.
People have been hurt doing this,
and some have been blinded. Use
a ashlight if you need more light.
Be sure the batteries have
enough water. You do not need to
add water to the ACDelco
®
battery (or batteries) installed in
your new vehicle. But if a battery
(Continued)
CAUTION (Continued)
has ller caps, be sure the right
amount of uid is there. If it is
low, add water to take care of that
rst. If you do not, explosive gas
could be present.
Battery uid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, ush
the place with water and get
medical help immediately.
{CAUTION
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.5. Check that the jumper cables do
not have loose or missing
insulation. If they do, you could
get a shock. The vehicles
could be damaged too.
Before you connect the cables,
here are some basic things you
should know. Positive (+) will go
to positive (+) or to a remote
positive (+) terminal if the vehicle
has one. Negative (−) will go to a
heavy, unpainted metal engine
part or to a remote negative (−)
terminal if the vehicle has one.
Do not connect positive (+) to
negative (−) or you will get
a short that would damage the
battery and maybe other
parts too. And do not connect
the negative (−) cable to
the negative (−) terminal on the
dead battery because this
can cause sparks.
Service and Appearance Care 5-29

6. Connect the red positive (+)
cable to the positive (+) terminal
of the dead battery.
Use a remote positive (+)
terminal if the vehicle has one.
7. Do notlet the other end touch
metal. Connect it to the
positive (+) terminal of the good
battery. Use a remote positive (+)
terminal if the vehicle has one.8. Now connect the black
negative (−) cable to the
negative (−) terminal of the
good battery. Use a remote
negative (−) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step. The
other end of the negative (−)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part, or to
a remote negative (−) terminal on
the vehicle with the dead battery.9. Connect the other end of the
negative (−) cable at least
18 inches (45 cm) away from the
dead battery, but not near
engine parts that move.
The electrical connection is just
as good there, and the chance
of sparks getting back to the
battery is much less.
Your vehicle has a remote
negative (−) terminal for this
purpose.
5-30 Service and Appearance Care

10. Now start the vehicle with the
good battery and run the
engine for a while.
11. Try to start the vehicle that had
the dead battery. If it will not
start after a few tries, it probably
needs service.
Notice:If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by your warranty. Always
connect and remove the jumper
cables in the correct order,
making sure that the cables do not
touch each other or other metal.A. Heavy, Unpainted Metal Engine

(F) Tire Size:A combination of
letters and numbers dene a
tire’s width, height, aspect ratio,
construction type, and service
description. The letter T as
the rst character in the tire size
means the tire is for temporary
use only.
(G) TPC Spec (Tire
Performance Criteria
Specication)
:Original
equipment tires designed to
GM’s specic tire performance
criteria have a TPC specication
code molded onto the sidewall.
GM’s TPC specications meet or
exceed all federal safety
guidelines.Tire Size
The following illustration shows
an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire
:The United States version of a
metric tire sizing system. The
letter P as the rst character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association.
(B) Tire Width
:The three-digit
number indicates the tire
section width in millimeters from
sidewall to sidewall.
(C) Aspect Ratio
:A two-digit
number that indicates the tire
height-to-width measurements.For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire’s sidewall is
60 percent as high as it is wide.
(D) 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;
and the letter B means
belted-bias ply construction.
(E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Service Description
:These
characters represent the load
range and speed rating of the
tire. The load index represents
the load carry capacity a tire is
certied to carry. The load index
can range from 1 to 279. The
speed rating is the maximum
speed a tire is certied to carry
a load. Speed ratings range
fromAtoZ.
Service and Appearance Care 5-39

One or more TPMS sensors
are missing or damaged.
The DIC message and the
TPMS malfunction light should
go off when the TPMS sensors
are installed and the sensor
matching process is performed
successfully. See your dealer/
retailer for service.
Replacement tires or wheels do
not match your vehicle’s original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 5-50.
Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer/ retailerfor service if the TPMS malfunction
light and DIC message comes
on and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identication code. Any time you
rotate your vehicle’s tires or replace
one or more of the TPMS sensors,
the identication codes will need to
be matched to the new tire/wheel
position. The sensors are matched to
the tire/wheel positions in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear tire
using a TPMS diagnostic tool. See
your dealer/ retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire’s air pressure. If increasing the
tire’s air pressure, do not exceed
the maximum ination pressure
indicated on the tire’s sidewall.To decrease air-pressure out of a
tire you can use the pointed
end of the valve cap, a pencil-style
air pressure gage, or a key.
You have two minutes to match
the rst tire/wheel position, and
ve minutes overall to match all
four tire/wheel positions. If it takes
longer than two minutes, to match
the rst tire and wheel, or more than
ve minutes to match all four tire
and wheel positions the matching
process stops and you need to
start over.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
Service and Appearance Care 5-47

If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place and stopping.
1. Turn on the hazard warning

Changing a Flat Tire
If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning ashers. SeeHazard
Warning Flashers on page 3-5.
{CAUTION
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall on
you or other people. You and they
could be badly injured or even
killed. Find a level place to
change your tire. To help prevent
the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in
P (Park).

CAUTION (Continued)
3. Turn off the engine and do
not restart while the vehicle
is raised.
4. Do not allow passengers to
remain in the vehicle.
To be even more certain the
vehicle will not move, you should
put blocks at the front and rear of
the tire farthest away from the
one being changed. That would
be the tire, on the other side, at
the opposite end of the vehicle.When the vehicle has a at tire (B),
use the following example as a
guide to assist you in the placement
of wheel blocks (A).
