light PONTIAC VIBE 2010 Repair Manual

Brakes
This vehicle has 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 the vehicle is
moving, except when applying 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 the brake wear
warning sound is heard, have the
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.
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 in
Capacities and
Specications on page 11-2 .
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
Every time the brakes are applied,
with or without the vehicle moving,
the brakes 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. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes — for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.
9-26 Vehicle Care

Brake Fluid
The brake master cylinder and, on
manual transmission vehicles, the
clutch hydraulic system use the
same reservoir. The reservoir is filled
with DOT-3 brake fluid as indicated
on the reservoir cap. SeeEngine
Compartment Overview on page 9-6
for the location of the reservoir. There are only two reasons why the
brake fluid level in the reservoir
might go down:
•The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
•A fluid leak in the brake and/or
clutch hydraulic system can also
cause a low fluid level. Have the
brake and/or clutch hydraulic
system fixed, since a leak means
that sooner or later the brakes
and/or clutch will not work well.
Do not top off the brake/clutch 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 brake fluid, as
necessary, only when work is done
on the brake/clutch hydraulic system.
{CAUTION
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 on page 4-17.

Tires
Your new vehicle comes
with high-quality tires made
by a leading tire manufacturer.
If you ever have questions about
your tire warranty and where to
obtain service, see your vehicle
Warranty booklet for details.
For additional information refer
to the tire manufacturer.
{CAUTION
Poorly maintained and improperly
used tires are dangerous.
•Overloading your tires can
cause overheating as a result
of too much flexing. You
could have an air-out and a
serious accident. See Vehicle
Load Limits on page 8-12 .
(Continued)
CAUTION (Continued)
•Underinflated tires pose the
same danger as overloaded
tires. The resulting accident
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when
your tires are cold. See Tire
Pressure on page 9-49 .
•Overinflated tires are more
likely to be cut, punctured
or broken by a sudden
impact — such as when you
hit a pothole. Keep tires at
the recommended pressure.
•Worn, old tires can cause
accidents. If your tread is
badly worn, or if your tires
have been damaged,
replace them.

and treadwear. Ratings are
determined by tire manufacturers
using government testing
procedures. The ratings are
molded into the sidewall of the
tire. See Uniform Tire Quality
Grading on page 9-58.
9-48 Vehicle Care

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warns the driver when a
low tire pressure condition exists.
TPMS sensors are mounted onto
each tire and wheel assembly,
excluding the spare tire and
wheel assembly.
When a low tire pressure condition
is detected, the low tire pressure
warning light, located on the
instrument panel cluster, comes on.This light also comes on for a
few seconds and then goes off when
you turn the ignition to ON/RUN.
This indicates the TPMS is
functioning properly. If the low-tire
pressure warning light comes on
while driving the vehicle, the system
may have detected a low-tire
condition. You need to stop as soon
as possible and check the tires.
The low tire pressure warning
light may come on in cool weather
when the vehicle is first started, and
then turn off as you start to drive.
This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be inflated
to the proper pressure.
A Tire and Loading Information
label, attached to the vehicle, shows
the size of the vehicle’s original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See
Vehicle Load
Limits on page 8-12, for an example
of the Tire and Loading Information
label and its location on your vehicle.
Also see Tire Pressure on
page 9-49.
The vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See Tire Inspection
on page 9-54, Tire Rotation on
page 9-55 andTires on page 9-43.
9-52 Vehicle Care

TPMS Malfunction Light
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire warning light flashes for
about one minute and then stays
on for the remainder of the ignition
cycle. The low tire warning light
comes on at each ignition cycle until
the problem is corrected. Some of
the conditions that can cause the
malfunction light to come on are:
•One of the road tires has been
replaced with the spare tire.
The spare tire does not have
a TPMS sensor. The TPMS
malfunction light and DIC
message should go off once
you re-install the road tire
containing the TPMS sensor.
•The initialization (reset) procedure
failed. See “TPMS Reset” later in
this section.
•One or more TPMS sensors
are missing or damaged.
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 the 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 9-56.
•Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
•If tire chains are installed on the
vehicle.
•If there is a lot of snow or ice
around the wheels or wheel
housings.
•If a window tint that affects the
radio wave signals is installed.
If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer/retailer for
service if the TPMS malfunction light
comes on and stays on.
