CHEVROLET AVEO 2007 1.G Owners Manual

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 349.
Brake Wear
Your vehicle has front disc brakes and could have
rear drum brakes or rear 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 firmly.
{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 first applied or
lightly applied. This does not mean something is
wrong with the brakes.
301

Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly tighten
wheel nuts in the proper sequence to torque
specifications inCapacities and Specifications on
page 368.
If you have rear drum brakes, they do not have
wear indicators, but if you ever hear a rear brake
rubbing noise, have the rear brake linings
inspected immediately. Also, the rear brake drums
should be removed and inspected each time
the tires are removed for rotation or changing.
When you have the front brake pads replaced,
have the rear brakes inspected, too.
Brake linings should always be replaced as
complete axle sets.
SeeBrake System Inspection on page 395.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
Every time you make a moderate brake stop, the
disc brakes adjust for wear. If you rarely make
a moderate or heavier stop, then the brakes might
not adjust correctly. If you drive in that way,
then — very carefully — make a few moderate
brake stops about every 1,000 miles (1 600 km),
so the brakes will adjust properly.
If the brake pedal goes down farther than normal,
the rear drum brakes might need adjustment.
Adjust them by backing up and firmly applying the
brakes a few times.
302

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. SeeEngine Compartment Overview
on page 276for 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.
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 304for tips on working
around a battery without getting hurt.
303

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:Ignoring these steps could result in
costly damage to your vehicle that would
not be covered by your warranty.
Trying to start your vehicle by pushing or
pulling it will not work, and it could damage
your vehicle.
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.
304

To avoid the possibility of the vehicles rolling,
set the parking brake firmly on both vehicles
involved in the jump start procedure. Put
an automatic transaxle in PARK (P) or
a manual transaxle in NEUTRAL before
setting the parking brake.
Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged into
the cigarette lighter or the accessory power
outlet. Turn off the radio and all lamps that are
not needed. This will avoid sparks and help
save both batteries. And it could save
the radio!4. Open the hoods and locate the batteries. Find
the positive (+) and negative (−) terminal
locations on each vehicle. Your vehicle’s
positive (+) terminal is located under a
red tethered cap on the battery. SeeEngine
Compartment Overview on page 276for more
information on location.
Flip the cap up to access the positive (+)
terminal.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
305

{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 battery has enough water.
You do not need to add water to the
battery installed in your new vehicle. But
if a battery 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
don’t, 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
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.
306

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 not let 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 (−)
cabledoes notgo 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.
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.
307

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 Part or
Remote Negative (–) Terminal
B. Good Battery or Remote Positive (+) and
Remote Negative (−) Terminals
C. Dead Battery or Remote Positive (+) TerminalTo disconnect the jumper cables from both
vehicles, do the following:
1. Disconnect the black negative (−) cable from
the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the positive (+) terminal cap to its
original position.

Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in an accident,
the headlamp aim may be affected. Aim adjustment
to the low-beam headlamps may be necessary if it
is difficult to see the lane markers (for horizontal
aim), or if oncoming drivers flash their high-beam
headlamps at you (for vertical aim).
If you believe your headlamps need to be
re-aimed, it is recommend that you take the vehicle
to your dealer for service.
Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 317.
